Incat Crowther wins utility cat order

Incat Crowther, Newpors, NSW, is designing a second utility catamaran for Offshore Unlimited. This vessel follows the success of Unlimited, a 24 m utility catamaran designed for the same operator. Like its predecessor, the vessel will be built at Richardson Devine Marine in Hobart, with delivery expected in early 2010.

The new vessel will be a 29 m high speed catamaran work boat capable of carrying 50 tonnes of deadweight. The aft deck, with a cargo capacity of 24 tonnes, is configurable for multiple uses. It includes a large moon pool for exploration services, securing points for 2 x 20 foot containers, a Heila deck crane (capable of lifting 6.7 tonnes) and a removable hydraulic 5 tonne A-Frame (including a reel winch)

Like Unlimited, the new vessel will have a towing hook to enable it to undertake lightweight tug duties. The vessel will have a bollard pull of 12 tonnes.

The main deck cabin houses the galley, lounge and crew mess area, along with two officer cabins. Wash facilities are also provided on this deck, one with laundry facilities. Additional crew cabins in both the port and starboard hulls bring the vessel's total to 12 berths. There is a large pantry in the port hull. The upper deck wheelhouse features crew and passenger seating and well equipped work stations, whilst the central helm seat gives good all round visibility.

Two wing control stations are fitted forward on either side.

A tender/rescue boat is situated aft within easy reach of the deck crane.

The vessel will have a total capacity of 50 personnel, including the crew. It will have an extended range, allowing the operator to reposition the vessel far more effectively.

The vessel will become part of the fleet owned and operated by Offshore Unlimited, a Tasmaniancompany providing vessels to Australian waters with operations out of Dampier, Western Australia, and Mackay, Queensland.

Offshore Unlimited provides a range of offshore services including offshore installation re-supply, seismic ship re-supply, dive & ROV support, crew transfer and chase boat services.
