The Troll Oil Pipeline - TOR - is a dedicated pipeline for transportation of oil from the Troll field to the onshore terminal at Mongstad on the west coast of Norway. When installed, TOR will be the first pipeline installed in a deep Norwegian fjord, namely Fensfjorden. The water depth ranges from about 250 m at the sill down to about 500 m at the deepest part. The maximum depth is 540 m and is located just inside of the sill. The entrance to the Fensfjord consists of a deep canyon in the Norwegian Trench leading into a sill just northwest of Holmengra. From the sill depth down to the maximum depth, the pipeline route follows a steep ravine through an area of rough and rocky sea bed. Current measurements have revealed higher current velocities than expected in this area. These currents were concluded to be due to heavy water occasionally overflowing the sill and into the fjord. In the present paper, the extensive measurement programme, including 27 current meters in operation up to 16 months, is described including aspects of the data analysis. In conjunction with the measurements, also laboratory and numerical modelling studies were performed and the results from these are presented. A comparison of measurements and model results are also presented.
