Evaluating Ice Loads on Windmill Monopiles
As part of Aker Arctic’s own research and development work, a series of ice model tests were conducted in November 2023 to investigate the ice loads affecting windmill monopiles. Offshore windmills require robust foundations to withstand the harsh marine environment, including ice and waves. Similar to the planning of icebreakers or other ice-strengthened vessels, the testing of offshore structures with scaled models is a cost-efficient method to verify design adequacy before construction begins, ensuring suitability for the intended operational area. Crushing strength is

on China’s new state-of-the-art polar research ship is underway at Jiangnan Shipyard in Shanghai, China, with delivery scheduled for 2019. In 2012, the Polar Research Institute of China (PRIC) awarded a contract for the concept and basic design of the research icebreaker to Aker Arctic, who tailored the design for specific scientific missions in the Arctic and Antarctic. After the concept had been developed, Aker Arctic performed model tests in open water and ice at its Helsinki laboratory in order to verify the vessel’s performance. The new vessel will
Aker Arctic’s Ice Lab is Back in Acton
The Finnish icebreaking season typically ends in May. Around the same time, the cooling system in Aker Arctic’s ice laboratory in Helsinki, Finland, is turned off and the model basin is allowed to warm up for the annual summer maintenance break. Aker Arctic operates its own ice model testing facility at the company’s main office in Helsinki, Finland. Using the in-house developed FGX model ice, the 75-meter ice tank can be used to get reliable icebreaking performance predictions for ice-going ships and study other ice-related phenomena in model scale. Aker Arctic and its

MacGregor to Equip China’s New Polar Research Ship
The Polar Research Institute of China has ordered a new 14,300gt polar research vessel. Designed by Aker Arctic Finland, it will be the first vessel of its type to be built in China, though a shipyard has yet to be named. The 122.5-meter multifunctional icebreaker will be able to handle ice up to 1.5 meters thick, achieving a continuous icebreaking speed of two to three knots. It will have an endurance of 20,000 nautical miles and with a full 90-person crew, it will be able to cruise for 60 days without resupply. MacGregor, part of Cargotec, said it has won an order to supply MacGregor
Arctic Energy Exploration Efforts Heat Up
transits across the top of the word may not be large, there are a growing number of vessels operating in the ice. “Major oil companies continue to make major commitments to oil and gas exploration operations in the Arctic region,” said Mikko Niini, until recently the managing director at Aker Arctic in Helsinki, and now a senior management advisor. “We’re developing more independent cargo vessel solutions,” said Niini. Some of Aker Arctic’s more unusual designs include the double-acting ship (DAS) and the oblique icebreaker. The first DAS, Finnish tanker
Aker Arctic & Navis Engineering Agree DP Collaboration
Aker Arctic Technology Inc and Navis Engineering Oy have signed an agreement on joint development of Dynamic Positioning systems for ice operation. The companies plan to jointly develop next-generation DP-system technology tailored for ice operation by utilizing their core know how and technologies. The development includes improved control algorithms, testing of the systems and utilising new more intelligent technology to overcome the ice challenges. The development work will take place in close co-operation with Aker Arctic Technology in Helsinki and Navis Engineering R&D Centre in St.
Aker Arctic to Design Icebreaker for Finnish Government
The Finnish Transport Agency signed a contract with Aker Arctic Technology Oy for design of a new icebreaker for the government. Aker Arctic in cooperation with ILS Oy will design the vessel and prepare the technical documents needed to hold tender for its construction in compliance with the performance requirements for the vessel, and will assist the Finnish Transport Agency in negotiations with shipyards later this autumn. The government has already taken earlier a decision in principle to procure a new icebreaker; and 125 million euro has been earmarked for its construction by winter 2016.
