Kongsberg to Supply SS1221 Sonars for Norwegian Coast Guard Vessels

Kongsberg Maritime has signed a contract with Vard to supply SS1221 sonars for the Norwegian Coast Guard P6615 Arctic Coast Guard Vessels.

The three new P6615 Arctic Coast Guard Vessels, which are planned for launch between 2022 and 2024, will replace the Coast Guard’s existing Nordkapp-class offshore patrol vessels.

Under the contract, Kongsberg will equip the new 136-metre, ice-strengthened vessels with its SS1221 sonars, which boast acoustic properties which make them ideally suited for multiple operations safeguarding Norwegian territorial waters, especially those requiring deployment in shallow-water environments.

The SS1221, principally devised for ASW operations and capable of detecting torpedoes or other small objects in the water column, is an active hull-mounted sonar which utilises sophisticated tracking algorithms. Its electronically-stabilised transmitting and receiving beams can be tilted to adjust to challenging sound speed profiles, with its integrated Sound Propagation Model determining the optimal tilt settings and enhancing the Probability of Detection (PoD) ratio. The SS1221 sonars will be delivered to the Coastguard complete with retractable hull units and gate valves for ice protection, ensuring safe and efficient operation.

“We are very pleased to have been selected by the Norwegian Coastguard, and to further strengthen our position as a principal supplier of coastal and shallow-water sonar equipment,” says Thomas H. Dahle, Director of Sales at KONGSBERG. “The Coastguard have to rely upon the most advanced technology available in order to fulfil their responsibilities effectively, and this contract is another resounding testimony to the deep level of trust the KONGSBERG brand has accumulated over our many successful years of trading.”

The Norwegian Government had originally announced plans for the construction of three new coast guard vessels in September 2016. Following review of offers from three competing yards, Vard Langsten was selected to continue negotiations in October 2017. VARD has based its offer on the reference design developed by LMG Marin on behalf of NDMA. The investments were approved by the Norwegian Parliament in the beginning of June 2018, and the final negotiations have been completed and finalized in the following weeks.

The purpose of the new series of vessels is to replace the Nordkapp-class coast guard vessels. The new tailor-made vessels are developed for worldwide operations in all weather and sea conditions, both inshore and offshore.

Specially designed to withstand operations in demanding arctic areas, the new coast guard vessels will have ice-strengthened hull and ice-class notation, and will be built according to the latest requirements for such specialized vessels. With a length of 136 meters and a beam of 22 meters, the vessels feature strong ocean-going capacities for long-distance transits, search-and-rescue operations, surveillance, and oil recovery.

Deliveries of the three vessels are scheduled from Vard Langsten in Norway in 1Q 2022, 1Q 2023 and 1Q 2024 respectively. The hulls will be built at Vard Tulcea in Romania.
