The Ministry of Social Affairs asked advice from Nogepa, IRO, PriceWaterhouseCoopers (PWC) and the Unions on the plans to introduce compulsory social insurance for every one working on the Dutch Continental Shelf. PWC made a paper listing all the possible problems that might arise by introducing social security changes on the NCP. The law came into effect on the 23rd December 2010. All employees who are working on the Dutch part of the continental shelf will be mandatory covered by national insurance, health insurance and employee insurance scheme. With the introduction of this law foreign employees working on the Dutch continental shelf who do not live in the Netherlands will be covered by Dutch social security legislation the same way as foreign employees who work in the Netherlands but do not live in the Netherlands irrelevant of the duration of the work period on the continental shelf.
