In the offshore oil and gas industry, jackets and topsides are integral parts of an offshore platform. Here’s a general overview of the jacket and topside installation process:
Design & Fabrication
Both the jacket and topside are carefully designed according to the specific needs and environmental factors such as wave height, wind velocity, current velocity, earthquake, etc. After the design phase, they are fabricated onshore in a shipyard or fabrication facility.
Transportation & Installation
After fabrication, they are loaded onto barges and transported to the offshore location where the jacket is installed.
Pile Driving
After the jacket is placed in the correct location, piles are driven through the legs of the jacket into the seabed to provide the necessary stability to the jacket structure.
Topside Installation Once the jacket is installed and secured, the topside is installed. This process can be done in several ways, including piece-small, lift-on, float-over, or jack-up and lift methods.
Commissioning Lastly, all the systems on the topside are tested to ensure they are working correctly.
