In 2002 further innovations were made and patented by Kvaerner Masa-Yards: We integrated the tank cover structure into hull longitudinal strength. Following this a spherical lank LNG Carrier was redesigned and remarkable improvements were achieved Elimination of all negative consequences that result from typical large deck openings of spherical tanks Excellent stiffness of hull Improved hull form 10 % lower propulsion power with any type of machinery Significantly reduced construction costs Improved maintenance aspects Lowest operational cost Even larger size LNG Carriers are now more feasible because of this new concept. New concept allows for larger ships: Lower freeboard and cargo manifold location Omission of extremely thick steel plates Always stiff and light construction regardless of size
