New Ice Class LNG Tankers Get Novel Bridge Controls for the Harshest of Environments

Reversing a Ship Through the Floes Just Got a Whole Lot Easier

FINLAND – SOUTH KOREA – RUSSIA – The Arctic LNG-2 project intends to produce, store and ship 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 a capacity of 6.6 million tonnes per year, as well as stable gas condensate. The total capacity of three lines is therefore projected to be 19.8 million tonnes of LNG per year overall.

To support the project Samsung Heavy Industries has been tasked with the construction of five ice breaking LNG-fuelled tankers. The shipyard in turn has ordered the all-important bridge systems installations from technology group Wärtsilä Voyage, designed in a particular configuration.

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, thus ensuring safe vessels navigation under adverse climate conditions of the Arctics.

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. Similar sets of equipment were installed on gas-carriers built under the ‘Yamal LNG’ project during 2014-2018, where the Christophe de Margerie was the lead ship in the series, prompting Igor Gapeshko, Managing Director of Transas Navigator product line within Wärtsilä Voyage, to comment:

“I’m sure that our experience in Yamal-LNG project, along with the high professionalism of South Korean shipbuilders, and the advantages of integrated technologies, will make the LNG tankers under construction truly effective for solving urgent tasks and developing safe navigation in the Arctics.”

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.

Samsung has much experience in working on vessels designed for these testing conditions. Amongst others, it has developed and built the world's first Arctic shuttle tanker, Liquefied Natural Gas Floating Production Storage and Offloading units (LNG FPSOs) and developed and constructed various Arctic icebreakers and container ships.
