MARPOL Annex VI regulations 14 and 4 generally apply in Norwegian waters, which are partly in the North Sea Emission Control Area. However, Norway is also party to the European Economic Area (EEA) agreement, which brings together the 28 EU member states and three non-member states, including Norway and Iceland in an internal market governed by the same basic rules. As such some parts of Norway’s legislation are in line with EU Single Market legislation.

Key points of the European Union sulphur directive are therefore reflected by the Norwegian Maritime Authority Regulations of 30 May 2012 No. 488 on environmental safety for ships and mobile offshore units.

The regulations are wide ranging. Sections 12, 13 and 14 are relevant to sulphur oxide control. In particular:

  • The sulphur content of fuel oil used on board while a ship is securely moored at berth or at anchor in port for more than 2 hours shall not exceed 0.10% m/m.
  • Outside emission control areas, the sulphur content of the fuel shall not exceed 1.50% m/m for passenger ships on a regular service to and from ports within the EEA and which are in Norwegian territorial waters or in the Norwegian economic zone.

While EGCS is permitted as alternative means of compliance, Norway has specific rules for 2 areas designated as World Heritage Fjords where additional controls apply:

Ships must use either:

a) fuel with a sulphur content not exceeding 0.10% by weight; or
b) an approved closed loop exhaust gas cleaning system; or
c) an approved hybrid exhaust gas cleaning system in closed loop mode.

Ships using an exhaust gas cleaning system to meet the sulphur requirement are required to use a device for reducing visible emissions to air.

Coordinates for the World Heritage Fjords are given in Regulations No. 488 Section 10a, relating to sewage and grey water.
