Self-Installing Mini-MOPUs, Wellhead Platforms & Topsides
ICON has perfected the science of installing offshore facilities without the use of a drilling rig or a large crane barge.
ICON can also design cost effective flexible alternatives to standard topsides where different operations are required for only part of the platform’s life.
Pre-Installation: the legs have not been lowered yet
The legs have now been lowered to the seafloor, and ready to be jacked up for the barge's departure.
Self-installing platforms allow for installation without the use of a drilling rig or large crane barge.
This method may be economically advantageous where a drilling rig is not already on hand, as derrick barges are expensive to mobilise and operate.
ICON has the technical knowhow and experience to equip self-installing Platforms with a range of adaptable foundations making them ideally suited for small, prolific fields.
This approach involves winching modules to the underside of superstructures before they are secured in place. This concept allows for a cost effective flexible alternative to standard topsides where different operations are required for only a part of the platform’s life.
The module interface can be standardised allowing for flexible reuse of modules on prolific fields. ICON has pioneered the design and installation of self-installing topsides.
The ICON Mini-MOPU is a relocatable self-installing offshore production platform. It is designed for low cost delivery and installation. It suits relocation due to its jackup-like design.
Unlike traditional buoyant MOPU’s the platform does not have in-built buoyancy or a permanent in-built jacking system. The installation method eliminates this need. The result is a significantly lighter and lower cost structure which does not need to be designed to float or have expensive permanent jacking systems.
The benefit is a lower total cost solution, and a significantly lower cost per unit for multi-platform field developments. The installation hardware is rented or used multiple times, thereby reducing the unit cost and CAPEX.
ICON’s Mini-MOPU solution has many unique features including:
- The primary structure can be fabricated while removable modules are being designed and built.
- The well bay design allows well handover to a more permanent fixed production platform and redeployment of the Mini-MOPU if desired.
- No permanent buoyancy required, eliminating expensive permanent hull and associated marine hardware.
- Removable jacking system, able to be redeployed on multiple Mini-MOPU’s.
- Three different foundation solutions available: suction piles, driven piles & drilled piles.
