Abstract: The steady depletion of land resources and abundance of natural resources, renewable as well as non-renewable in the high seas have thrusted upon the nations the need to explore as well as protect its interest areas in the oceans. Toward facilitation of the same, aircraft on a floating platform plays a pivotal role and has reassumed prime importance as the epicenter of aviation operations from deck at sea. The limited space availability, ~ 180 m in contrast to ~ 1800 m of stationary ground on the land coupled with ship motions, makes landing on a floating platform as the most challenging part of an aviation operation onboard. View foregoing, there is an invariable augmentation in the pilot workload which is supplemented by various turbulent regions of flow arising out of the interactions of fluid with the bluff body structures of the ship as well as various structures placed on topdeck. These effects termed ‘burble’ are more pronounced within the last half mile of the landing approach. This study is aimed toward facilitating reduced pilot workload and turbulences on the landing approach by splitting the single superstructure on the topdeck into two distinct superstructures and positioning them apart from each other longitudinally. The model used in the study is a generic aircraft carrier (GAC) and URANS is used for the computational investigation of the subject problem. Post investigation, it has been observed that by the way of the subject approach, there is a ~ 35% reduction in turbulence along the approach line behind the island.
