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
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.
Self-Installing Topsides
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.
ICON Mini-MOPU
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.
