HOBART, Australia – The 230-ft (70-m) fast crew boat Muslim Magomayevwas named at a ceremony at the Incat shipyard last week. The DP-2 class vessel will be delivered to Caspian Marine Services to operate fast crew transfers for 150 offshore workers to numerous installations in the Caspian Sea.

This is the first time four retractable thrusters TH300MLRN have been fitted for a single crew boat application, Incat Tasmania claims. The Thrustmaster fixed-pitch propeller through-hull azimuth thrusters are capable of retracting completely into the hull, and are configured for vertical variable-speed electric motor input. The motor travels up and down with the thruster, so the drive line is never disconnected.

Following sea trials the boat, constructed from lightweight marine grade aluminum, is expected to depart later this month to Baku, Azerbaijan. Its 16-m (52-ft) beam is narrower than for a conventional Incat in order to pass through the Volga-Don canal system to Baku.

Incat claims the vessel’s high speed will provide operational efficiency compared with helicopter transfer for both passengers and cargo, while the semi-SWATH hull design, along with active ride control, should reduce stress on passengers in transit.

Muslim Magomayev is around 200 metric tons (220 tons) deadweight and is capable of carrying 150 passengers and 14 crew and 130 metric tons (143 tons) of deck cargo, in up to 40 knot winds and seas of 3 m (9.8 ft) significant wave height.

The 275-sq m (2,960-sq ft) cargo deck should allow thevessel to complete cargo delivery over a range of 400 nautical mi at speeds of up to 35 knots.
