Thrust Maritime have two DNV approved A-Frames available for rent; they are identical and have a 50t SWL (design load of 82t, which allows for a 25t SWL capacity when carrying people). They are fully certified to DNV 2.22 Lifting Appliances for use in the Offshore environment.

​

The A-Frames' primary use is for the recovery of HRC's (Hyperbaric Rescue Chambers) and SPHLs (Self Propelled Hyperbaric Lifeboats).  Although they can be used for a varierty of other purposes, including:

• Recovery and deployment of large subsea assets

• Deployment of concrete mattresses;

• Deployment of subsea structures;

• Core sampling;

• ROV deployment.

 

The A-Frames have been designed to suit a wide variety of vessels allowing rapid installation.  Typically the A-frames are fitted to Anchor handlers (AHTS), or Platform Supply Vessels (PSVs), although they can also be fitted to smaller lighter vessels.
