Fuel spillage

The helidecks of offshore facilities are usually provided at the highest portion of the offshore installation for avoidance of obstructions during aircraft maneuvering and available space. As a result the roof of the accommodation is typically selected. The location also facilitates evacuation of personnel from installation by helicopter due to its proximity to the highest concentration of personnel. This enhances one of the avenues of escape from the installation but also exposes the accommodation to several hazards. The accommodation becomes subject to the hazards of helicopter crashes, fuel spillages, and incidental helicopter fuel storage and transfer facilities. 

Pollution as a result of irrigation, industry, sewage, fuel spillage, etc.

Transportation of both containers with SRW and those of types 6 and 11 containing water and partly damaged SFAs/fuel spillage from SRW TSF to a shelter is a potentially nuclear and radiation hazardous operation. Consequently, prior to perform container unwatering, one needs detailed development of process technology for container transportation in compliance with appropriate safety requirements, develop and manufacture special transport facility (or reequip the existing transport facihties), and develop the safest shipment route (possibly, construct a new road).

The heli-deck should be elevated above the accommodation by an air gap to ensure vapor dispersals from fuel spillages. Fuel loading and storage for the helicopters should be located so the tanks can be jettisoned or disposed of in an emergency if they are located near the accommodation. 

If it becomes necessary to fill a gasoline or diesel fuel lift truck with a portable container, only UL/FM (Underwriters Laboratory/Factory Mutual) cans may be used. The can must have the proper pouring spout to avoid fuel spillage.
