Vestdavit has supplied dual point boat handling solution to the seismic vessel »Ramform Hyperion«. It is to lift and lower tender boats in high waves.

The boats work as fast rescue craft with six crew, as tenders with 20 persons on board and as lifeboats with capacity for 40.

[ds_preview]»Ramform Hyperion«, under delivery by Mitsubishi Heavy Industries, features a distinctive ‘5th generation’ hull form that is 104 m in length and an extraordinary 70 m across the beam, designed to deploy ultra-wide streamer tows aft. As a result, it has only a short, flat parallel ship side for tender boat launching and retrieval, necessitating a 12 m outreach painter boom.

»A standard davit solution was not compatible with the design of the ship itself; to work, it would be necessary for the vessel itself to be longer,« says Atle Kalve, Development Director, Vestdavit.

Two hydraulic davits

Like its predecessors, »Ramform Hyperion« is fitted with two Vestdavit H – 10000S dual point hydraulic davits, one on each side, with a dual winch system specifically developed for the application. Both the boom and the davits are computer-controlled and feature in-built auto tension and shock absorption optimising safety and crew comfort on launch and recovery in high seas. A 200 t Vestdavit shock absorber system takes peak loads out of the paravane doors during seismic operations to prevent the holding ropes from snapping.

The »Ramform Hyperion« is the last of four ships built to the seismic sector’s all-time highest specifications, completing a project that shows the way distinctive design also demands innovation from the equipment keeping ships safely in service.
