Damen Shipyards Group has launched an ice class trailing suction hopper dredger (TSHD) 2000 for Russian Port Agency FSUE “Rosmorport”.
Song Thu Corporation shipyard in Da Nang, Vietnam, is building the Damen TSHD 2000 Severnaya Dvina under Russian Maritime Register of Shipping (RMRS). It is the industry's first ice class TSHD built directly under RMRS technical supervision in thirty years. Following delivery, the 2000 m³ Severnaya Dvina will maintain navigational depths and provide safe shipping in the Arkhangelsk Seaport basin and approaches.
Severe Weather Conditions
FSUE “Rosmorport” awarded the contract to Damen following an open tender in 2013. Damen tailored the TSHD 2000 design to meet the high specifications required to operate the vessel in the severe weather conditions of Russia’s northern region, with air temperatures ranging from -30°C to +40°C.
The Severnaya Dvina has a reinforced bow with ICE 1 notation to be able to dredge in waters approaching the freezing point, and then relocate with icebreaker support.
