In beginning July 2008 VOSTA KMG concluded a contract with J.J. Sietas KG, Schiffswerft GmbH & Co., Hamburg, Germany, for the supply of each one engineering and component package for the construction of two Trailing Suction Hopper Dredges (TSHD) of 5.500 m3 hopper capacity each.

As VOSTA LMG´s Partner Yard Sietas will build these two sister ships and supply them to Josef Möbuis Bau-Aktiengesellschaft, an affiliated company of the Austrian STRABAG AG.

The first TSHD will be delivered end October 2010 followed by the second one end of January 2011.

VOSTA LMG has developed a new modular type Trailing Suction Hopper Dredge, for the building of which Sietas is an ideal partner yard. Through application of modular block building of sections and repeated use of standardized components, the building of TSHD ´s with hopper volumes of approx. 4.200m3, 5.500m3, 7.200m3 can be achieved without major design changes.
