Jackup Rig Maintenance Project: A Success Story

Our company has successfully completed the challenging Jackup Rig Maintenance project, which showcased our technical expertise, commitment to safety, and ability to deliver exceptional results in demanding offshore environments. The project involved a series of specialized maintenance activities designed to restore and enhance the rig's operational efficiency. Key focus areas included port leg fabrication, crane pedestal maintenance, and cantilever upkeep, all of which were critical to maintaining the rig’s reliability and performance.

Key Aspects of the Jackup Rig Maintenance
  1. Port Leg Fabrication

Port leg fabrication was a pivotal element of this project, requiring precision engineering and seamless coordination. As a core component of the rig’s structural integrity, the maintenance of the port leg was essential to ensure stable and safe operations. The following tasks were carried out:

  • Gusset Plate Replacement: Replaced 140 gusset plates between bays 16 and 36 to reinforce structural integrity and extend the rig's operational life.

  • Ladder Replacement: Replaced 35 meters of ladder across chords K and L, spanning bays 25 to 35, improving accessibility for maintenance and enhancing overall safety.

  • Jetting Line Replacement: Upgraded the jetting lines between bays 0 and 32 in chord I, optimizing system performance and operational efficiency.

  • Anode Installation: Replaced 125 anodes to protect the rig from corrosion and ensure its long-term durability.

  • Removal of Leg Brazing Construction Support Pipes: Removed 3 and 4-inch brazing support pipes between bays 22 and 29, streamlining the rig’s setup for improved functionality.

Each task was completed with a strong focus on safety and compliance with our client’s high standards, ensuring the rig’s long-term operational reliability. 

  1. Crane Pedestal Maintenance

The crane pedestal is integral to supporting the rig's heavy lifting operations. Our team undertook comprehensive maintenance activities, which included:

  • Inspection and Cleaning: Utilized advanced power tooling techniques to conduct a detailed inspection and cleaning of the pedestal.

  • Structural Reinforcement: Strengthened the pedestal’s structural integrity to enhance its load-bearing capacity and stability.

  • Protective Coating Application: Applied a high-quality protective coating to shield the pedestal from corrosion, significantly extending its service life.

These efforts ensured the crane pedestal remained robust and capable of supporting safe and reliable lifting operations.

  1. Cantilever Maintenance

The cantilever plays a crucial role in supporting the rig’s operations. To maintain its efficiency, we performed the following tasks:

  • Hydro Blasting: Conducted hydro blasting to remove old paint and debris, preparing a clean surface for further maintenance.

  • Protective Coating: Applied a fresh layer of high-performance paint to protect the cantilever from wear and corrosion, enhancing its ability to withstand the rig’s demanding operational conditions.

These activities ensured the cantilever would continue to function optimally, even in the harsh offshore environment.

Challenges and Solutions

The Jackup Rig Maintenance project presented several challenges that required innovative solutions to ensure safety, efficiency, and adherence to quality standards.

  1. Hot Work Challenges

Hot work, including welding and cutting, is essential for maintenance but also poses significant risks, particularly in offshore settings. To mitigate these risks, we implemented the following safety measures:

  • Work Area Isolation: Hot work zones were carefully isolated to prevent any potential fire hazards.

  • Fire Watchers: Deployed fire watchers to continuously monitor work areas, ensuring fire risks were effectively managed.

  1. Height Hot Work

Several tasks required working at heights of up to 120 meters, adding complexity to the project. To safely carry out these high-altitude operations, we employed:

  • Rope Access Techniques: Skilled personnel with rope access training conducted welding and cutting tasks at height, ensuring safety and precision.

  • Rigging and Safety Support: Additional safety personnel oversaw operations, ensuring all activities at height were conducted in full compliance with safety protocols.

  1. Heavy Item Removal

The removal of heavy components, such as cut ladders and pipelines, posed logistical challenges. We overcame these by employing:

  • Advanced Lifting Techniques: Coordinated rigging and specialized lifting equipment were used to safely lower heavy components from significant heights.

  • Safety Protocols: All personnel were equipped with the necessary safety gear, and the entire operation was closely monitored to minimize risks.

Project Completion and Client Satisfaction

Despite the challenges, the Jackup Rig Maintenance project was completed successfully within the designated one-month timeframe. Our team's dedication to clear communication, strict safety protocols, and high-quality workmanship ensured that the project was executed efficiently, with no compromise to safety or operational integrity.

Upon completion, the client expressed their satisfaction with the work performed, commending our professionalism, ability to meet deadlines, and the overall quality of the maintenance. This positive feedback highlights our ongoing commitment to excellence in offshore maintenance.
