ROLLUP JACKET – MABOQUEIRO PROJECT
A Jacket-type platform is an offshore structure built with tubular steel components and anchored to the seabed using piles.
A Jacket-type platform is an offshore structure built with tubular steel components, designed to be anchored to the seabed using piles.
These platforms are primarily used for hydrocarbon exploration and production and are ideal for operating at depths of up to 300 meters.
The platform’s supporting legs are initially constructed onshore and then lifted and rotated 90 degrees during a process known as "Roll up."
The assembly operation of Jacket-type platforms involves several main phases:
- Initial Design: Engineers develop the Jacket structure design, taking into account technical specifications, environmental conditions, and safety requirements.
- Component Production: The tubular steel components and other structural elements are manufactured according to the design specifications. Each individual component undergoes rigorous quality checks.
- Onshore Assembly: Some sections of the Jacket are preassembled onshore to optimize timing. Equipment and structures necessary for lifting and transporting the platform are then prepared.
- Loading onto Transport Vessels: The preassembled structure is loaded onto specially designed ships or barges for offshore transport.
- Offshore Installation and Assembly: Once at the destination site, the Jacket is positioned vertically on the water and securely fixed to the seabed.
Maboqueiro Project Specifications: Deck 1,400 tons, Jacket 2,000 tons, Piles 2,000 tons.
