At T-ISS, we have several release hooks for liferafts and rescue boats. Release hooks will make sure your liferaft or rescue boat will release itself into the water in times of emergency. Some release hooks let go automatically while others can be handled manually. In this article, we tell you all about our release hooks and how they operate.
The T-ISS Liferaft / Rescue boat hook PX01 is a combined automatic release hook. It can handle rescue boats and liferafts up to 35kN. You can use this hook for rescue boats with a davit load less than 3500 kg or a davit launched liferaft up to 40 pax.
The PX01 has two modes of operation to allow for safe evacuation regardless of the conditions:
1. Automatic release when the craft enters the water.
2. Manual release when waterborne if auto-release is not possible.
The T-ISS Liferaft release hook PX02 is an automatic release hook for davit launched liferafts. It can handle a safe working load of 25 kN. The hook can be operated as an automatic release hook, releasing when the raft enters the water, or as a manual release hook.
The T-ISS Rescue boat hook PX03 is a manual release hook. It can be operated by one person. By pushing the release handle in the upward position, the hook will open. The PX03 can handle a safe working load of 15kN. In addition, this one is easy to operate and comes with a 5 year service life.
A hydrostatic release unit (HRU) is a pressure activated mechanism. It is designed to automatically deploy a life raft, when certain conditions are met. In case a vessel sinks, the HRU will activate and release the life raft on a depth between 1,5 and 4 meters. The pressure of the water against a diaphragm within the sealed casing causes a knife to cut through a rope. Then, it will release the life raft.
Our SeaMate Ve-1 hydrostatic release unit is designed to operate in all conditions. From extreme heat to the polar environment. In the exceptional situation your vessel sinks, the T-ISS SeaMate Ve-1 will automatically release your life rafts and EPIRB’s.
Our innovative design increased the reliability, that’s why the T-ISS SeaMate Ve-1 has an expiry life of 3 years. This means you only replace the HRU every 3 years, instead of 2 years which is common.
Besides the cost saving, this also reduces the environmental footprint. The SeaMate Ve-1 hydrostatic release also fits on remote release systems. This enables you to release life rafts remotely.
