The largest Spanish-flagged LNG carrier, about to enter into service

In early 2018, Endesa entrusted the Norwegian shipping company Knutsen OAS Shipping with the construction in South Korea of the first generation LNG Carrier (with a capacity of 180,000 cubic meters) for the transport of liquefied natural gas.

Thus, at the beginning of 2018, the construction of the first methane tanker, "Adriano Knutsen", began for the transport of LNG (Liquefied Natural Gas), which  and will be completed next month. of July. 

She is a third-generation methane tanker with total on-board refueling system, owned by the Norwegian shipping company Knutsen Oas Shipping, which is being built at the Hyundai Heavy Industries (HHI) shipyard, the largest shipyard in the world, located in Ulsan, South Korea.

"Adriano Knutsen", the largest Spanish-flagged ship, will have a capacity of 180,000 cubic meters of LNG (about 72 Olympic swimming pools), the one-day equivalent demand of LNG of all Spain, or in other words, the average annual supply of a city of 170,000 homes.

Pending final surveys and the completion of sea trials prior to delivery, which will begin in April. The ship is almost built and will be chartered by Endesa in the summer of 2019. She will be initially deployed for the transport of LNG supplied to Endesa by Corpus Christi Liquefaction LLC (Cheniere Energy Group). The contract foresees the sale of 2 mcm/y (two million cubic meters per year) for the next 20 years. In one year, "Adriano Knutsen" will be able to make 12 trips in the transatlantig route or 6 transoceanic trips to the Pacific from Corpus Christi.

The total reliquefaction system on board allows to reduce consumption and choose the fuel for its propulsion, which can be 100% natural gas or low sulphur fuel-oil, which makes it much cleaner in emissions than most ships that use heavy fuel oil, significantly reducing them. Likewise, the ship has systems for the reduction of NOx emissions.

There is good news for Spanish seafarers, since the crew will be composed of 26 people: 11 officers (Spanish) and 13 seamen, plus two cadet officers.

The tendency to suppress the most polluting coal plants will increase the demand for natural gas as cleaner fuel for the production of electricity (in addition to other sources of generation such as nuclear power), giving firmness to the system and allowing the progressive penetration of renewable energies towards a zero emissions scenario in 2050.

For the transportation of gas by Enel group, "Adriano" will  be followed by new constructions, given the economic advantages and purchase volumes of LNG contracted for the coming years. At present, the construction of a twin ship, the "Traiano Knutsen" has just started in the same Ulsan shipyard with an expected delivery to Enel in mid-2020.
