Since 1961 Single Point Moorings (SPM'S) have been used successfully in nearly all parts of the world. Nevertheless the feasibility of applying a conventional SPM in the North Sea, where sea conditions are very bad, was considered doubtful in 1972. At that time the practical experience with loading hoses at installed SPM's was such that no long hose life was expected at a North Sea SPM location. Consequently several oil companies developed much more complicated SPM systems such as ALP, ELSBM, SPAR etc. These mooring systems include facilities to keep floating hoses out of the water and to restrict submarine hose motion. Moreover, helicopter landing facilities are available to improve accessibility. The design of and operational experience with a typical example of a more advanced SPM the ELSBM, are described in this paper. A performance comparison between a single ELSBM and two conventional SPM's has been made.
