Dockwise Contributes to a Happy Ending of Statoil's 'Snow White' Project
The world's largest heavy transport vessel the Blue Marlin of Dockwise Shipping in Breda, The Netherlands is heading for Melkøya in northern Norway carrying Statoil's barge-mounted LNG process plant for Snøhvit (Snow White).
Dockwise was awarded the contract by Statoil for three sea transports of the essential parts of the Snøhvit LNG export facility at Melkøya in northern Norway.
First the heavy transport vessel Tern transported the Snøhvit barge-mounted Meg Unit and Substation from Flushing, the Netherlands to Melkøya. After a voyage of 7 days the Tern arrived at her discharge location on February 13, 2005.
The second transport was performed by the Swan. The barge-mounted Snøhvit coldbox was floated on the Swan in Flushing, the Netherlands and delivered to Melkøya after a 5-days voyage on May 6, 2005.
The third, final and most impressive transport, the Snøhvit barge-mounted LNG process plant, is performed by the world's largest heavy transport vessel of Dockwise the Blue Marlin of Dcokwise. The process plant has been floated on board the Blue Marlin in Cadiz, Spain, whereafter the Blue Marlin has set sail for Melkøya on June 30th. It is expected that the Blue Marlin will deliver the process plant to its final destination on 11 July. This massive structure represents a crucial component of Europe's first export facility for liquefied natural gas (LNG), the Hammerfest LNG plant on Melkøya.
The LNG process plant has a weight of 34,760 ton, an overall length of 175 meter, a width of 69 meter and a height of 60 meter.
The largest vessel of the Dockwise fleet the 76,061 dwt Blue Marlin has a length of 224.50 meter, a width of 63 meter with a deck space of 11,227 square meters.
According to Project Manager Gerard Pilger of Dockwise Shipping in Breda; "As this LNG process plant is designed for an onshore facility, the construction of its module supports is more sensitive to motions than compared to the designated offshore facilities we transport regularly. Weather conditions while sailing across the Bay of Biscay and the North Sea from Spain to Norway, can sometimes be unfavorable and could cause higher accelerations than allowable. For this reason a motion monitoring system is installed, which registers and interprets the motion response on-line and provides input to the heading control for the captain. When necessary the captain of the Blue Marlin can take the appropriate actions like slowing down or changing course. Furthermore, the redundancy in propulsion of the Blue Marlin makes this vessel extremely suitable for heading control necessary for this kind of cargoes sensitive to motions".
The attached photographs show the heavy transport vessels Tern, Swan and Blue Marlin all heading for Melkøya in northern Norway. The picture of the Blue Marlin has been taken while passing the English Channel on July 5th.
