Ships and Offshore Technology
Inflatable buoyancy support system for marine immersion protection
Part 1.Air supply system
1 Scope
This document specifies the general requirements, installation and start-up requirements for the air supply system of the inflatable buoyancy support system used for ship immersion protection.
Support systems provide additional buoyancy to damaged vessels and can be installed in the engine room and/or cargo hold.
This document ensures the functionality of air supply systems that use a gaseous medium (eg inert gas) to inflate buoyancy tanks of buoyancy support systems.
