BMT provides more details of Caspian Sea OSVVessel & ROV News // February 1, 2002
BMT SHIPDESIGN is working with Ulstein Verft AS for the Scottish offshore company BUE Marine Ltd. Preliminary design work began in August 2001 and the vessel will arrive in the Caspian Sea in the middle of November 2002.
There are several design challenges which make this project unique. The water around the Kashagan field is very shallow and, while in the summer the weather is very hot, in the winter the sea freezes over. To account for this the vessel must be able to operate at air temperatures ranging from plus 40° C to minus 30° C, sea temperatures ranging from minus 1°C to 32°C and break ice up to 60 cm thick ahead and 1m astern. The draught must not exceed 4m under normal operation and 2.5m when icebreaking in shallow water.
The building and delivery of the vessel also pose huge challenges for the project team. The entire hull, with the exception of the superstructure, will be built in Poland and will be towed to Ulstein Verft at Ulsteinvik for outfitting. Once outfitted thevessel will be transported through Russia's canal system to arrive in the Caspian Sea in September 2002. Tight project timescales must be adhered to since the canals close for the winter in October each year.
Mike Burkett, Managing Director of BMT SHIPDESIGN said: "This is a very exciting project; not only is the design unique but it is believed that the Caspian Sea will be one of the richest sources of oil in the world in the coming decades. The area currently does not have offshore vessels of this type and is presently only served by smaller vessels, tugboats and barges. We believe that this project will lead to the construction of similar vessels in the future."
Managing Director Gunvor Ulstein of Ulstein Verft AS said: "We are pleased that we have established a relationship to a new customer with good contacts in a new and exciting market through close cooperation with BMT SHIPDESIGN."
