SEAMATE

Designed and fabricated from tough non-corrosive materials, the Seamate™ HRU represents innovative thinking and real cost saving benefits in automatic Hydrostatic Release Units (HRU).

 

At a depth of 1.5 to 4 metres, water pressure alone is sufficient to operate the release mechanism to free life rafts and emergency beacons for deployment, without any human input. This offers considerable advantages both in reliability and performance as the releasing system does not depend on a pyrotechnic device or a battery to release the life raft or emergency beacon.

 

Seamate™ HRU’s meet all international regulations and each unit is individually tested to ensure that it is the most reliable HRU in an emergency situation.

 

How Does it Work?

The Seamate™ Hydrostatic Release Unit can be fitted to EPIRBs and any container packed life raft, from 4 – 150 person capacity to allow unattended deployment in a vessel sinking emergency. It requires no service, maintenance or spare parts after installation.

 

At a depth of between 1.5 to four metres, water pressure depresses an internal diaphragm within the device. This operates the cutting mechanism within the release housing that secures the raft container to its cradle or mounting position.

 

The life raft will then float free of the sinking vessel and rise towards the surface with the raft’s painter line paying out as the vessel continues to sink. When all the free length of painter line is paid out, the inflation mechanism of the life raft is activated; the life raft inflates and continues to rise towards the surface.

 

At this point of inflation, the weak link on the HRU breaks and allows the life raft, now unattached to the vessel, to continue to float to the surface, ready for boarding.
