The main purpose of an SSIV is to protect the platform and its personnel from unintended release of hydrocarbons. The SSIV has a fail-safe design, and will close on loss of an active signal from the ESD system. The SSIV can be installed as a standalone module or as an integrated component with, for example - a riser base. It can be retrieved separately, or installed as part of a pipeline or structure. EAB has this knowledge and execute EPC deliveries of SSIV modules.
