heal.abstract Motivated by significant findings of a recent Formal Safety Assessment (FSA) on large oil tankers recently submitted to IMO, the need to develop more efficient ship designs from fuel consumption and CO2-emissions point of view and the high risk related to the accidental oil pollution, GL completed a novel Aframax tanker design concept which offers high cargo capacity, low oil outflow index, low fuel consumption and EEDI and best in class cost of transport. A multi-objective optimisation was established focusing on minimising propulsion power, minimising oil outflow in accidents and maximising cargo volume. A large number of design variants were tested before a competitive design solution emerged which offered the desired properties. The optimisation environment FRIENDSHIP-Framework linked potential and viscous flow codes, to compute propulsion power, with NAPA, to compute oil outflow index, stability and trim, and POSEIDON, to assess the hull scantlings according to IACS CSR's prescriptive part. The resulting design documents that multi-objective optimisation can effectively be used to investigate many more design variants than in traditional design activities. Therefore, the result of this joint project offers potential benefits for ship owners and ship yards. © 2011: The Royal Institution of Naval Architects. en
