This article discusses the mechanics of the behavior of flowlines in a J-tube during pull-in and the theoretical models available to forecast the pull-in forces. The test program did not pretend to develop general design guidelines, but concentrated on the Troll field conditions only. The results may, however, be applicable to the design of J-tubes and flowline risers for a range of different conditions. Practical aspects with regard to J-tube connections are discussed, a design for the riser hang-off and the bellmouth sealing is presented, and the proposed method of tie-in operation is described.
