Risk Management.
5.0
The process of assessing these risks and implementing risk-reduction measures appropriate to the
risk level, in a way that applies resources to address the risks on a priority basis.
Procedure:
5.1 SIMOPS Definition
SIMOPS is the performance of potentially conflicting activities at the same time, in the same or
adjacent location. All tasks may be done safely, but without coordination, one act could have a
dangerous consequence to another.
For example:
• Production / Construction (fabrication and erection operations).
• Hot work being carried out in association with other hazardous work, such as the
proximity between several potential sources of flammable materials / substances
and activities having potential ignition sources.
• The coexistence of people who might be unaware of the risks inherent to
activities they are not familiar with.
The risk of physical interference such as heavy lifting, barges, anchorage, transportation, material
handling etc. i.e. interference between construction / fabrication operations
5.2 SIMOPs Organization and Management:
SIMOPs procedure shall be followed, when two or more than two activities e.g Confined space
entry, welding, gas cutting, grinding, crane operation, painting, working at height,

lifting, lowering, radiography, commissioning, etc. are being undertaken at the same place
& time or in the same vicinity.
During SIMOPs, all the hazards related to both the activities shall be identified and Risk
assessment shall be carried out for the combined activity, then appropriate control measures
needs to be defined. Person In-Charge (PIC) shall be nominated by Project Manager/Yard
Head who is competent to manage the SIMOPs risk.
Prior to carry out any SIMOPs, a meeting of the departments involved and HSE representative
should be held to agree and confirm the program and preparatory activities.
Prior to undertaking SIMOPS, job study as well as site specific risk assessment should be arranged
by the PIC for SIMOPS with all agencies (department/Contractors) associated with SIMOPS, to
ensure that all the hazards related to the proposed operations/activities are identified,
assessed and determined to have the risk as low as reasonably practicable (ALARP). The SIMOPs
shall be carried out as per the planned procedure with all the controls determined.
5.3 SIMOPS Identification:
While carrying out any activity if it is observed that any other activity is being done parallel
then immediately SIMPOs matrix shall be referred to check the compatibility of the activities.
Accordingly decision shall be made to continue the job or not. The conditions for carrying out such
activities as mentioned in the SIMOPs matrix shall be followed.
Line Management and HSE representative shall be present at the SIMOPs site and monitor
the activities before the start up, during execution.

Once the scope of work have been completed, the work specific plan shall be developed, using all
of the information from each participant’s involvement in order for a systematic assessment of
the SIMOPS to be carried out.
Line Management shall prepare individual plan, which include the following information:
• Organization chart with role and responsibilities
• Main hazards associated with the work and established risk mitigation strategies
with an accompanying risk register.
• A step by step procedure of the work to be done with the agreed mitigation measures.
• What human resources are to be used and how
• Equipment and machinery to be used
Schedule of work
• Communications methodology to be used during the SIMOPS
• Contingency plans to safely cease work during the SIMOPS if the possibility of
danger is identified or the SIMOPS is threatened by unexpected occurrences.
• Escape routes in the event of emergency.
• Emergency response plan and resources.
5.6 SIMOPS Matrix
The SIMOPS categories are identified in a matrix, please refer L&T HEIC - MRU SIMOPS Matrix
The matrix is a planning aid to avoid conflict in simultaneous operations as far as practicable.
Categorization of SIMOPS Matrix
SIMOPS matrix helps us to take decision in the situation of SIMOPS as follows:• Yes -‘Y’ means, SIMOPS can proceed safely without additional control measures.
• Not permitted - ‘X’ means SIMOPS cannot proceed. One or more of the activities to be
Suspended / deferred.
• Control Measures required - ‘C’ means SIMOPS may proceed with additional control
measures.
Not Applicable- ‘NA’ means SIMOPS is not applicable
5.7 SIMOPS Assessment
Risk Management is to cover the concurrent activities that would result in hazardous situations.
The exercise is to be supported by a work specific Risk matrix. This matrix will help in
identifying the hazards that are acceptable, not acceptable or those that are acceptable
with room however for further mitigation (enhancement by lowering the risk).

A Risk matrix might demonstrate that the hazard has a low ‘Frequency’ of occurrence
and/or a negligible Severity of impact. This situation would not warrant further actions to
be taken as the hazard category would be in the ALARP Region.
If there is a direct impact on neighbouring area an additional risk assessment (HIRA) shall be
prepared by the team by consider the effects of the other SIMOPs activities.
At this point in the assessment, the SIMOPS Team may well be satisfied and accept the
situation without any further action to be taken. Otherwise, the team may so wish to address
lowering the hazard’s ALARP to a more reliable and safer situation.
RISK Management is achieved as follows:
• Identify existing Safety Controls.
• Recommend staggering of the hazardous simultaneous activities if no Safety Controls
are identified;
• Recommend provision of Safety Controls if Staggering is not acceptable or possible. If
Safety Controls are not available, it is prudent to have at least two or three barriers in
place for each of the identified risks.

Hierarchy of Controls
All key participants involved in the SIMOPS shall establish a hierarchy of controls for each of their
specific SIMOPS activities, as well as for the overall controls of the SIMOPS. These controls shall
cover adequate lines of reporting during the SIMOPS and be effective during both normal and
emergency situations and during each phase of the activity.
Review Assessment
All key participants involved in the SIMOPS shall hold a review of collectively identified risks
associated with the SIMOPS and agree the overall mitigation measures to be employed before the
SIMOPS is given the go-ahead. Mitigation measures will be formulated using the HIRA
methodology in association with the known conflicts connected with each participant’s scope of
work.
Controls agreed shall address individual hazards and be used in the following order of
effectiveness, as appropriate:
• Eliminate the hazards.
• Reduce the risks to an acceptable level.
• Proper signage & barricades must be setup in the workplace identifying that SIMOPS are
being conducted.
• Use PPE.
5.8 SIMOPS Interface Documentation
SIMOPS Interface document(s) shall be prepared for the SIMOPS activity. The documentation shall
clearly identify all SIMOPS activities, applicable to all participants’ respective operations and
contain the following information:
• A SIMOPS Matrix to determine which activities are permissible simultaneously
• A validation exercise to be conducted alongside the original SIMOPS assessment to ensure
that all mitigation measures remain current and valid.
• The purpose and scope of the SIMOPS, with definitions
• Person in overall charge (PIC) of the SIMOPS, reporting lines and roles and responsibilities.
• Scope of work to be covered by the various documents in the SIMOPS (e.g. daily log sheet,
