In Arctic waters efficient loading of oil to a tanker is a challenge. At present the experience is meagre compared to approach and mooring of large open water tankers to offshore platforms. Most relevant loading experience is from small vessels moored in the lee of the arctic offshore platforms. With ice present the ice movement causes additional loads on the tanker. The paper presents the major results from a number of model-scale tests with a subsea loading system performed in the Hamburgische Schiffbau-Versuchsanstalt GmbH (HSVA) ice tank in Hamburg. The modelled ship had a conventional ice-breaking bow and a length between perpendiculars of 235 m. The testing was performed at a scale of 1:36 with physical environmental parameters from the Eastern Barents Sea in mind.
