Allseas orders higher-spec crane for Solitaire

Offshore staff

SCHIEDAM, the Netherlands – Allseas has commissioned Huisman to design and manufacture a new offshore mast crane for the pipelay vessel Solitaire.

The new 850-metric ton (937-ton) crane will replace the current 300-mt (330-t) model, and will provide up to 1,600 m (5,249 ft) hook travel single fall.

It will be equipped with an active heave compensation system on the main and whip hoist to counteract the vessel’s heave motion when landing a load on the seabed.

Use of a splittable block on the main hoist will allow the number of falls to be adjusted from eight to four without re-reeving - adjustment, Huisman claims, helps optimize the lift with the required load and speed.

These features should benefit installation of heavy loads for deepwater subsea production systems.

Delivery of the new crane is scheduled for Oct. 1 at Huisman’s plant in Fujian, China.
