Decommissioned platform installations are now being removed from North Sea waters using heavy lifting crane vessels of either monohull or semisubmersible format. Lifting procedures may not be the reverse of installation and uncertainties may arise in respect of actual weight and centroid of the deconstructed units. Technical issues and hazard identification are discussed. Concerns and questions need to be raised and answered satisfactorily at each stage of planning, pre-lift inspection, during detachment, lifting and ultimate disposal. While recent operations have seemingly been successful, a safety regime needs to be assured since platforms due for removal will be of increasing size and new contractors could be drawn into the business.
