2. CARGO TANKS AND CARGO HANDLING FACILITIES
- Copper and its alloys such as brass, bronze, or gun metal shall not be used for any part of the system installation and means of transport that has contact with the oils or fats.
- Tanks, other than those of stainless steel, shall be coated, with an exception of mild steel tanks as specified in the FOSFA Operational Procedures. Only coatings suitable for food-grade products and for the carriage of the oils or fats shall be used. Zinc silicate coated tanks shall not be used for crude oil unless the acid value is 1 or under.

- Mild steel exposure in coated tanks to be minimal with no loose scale.
- Ship's tanks, which have been newly coated or fully re-coated, or stainless steel tanks that have been cleaned and passivated (witnessed by a qualified independent surveyor in case the cargo prior to passivation was non-FOSFA) in a dry-dock / shipyard / repair facility are acceptable after a period of 7 consecutive days. Cargoes carried prior to the date of such coating or passivation shall not be considered as relevant. The shipowner is required to provide the independent certification of such procedures and to declare the three previous cargoes carried.
- Heating coils within tanks, and tubes and internal shell of heat exchangers shall be of stainless steel construction only.
- Heat transfer medium shall be fully described on the FOSFA Combined Master’s Certificate.
- Cargo lines shall preferably be of stainless steel construction with sufficient drain valves.
- All valves which may come into contact with oils or fats shall preferably be of stainless steel construction.
- Tank access/cleaning hatches to be staunch and tight with suitable packing and gaskets compatible with the cargo.

- Ship shall comply with the requirements of the FOSFA Qualifications for ships engaged in the carriage of oils and fats, in bulk.
- Ship shall comply with the provisions of the FOSFA Operational Procedures for ships engaged in the carriage of oils and fats, in bulk as applicable to the cargo and voyage designated in these Operational Procedures, including:

- Certification in the form of a FOSFA Combined Master’s Certificate signed by the Captain / First Officer or an equivalent statement signed by the ship’s owners or authorized agent, applicable before any loading or cargo transfer.
3.2 Tank/ Cargo History
- Ocean carriers: the immediate previous cargo in the tank shall not have been a product appearing on the FOSFA List of Banned Immediate Previous Cargoes or shall have been a product appearing on the FOSFA List of Acceptable Previous Cargoes (whichever is appropriate) currently in force at the date of Bill of Lading.
- Transhipment vessels receiving cargo for carriage to or from the ocean carrier: the previous three cargoes in the tank shall have been products appearing on the FOSFA List of Acceptable Previous Cargoes except that in segregated stainless steel tanks, lines, and pumps the immediate previous cargo for such tanks, lines, and pumps shall be on the FOSFA List of Acceptable Previous Cargoes, currently in force at the date of the Bill of Lading, with the additional exception that transhipment vessels may have mild steel tanks provided the previous three cargoes have been oils and fats for edible and oleo-chemical use and/or molasses.
- Note: Transhipment in this context is the physical transfer of oils and fats whether by direct board-a-board transfer or via a direct shore pipeline, from one ship to another for the purpose of pre-carrying to the ocean carrier at load-port or on carrying from the ocean carrier at a customary transhipment port in the area of destination under a through Bill of Lading.
- Short sea voyage vessels (which are vessels used to carry oils and fats for edible and oleo-chemical use for further processing from load port to final destination, provided the distance does not exceed 2,000 nautical miles): vessels with mild steel tanks shall be allowed provided the three previous cargoes have been oils and fats for edible and oleo-chemical use and/or molasses.
- In all cases the immediate previous cargo shall have been not less than 60% by volume of the tank.
- Leaded products shall not be carried as the three previous cargoes.
3.3 Inspection and Certification
- Prior to receiving cargo ship’s tanks and related cargo handling systems should be fully inspected for cleanliness by a FOSFA Member Superintendent in accordance with the FOSFA Code for Practice for Member Superintendents, Part One. Inspections shall be certified in the FOSFA Certificate of Compliance, Cleanliness and Suitability of Ship’s Tank.
- Before any loading of, or transhipment to the ocean carrier, a statement in the form of the FOSFA Combined Masters Certificate shall be handed to the sellers/shippers or their superintendent.
- In the case of transhipment to the ocean carrier, a statement in the form of the FOSFA Combined Masters Certificate shall be handed to the Bill of Lading holders or receivers or their superintendents, before commencement of discharge at the port of final destination. In the event transhipment is arranged where no superintendent is present, a statement in the form of the FOSFA Combined Masters Certificate, or an equivalent statement, together with a certificate of cleanliness of ship’s tank and related cargo handling systems signed by the Captain / First Officer shall be handed to the Bill of Lading holders or receivers or their superintendents, before commencement of discharge at the port of final destination.
- Transhipment shall only be allowed under a through Bill of Lading and shall be restricted to the area of origin and / or customary transhipment ports in the area of destination, provided that the transhipment at origin is completed within the original contract shipment period and / or agreed extension period, except where transhipment takes place to protect the Master’s rights and the ship’s obligations under Maritime Law.
3.4 Cargo Heating Instructions

4. OPERATIONAL PRACTICES
- Physical operations at loading and discharging shall be conducted in accordance with the FOSFA Code of Practice for Member Superintendent, Part One.
- Two samples shall be taken at the commencement of loading at origin. A line sample at the deck of each cargo loaded; and A first one-foot sample for each ship’s tank loaded.

Ship shall pre-pump ashore to ensure cargo lines are free of contamination. Pre-pumping shall only be required when there is concern as to the immediate previous cargo. All pre-pumping time to count as used laytime.
- The lines and pumps system/s serving the oils and fats tank/s shall be dedicated to oils and fats during the entire voyage. Oils and fats systems shall not be cross-connected to any other cargo system to ensure complete segregation.
- Pumping from one tank to another on the same ship is not permitted except for the requirements of safety, cargo worthiness, and seaworthiness. Where pumping from one tank to another takes place, the Master shall provide a statement certifying the cleanliness of the ship’s tank/s and related handling system and the three previous cargoes in the tank/s to which the oil or fat is transferred and confirm the percentage by volume of the immediate previous cargo in the tank/s and the reasons for the transfer, signed by himself or authorized agent, to the Bill/s of Lading holders and/or receivers or their superintendents at the port of destination before commencement of discharge.
- Prior to discharge all additional handling systems such as hoses and deck manifolds shall be inspected for cleanliness by a FOSFA Member Superintendent. At the commencement of discharge, line samples shall be taken at the ship’s permanent connection for each cargo unloaded. Samples to be inspected for appearance and odour.
