Offshore Loading STL, SAL and OLS

A Comparison Between DP Offshore Loading Operation on Submerged Turret Loading System STL, Submerged Single Anchor Loading System SAL and Offshore Loading System OLS Considering the Hydrometeorological Condition Limits for the Safe Ship’s Operation Offshore

G. Rutkowski

ABSTRACT: The purpose and scope of this paper is to describe the characteristics of and make comparisons between DP Offshore loading operation on Submerged Turret Loading system STL, Single Anchor Loading system SAL and Offshore Loading System OLS considering the hydro meteorological condition limits enabling safe ship’s operation offshore. These systems (STL, SAL & OLS) are designated to operate with specialized DP shuttle tankers, which are equipped with bow loading system (BLS) and optionally also with bottom submerged loading system STL. All above systems are typically used for short term mooring applications offshore associated with the offloading and/or loading of bulk liquid fuel tankers transporting refined and unrefined products of crude oil or liquefied natural gas LNG.
