Project Background
The Crux gas field is in the Australian Commonwealth waters, within permit AC/RL9 in the East Browse
basin. The title is operated by COMPANY (82% equity) on behalf of the other joint venture participants
SGH Energy (15%) and Osaka Gas (3%).
The field lies in approximately 165m of water depth, 620km NNE of Broome (~300km from mainland
Australia). The title is surrounded by COMPANY operated AC/P-41 title (COMPANY equity 75%) that
incorporates the Libra gas field and is located approximately 160km NE of COMPANY operated Prelude
Asset (Prelude FLNG).
A Not Normally Manned (NNM) platform at the Crux field (Crux NNM platform) will be tied back to the
Prelude Asset through an approximate 160km multiphase export pipeline. The export pipeline shall
interface with the Prelude Asset through a 16” ID flexible riser. The subsea isolation valve on the associated
riser base structure shall be controlled through a dedicated dynamic umbilical from the Prelude Asset.
The Crux field location map is presented in Figure 1.

5.2
Mechanical Completion Hierarchy
In order to achieve a correctly documented MC Handover from SUBCONTRACTOR Construction
to ICT all Systems are divided to form Sub-Systems which further transcend to Discipline
packages.
Systems
Defined Systems have been allocated a number by the Integrated Commissioning Team – Pre
Execution personnel which transcends down to numbering of the Sub- Systems.
Sub-Systems
A Sub-System is the boundary of equipment which has been conveniently grouped for the purposes
of dividing the larger systems into more manageable sections for MC and Pre- Commissioning.
Each Sub System shall be allocated a number by SUBCONTRACTOR which shall relate to
systems module. Every item of equipment within each Sub System e.g. piping, cables instruments
etc. shall be referred to by its allocated unique project tag number.
Discipline Packages
Discipline packages within a Sub-System have been allocated to further divide the Sub- Systems
and have been provided with individual Discipline identifications. When all the Discipline
packages within a Sub-System are agreed by the ICT as mechanically complete, the larger SubSystem by definition is considered to be mechanically complete.
MC – ITR’s
The listing of equipment shall be further broken down into individual Mechanical Completion
Records (MC-ITRs) which identify test and inspection requirements for each item of equipment.
Title: MECHANICAL COMPLETION EXECUTION PLAN
5.3
Boundary Documents
The boundary limits of Sub Systems shall initially be identified by SUBCONTRACTOR
Commissioning Team on marked up P&ID's, Layout Drawings, Instrument Block Diagram and
Electrical Single Line Drawings. The boundary limits shall be reviewed and agreed with
CONTRACTOR Completions Team prior to final approval.
On completion of approved System/Sub System boundaries all equipment within the established
Sub System limits shall be listed including in line and remote instruments, associated power and
control cables by type and number.
5.4
System / Sub-System Priorities
Sub-System priorities for completion have been identified by the ICT. At the correct point in time
SUBCONTRACTOR will define Systems and Sub-Systems within the Work Breakdown Structure
of their Level 03 Construction Execution Schedule and present proposed MC Handover dates and
MC ‘skyline’ charts to ICT for approval.
These documents will reflect the handover priorities requested by the ICT and will establish a
progressive handover flow in a sequence supporting the defined System / Sub- System priorities.

Title: MECHANICAL COMPLETION EXECUTION PLAN
MC HANDOVER DOCUMENTATION RESPONSIBILITY SPLIT
The MC Flow Chart (Figure 3) demonstrates the progression and signatory responsibilities of MCITR’s from issue through to MC-ITR completion. Once all the MC-ITR’s within a Sub-system /
Discipline are completed the MC-DACs are generated for acceptance and sign off.
The MC-DACs are then accumulated appropriately and the MC-SSACs are generated for
acceptance and sign off by the Integrated Commissioning Team (ICT).
7.1
Signatory Authority
As shown on the MC Flow Chart in Figure 3 a hierarchical arrangement of
SUBCONTRACTORConstruction / QC / MC personnel positions and CONTRACTOR
Completions personnel positions are accountable for signing-off the sub-level hierarchy of MC
certification.
In general, all MC documentation will be countersigned by both SUBCONTRACTORand
CONTRACTOR. An exception may be made for MC-ITRs where the MC-ITR is not called for as
a CONTRACTOR hold/witness/inspect point by QC ITPs. In that instance MC-ITRs may be both
completed and accepted by Contractor only. Identification of these MC-ITRs will be provided by
CONTRACTOR.
The following signatory authority tables cross-reference those positions within the structured
arrangement of accountabilities for ensuring compliance with workmanship quality,
documentation accuracy, completeness and co-ordination of certification flow through to full MC
of the Jacket.
On signing certification, the SUBCONTRACTORConstruction / QA / MC signatory authority is
stating they have personally monitored, witnessed, reviewed the workmanship and dossier contents
involved with the specific scope and that all are of an acceptable standard.
CONTRACTOR Completions team will sign as a verification / acceptance function.
Throughout the full construction and mechanical completion process of Jacket both
SUBCONTRACTOR and CONTRACTOR will work on the basis that:
“Whoever has undertaken the work will have signed the documentation and is fully responsible
for the scope it covers”

During and after completion review of the specific Construction scope it is necessary that each
inspection line item on the particular MC-ITR is addressed with either "OK” or "P/L" or "N/A"
comment. While completing the MC-ITR any item necessitating a "P/L" must be then identified
on a Punchlist Form.
MC Note: Idemitsu Completions Team shall only sign off on MC-ITR’s where they have been in
attendance and witnessed the inspections / testing as identified on the MC-ITR. Any MC-ITRs not
signed by Idemitsu Completions Team within that Sub-system shall be reviewed during the MCDAC and MC-SSAC dossier review with relevant comments added if required. This process has
been discussed and agreed with the Idemitsu Commissioning and Operations Teams.
MC-ITR Completion Flowchart
The flowchart in Figure 4 is intended to demonstrate the process related to satisfactory completion
of MC-ITRs from start to finish and includes requirements for P/Ls and signatory approvals.
For Construction quality of work craft and standard of MC-ITR paperwork the process should
enforce completeness and value while accurately capturing any scope that does not conform to
specification and cannot be immediately remedied.
MC-ITR Queries
SUBCONTRACTOR Construction/ QC Team MC-ITR queries regarding the check necessary for
any particular item of equipment, shall be referred to the Integrated Commissioning Team.
Any future additions, deletions or amendments to MC-ITRs shall require approval by the
Integrated Commissioning Team who shall maintain responsibility for issuing and recording MCITR alterations.
Note: Although MC-ITRs are necessary evidence of work completion, they are not intended to
supersede, modify or vary contractual agreements.
The MC-ITR for pumps, motors, vessels etc. shall list the checks that are normally
performed upon that type of equipment but may not be specifically written for each
particular item of equipment. Where additional information is required to be included for
the equipment the comments section of the ITR should be used.
Title: MECHANICAL COMPLETION EXECUTION PLAN
All inspection and test equipment used for measurement shall be calibrated to a national
standard with a full list of test equipment and current calibration details submitted to
CONTRACTOR Quality Control Team and maintained by SUBCONTRACTORQuality
Control Team.

The Mechanical Completion Discipline Acceptance Certificate (MC-DAC)
On completion of all MC-ITRs within a discipline package within a Sub-System the Discipline
Acceptance Certificate (MC-DAC) will be issued for SUBCONTRACTOR Construction / QC
offer to Integrated Commissioning Team for acceptance.
The CA’s / CONTRACTOR Commissioning representative will be invited to participate in all MC
activities at site including all MC walk downs and final MC inspections.
SUBCONTRACTOR Construction/ QC Team and Integrated Commissioning Team will carry out
a joint physical review of the offered Discipline package. Attendance at the review by these groups
is mandatory.
Where SUBCONTRACTOR Construction/ QC Team and Integrated Commissioning Team review
of the MC-DAC offering reveals that the requirements of the associated MC-ITRs, Design
Specifications or Drawings have not been achieved SUBCONTRACTOR Construction shall
rectify the work and shall re-submit that item(s) of work/ MC-ITR(s) for approval and for the
consortium to review again.
Only when all associated Discipline package MC-ITRs have been completed shall a MC-DAC be
considered 'Mechanically Complete' and accepted by the CONTRACTOR.
8.2.1
MC-DAC Sign Off Authority
As shown on the MC-DAC Signatory Authority Tables, signatories for the MC-DACs shall be
completed by SUBCONTRACTOR Construction Team and accepted by SUBCONTRACTOR
Commissioning Team & CONTRACTOR Commissioning Team. For the Non-Commissionable
Systems, MC-DACs shall be completed by SUBCONTRACTOR Construction Team, verified by
SUBCONTRACTOR QC Team and accepted by CONTRACTOR Completion Team.
When, if material shortage or outstanding design changes prevent completion of certain MC- ITRs
within the Sub-System MC-DAC, then a punchlist can be raised and agreed between
SUBCONTRACTOR Construction/ QC Teams, SUBCONTRACTOR Commissioning Team and
CONTRACTOR Commissioning Team or nominated persons. The Integrated Commissioning
Title: MECHANICAL COMPLETION EXECUTION PLAN
Team will ensure all/any outstanding / rectification work accepted for carry-forward is accurate
and detailed on the P/L associated with the MC-DAC.
In general MC-DAC Punchlists shall contain only ‘B’ items and will be kept to an absolute
minimum.
8.2.2
Partial MC-DAC
During the Mechanical Completion phase there may be instances where a partial handover of a
Sub-System Discipline (MC-DAC) is required, albeit by exception and not as the norm. This would
typically be related to Lighting & Small Power Circuits, PAGA Speaker Loops etc. where the
entire limit of the full Sub-System handover may not be available. On condition that all individual
components and associated MC-ITRs identified for that particular part of the Sub-System to be
handed over have been completed then a partial MC-DAC shall be raised and approved. This
partial MC-DAC will clearly identify with marked up revised boundary documents identifying the
limits of the proposed handover of the “partial Sub-System”. Also attached will be a CMS Status
Report listing the components which have successfully passed the inspection & testing
requirements to facilitate handover and energization of the equipment using the project approved
procedures.
The partial MC-DAC will be processed and signed by all personnel as would be a full MC-DAC,
upon completion of all remaining components within the Sub-System then a full MC-DAC will be
raised and signed.
8.3
The Mechanical Completion Sub-System Acceptance Certificate (MC-SSAC)
When all MC-DACs are complete within a Sub-System the MC-SSAC will be issued for
SUBCONTRACTOR Construction/ QC Team to offer the Mechanically Complete Sub-System to
the Integrated Commissioning Team for review and acceptance. For the Non- Commissionable
Sub-Systems, MC-SSACs shall be completed by SUBCONTRACTOR Construction Team,
verified
by
SUBCONTRACTOR
QC
Team
and
accepted
by
CONTRACTOR
Completion/Operation team.
The Dossier complementing the MC-SSAC will be complete with a computer printed list detailing
all Sub-System associated completed MC-ITRs and MC-DACs with any outstanding punch-list
items and modified ‘Red-Line’ drawings.
SUBCONTRACTOR and CONTRACTOR Construction / QC Team will carry out a joint review
of the offered Sub-System and documentation alongside the Integrated Commissioning Team.
Title: MECHANICAL COMPLETION EXECUTION PLAN
Where the Integrated Commissioning Team review of the MC-SSAC dossier reveals that the
requirements of the associated MC-ITRs, Design Specifications or Drawings have not been
achieved, SUBCONTRACTOR Construction shall rectify the work and shall re-submit that item
of work(s) / MC-ITR(s) for approval and the consortium to review again.
Only when all Sub-System MC-ITRs and MC-DACs have been completed shall a MC-SSAC be
considered 'Mechanically Complete' and accepted by CONTRACTOR.
8.3.1
MC-SSAC Sign Off Authority
As shown on the MC-SSAC Signatory Authority Tables, signatories for the MC-SSACs will be
from SUBCONTRACTOR Construction Team on the ‘Completed By’ level, with two signatories
on the ‘Accepted by’ level by SUBCONTRACTOR Commissioning Manager and
CONTRACTOR Commissioning Supervisor. For the Non- Commissionable Sub-Systems, MCSSACs shall be completed by SUBCONTRACTOR Construction Team, verified by
SUBCONTRACTOR QC Team and accepted by CONTRACTOR Completion/Operation team.
Upon acceptance of a Sub-System by the Integrated Commissioning Team, the Handover
documentation shall be entered into the CMS database and the Sub-System recognized as
Mechanically Complete.
In general, Sub-System Acceptance Punch Lists shall contain only ‘B’ items and will be kept to an
absolute minimum.
Acceptance of a Sub-System by the Integrated Commissioning Team signifies the formal handover
of ownership of all equipment defined (with exceptions) in the submission.
Following acceptance of a Sub-System by the Integrated Commissioning Team the Pre-com /
Commissioning Permit to Work, LOTO and LUN (Livening Up Notification) systems shall be
applied. Further requirement for access to any of the accepted equipment after this stage will
require the SUBCONTRACTOR Construction / QA/QC teams to have an approved PTW.
8.4
Red-line Drawings
Engineering drawings contained within the accepted MC Handover Dossier which have been redlined to record construction changes to scope at site will be processed through the defined As-Built
Procedure.
8.5
Construction As-Built Drawings
Title: MECHANICAL COMPLETION EXECUTION PLAN
A Construction As-Built Stamp that will be used by Construction team on the latest revision of
drawings. This stamp indicates that the drawing is verified by Construction team and that all
contents inside the drawing are correct to the actual installation. In instances where the drawing
has many pages / sheets and if all drawings are verified as correct then Construction will stamp on
the first page only.
MC WORKFLOW
The Mechanical Completion Flowchart (Appendix 4) demonstrates the flow of activities from
material arrival onsite through to installation, MC-ITR completion leading to the handover process
in the form of MC-DAC and MC-SSAC. Once the MC-SSAC has been accepted the Sub System
is deemed Mechanically Complete and the ownership now lies with SUBCONTRACTOR
Commissioning Team.
9.1
Execution Step
The list of equipment for each discipline will be prepared by SUBCONTRACTOR Commissioning
Team at the early stage of the Construction phase to monitor the completion of all installed
equipment. This will not include Vendor Packaged equipment and Future installation equipment.
Vendor Package equipment with on-site project interfaces should be included as they will generally
require MC-ITRs allocating.
Check sheet Overview will be imported into the Mechanical Completion Database by MC-ITR
Type No, Discipline, System, Sub System and Tag number. The template of MC-ITR forms by
type will be held in the database.
Any changes in the Check sheet Overview of each discipline in the database shall be informed to
Construction team by Commissioning Team via email.
This data will be downloaded from a Computer Hardware Operating system and verified jointly
by SUBCONTRACTOR and CONTRACTOR.
SUBCONTRACTOR shall issue MC-ITRs in Discipline and Sub System packs direct from the
CMS database.
SUBCONTRACTOR shall then proceed to carry out the checks as required by the MC-ITR sheets.
Updating of database status will be carried out and reported on a daily basis.
Upon completion of each MC-ITR Check Sheet and approval by the authorized signatory of all
MC-ITR’s within a Discipline Package the SUBCONTRACTOR will generate a Discipline
Title: MECHANICAL COMPLETION EXECUTION PLAN
Acceptance Certificate (MC-DAC). Prior to submission of the MC-DAC for approval all Punch
list 'A' must be cleared. In general Sub System Acceptance Punch Lists shall contain only ' B'
items. Exceptions can be made with approval from Integrated Commissioning Team (see
Exceptions)
The SUBCONTRACTOR Construction and Integrated Commissioning Team shall carry out a
joint physical review of the offered Sub System at the MC-DAC phase and accept with a jointly
agreed punch list or return the Sub System to SUBCONTRACTOR Construction for completion.
The single discipline DAC where required can commence the Livening Up Notice (LUN) and issue
the Permit To Work for Pre-commissioning activities.
When all MC-DACs are completed within a Sub System a Sub-System Acceptance certificate
(MC-SSAC) will be generated for SUBCONTRACTOR to offer up the Mechanically Complete
Sub-System to the Integrated Commissioning Team for approval. The MC-SSAC will have
attached an MC Status Report and Sub-system Punchlist Report detailing the completed MC-ITRs
and any outstanding punch-list items.
Acceptance of a Sub System by Integrated Commissioning Team signifies the formal handover of
ownership of all equipment defined (with exceptions) in the Submission.
9.2
Ongoing activities post MC
In some instances (particularly relating to Switchboard, Lighting & Small Distribution Boards,
ICSS RIO Cabinets, Marshalling Panels, and Instrument Control Panels) there will be a
requirement to continue with glanding/terminating/testing activities of field cabling after
completion of the MC-ITRs and acceptance of the MC-DAC for that particular Discipline within
a Sub-System.
Although the MC-DAC has been accepted and the equipment now belongs to ICT it will still be
possible for SUBCONTRACTOR Construction to work on this equipment whilst de-energised
with the appropriate Pre-Com / Commissioning PTW.
The ICT will closely monitor this outstanding Construction work in other Sub-systems. At such
times when the majority of the glanding/terminating/testing activities have been completed or
energization of the equipment is schedule driven a joint decision may be made between all parties
to energize the equipment and restrict access to construction.
Title: MECHANICAL COMPLETION EXECUTION PLAN
Energization of the equipment will be processed through the MC-DAC / MC-SSAC / LUN / LOTO
/ PTW Systems resulting in the requirement of a PTW for access to work on the equipment. This
will be coordinated through the PTW/JSA Systems and carefully managed by the PTCS
Commissioning Team and CONTRACTOR Completion System Responsible Engineer(s).
To minimize exposure to working in close proximity to “LIVE” equipment during dayshift
unrestricted access may be granted on a nightshift where the equipment can be safely de-energized
after dayshift activities have been completed and LOTO applied and with the appropriate Pre-Com
/ Commissioning PTW.
9.3
Exceptions to MC-SSAC Handover Acceptance
By exception the Integrated Commissioning Team can agree to accept a Sub-System with ‘A’
Punch List Items if these items can be effectively isolated from the Sub-System on a temporary
basis so as to allow the commencement of Pre-Commissioning in an efficient and safe manner.
Further exceptions can be agreed between SUBCONTRACTOR Construction and Integrated
Commissioning Team for the handover of Discipline packages prior to a Sub-System being
complete to allow Pre-Commissioning to commence on a Discipline basis providing this can be
carried out safely and efficiently. Clearing these exceptions still remains the responsibility of
SUBCONTRACTOR Fabrication and Construction teams as applicable.
9.4
Mechanical Completion Handover Dossiers
Final acceptance of a Sub system will take place upon the submission by SUBCONTRACTOR of
the MC Handover Dossier which shall contain as a minimum:

MC Dossier Completion Status Sheet

MC Sub-system Acceptance Certificate (MC-SSAC)

MC Discipline Acceptance Certificates (MC-DAC's)


deviations or technical clarifications, however in exceptional cases an e-mail signed as accepted
by the relevant discipline Technical Authority and enclosed in the Associated Engineering Queries
section, shall be deemed acceptable for clarification purposes.
9.5
Mechanical Completion Activities
Mechanical Completion will be completed by respective workforces according to each Discipline.
All the inspection and test results are recorded into MC-ITR’s as described in Appendix 09.
PUNCH LIST
On completion of an MC-ITR by SUBCONTRACTOR any item which does not meet the required
standards should be signified by ticking the “P/L” box next to the item on the MC-ITR.
At this point it is important to note that the Punchlist will be a list of items which describes how
and where “completed works” are non-conforming in relation to project specification or scope.
Outstanding / Incomplete works shall not be tracked on the completions Punchlist.
In relation to a “P/L” reference, a ‘Punchlist Raise Form’ will accompany the MC-ITR. The
Punchlist Raise Form contains several categories to identify and isolate Punchlist items within
CMS:

Sub-System (Identifies Sub-System Number that the non-conforming scope is associated with)

Description (Sub-System title)

Punchlist Number (generated automatically from CMS)
Title: MECHANICAL COMPLETION EXECUTION PLAN

Tag Number (Identifies Tag Number that the non-conforming scope is associated with)

Drawing Number (Generally will reference the discipline drawing: Iso, SLD, etc)

Punchlist Description (Written description accurately describing P/L Item)

Category ‘A’ or’ B’ (Indicates the safety implication for operation of the Item)

Materials Required (If material is needed for P/L resolution a PO Number must be input if
available)

Target Completion Date (A forecast date for closing out the P/L will be inserted)

Responsible (Indicates who is responsible for the non-conforming scope, categories stated on
P/L form)
Supporting information may also be referenced and attached with the Punchlist Form to further
clarify non-conforming scope.
Accepted Punchlist details will be entered in the CMS database, which will format individual items
on a discipline basis for each Sub-System (or in any format relevant to the input categories). All
subsequent clearances of Punch List items will be recorded in the database.
a) Outstanding Punchlists compiled by SUBCONTRACTOR and agreed by the Integrated
Commissioning Team will be submitted with the completed MC-DAC in discipline format,
and will be agreed and categorised by SUBCONTRACTOR and CONTRACTOR
Completions Team before being issued and recorded in the consolidated Punchlist database.
b) All punchlist items of both ‘A’ and ‘B’ categories are to coincide with the relevant discipline
tag number where the “P/L” reference has been used.
c) Items will also be supported by relevant paperwork; order numbers, damage reports, material
shortage reports, photographs, etc.
d) Any item considered to be a design change will be raised in the form of a design change
proposal with supporting information, follow Project Management Change Procedure.
e) Punchlists items will always be correctly categorised into ‘A’ or ‘B’ status
Title: MECHANICAL COMPLETION EXECUTION PLAN
Figure 5: MC Punchlist Flowchart
Title: MECHANICAL COMPLETION EXECUTION PLAN
Category ‘A’ Punchlists
Any punchlist item that is categorised as 'A' will indicate that the relevant Sub-System is
considered unsafe to operate or cannot be operated effectively. It will be rejected and returned in
its entirety to SUBCONTRACTOR Construction / Quality Control / MC Team as applicable. The
returned Sub-System shall be accompanied by the MC-DAC & MC-SSAC which will be noted,
rejected, signed and dated. Cat A P/L items should be identified at the MC-DAC phase and unless
agreed and accepted by all parties as being acceptable the S/S should not reach the MC-SSAC
stage. Any Safety Critical or Operation Critical items that must be repaired or corrected before the
equipment can be safely Pre-Commissioned, Commissioned or Operated. Such items may include
but not be limited to missing valve / instruments, faulty equipment, leaks that could cause damage
to plant, personnel and the environment.
The MC-DAC and MC-SSAC will be re-submitted by SUBCONTRACTORConstruction / Quality
Control / MC Team on completion/resolution of punchlist ‘A’ items.
As previously described in special circumstances Integrated Commissioning Team will sanction
handover of Sub-Systems with ‘A’ Punchlist items included, Typically this would be where a P/L
item can be rendered safe and is not critical to the progress of Pre-Commissioning /
Commissioning. Prior to acceptance of such Sub-Systems a thorough review of all safety aspects
relating to operation of the equipment will be carried out between all relevant parties.
Category ‘B’ Punchlists
Any items that can be repaired completed or corrected at a later date and which will allow the
commencement of Pre-Commissioning/Commissioning activities without endangering personnel,
plant, environment or operational integrity. Such items may include but not be limited to missing
valve handles, missing identification tags or plates, broken gauge glass, paint touch-up.
The raising of such items for acceptance should be kept to an absolute minimum as a high number
of such P/L items may result in a rejection of the MC-DAC and/or MC-SSAC.
Punchlist Clearance
CMS will produce punchlist line item reports by Sub-System, Discipline and Tag Number. In order
to clear a punchlist line item(s) a Punchlist Clearance report shall be printed and marked up.
As a punch item is cleared in the field the appropriate sections against the punchlist line item on
the report table will be wet signature signed and dated.
Title: MECHANICAL COMPLETION EXECUTION PLAN
At this point the CMS Operator will update the status of punch item(s) into CMS based on the
information from the report table.
PRESERVATION
Preservation and De-Preservation throughout the Mechanical Completion phases shall be the
responsibility of SUBCONTRACTOR Construction / Quality Control / MC Team /
Commissioning Team and will be carried out in accordance with approved preservation procedures
and Vendor recommended preservation requirements.
EX INSPECTION
Every piece of Ex Equipment, either Vendor or SUBCONTRACTOR installed, is required to have
a detailed Ex inspection carried out. All tagged Ex equipment should be uploaded into CMS and
allocated an MC-E30-A for completion during the early Vendor works scope or at site during the
Mechanical Completion Phase of the Project. In addition to being entered into CMS every Ex tag
needs to be included in the Project Master Ex Register. Ex Leader is responsible for managing /
updating and issuing the Project Master Ex Register.”
VENDOR MANAGEMENT RELATED MC WORK
SUBCONTRACTOR Commissioning Manager shall be responsible for the coordination and final
approval of all Construction and Commissioning Vendor site visits.
Any Vendor onsite requirements during the Fabrication / Construction / Integration phases will be
identified and coordinated by SUBCONTRACTOR Construction Team.
The initial issue of SUBCONTRACTOR Construction schedules shall be reviewed and where
possible rationalized and coordinated to avoid duplication of effort or resources.
SAFETY MANAGEMENT RELATED MC WORK & PERMIT TO WORK
The safety objective during the execution of Construction and Mechanical Completion activities
is to prevent unsafe actions and working conditions which may cause injuries, health risks and
damage to property.
All personnel involved shall comply with Project Safety Health and Working Environment
requirements and also safety requirements contained in Site Manuals and procedures.
SUBCONTRACTOR shall implement a Permit to Work System which shall remain in force
throughout onshore Mechanical Completion.
Title: MECHANICAL COMPLETION EXECUTION PLAN
The CONTRACTOR Permit to Work system shall be implemented after systems handover to
CONTRACTOR operations.
PLANNING AND MONITORING SYSTEM
15.1
Planning system
Planning of Mechanical Completion shall be driven by Commissioning Sequences which
determines the precedence of priority for each System. Utility Systems such as Diesel, Instrument
Air, Drains and Electrical Power are required to provide services for all other Platform Systems
and therefore shall be prioritized for Mechanical Completion.
Approved dates for Mechanical Completion of each Sub-System shall be loaded into CMS.
CONTRACTOR may elect to implement Mechanical Completion Milestones ahead of baseline
schedule in order to progress critical commissioning activities early. Mechanical Completion SubSystem Milestones shall be determined by:

Site testing required following Factory Acceptance Testing.

Equipment Delivery dates.

Planned duration of SUBCONTRACTORConstruction and MC activities.

Definition of work scope.

Required MC Handover dates to meet critical start dates of Pre-Commissioning and Dynamic
System Commissioning in order to achieve overall Project Completion Milestones.
15.2
Progress Measurement
The Mechanical Completion progress will be measured on the completion of the MC-ITRs and
will be submitted by the Construction Team to the MC Team for uploading into CMS.
The SUBCONTRACTOR Completions Management System (CMS) is capable of tracking and
reporting progress of MC-ITR completion by Tag, Discipline, Sub System and System. These
reports will be compiled by the CMS Coordinator as and when required by Project Management
in both native format and pdf. The level of detail can be selected by using simple drop down boxes
within CMS to give the required information. Such “Live” CMS data can be passed from the CMS
Coordinator to the Project planning department for uploading into Primavera.
As a follow on from tracking and reporting the MC-ITR completion status CMS can track and
report against Handover Documentation such as MC-DAC and MC-SSAC completion in the same
way as for ITR completion. CMS will track completion of agreed MC Handover dates by Sub
Title: MECHANICAL COMPLETION EXECUTION PLAN
System / System to meet critical start dates of Pre-commissioning and Dynamic System
Commissioning.
15.3
Monitoring and report
Mechanical Completion Progress measurement system will be updated on a weekly report on MCITRs progress and percentage completion. The reporting cut-off will be COB Friday each week.
The progress figures are included in the weekly progress report which will be submitted to
CONTRACTOR on Tuesday of the following week.
QUALITY ASSURANCE AND CERTIFICATION INTERFACES
The Project MC and Commissioning groups interact with the QA/QC group in many ways,
primary interaction is through the preparation, issuance and implementation of the project
procedures. The quality assurance group shall also conduct periodic internal audits to ensure that
the MC and Commissioning groups are functioning in line with the procedures and guidelines that
have been developed specifically for the Project.
It is the responsibility of the quality group to ensure the requirements for ‘CERTIFICATION
AUTHORITY’ certification are identified and provided for throughout the design, procurement,
equipment manufacturing, construction, integration, commissioning and start up phases of the
project. For Mechanical Completion and Commissioning phases the certification requirements
will primarily be the inspection of completions certification and witnessing of specific testing
activities by ‘CERTIFICATION AUTHORITY’ which will be coordinated by the Quality Group.
SUBCONTRACTOR shall be responsible for the accuracy and integrity of the CMS database and
MC implementation including physical records of MC Inspection Test Records (MC-ITRs) with
built in quality control activities to verify the achieved quality standard throughout the MC phase.
SUBCONTRACTOR will be responsible for ensuring the accuracy and integrity of the CMS
database including physical records of MC and PC Inspection Test Records (MC-ITRs & PCITRs), status indices and project certification used in the handover between the responsible parties
in each phase.
The SUBCONTRACTOR Coordinator shall be responsible for ensuring:

Tests and checks carried out are executed, witnessed as required and recorded in accordance
with this procedure.
Title: MECHANICAL COMPLETION EXECUTION PLAN

Validation of MC status and acceptance certification when Discipline packages and Subsystems have been mechanically completed.

Accuracy of Punch list records to include all deviations errors or incomplete work within the
sub system that cannot be rectified prior to acceptance
Quality assurance of site test equipment
SUBCONTRACTOR shall maintain a comprehensive list of all test equipment to be used. This list
shall prove that all test equipment has a standard of accuracy equal to, or better than, that of the
manufacturer's stated accuracy for the instrument / equipment being tested.
Acceptable evidence of satisfactory condition of test equipment (e.g. copies of up to date Test
Certification) shall be provided in accordance with the SUBCONTRACTOR approved calibration
procedure.
All test equipment shall be frequently checked throughout the MC period for deterioration. Where
test equipment requires an electrical or air supply, SUBCONTRACTOR shall ensure accuracy of
voltage and frequency / pressure and quality.
