Hyundai Heavy Industries (HHI), the world’s largest shipbuilder, announced it received the second approval in principle (AIP) from DNV GL for SkyBench, a design for maximizing cargo loading capacity of large containerships. The classification society verifies the strength and structural analysis including the overall finite element analysis conforming to S11A rule, a partial ship analysis, an overall hatch corner’s relative deformation check, a spot fatigue check for several critical hatch corner locations, and a detailed analysis of the design with a solid model for the parking device. The first AIP HHI received in June last year at the Nor-Shipping exhibition in Oslo was its confirmation of the concept design of SkyBench.
