General terms for every loading and
discharge
This document states the general and particular REPSOL companies’ requirements to
perform a thorough quality and quantity cargo inspections appointed by Repsol Trading.
As and when Repsol appoints an independent inspection company to attend a loading, a discharge or a
tank/ pipeline transfer then Repsol envisages the inspector playing a central role in the quantity and
quality control process of the operation. We expect inspectors to:
A. Provide, attest to or endorse the certification of quality and quantity of the product loaded, discharged
or transferred.
B. Identify anomalies, discrepancies or non‐compliance in operational procedures and relevant quality
specification and draw
attention to such matters not only in the inspection report but also by the issue of formal letters of
protest as and where
necessary. Such anomalies/discrepancies shall also be immediately reported verbally to the relevant
Repsol personnel.
C. Ensure that the adopted methods of measurement, sampling and testing are in accordance with both
accepted standards and
specific requirements as and where identified by Repsol.
D. They shall also draw attention to matters which may be relevant to protect interests of Repsol and
other clients involved.
E. Therefore as an aide to achieving the above, Repsol has produced the following instructions as
requirements to be followed for the inspection of those cargoes which are responsibility of Repsol.
F. Inspectors shall render the service according to the instructions stated in the General instructions for
Quality and Quantity Inspections of Crude Oil and Petroleum Products. In case of non‐ compliance, this
event will be considered as a contractual breach. Each and every one of the independent inspection
companies – including all of its employees, whether internal or external – should comply with Repsol´s
ethical values (integrity, responsibility, transparency, flexibility and innovation) and principles (loyalty,
integrity, bona fide, legal and ethical criteria), both while rendering all relevant services for Repsol, and
during the exercise of the professional activity for other parties.

2. GENERAL GUIDELINES
Inspector will advise if last three cargoes of the vessel are compatible with the cargo
and/or could affect the quality of the product to be loaded and recommend washing procedure if
required. Depending on the previous cargo, the Inspector should consider the option to draw and run a
first foot sample. Please refer to annex A.
Final quantity shall be reported as soon as available in:
KGS/ MT (air/vacuum) / Lts. @15°C / BBL @60°F / GAL @ 60°F indicating the table used for
calculation.
Quantity certificates must include ship’s figures and shore tank ullages before and after
the loading and discharge operations. Ship’s ullage report to show the remaining on board quantity
(R.O.B.) after discharging or the on board quantity (O.B.Q.) prior to loading, and the observed
temperature of crude oil or product.
2.1 QUANTITY DETERMINATION
Before commencing the loading or discharge operations the Inspector
 Must verify that the shore line is full, and it must be measured, if necessary, according to API MPMS
Chapter 17.6.
Must verify that the product in the line is compatible with the cargo.
Perform a line displacement control following the API MPMS Chapter 17.6, if necessary.
Repsol Trading shall be informed accordingly on commencement the loading/discharge operation.
The Inspector shall advise whether the tanks are static or dynamic. If the cargo is
loaded from more than one shore tank, the number of tanks and the quantities delivered from each one
is to be included in the inspection report. When the quantity is to be determined in the shore tanks and
these are dynamic, the Inspector shall inform all the parties advising that the quantity shall be based on
vessel´s figures corrected by a valid loading Vessel Experience Factor (VEF).
Whenever simultaneous deballasting must be performed during loading operations, the
inspector must request the reason from the vessel’s representative and record it in the inspection
report. Then a Letter of Protest must be issued.
If in the key meeting or other stage, the quantity agreed to be loaded is different from our nomination,
the situation will be urgently informed to REPSOL TRADING by telephone and by writing.
If the vessel or the terminal stops loading before the quantity ordered is achieved, the inspector must
note protest and send a copy to each party separately by email. The report must clearly state if the
loading was stopped by the terminal or the vessel. Any anomaly, discrepancy or incident must be
immediately reported.
Inspector is requested to issue a Letter of Protest addressed to the vessel and/or terminal if the
difference between the quantities measured at shore tanks and vessel tanks (corrected by a valid
loading VEF) exceed over 0.25%, then issue a technical report indicating the origin or causes for these
figures.

2.1.1. On Board Vessel
All measurements and samples activities to be performed on board a vessel in
accordance with API procedure. All gauges shall be witnessed by inspector and performed by the
vessel´s staff and/or by the terminal personnel, should electronic devices are used by ship’s crew,
advise manufacturer and model. Water cuts are to be taken (where applicable) and reference heights
recorded. Temperatures are to be taken on individual tank basis at least at upper, middle and lower
levels.
It is the responsibility of the inspection company to ensure that sufficient inspectors are
in attendance to avoid unnecessary delays. Prior to loading, inspector must ascertain and record nature
of at the previous three cargoes on board and satisfy themselves that the tank, pump and line cleaning
procedures carried out are suitable for the product(s) to be loaded. Where tanks are not considered
suitable, the appointing reference should be notified and loading shall only proceed after receipt of
written responsibility for loaded quality from the ship´s Master, the appointing reference or some other
relevant and responsible party. On completion of discharge the inspector shall be satisfied that the
vessel´s tanks and lines are well drained.
Inspector must report and record the quantity of any free water found in vessel´s cargo
tanks. Where free water quantities represents 0.25% or more of the total cargo, Repsol Trading shall be
notified. ROB surveys shall be conducted by hand tape (where possible) from ullage points and/or
sounding points. With high pour cargos, soundings are to be taken throughout the vessel´s tank(s) to
determine if any ROB lies in a wedge formation. Where ROB is present, gauges must be clearly noted
and wedge formula applied where applicable. The nature of the ROB must be noted and inform if the
ROB is liquid/non liquid, pumpable/non pumpable.
Measure and record quantity of any ballast and slops on board before and after any
loading or discharging operations. The Inspector is required to report any free water found during the
gauging operation. If any free water is found a LOP must be issued. Undesignated spaces shall be
inspected for cargo leakage, i.e cofferdams, pump room, bilges, forepeak and segregated ballast
spaces, double bottoms and duct keels. Sea chests and overboard discharges are to be checked and
seal numbers recorded. If the cargo is compatible, a full bunker survey shall be performed on arrival
and before departure. Bunker samples must be taken and retained for 90 days.
Immediately prior to taking cargo measurements, read and record vessel´s draft, trim
and list. Draft, list and any resulting ullage corrections should be noted on the ullage report .
When the official figures are calculated on the vessel figures with loading VEF applied,
the quantity certificate shall include the ullage report and the loading VEF study. These reports shall be
approved and accepted by all parties.

2.1.2. Terminal
All shore tank gauging shall be carried out in full in accordance with API chapter 17.1
and 17.2 guidelines for Marine Cargo Inspection. Designated shore tanks must be manually gauged.
Condition of the shore lines prior to discharge has to be ascertained if applicable. A line displacement
must be performed; inspection is to ascertain whether a line displacement has been effected. Details of
either must be noted in the report. If line verification cannot be performed, protest has to be noted.
The condition of floating roofs must be noted and corrections applied where necessary. If floating roofs
are within 12 inches of the critical zone during gauging, then a protest should be delivered to the
terminal representative.
If auto‐samplers are used, the inside of the container must be checked to ensure
cleanliness and a note of the settings must be made. In the event that the outturn quantity is based on
shore tank measurements, then all receiving shore tanks shall be static and shall have a liquid oil
surface at the official point of calibration; should shore tanks be dynamic, then a letter of protest shall be
filled against the terminal representative. Additionally, all receiving shore tanks shall contain sufficient
oil, prior to receipt, to ensure that the floating roofs are afloat and clear of the “critical zone” by a
minimum of twelve inches. All receiving shore tanks shall be calibrated for critical measurement as set
forth by API 2.2 ASTM designation 1220.
All measurements, for both ship and shore, shall conform to API manuals, always
allowing for local regulations and safety restrictions. Manual measurements, including ullages and /or
innages, temperatures, water cuts and reference gauge heights are to be taken and recorded by the
inspector and witnessed by vessel’s staff and/or terminal personnel. In the event that the inspector can
only witness manual measurements, then every endeavor should be made to verify the accuracy of the
equipment being used Manual measurements of shore tanks should be undertaken as close as
possible, preferably within two hours, of the start and finish measurements and checked just prior to the
start of transfer and just after the end of transfer to ensure that the shore tank liquid level has not
appreciably change during the interval between manual gauges and when the shore tank was opened
and closed. If automatic gauges are used for custody transfer measurement, the aggregate difference
between manual and auto gauges should be less than 4mm.
2.1.3. Line displacement
In the event that the outturn quantity is to be based on shore tank measurements, or if
meters are to be used, the Inspector shall monitor the performance of the line displacement. The line
displacement is to be carried out in accordance with API chapter, as necessary.
In accordance with API chapter 17.6.10.1.4, the volume tolerance for the line displacement will be
derived from the “precision of measurement” indicated in chapter 17.6.11, that is, 1/8 inch (3 mm).
© Repsol Trading. December 2015.
10
Therefore, the accepted tolerance for a line displacement shall be the total of the
volume equating to 1/4 inch in the receiving shore tank calibrations, plus the volume equating to 1/4
inch in the delivering vessel tank calibrations. This tolerance represents the measurement precision
limit (1/8 inch) for the opening and closing gauges for both the receiving shore tank and the delivering
vessel tank.
If, during such line displacement, the difference between the volume that the shore tank
receives and the volume that the vessel delivers is within the accepted tolerance stated above, or if the
volume that the shore tank receives is in excess of the volume that the vessel delivers by an amount
either within or in excess of the accepted tolerance stated above, then the shore line is to be considered
full. If, during such line displacement, the volume that the shore tank receives is less than the volume
that the vessel delivers by an amount greater than the accepted tolerance stated above, then the line
shall be considered slack. In cases when the line is found to be slack, the entire difference between the
volume that the shore tank receives and the volume that the vessel delivers shall be credited to the final
outturn volume. It is preferable that the shoreline is internally displaced in the inspector’s presence
within two hours of the commencement of loading. Should the terminal refuse a line displacement then
another suitable line fullness check should be carried out to the satisfaction of the inspector.
2.1.4 On completion of an operation the inspector shall:
Compare, reconcile and record all the relevant shore tankage, BOL, and ships figures
(gross and net), obtained by calculation. Initiate an investigation if the percentage difference in any
reconciliation exceeds 0.25% volume after application of VEF and issue a Letter of Protest addressed
to the vessel and/or terminal, then issue a technical report indicating the origin or causes for these
figures differences and report any instance where measurements are taken under conditions that are
not conducive to accuracy or could not be taken.
In order to minimize delay to vessels, finalize and present in person to designated terminal personnel
and vessel´s Master or Chief Officer all the relevant final (or provisional) figures and calculation of
quantity within two hours after hoses have been disconnected. Where agreement is not possible, the
Inspector´s figures shall be used and the background detailed in the final report.
Quantity certificates must include ship’s figures and shore tank ullages before and after
the loading and discharge operations. Ship’s ullage report to show the remaining on board quantity
(R.O.B.) after discharge or the on board quantity (O.B.Q.) prior to loading, and the observed
temperature of crude oil or product. Also Inspector´s findings and explanation of anomalies.

2.2 QUALITY DETERMINATION
The cargo must comply with the specs and the methods in accordance with Repsol
Trading nomination. Where an Inspection Company is appointed to verify and certify the quality of the
product, the Inspector shall on appointment :
2.2.1. Load Operations
a) Contact the relevant refinery personnel in order to confirm the tankage to be tested and make the
necessary arrangements for sampling.
b) The inspector will certify that all analyses have been performed according to the correct method
and/or procedure and that all laboratory equipment is correctly calibrated.
c) Analysis may be carried out in the refinery laboratory and witnessed by the inspector, or in the
inspection company´s own laboratory, or in a third party laboratory. Approval from the appointing
reference is required before samples are submitted to a third party laboratory for analysis. Where more
than one laboratory has been used for testing, the certificate of quality shall clearly show the laboratory
that is responsible for each analytical test.
d) If any tests cannot be performed at the refinery laboratory, inspectors shall advise when, where and
the cost (if it is not included in our agreed fee) of the analysis at the time of confirmation of our
appointment for clearance.
e) The inspector will keep REPSOL TRADING informed about the following points:
• If the inspector has been allowed or not to witness all the analysis done or just some of them.
• Where the analysis have been performed.
• When such analysis have been performed.
• If the inspector has been allowed to witness the shore line displacement.
• Any other findings that could be of detriment to the quality of the product.
f) Unless agreed to the contrary, under no circumstances shall a vessel be allowed to load or to sail
without product quality being verified as meeting the required specification.
g) Any further analysis requested by any other party from shore / sphere’s samples (when binding
quality is shore spheres) or ship tanks samples (when binding quality is ship tanks) performed at the
refinery’s laboratory or at any other laboratory, has to be communicated by the inspector to REPSOL
TRADING operations department for clearance.
h) If possible provide Repsol Trading with any quality test performed on shore tanks before loading,
even if the binding quality is to be determined on ship tank.
i) When binding quality is determined on shore tanks, loading will only commence if the quality of the
product complies with Repsol Trading specifications shown on their nomination. It is Inspector´s
responsibility to make sure that this requirement is accomplished, and alert if it is not before loading
commences.

2.2.2 Discharge operations
Upon vessel arrival, the inspector must collect the necessary samples to verify that the
quality of the product complies with the quality loaded/nominated.
The inspector shall supply the quality results for the product on ship’s tanks to the operational contact
as soon as they become available, and always prior to the commencement of discharge.
The Inspector must verify that the quality of the product complies with the specification advised before
discharging. Whenever Repsol is the Receiver and the binding quality is determined at ship´s tanks
before discharging, discharge will only commence if the quality meets each specification, and shore
tanks and lines cleanliness must be approved prior to discharge. It is the Inspector´s responsibility to
make sure that this requirement is accomplished and alert if it is not.
All measurements, for both ship and shore, shall conform to API manuals, always allowing for local
regulations and safety restrictions.
Manual measurements, including ullages and /or innages, temperatures, water cuts
and reference gauge heights are to be taken and recorded by the inspector and witnessed by vessel’s
staff and/or terminal personnel. In the event that the inspector can only witness manual measurements,
then every endeavor should be made to verify the accuracy of the equipment being used Manual
measurements of shore tanks should be undertaken as close as possible, preferably within two hours,
of the start and finish measurements and checked just prior to the start of transfer and just after the end
of transfer to ensure that the shore tank liquid level has not appreciably change during the interval
between manual gauges and when the shore tank was opened and closed. If automatic gauges are
used for custody transfer measurement, the aggregate difference between manual and automatic
gauges should be less than 4mm. It is preferable that the shoreline is internally displaced in the
inspector’s presence within two hours of the commencement of loading. Should the terminal refuse a
line displacement then another suitable line fullness check should be carried out to the satisfaction of
the inspector.
2.3 SAMPLES
The inspector is responsible for ensuring that representative samples are drawn at all
appropriate stages, placed on board at the loading port and collected and delivered to terminal/receiver
against receipt. New, clean containers of unquestionable integrity must be used. Avoid pouring samples
from one container to another, where possible. All samples of high RVP materials are to be drawn on
individual tank basis, sealed and transported to the laboratory in ice as expeditiously as possible.
Composites are to be made up only after RVP determination has been completed.
If such samples are not available for collection at the discharge port, a protest in writing shall be issued
to the Master who shall be invited to confirm in writing if no samples were placed on board at the
loading port.

13
The inspector must draw more samples or proceed to other analysis on the spot, or in
the laboratory, whenever he thinks it is necessary and when it may prevent quality problems in the
product; in the same way, he must take the necessary operational actions in order to prevent
delays or shortages and advice REPSOL TRADING in advance.
Samples shall be kept labelled, sealed and signed by all the parties involved in the
operation. They must be retained as witness samples for 90 days in appropriate conditions, except for
LPG and petrochemical samples, which must be retained at least for time enough to discharge the
cargo at receiver’s installation and analyze the product after discharge.
A sample report must be issued, clearly stating the samples taken (shore, line & ship’s
samples) and the seal & label numbers of each sample. The samples must be sealed and delivered to
the attention of:
o The Vessel’s Master
o The Shipper
o The Vessel for receivers.
Inspector must retain sufficient sealed shore tanks samples, individual ship tanks
samples and composite samples after loading. Inform immediately REPSOL TRADING if sampling
procedure cannot be strictly followed for any reason.
2.3.1. Samples to be retained by inspector
The inspector is responsible to retain designated samples in their own installations and
under their responsibility. All samples should be identified at least with the following information:
Place where sample has been taken.
When the sample has been taken (previous, during or after) operations.
Explanation of sample
Date and time of sample
Sample number
All samples shall be retained at least for 90 days, except for LPG and Petrochemical, as it is specified
below in their appropriate sections.

2.3.2. Sample container type
Some general recommendations regarding containers are:
‐ Plastic bottles should not be used for storage of gasoline or gasoline component samples.
‐ Pre‐used containers are permitted, following appropriate cleaning, only for petrochemical products,
LPG and other gases but are not recommended for custody transfer samples.
‐ Steel cans (tin plate) are not recommended for long‐term storage due to concerns regarding
corrosion.
‐ Cork closures are not recommended.
‐ Closures should be airtight (polyclone or screw cap with inert insert‐ PTFE is preferred).
‐ Synthetic rubber seals are not recommended for samples used for sulfur testing.
2.4 TIME REPORT
The inspector is required to ensure that the time report clearly evidences time and date
of completion of the vessel operations, disconnection of hoses, any causes of delay in
berthing/loading/discharge (berth occupancy, bad weather conditions, changes in line‐up for berthing,
etc.) as well as record weather conditions during loading / discharge, such time report shall be duly
signed by attending parties.
2.5 LETTERS OF PROTEST
Letters of protest must be as simple as possible, but must state clearly any
quantity/quality/timings discrepancies. All Letters of Protest must be correctly addressed and duly
signed by the receiving party. Should the receiving party refuses to sign this letter, then the inspection
shall state this fact in writing.

15ºC, kilos, Metric Tons (Air /Vac), US barrels, US gallons, Long tons (Air / Vac).
If the shore tanks have floating roofs it is important to verify that the roofs were not in
the critical zone at the start or finish of the movement. Measurements taken in the critical zone are not
acceptable for custody transfer (refer API MPMS Ch. 3). Sediment build up can change the critical
zone. Tank capacity tables should show the levels at which the roof is fully grounded or floating Verify
that any changes in these levels have been recorded. Verify that correct strapping tables were used to
obtain volumes.

6. LIGHT, BIOFUELS AND HEAVY PRODUCTS DISCHARGE
6.1 Quantity
The quantity of cargo discharged must be determined as per terminal Standard procedure
at the discharge terminal. Please advise on terminal standard procedure for quantity measurements.
Quantity determination shall be made using meters or by measuring the shore tanks to which delivery is
made. Please also take the measurement by ullaging ship’s cargo tanks indicating if valid loading VEF has
been used. These values are to be expressed according to the “Gross” and the “Net” sample, expressed
in Liters at 15ºC, kilos, Metric Tons (Air / Vac), US barrels, US gallons, Long tons.
The inspector must ask for static tanks to discharge the product; if it is not possible, it
must be stated in the report. If the difference between the bill of lading quantity and the outturn quantity
exceeds 0.25/, the inspector must send REPSOL TRADING a voyage analysis report and a verbal advise.
In the event that the outturn quantity is to be based on shore tank measurements, or if meters are to be
used, the Inspector shall monitor the performance of the line displacement. The line displacement if to be
carried out in accordance with API chapter, as necessary.
In accordance with API chapter 17.6.10.1.4, the volume tolerance for the line
displacement will be derived from the “precision of measurement” indicated in chapter 17.6.11, that is, 1/8
inch (3 mm). Therefore, the accepted tolerance for a line displacement shall be the total of the volume
equating to 1/4 inch in the receiving shore tank calibrations, plus the volume equating to 1/4 inch in the
delivering vessel tank calibrations. This tolerance represents the measurement precision limit (1/8 inch)
for the opening and closing gauges for both the receiving shore tank and the delivering vessel tank and
the delivering vessel tank.
If, during such line displacement, the difference between the volume that the shore tank
receives and the volume that the vessel delivers is within the accepted tolerance stated above, or if the
volume that the shore tank receives is in excess of the volume that the vessel delivers by an amount
either within or in excess of the accepted tolerance stated above, then the shore line is to be considered
full. If, during such line displacement, the volume that the shore tank receives is less than the volume that
the vessel delivers by an amount greater than the accepted tolerance stated above, then the line shall be
considered slack. In cases when the line is found to be slack, the entire difference between the volume
that the shore tank receives and the volume that the vessel delivers shall be credited to the final outturn
volume.
‐ All measurements, for both ship and shore, shall conform to API manuals, always allowing for local
regulations and safety restrictions.
‐ Manual measurements including ullages and/or innages, temperatures, water cuts and reference gauge
heights are to be taken and recorded by the inspector and witnessesd by vessel´s staff and/or terminal
personnel. In the event that the inspector can only witnessed manual measurements then every endeavor
should be made to verify the accuracy of the equipment being used.

‐ Manual measurements of shore tanks should be undertaken as close as possible, preferably within two
hours, of the start and finish of the transfer into each shore tank.. In any event the shore tank automatic
gauges are to be noted at the time of manual measurements and checked just prior to the start of transfer
and just after the end of transfer to ensure that the shore tank liquid level has not appreciably change
during the interval between manual gauges and when the shore tank was opened and closed. If automatic
gauges are used for custody transfer measurement, the aggregate difference between manual and auto
gauges should be less than 4mm.
‐ It is preferable that the shoreline is internally displaced in the inspector´s presence within two hours of
the commencement of loading. Should the terminal refuse a line displacement then another suitable line
fullness check should be carried out to the satisfaction of the inspector.

‐ It is preferable that the shoreline is internally displaced in the inspector´s presence within two hours of
the commencement of loading.
Should the terminal refuse a line displacement then another suitable line fullness check should be carried
out to the satisfaction of the inspector.

8.3 Samples
After discharging
‐ The inspector shall send immediately a full report including the following details:
Ship´s figures ( MT(VAC/AIR), LTS A 15º DEG C, BBLS, USG), gross and net.
Quality report evidencing methods used.
Time sheet evidencing the date of completion of vessel discharge and the causes of any delay.
Outturn quantity as soon as available.
 Comparison between quantities as per B.L´s, vessel´s figures, discharge port shore tank quantities
and in transit variation.
Inspector´s findings and explanation of anomalies.
The inspector will ask the master, on behalf of REPSOL TRADING, for the samples placed on board at
the port of origin, and deliver them to the refinery against refinery’s staff receipt for being retained there
In case of no sample being delivered by the master, you must state this fact on the report and issue a
letter of protest to the master.
Very important: The Inspector must verify that the quality of the product complies with the specification
advised before discharging. When Repsol is the Receiver and the binding quality is determined at ship´s
tanks before discharging, then discharge will only commence if the quality meets each specification. It is
the Inspector´s responsibility to make sure that this
requirement is accomplished and alert if it is not.
Regardless of the contractual binding quality, the following samples are to be taken for analyzing in
the refinery laboratory:
1 x 500 cc of each ship´s tank before discharging.
Recommended sample containers for this product group are:
‐ Pressurized sample cylinder (For liquid)
‐ Gas bladder or bag (For vapor)

ANNEX E
Letter of Responsibility
On behalf of our principals, we must extend to you the following letter:
We were unable to carry out a visual tanks inspection due to the fact that the cargo tanks
were under inerted atmosphere.
The vessels cargo tank suitability remains therefore at Owners responsibility for any
contamination or damage thereby sustained, as well as any consequential contamination or damage
arising there from.
Whilst every effort has been made to comply with tank inspection instructions we cannot
be held responsible for those areas beyond visual inspection (such as pumps, lines) and/or the
effectiveness of advised tank cleaning methods.
Note: Due to the nature of the cargo to be loaded and the previous cargo (es) carried by the
vessel, commencement of loading of this cargo depends on obtaining express permission from
our principal(s).
