VOSTA LMG Builds TSHD for Dutch Dredging

Tuesday, May 29, 2007
VOSTA has been awarded with the contract for the delivery of a complete engineering and component package for a trailing suction hopper dredge for Dutch Dredging BV (Baggerbedrijf De Boer b.v.) in The Netherlands. The complete order consists of the design and engineering of a 2800 m3 trailing suction hopper dredge, including the delivery of the dredging equipment, propulsion systems, electrical installation, automation, hydraulic installation, navigation & communication systems. The vessel will be built under VOSTA LMG supervision at the Ben Kien Shinco Shipyard based in Hai Phong, Vietnam. This shipyard is part of the Vietnamese Shipbuilding group Vinashin. VOSTA LMG and Ben Kien Shipyard have co-operated before for the construction of two cutter suction dredges.

This trailing suction hopper dredge is designed according to latest technology. The optimised bulbous bow will have a positive influence on speed and fuel consumption. Special measures have been taken to increase propulsion efficiency and to reduce noise and vibration. The TSHD will be equipped with a 800mm SB suction pipe with a dredging depth of 30 meter. The vessel will be equipped with 12 bottom doors and a MK-3 VOSTA LMG bow coupling for discharge purposes. Two VL 750 dredge pumps will be installed as well as a number of VL standard gate valves in various diameters. One pump will operate as the dredge pump and the second one as delivery pump. The VOSTA LMG Dredge Automation modules include suction pipe monitoring and control, draft and load monitoring, production monitoring, dredge control and load calculation.
