Norske Hydro has successfully developed and tested a diverless pull-in and connection system for the Troll Oseberg gas injection project (Togi) in the North Sea. This paper describes the system which has proven to be fast, efficient and reversible, at any sequence of pipe connecting operations. The Togi project involved installation of five subsea gas wells at 1,000-ft water depths. Subsea wells were drilled through a six-slot template which serves as a foundation for the gas manifold, a 20-in. gas line, and a pipe bundle carrying hydraulic fluid, methanol and electric distribution systems.
