U.S. COAST GUARD APPROVED
“SURFACE UNIT AND TLP STABILITY"

Martin International’s five-day approved course is designed to meet regulatory requirements for obtaining the Offshore Installation Manager, Barge Supervisor and Ballast Control Operator licenses restricted to Tension Leg Platform Units licenses.

The “Surface Units & TLP Stability” course will introduce the student to stability theory, the effect of weight on stability and trim, mathematical calculations, load form usage, ballast control procedures for trim and list and use of information provided in the rig’s operations manual for safe operation of the unit. A “Worst Case Scenario” concerning an actual offshore disaster is used in conjunction with Damage Stability and Survival Mode Preparations to illustrate proper procedures in emergency situations.

Upon successful completion of the course, students will be able to demonstrate how the addition, discharge or shift of weight affects the overall stability of the rig. The student will also demonstrate proficiency in calculation of load forms by finding new center of gravity (KG, LCG and TCG) locations, vertical, longitudinal and transverse moments, free surface corrections, corrected KG, maximum allowable KG, new displacement and new draft after the addition or discharge of weight.

An Operation Manual for a semi-submersible drilling rig introduces the student to unique stability requirements for rig. For example, understanding the mooring system and how its anchors and mooring tensions affect the rig’s load form calcu­lations is important to understanding the overall stability of a semi.

The Surface Unit & TLP Stability course covers the fundamentals needed to develop a basic understanding of TLP principles (determine the proper tendon tension, operating mode, platform location and environmental conditions). This is followed by a method to determine the effect of a loading change (added, discharged or transferred weights) on the tension of each tendon and how ballast or other loads may be adjusted so that the actual tendon tension agree with the proper values.

Our staff of Instructors combines years of teaching with practical experience and includes USCG licensed Offshore Instal­lation Managers and Barge Supervisors. Anyone pursuing a TLP license and wishing to satisfy the Stability require­ment, persons who wish to take a “refresher” stability course or anyone who has a personal desire to learn something about Stability is welcome to attend our course. Martin International’s Surface Unit & TLP Stability Course has something for everyone.
