Finland’s defense capabilities are set to be enhanced with the selection of Aker Arctic for the provision of the ARC ILMS ice load monitoring system. This cutting-edge technology will be integrated into the Finnish Navy’s Pohjanmaa-class multi-role corvettes, a critical addition designed to measure the structural loads of ships as they navigate through ice-covered waters. The system is engineered to deliver real-time feedback to operators, thereby ensuring enhanced navigational safety and operational effectiveness in harsh environments.
Aker Arctic is no stranger to the Pohjanmaa project. The company has already contributed to the initiative with various components, including ice-strengthened controllable pitch propellers, pitch control mechanisms, propeller shafts, and shaft seals. Furthermore, Aker Arctic is tasked with the comprehensive design, material delivery, and installation supervision of the entire propulsion system for the corvettes.
The ARC ILMS ice load monitoring system is pivotal for achieving operational efficiency. By continuously monitoring ice loads, the system aids in improving the propulsion efficiency of the vessels, which in turn leads to reduced fuel consumption and optimized maintenance schedules. It operates by collecting data from strain sensors to provide a real-time display of ice loads, and it utilizes sophisticated statistical analysis to forecast future conditions. The package includes a robust software platform equipped with forecasting algorithms, sensor location analysis, and seasonal data evaluations. Accurate assessments generated by the ARC ILMS support the safe navigation of the corvettes, empowering crews to make informed and strategic decisions in demanding conditions.
Construction of the first of the Pohjanmaa-class corvettes commenced last year, with an ambitious timeline that anticipates four vessels entering service by 2029. Designed to be integral to Finland’s Defense Forces, these corvettes are expected to remain operational until the 2050s. Their multifunctional capabilities will allow them to support a variety of missions, including preventing attacks, laying naval mines, and conducting underwater warfare.
Each corvette in this class will accommodate a crew of approximately 70 personnel and is expected to achieve a top speed exceeding 26 knots (48 kilometers or 30 miles per hour). In terms of armament, the vessels will be outfitted with advanced surface-to-surface missile systems and surface-to-air missile systems. They will also feature naval guns, decoy systems, and sophisticated electronic warfare suites, ensuring they are equipped to meet contemporary naval challenges.
The development of the Pohjanmaa-class corvettes, underscored by Aker Arctic’s innovative contributions, marks a significant advancement for Finland’s naval forces in ensuring security and operational readiness in the face of evolving maritime threats.
