The objective of this course is to familiarize with basic stability theory in reference to Mobile Offshore Units and to become proficient in applying stability calculation for MOU in order to maintain its safe condition in both the intact and damage stability condition as per MODU Code 2010 and Norwegian Maritime Authority Regulations.

Delivery: classroom


Course contents

Knowledge, experience and competence in each of the following matters is considered necessary for the proper performance of the essential safety and pollution prevention functions assigned to the Ballast Control Operator on column-stabilized MOUs.



1. Basic Stability:


  • understanding of general stability terms
  • theory of moments applied to stability including the effects of heavy lifts
  • understanding of the inclining experiment report and its use
  • effect of free surface on stability
  • use of hydrostatic curves, deadweight scale and hydrostatic tables;
  • use of cross curves to produce a curve of static stability and information from curve;
  • dynamic stability; synchronous rolling and angle of loll; stability criteria for MOUs;
  • effect of mooring system on stability
  • effect of Dynamic Positioning System on stability
  • daily loading calculations.

2.  Applied Stability - application of stability knowledge in calculation:


  • deck loads and effect on stability
  • examination of ballasting systems and procedures;
  • response to systems failures including station-keeping systems, damage to structures and subsequent action;
  • damage control procedure, watertight compartments counter-flooding, use of pumping systems
  • environmental conditions and their effect on stability;
  • unit and environmental limitations and criteria for changing to survival condition;
  • zones of reduced stability, precautions to take
  • emergency procedures.



Course Prerequisites

Participant shall hold at least a STCW Certificate of Competency of OOW and have valid following certification:


  • Medical Certificate
  • Personal Survival Techniques. (A-VI/1-1)
  • Minimum standard in competence in fire-fighting. (1-2)
  • Elementary first aid. (1-3)
  • Personal Safety and Social Responsibilities. (1-4)
  • Hold a proficiency in survival craft
