Mobile Offshore Unit (MOU) Stability Course

Objectives:

Course provides comprehensive training for personnel who will be involved in Ballast Control operations and going to obtain license of OIM or Barge Supervisor. Course will provide an understanding of the response of drill ships, column stabilized floating units as well as jack up rigs while afloat, to loading and environmental forces and damage control. After successful completion of the course the trainees should have a better understanding in the theory and practical application of ship stability, particularly the stability of a mobile offshore unit (MOU) and ballast control procedures for trim and list, use of information provided in the rigs operational manual for safe operations of the MOU.
