Coral Energy - LNG carrier

LNG carrier Coral Energy is the world's first direct driven dual-fuel ice-class 1A LNG carrier.

One of the innovations applied on the vessel is the direct drive dual-fuel engine.

This unique engine means that the propulsion system is extremely efficient and, with LNG or bio-LNG as maritime fuel, the propulsion provides an eco-friendly ship operation.

Due to her size and in-house developed innovative compatibility package, the ship is able to load LNG at large scale terminals.

Coral EnergICE – LNG carrier

Coral EnergICE is the first LNG carrier holding the Ice Class 1A Super. She is specially designed and constructed to operate in the Baltic Sea in order to bring Liquefied Natural Gas (LNG) to Gasum’s terminal in Pori and Manga LNG terminal in Tornio, Finland. The naming ceremony of Coral EnergICE was held in 2018 in Turku, Finland.

The vessel’s hull is reinforced to break through one-meter thick ice with the engines and generators designed to give the vessel extra power when sailing through thick ice and harsh winter conditions.

Furthermore, this state-of-the art vessel is equipped with a dual fuel engine. It uses LNG boil-off gas as a fuel for its main and auxiliary engines, making the vessel fully compliant with future emission regulations.

Kairos - LNG bunker

Kairos is one of the larger dedicated LNG bunker supply vessels in the world. The 7,500 m³ vessel is equipped with a dual-fuel engine using LNG as main fuel and is equipped with a range of technical features to be able to serve a wide range of maritime customers and storage terminals.

The ship has been designed to supply LNG to various types and sizes of vessels at all possible bunkering locations in Northwest Europe, including ports and anchorage areas at the North Sea and Baltic Sea.

As a part of that set-up the vessel can supply LNG with a transfer rate from 60 m³/ hour up to 1,250 m³/ hour.

The ship’s cranes have a range of up to 30 meters, which enables the vessel to serve even the largest customers in the market. Kairos is able to operate under harsh weather conditions and at high sea, due to the vessel being DP2 certified and being build with the ice class 1A. Vapour return gas received from customers can be stored in a separate CNG tank on board.

Seagas - LNG bunker

Seagas was retrofitted from car ferry to LNG fuelling vessel in 2012 at Fiskerstrand verft, Norway. She was specially built for ship-to-ship refuelling. The vessel can supply LNG driven vessels with up to 160 m3 LNG in about 45 minutes.

Seagas was the first of its kind in the world and is classified according to the same regulations as for ocean-going LNG tankers.

On a daily basis Seagas delivers between 60-70 ton LNG to the Viking Line cruise ships M/S Viking Grace and M/S Viking Glory.

With Seagas’ safe LNG bunker solution we meet Viking Line’s needs for efficient bunkering including the highest safety standard as both are important in this context.
