- Abstract
- In this study, a numerical analysis was performed on hand-over between laying vessel and FPSO with truncation modeling. The installation vessel is located close to FPSO in order to hand over the flexible riser. The weight of a riser is divided into A&R (Abandonment & Recovery) winch and PIW (Pull-in Wire) according to the wire payout length. The tensions of an A&R winch wire and a PIW wire were reviewed based on the limitation criteria. A truncation modeling was considered to apply the model tests at Ocean Engineering Basin of KRISO. The anchor point and the water depth were revised considering pit diameter and basin depth. The top tensions of the wires were investigated under various wave headings, height and periods in wave conditions. The discussion is made on the effects of the load transfer condition, wave headings. Copyright ？ 2018 by the International Society of Offshore and Polar Engineers
