Wärtsilä has been contracted to deliver a complete bridge systems installation for five ice breaking dual-fuel LNG carriers under construction at Samsung Heavy Industries’ shipbuilding complex in South Korea. The vessels are destined for operation in connection with the Arctic LNG-2 project.

The navigational systems are delivered by Wärtsilä Voyage, the new business responsible for digital solutions and decision support tools to enhance safety and reliability of shipping operations.

The order with Wärtsilä Voyage – a new business unit responsible for supplying digital solutions and decision support tools – was placed in the first quarter of 2020 and is now being fulfilled.

Under the contract, two equivalent bridges will be placed in vessels’ superstructure; one of them is turned 180 degrees from the conventional position. This peculiar construction will allow icebreakers to move both forward and aft, ensuring safe navigation under Arctic climate conditions.

Both navigation bridges of all five LNG tankers will be equipped with the Multifunction Display system consisting of 12 multifunction workstations with a full set of basic applications, including ECDIS, Radar, Conning navigation information display system, BAMS alarm tracking system, and Navi-Planner for advanced route planning. The scope of Wärtsilä solutions also includes VSAT and IRIDIUM satellite communication systems. The workstations are fully integrated into a unified system, which allows the main operational functions to be duplicated, thereby improving safety of ice navigation.

All the equipment installed on board is fully compliant with the requirements of the Russian Maritime Register of Shipping (RS) and Bureau Veritas (BV). It is designed and tested to operate all year-round in heavy Arctic conditions at temperatures down to 52°C below zero. The installation of the equipment is scheduled for 2020-2023.

The Arctic LNG-2 project is dedicated to production, storage and shipment of liquefied natural gas (LNG) and gas condensate from the Salmanovsky gas field of the Gydan Peninsula. The project involves the construction of three LNG production lines with an annual capacity of 6.6 million tons, as well as stable gas condensate. The annual production capacity of the three lines is projected to reach 19.8 million tons.
