Initial registration
Upon initial registration of a mobile offshore unit (newbuilding / change of flag / change of vessel type), the NMA’s Section for Mobile Offshore Units (MOU) and the Department for Ship Registration (NIS/NOR) will be involved in the process.
The unit’s technical and operational safety will be audited by the Section for MOU whilst the Department for Ship Registration will register the unit in NIS or NOR.
To start the process, please send a "Application for certification – Mobile Offshore Unit " to post@sdir.no. You will then be invited to an initial meeting with the Section for MOU. A Norwegian call sign and, if applicable, IMO number will also be allocated upon receipt of the notification of newbuilding.
The Section for MOU will request documentation to be submitted according to its Document list (see bottom of this page). Additionally, the Department of Ship Registration has its own checklist for documentation requirements either for New registration of a mobile offshore unit in the NOR or for New registration in the NIS.
Please do not hesitate to contact us should you have any questions.
