Paper Number: SNAME-TOS-2021-24
... with and without side hulls in headsea regular waves respectively. The primary objective was to evaluate its accuracy of predicting seakeeping performance of the Tri-SWACH under regular headsea waves in AEGIR. A series of simulated time domain heave and pitch responses for Tri-SWACH with and without side hulls via...

... and Marine Engineers Copyright 2020, The Society of Naval Architects and Marine Engineers ABSTRACT A Ship-shaped FPSO is one of most popular hull forms in oil and gas industry. The only alternative hull in operations with minor market shares is the cylindrical FPSO hull. In order to add contractual options...

Paper Number: SNAME-TOS-2019-008
... For many offshore developments, there is a drive to minimize the required manning and enabling remote operations to reduce personnel exposure and to reduce the overall cost (lighter topsides, simpler hull, less maintenance). This paper considers semisubmersible production facilities...

Paper Number: SNAME-TOS-2018-026
... During coming off location operations for jackups (the transition from the elevated mode to the afloat and then the transit mode), the hull is jacked down into the water to obtain a buoyancy force great enough to retrieve the legs. In locations with soft clays, leg penetrations in excess of 15m...
