Installing offshore jackets, which are steel structures supporting platforms or other facilities in offshore environments, involves a series of complex operations. Here's an overview of the typical procedures involved:
*1. Preparatory Phase:*
- *Site Survey and Preparation:* Conducting detailed surveys of the seabed to assess conditions and identify potential hazards. Preparing the installation site by clearing obstacles and ensuring a stable foundation.
- *Jacket Fabrication:* Fabricating the offshore jacket structure onshore or at a fabrication yard. This involves welding together steel components to form the jacket's frame and outfitting it with necessary equipment and fixtures.
2.*Transportation to Site:*
- *Loadout and Transport:* Loading the fabricated jacket onto a transportation vessel, such as a barge or heavy lift vessel. Transporting the jacket to the installation site using tugboats or specialized vessels.
3. *Installation Operations:*
- *Positioning and Pre-Installation Surveys:* Using positioning systems such as GPS and acoustic transponders to accurately position the transportation vessel over the designated installation location. Conducting final surveys to ensure precise alignment.
- *Jacket Lowering:* Gradually lowering the jacket structure into the water using hydraulic jacks or winches mounted on the transportation vessel. This process requires careful control to prevent damage to the jacket or the seabed.
- *Pile Driving:* Driving the jacket's foundation piles into the seabed using hydraulic hammers or vibratory pile drivers. This secures the jacket in place and provides stability against environmental forces such as waves and currents.
- *Grouting and Welding:* Grouting the connection between the jacket's legs and the foundation piles to enhance structural integrity and prevent corrosion. Welding additional components such as boat landings, access ladders, and utility platforms.
*4. Post-Installation Phase:*
- *Platform Installation:* If the jacket serves as a support structure for an offshore platform, additional installation operations, such as topside module installation and integration, will be carried out following the jacket installation.
- *Testing and Commissioning:* Conducting tests and inspections to verify the integrity and functionality of the installed jacket structure. This may include load testing, non-destructive testing, and functional testing of equipment.
- *Handover and Operations:* Handing over the completed installation to the client or operator for commencement of offshore operations. This may involve training personnel and providing documentation on the installed structure.
