According to a recent publication by Aker Arctic, the Finnish engineering firm has introduced its latest design for a B+ class icebreaker intended for the Finnish Transport Infrastructure Agency. This cutting-edge vessel comes at a time when there is an increasing global demand for ships capable of navigating icy waters.
This new addition is part of Finland’s ongoing initiative to modernize its state-owned icebreaking fleet, focusing on meeting stringent environmental regulations while ensuring consistent access to Baltic Sea ports throughout the year.
The B+ class promises improved efficiency and reduced emissions compared to current medium-class models, all while being more cost-effective than larger A-class icebreakers. Aker Arctic stands out as a leader in icebreaking technology and has previously designed vessels that operate globally. While this particular model caters specifically to Finland’s needs, it also holds potential appeal for international clients facing similar challenges in the evolving Arctic landscape.
In North America, both the U.S. and Canada are actively working on expanding their fleets of icebreakers. The U.S. Coast Guard is expected to make significant design decisions soon regarding their future vessels. Recently, Aker joined forces with American Bollinger Shipyards and Canadian Seaspan Shipyards in a consortium aimed at developing next-generation icebreakers for the Coast Guard.
Meanwhile, another consortium led by Canada’s Davie shipyard is competing for contracts as well; they recently announced plans for an ambitious $1 billion facility dedicated to building icebreakers in Texas.
Aker has now entered phase two of its project after completing initial designs earlier this summer; they are currently conducting model tests both in open water and within icy conditions. “Model-scale testing remains essential,” explains Tuomas Romu, chief designer at Aker Arctic. “It helps us understand how our unique designs will perform once operational.”
While standard metrics can assess basic performance capabilities, complex maneuvers—like breaking free from an encased channel—pose greater challenges that require specialized testing teams equipped with small test vessels.
The company’s integrated testing facility allows seamless collaboration between naval architects and engineers during these trials—a setup that encourages innovation without barriers. Interestingly enough, some tests related to the new B+ class were open to public observation—a rare opportunity given most projects remain confidential—allowing visitors insight into how effectively models break through thick layers of ice.
Aiming high with this medium-class vessel design dubbed “no compromise,” Aker focuses not just on creating powerful machines but rather versatile ships capable of adapting over their 50-year lifespan amidst changing sea conditions.
“Instead of maximizing thickness capabilities,” Romu clarifies, “we prioritize seakeeping performance and adaptability within heavily deformed pack ice.”
The company plans to finalize tender materials by year-end 2023 with shipyard selection slated for 2026; delivery of this innovative B+ class vessel is anticipated by late 2029 as Finland continues its rapid advancements in maritime technology.
