The »Christophe de Margerie«, the world’s first icebreaking LNG tanker, has been christened in St. Petersburg on 3 June 2017. The event was held in Port Bronka.

The 299 m long tanker has been built on order for SCF Group to provide year-round transportation for LNG in the difficu[ds_preview]lt ice conditions of the Kara Sea and Gulf of Ob (Yamal LNG project). The »Christophe de Margerie« was commissioned by Sovcomflot on 27 March 2017 following her successful ice trials in the Arctic Ocean.

The LNG carrier was named after »Christophe de Margerie«, the former CEO of Total, who had played a key role in developing investment decisions and a technological basis for the Yamal LNG project. He had also made a major contribution to the development of Russo-French economic relations in general. The vessel’s godmother was Valentina Matvienko, Chairperson of the Russian Federation Council.

In terms of specifications, the vessel has no parallels in the world today. She was assigned an ice class Arc7, the highest ice class amongst existing merchant vessels. According to SCF Group the gas carrier is capable of sailing independently through ice up to 2.1 m thick.
The total power of the vessel’s main diesel engines is 64.35 MW. The power of her propulsion system is 45 MW, which is comparable to the capacity of a modern nuclear-powered icebreaker. The tanker is equipped with Azipod thrusters. »Christophe de Margerie« became the world’s first vessel with a high ice-class to have three Azipod units installed.

The thrusters, in combination with other special equipment and mechanisms, ice-breaking bow and a special bridge design, provide a high ice-breaking capability and manoeuvrability, allowing the vessel to move continuously bow forward in ice up to 1.5 m thick, and the use of the stern-first motion (Double Acting Tanker, DAT function) principle, which is required to overcome hummocks and heavy ice fields in high latitudes.
The turning circle of the vessel in 1.7 m thick ice, is 1,760 m – which exceeds the design specification by almost twice SCF Group stated.

»Christophe de Margerie« can sail along the Northern Sea Route westward from Sabetta all-the-year round and eastward for six months of the year (from July to December). Previously, the summer navigation window on the Northern Sea Route was limited to only four months with ice-breaker support.

The tanker was designed in accordance with the requirements of the Polar Code and is notable for her high energy efficiency and complies with high environmental standards. Along with traditional fuels, the vessel’s propulsion system can use LNG boil-off. Compared with conventional heavy fuel, the use of LNG can significantly reduce the emissions of harmful gases into the atmosphere: sulphur oxides (SOx) reduced by 90 %; nitrogen oxides (NOx) reduced by 80 % and carbon dioxide (CO2) emissions down by 15 %. Such performances are particularly important for a vessel operating in the Arctic environment, which is highly sensitive to external factors.

The ice-passing and manoeuvring qualities of the new tanker were fully confirmed by her ice trials, which took place from 19 February to 8 March 2017 in the Kara and Laptev Seas, and by her successful maiden call at the gas terminal at Sabetta Port on 28 March 2017.

The tanker’s successful maiden call at Sabetta Port, in terms of winter navigation, was the result of the diligent joint work of Sovcomflot, Novatek and Yamal LNG, which took about ten years. According to SCF Group a project of such scale and complexity demanded an in-depth development of all the details, with the involvement of the leading scientific research and project organisations both from Russia (Arctic and Antarctic Research Institute, Krylov State Research Centre) and internationally (Aker Arctic Research Centre, Hamburg Ship Model Basin).

The »Christophe de Margerie« is the first vessel in a series of 15 gas carriers planned for the Yamal LNG project.
