This paper investigates the line dynamic forces connecting tugs and a floater, where the planar motion of the floater is due to theweather criteria during the position keeping of the offshore structure by tugs. The analysis situation consists of the position keeping states for theseabed mooring line connection work of the offshore structure atthe offshore site. Specifically, the decision aboutthe tug power capacity for theposition keeping is essential and depends on the weather criteria, line characteristics, length of line, etc. The planar motion of the structure isconstrained by the interference of the installation vessel's operational range, behavior of the underwater fairlead, and other surrounding structures. In this paper, the tug line forces and planar motion of an offshore structure are summarized dependent on the tug line length and line materialcharacteristics in the states fora given floater draft and weather criteria. The tug line dynamic forces and planar motion evaluated here will be usedto determine the proper tug power and clearance of an offshore structure.
Abstract
This paper investigates the line dynamic forces connecting tugs and a floater, where the planar motion of the floater is due to theweather criteria during the position keeping of the offshore structure by tugs. The analysis situation consists of the position keeping states for theseabed mooring line connection work of the offshore structure atthe offshore site. Specifically, the decision aboutthe tug power capacity for theposition keeping is essential and depends on the weather criteria, line characteristics, length of line, etc. The planar motion of the structure isconstrained by the interference of the installation vessel's operational range, behavior of the underwater fairlead, and other surrounding structures. In this paper, the tug line forces and planar motion of an offshore structure are summarized dependent on the tug line length and line materialcharacteristics in the states fora given floater draft and weather criteria. The tug line dynamic forces and planar motion evaluated here will be usedto determine the proper tug power and clearance of an offshore structure.
