IJMUIDEN, the Netherlands – Offshore Ship Designers (OSD) has co-designed a new shallow-draft anchor-handling tug supply (AHTS) vessel with owner Ark Shipping, an offshore logistics service provider.
TheAHTS Antarctic is partly based on another OSD-designed vessel, the Arctic, delivered to the same company in 2012.
The DP-1 vessel has a Bureau Veritas Ice Class Notation, and is equipped to operate in extreme conditions in the northern Caspian Sea, where ice can build up to 80 cm (31-in.) deep during winter.
Construction of the hull from special-grade steel should allow the vessel to operate in temperatures down to -25 to -30 C° (-13 to -22°F). The hull has also been optimized to have a relatively low weight for an ice-class 1A vessel.
Antarctic’s large breadth is said to provide a stable platform for standby rescue, supply and anchor-handling operations under extreme conditions.
The vessel can supply and load cargoes such as cement, liquid mud, fuel oil, fresh water and black water. Its minimum draft in a light operating condition of around 2.5 m (8.2 ft) is said to ease access to the shallower parts of the Caspian Sea.
Antarctic has a Standby Rescue Vessel class notation for 100 survivors, with the accommodation designed to provide room for rescued individual.
Its total propulsion power is 4.923 MW and 6,600 HP, with six rudders, a triple steering gear and a double-cylinder set-up.
Three Cummins QSK60 Engines drive three high-thrust propellers, a configuration said to ensure a high bollard pull and good maneuvrability, even in icy and shallow waters.
