Redundant Public Address and General Alarm (PAGA) and Global Maritime Distress and Safety (GMDSS) systems. The PAGA system can
be connected and integrated in host platform via fiber optical cable.
–  Fire & Gas detection system (F&G) monitoring presence of flammable gases, fires and smoke by detectors located over the entire
installation. F&G is designed to initiate shutdown actions, release fixed fire fighting systems, alert personnel and isolate ignition sources
based on a “2 out of N” voting.
–  Emergency Shutdown system (ESD) is based on three levels: Abandon Platform Shut Down (APS), ESD High, ESD Low.
–  EX –proof deck equipment
–  Active fire protection systems are installed based on the Fire and Explosion Strategy.
–  The helideck have a DIFF system (Deck Integrated Fire Fighting) for efficient fire fighting.

Bridge to host platform, helicopter, lifeboats, life rafts and ladders to sea in said order.
–  Haven has 5 davit-launched TEMPSC lifeboats adopted to Norwegian requirements. All lifeboats placed in bow and facing out from platform. Each lifeboat has a capacity of 120 persons, thus four lifeboats will cover 100% POB.
–  Haven is equipped with 17 davit-launched life rafts distributed over 6 life raft stations on the periphery of the vessel. Each life raft has a capacity of 29 persons of 90 kg, giving a total capacity of 492 persons (100% POB).
