DESIGN OF A COMPACT HIGH-PERFORMANCE PIPELAYING/CRANE SHIP FOR SERVICE IN AREAS WITH AVERAGE SEA CONDITIONS

The Authors discusses the merits of the combined pipelayer/crane-ship as compared with the pipelayer and the crane-ship, enumerates the important factors in the design of the single-purpose vessels, and points out the compromises necessary in the design of a combined pipelaying and crane ship. The uncertainty of future charter rates and market conditions calls for a "good nose", as well as technical knowledge, on the part of the operator when deciding what type of vessel to build. Blohm + Voss have gained experience in these matters from building the semi-submersible lay-barge Choctaw II the combined pipelayer/crane-ships ETPM 1601 and DLB 1602 Sea Troll and the crane-ship Astrakran. The article includes brief information, with photographs, on these vessels and on the Viking Piper. A table is given showing, in general terms, the type of pipelayer, crane-ship, or combination vessel suitable for different sea conditions. This is followed by a description of a proposed design for a self-propelled pipelayer-crane-ship, giving high performance and suitable for average sea conditions (these two terms are defined).
