Aker and Deltamarin design Arctic tanker
Aker Arctic Technology Inc and Deltamarin Ltd have joined forces to design a modern Aframax tanker concept for arctic use.
Intended for crude oil and oil product transports, the 266m vessel is strengthened to ice class PC5 level and is capable of continuously breaking thicker than one metre level ice. The bow and hull shape of the vessel are said to have the best balance of open water performance with icebreaking capabilities, while the specially designed hull strengthening is also said to improve safety in operations in the arctic waters.
“The design integrates optimised ice breaking and open water performance as well as the latest energy efficiency features applied together with the Polar Code requirements,” said Aker Arctic’s project manager Riku Kiili and Deltamarin’s director of ship design Markku Miinala.
“This unique combination results in an affordable building and improved transport economy by cost efficient operation. The design can be fine-tuned according to the customer’s wishes,” they added.
The hull is equipped with an Ice Load Monitoring System, which measures ice loads from the hull and provides online support to the officers ensuring safe operations. The two companies say the system will also help the ship owner in the long term by analysing the data and creating information for the optimal operations. The emphasis has also been on winterisation for cold climates in all aspects of the concept design.
Equipped with two CP-propellers and shaft lines directly coupled with slow speed diesel engines, the vessel can also be fitted to run on LNG with dual fuel engines. There is also a possibility for two bow thrusters and shaft PTO/PTI (Power Take Off / Power Take In) systems.
The vessel can operate on the Northern Sea Route during the extended summer months, and with assistance even longer. During the winter months the vessel can operate in other sub-arctic sea areas such as the Baltic Sea or Sakhalin.
