Damen Shipyards Group has launched its ice class TSHD 2000 hopper dredger to be delivered to Russian port agency Rosmorport as part of a contract signed in 2013.
Under the terms of the deal, the 2,000m³ Severnaya Dvina vessel will be built by Song Thu Corporation shipyard in Da Nang, Vietnam, under Russian Maritime Register of Shipping (RMRS).
The 80.35m-long trailing suction hopper dredgers will have dredging drought of about 5.1m and a capacity to accommodate 12 crew members.
According to Damen, the vessel is the industry’s first ice class TSHD built directly under RMRS regulations in three decades.
Upon delivery, the vessel will maintain the navigational depths at Arkhangelsk Seaport basin, operating under air temperatures ranging from -30°C to +40°C.
The vessel will be equipped with a complete Damen dredging equipment dredge and instrumentation package that includes an Ø600mm trailing pipe, hydraulic winches, telescopic overflow and five rod-actuated bottom doors.
Additionally, it has a low pressure Damen inboard dredge pump to facilitate the hopper loading process.
Damen project manager Harrold van Vliet said: “The Severnaya Dvina has a reinforced bow with ICE 1 notation so it can continue dredging in waters approaching freezing point, and then relocate with icebreaker support.
“During the engineering phase we held regular design review meetings with the client to ensure we delivered exactly the capability they required.”
Damen has previously delivered TSHD 1500 Jean Ango to France-based Dragages-Ports and TSHD 2500 Barito Equator to the Indonesian dredging company Pelayaran Fortuna Nusantara Megajaya (PFNM).
