The new Norwegian semisubmersible regulations are discussed. The Norwegian Maritime Directorate (NMD) requires that existing accommodation rigs have stability, mooring, emergency power generation, and lifesaving appliances upgraded by 1985. Drilling rigs in service must also be upgraded, but as yet, the NMD has not made up its mind what damage stability criteria to apply. Rigs that meet the NMD are discussed, as well as the projected costs of the implementation of the regulation. (JMT)
