Measures For Handling Cargo Oil Having A Flash Point Exceeding 60c

Oil tanker at sea

Handling cargo oil having a flash point exceeding 60c without maintaining cargo oil tanks in inert condition need extreme caution. Confirm that use of IG is not required by regulations at the discharging port and shore facility. Refer to the special precautions as listed out in the latest edition of ISGOTT for above such operations. Also, a formal (stage 2) Risk Assessment will need to be carried out and the office informed, prior to such decision.

Ensure that sufficient reliable evidence available that the flash point of the cargo oil is above 61 degree C and the temperature of the cargo oil does not exceed 5 degree C less than the flash point.

However, when cargoes with a flashpoint exceeding 60 degree C are carried at a cargo temperature higher than their flashpoint less than 5 degree C, the tank should be maintained in an inert condition.

If the previous cargo oil is having a low flash point, purge the inflammable gas by IG until the level of the gas reduced down to 2% by Volume or less beforehand.



If another cargo oil having a low flash point has been loaded into other remaining tanks, prevent the mixing of such vapor by isolating vapor of such grades.

Cargo oil tanks must be inerted prior to washing the tanks with high temperature water.

Take the following measures cargo discharging operations.
Ensure that flame arrestors are fitted in vent posts.
Take preventive measures against static electricity
Refer to relevant Chapter in the latest edition of ISGOTT.
