Neil Duffin, president of ExxonMobil Development, said, “The Q-Max carrier has broken the LNG transportation routine in almost every way. Our technical strength has driven us to develop new LNG vessels and is driving the LNG value chain. Innovation."
These large LNG ship technologies were developed in partnership with Qatar Petroleum and include a number of industry breakthroughs and major improvements such as larger ship sizes, shipborne reliquefaction units, low speed diesel engines, twin rudders Propellers, the largest ship-borne LNG tanks ever built, state-of-the-art hull anti-fouling protection and a more complete fire protection system. The end result of these new generation ships is to reduce transportation costs by 20-30%.
Mr. Faisal Al Suwaidi, CEO of Qatargas, said, “Qatar Petroleum and ExxonMobil hosted a major technical effort to make this breakthrough in the LNG transportation industry. North Field in Qatar is The world's largest non-associated gas field, with recoverable reserves of more than 900 trillion cubic feet. Our LNG value chain starts from the northern gas field and extends to households in Asia, Europe, and the Americas, and transportation is a key link. Our innovative technology has effectively transformed the way the LNG business operates, opening up a broader global market for Qatar LNG.†Qatar Petroleum and ExxonMobil are shareholders of the Qatar joint venture Qatargas. Qatargas will lease the Mozah and five other Q-Max vessels to transport LNG produced in the new liquefaction line in Qatar.
For more than 30 years, the size of LNG carriers has remained essentially the same, with a loading capacity of approximately 140,000 cubic meters. Qatar Petroleum and ExxonMobil's ship operators, fluid dynamics experts, ship designers and structural engineers work closely together to develop and rigorously test larger Q-Max tank designs. They conducted a comprehensive assessment of the sloshing of the cargo to verify that the larger system is feasible and reliable. The Q-Max ship, which was eventually developed, is longer than three football fields, from the keel to the dome, and is equipped with the largest membrane storage tank ever built. With a total capacity of 266,000 cubic meters per boat, the natural gas transport capacity of a ship is sufficient to meet the annual energy needs of 70,000 households in the United States.
In addition to increasing the size of the ship, they also undertake an important task to design, test and implement a shipborne reliquefaction plant. The device is capable of reliquefying the natural gas evaporated during transport and then reinjecting it back into the gas tank instead of using the vaporized gas to power the tanker, thus providing 100% full delivery. This is especially beneficial for long-haul voyages from Qatar to Europe and the Americas. With the onboard reliquefaction plant, LNG vessels have the opportunity to switch to more efficient low-speed diesel engines instead of using traditional LNG vessels for steam-powered steam boilers and turbines. The Q-Max is equipped with two diesel engines for driving double-rudder twin propellers. This will improve the ship's energy efficiency, making the ship more reliable and easier to maneuver, reducing fuel consumption by up to one-third.
ExxonMobil's joint venture in Qatar is recognized by industry veterans as a leading company in LNG production and technology innovation, and more industry firsts will emerge in the next 18 months. In addition to pioneering the industry's largest shipping vessel to transport LNG to the market, ExxonMobil is also working with Qatar Petroleum to build the world's four largest LNG production facilities in Qatar and participate in Italy and the UK. , the US LNG regasification terminal project.
