COURSE OVERVIEW:

The process of moving a jack-up rig and executing jacking operations is a critical phase in offshore drilling that requires precise coordination between marine and drilling crews. This course provides a fundamental understanding of the mechanics involved in lifting the hull above the sea surface and the stability requirements during the transition from a floating to an elevated mode. It covers the essential components of jacking systems, including the rack and pinion mechanisms and the hydraulic systems that facilitate movement.

Participants will explore the logistical challenges of rig moves, including the mobilization of towing vessels and the navigational risks associated with relocating massive structures in various sea states. The scope encompasses an analysis of seabed interactions, including spudcan penetration and the risks associated with punch-through incidents. By understanding the environmental limits and the structural constraints of the rig, personnel can ensure that the relocation process is conducted without compromising the integrity of the vessel or the safety of the crew.

The coverage also extends to the documentation and regulatory requirements governing offshore rig moves. This includes the preparation of move plans, weather window analysis, and the roles of the Offshore Installation Manager (OIM) and the Barge Master. By the end of this course, participants will have a comprehensive foundation in the operational steps required to safely position a jack-up rig, from initial seafastening to final leg penetration and hull leveling.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Describe the primary components and functions of a jack-up rig jacking system.
• Explain the stability criteria for a jack-up rig in both floating and elevated conditions.
• Identify the key steps involved in preparing a rig for a tow or relocation.
• Analyze seabed soil reports to predict spudcan penetration depths.
• Execute pre-loading operations to ensure the structural stability of the legs.
• Recognize the warning signs of a potential "punch-through" during jacking.
• Coordinate effectively with tugboat captains during rig positioning and anchoring.
• Apply safety protocols for seafastening drilling equipment prior to rig moves.
• Calculate the environmental limits for jacking operations based on wave height and wind speed.
• Monitor the leg load sensors to ensure even weight distribution during elevation.
• Conduct a thorough risk assessment for rig move operations in challenging environments.
• Perform emergency procedures for jacking system failures or power loss.
• Document rig move activities in compliance with international maritime and industry standards.
