In the years before the register was established, the Norwegian register lost out as it could not compete with lower-cost registers. The main objectives of establishing the register were: • Maintain the shipping industry under the

United Nations (UN),
International Maritime Organization (IMO) and
International Labour Organization (ILO)). • Maintain a Norwegian fleet that could give greater employment opportunities to Norwegian seaman than a foreign-flagged fleet. • Restrict the types of vessel that may be registered. • Limit the trading areas allowed. NIS vessels cannot trade cargo between Norwegian ports or carry passengers on a regular basis to or from Norwegian ports. The register has been highly successful and in 2002 there were 880 vessels in the register with a total of around (). == Criticism ==
