Icebreaking Special Vessels
Two icebreaking supply ships for operation in the Caspian Sea were delivered in 1998. The Arcticaborg and Antarcticaborg utilize Double Acting operation with stern first in order to reach the drilling platform in winter time.
M/T Tempera and sistership M/T Mastera are the first purposely built Double Acting Tankers
A Double Acting Arctic Container Ship has been developed for Norilsk Nickel, for operation on the Northern Sea Route
The new vessel is a prototype for a series of potentially several vessels which are to replace the current SA-15 type vessels that have been in successful use for the last twenty years. Also these vessels were built in Finland by Wärtsilä and Valmet shipyards in the 1980’s. The Arctic Container Vessel was built by Aker Yards, for delivery in early 2006. See also Press releases.
Icebreaking stand-by and supply vessel for Far-Eastern Shipping Company (FESCO)
The ship design is based on the “double-acting” concept for icebreakers, which was developed by the Arctic Technology Centre (MARC), part of Kvaerner Masa-Yards Inc. The “double-acting” concept has now become an industry standard. In this concept the vessel meets the most difficult ice conditions moving with the ship’s stern first, using azimuthing electric propulsion. By this, less power is needed and the ship’s bow can be optimised for efficient open water operation. The operating conditions in the Sakhalin area are demanding with freezing temperatures down to -40 degrees C and difficult ice conditions with ice ridges up to 20 metres deep and solid ice exceeding 1,5 meters in thickness.
The current ship design is a result of the long term R&D activity by AARC. This activity started already in 1989 with research on the operational conditions offshore Sakhalin and has continued in form of different research and development tasks for the potential operators and oil companies in the area and in co-operation with several Russian organisations.See also Press releases.
Several icebreaking offshore vessels have been built over the years.
Research vessels for Antarctic and Arctic duties have also been built and developed. The Antarctic/Baltic icebreaking research vessel Aranda, for Finland, was built in 1989. Design references include the Aurora Australis, Australia (design/material/supervision, 1989), James Clark Ross, United Kingdom (preliminary/contract design, 1991) and Nathaniel B. Palmer, USA (conceptional design,1989).
