The cutter on the "Khaleej Bay" operates with 900 kW of power.
Hopper dredge Shenhua (see cover)
The trailing suction hopper dredge Shenhua was launched at Hudong Zhonghua Shipyard in Shanghai on Tuesday, May 18. Finalization, including sea trials, was underway at the beginning of September under the direction of Vosta's project manager Thomas Schattling. He expects final delivery to be by the end of October.
The dredge is being built by VOSTA LMG for Huanghua Port. With a capacity of 5000 cubic meters, the Shenhua is the largest known hopper dredge known to be built in China.
Board members of Huanghua Port and Hudong Zhonghua Shipyard participated in the launching ceremony, along with officials from VOSTA LMG.
Huanghua Port, on the northwest coast of China, belongs to the Shenhua Group and is the main hub for worldwide transport of coal excavated from mines in northern China. Continuous dredging is required to maintain the entrance to the port, which led the Shenhua Group to invest into their own hopper dredge.
VOSTA delivered the complete engineering package and the dredging components, and has complete technical responsibility for building the vessel.

The Khaleej Bay
VOSTA LMG was appointed by De Groot Nijkerk (recently renamed Damen Dredging) to design and supply the cutter system, spud system and dredging winches for a cutter suction dredge (CZ600) for Middle East dredge and reclamation contractor Gulf Cobla LLC.
The vessel was built at Abu Dhabi Shipbuilding Co. in Abu Dhabi, United Arab Emirates, and named Khaleej Bay on March 9, 2004.
The cutter and spud system, consisting of the ladder, cutterhead and spud carrier, were shipped to Abu Dhabi Shipbuilding Co. early in September 2003 and assembled under VOSTA LMG supervision. The dredge was commissioned at the end of February, 2004. The cutterhead (type SC-40), was designed to work with sand, clay and soft rock. The dredge will be working on various projects in the Middle East.

Hopper Dredge Mecca
The 10,000 cubic meter trailing suction hopper dredge Mecca was scheduled for delivery to the Suez Canal Authority. The dredge was built at Mitsubishi Heavy Industries in Kobe, Japan. Vosta project manager Joachim Pflug was in Egypt for final commissioning and sea trials at the beginning of September, with delivery to the customer expected before the end of October.
CSD500 for Iran
Vosta has received a contract to provide engineering and a components package for a CSD500 cutterhead dredge for SADRA Omid Chabahar, Iran. It is scheduled for completion in 2005.
The self-propelled dredge is equipped with spud carrier, spud tilting, anchor booms, and hydraulic capstans.
The component package will include a type SC10 cutterhead, designed to work in sand, clay and soft rock; dredge automation, an inboard dredge pump, electrical system, the complete hydraulic system and the propulsion units.
Engineering and a full service and training package will be provided by VOSTA LMG.
The dredge will be built in Iran by the owner in close cooperation with VOSTA LMG, and scheduled for completion in 2005. The owner plans to use the dredge for creating his shipyard basin and for maintenance work in the free trade zone of Chabahar.
