The publication by the Australian Marine Safety Authority (AMSA) of Safety Alert: 02/2021 aims to raise awareness of the correct use of hydrostatic release units, for both float-free life rafts and float-free EPIRBS.
The Hydrostatic Release Unit (HRU) is designed and approved to automatically deploy a life raft or EPIRB in the event of a vessel sinking. HRUs operate between 1.5 and 4 metres of water depth, to release the securing mechanism for the life raft or EPIRB.
AMSA inspectors often identify circumstances where HRUs are incorrectly fitted. In 2021, AMSA has issued over 100 deficiencies in relation to deficient HRU Continue reading “Use of hydrostatic release units safety alert issued by AMSA”









Interest in emerging battery technologies in the maritime industry has seen a rise in recent years. The possibility for reducing energy costs and environmental impact makes battery technology valuable for maritime use. Batteries can be used in a wide variety of applications, like peak-shaving in hybrid systems to help engines work at optimal loading and increase efficiency.
