About this file

This document provides minimum requirements for cleaning tanker cargo tanks in preparation for loading various petroleum and chemical products. It specifies cleaning requirements for different product types based on the last three cargoes carried. Aviation fuels and other sensitive products require stringent cleaning including hot water washing, draining, and fresh water rinsing of tanks and lines after cargoes containing biodiesel, crude oil, or other contaminants. Special procedures including isolation of piping systems and vents are mandated for loading thermally stable jet fuel to prevent contamination. Notes provide additional cleaning guidelines for cargoes containing water-soluble chemicals or ethanol, and restrict loading aviation fuels after crude oil or gasoline cargoes due to risk of residue contamination.

TYPE VESSEL CLEANING REQUIREMENTS LEGEND

A All cargo lines shall be dropped, tanks stripped, ballast residue removed.

B All cargo and vent lines shall be drained of previous product and flushed with cold water. Cargo tanks must be thoroughly machine washed using cold water.

Cargo tanks must be free of water, loose rust, sludge, mud, silt, etc.

C The same as for “B,” except that hot water shall be used instead of cold. If tank interiors are coated, water temperature should not exceed 58°C (136°F).

D Cargo tanks and systems shall be processed in accordance with the instructions contained in EI HM 50 Guidelines for the cleaning of tanks and lines for marine tank vessels carrying petroleum and refined products.

E Not to be loaded without special cleaning instructions. Three clean product/zero biological content intermediate cargoes required. (See Note 5 below) F Special tank preparations and cargo handling is required for JPTS, to prevent contamination. Tanks used for loading must be stainless steel or coated with an approved epoxy. Coating must be adherent: no flaking, peeling, or blistering. Prior to loading JPTS, tank cleaning requirements are: tanks must be machine washed with hot water, if cleaning chemical and/or salt water is used, the final wash must be with fresh water. Tank bottoms, interior bulk heads, and internals must be completely free of sediment, scale, and other contaminants. Tanks must be dry and all liquids completely removed from the tank’s lines after cleaning, must be flushed with fresh water, drained and free of all water. Loading and unloading system must be completely isolated. This will be accomplished by completely separate piping systems or by use of blinds. Valves will not be depended on to effect isolation. Cargo tank valves will not be considered as part of the “double block” requirement for cargo system segregation. No common lines will be used. Steam smothering lines should have at least two valves that can be sealed from the main line to the tanks, or a blind installed that can be readily removed. Each tank will have its own individual vent. If ship has a common vent system, tanks used for JPTS must be isolated from balance of the vent system.

NOTES:

1. See Vessel Cleaning Requirements Legend for cleaning type code (A, B, C, D, E, F) details.

2. This table is included as a guide only. Requirements for tanker cleaning are determined by MSC vessel cleaning policy. Contact DLA Energy Quality Operations Division for tank cleaning requirements for any product not listed in the Table. If tank contains ballast water or water used for tank cleaning/washing, every effort shall be made to remove this free-water to the minimum level possible by draining or by use of a pump.

3. There are no circumstances where a crude carrier is capable of cleaning tanks, pumps and lines sufficiently to load an aviation fuel immediately after a crude cargo.

Crude carriers converted to a distillate diesel, aviation fuel or naphtha-based fuel must carry three cargoes of a commercial like product without a quality incident.

4. Gas free, lift scale and mop. Consideration may be given to substituting mopping by enhanced stripping and drying per EI (Energy Institute) HM 50 Guide.

5. FAME (Fatty Acid Methyl Ester) Contamination:

Aviation Gasoline or Aviation Kerosene/Turbine Fuel (Aviation Fuel Products)

- To avoid contamination from FAME in Aviation Gasoline, Aviation Kerosene/Turbine Fuel cargoes. See below instructions.

-- Following cargoes with pure biodiesel (B100) or any cargo with FAME content greater than 5 vol % (B5): Prior to loading Aviation Fuel Product cargoes requires three intermediate cargoes and a subsequent compatible Aviation Fuel Product cargo. The three intermediate cargoes and the compatible Aviation Fuel Product cargo SHALL NOT contain FAME content greater than 5 vol % (B5). When any of the last three cargoes have consisted of diesel or heating oil products, FAME testing shall be conducted for each cargo; attestation as described in the RFP is not sufficient for these products. Examples of diesel or heating oil products include, but are not limited to, F-76, DF1, DF2, DS1, DS2, DSS, DSW, MGO, Gasoil, FS1, FS2, FS4, FS5, FS6, and IFO. Evidence by presentation of CoQs representing the last three cargoes with FAME testing (EN 14078 and ASTM D7371) demonstrating B5 or less shall be provided as proof. In scenarios where FAME testing (EN 14078 and ASTM D7371) was not conducted for a diesel or heating oil product, or such data is unable to be provided for all three of the last cargoes, the vessel shall be assumed to contain FAME greater than 5 vol %. The vessel tanks shall be evaluated and cleaned under the Minimum Requirements for Preparation of Tanker Cargo Tanks table above under procedures for Biodiesel Blends greater than B5 procedures.

Alternatively, another vessel with FAME testing for the last three cargoes conducted may be nominated instead.

-- Tanks shall be in good condition and washing shall be particularly stringent, including flushing of pumps and lines, followed by drain and mop, at a minimum. A fresh-water rinse is required if sea water is used. Uncoated tanks shall be hot water washed and have loose bottom scale removed prior to loading an aviation fuel product cargo load.

-- Following cargoes with a FAME content of 5 vol % or less (B5 or below): Prior to loading Aviation Fuel Product cargoes, recommend a hot water wash, including flushing of the pumps and lines, followed by draining, at a minimum. A fresh-water rinse is required if sea water is used.

Special note:

Specifications for sensitive grades will require extreme care during sampling to avoid contamination from previous cargoes or buildup of residues. To reduce the possibility of drawing unrepresentative samples, cleaning of sampling equipment, vapor locks, stand pipes and stilling wells is recommended as part of cleaning when tanks have previously held cargoes containing FAME.

6. Water soluble chemicals: include Ethanol, Mono Ethylene Glycol, Di Ethylene Glycol. See page four (4) for additional water soluble/miscible chemicals.

7. Previous automotive and aviation gasoline cargoes for loading JPTS are unacceptable unless the concentration of lead is verified to be less than 13ppm.

8. Certain products to be loaded on a tanker must not only consider the last cargo carried, but the 2nd and 3rd to last cargoes as well. These products include aviation turbine fuels and F-76 fuel oil, naval distillate. Previous cargoes of Crude oil and products containing FAME are addressed in notes 3 and 5. Other 2nd and 3rd to last cargoes of concern include, but are not limited to, raw vegetable oil, lubricating oils, heavy fuel oils, and various chemicals. Determinations for acceptability of 2nd and 3rd to last cargoes carried prior to loading aviation fuel and F-76 will be made on a case-by-case basis using applicable Certificates of Analysis, Certificates of Quality and other analytical data.
