7.1    Extracts from FOSFA code of Practice for Member Superintendents

Ship’s Tank – Fitness and Cleanliness

Investigate (including inspection of ship’s log) and report on previous three cargoes and method of cleaning after last cargo, including note of chemicals used in cleaning. Such report to be counter-signed by the owners, Master or authorised agent. Acceptability of tank with or without further specific testing and cleaning to be checked against current contract terms and categorised product lists, as may be currently issued by FOSFA International. Where such review requires specific testing and cleaning, this can only be progressed by the superintending organisation where specialist operatives are available and specialised laboratory facilities close at hand.

Otherwise, if tank empty, safely accessible, gas-free, etc., inspect walls, bulkheads, bottom for cleanliness and surface condition, coated or otherwise. Check no internal fittings of copper or copper alloy.
Report on condition of tank coating. Report on residues, loose scale, hardened product adhesion to cross-members, etc. Where chemical cleaning has taken place, it is essential to check for residual chemicals. Report on any unusual foreign odour, identify if possible. Where not accessible, a very limited inspection can be made from deck manholes. If the condition of tank unacceptable – reject.

Mobile Tanks – Cleanliness

External and internal condition and state of cleanliness and dryness should be readily inspected. Although requirements generally similar to those applying to ships and shore tanks, the nature of their application, particularly road vehicle tanks, is such that they can be cleaned quickly and effectively.
