The systems are designed to perform offshore lifts, and with that, the first few meters are critical. The waves move the vessel up and down, a movement that was independent of the lifting configuration on the platform. The required speed is precisely the reason why Conbit uses very fast lift winches.
For smaller modules, Conbit deploys one such winch. For heavier modules, Conbit can upgrade with an extra one. These winches are operated by diesel-hydraulic power packs, making the lifting configuration independent from the offshore platform utilities.
The independent nature of the modular lifting systems allows deployment at many locations on the offshore platform, supply vessel, drill rig, and other assets. The system installation does not require any support from the deck crane or other heavy equipment. It can be assembled manually using small secondary installation aids. Most components are made of aluminum.
The lifting configuration footprint is flexible. The loads during the lifting operation can be introduced into the strong points of the platform by altering the base frame. Conbit engineers have standardized the footprint arrangement for quick mobilization. For components such as flare tips, Conbit deploys other specialized equipment.
The modular lifting system can be configured for different applications:
- Slewing Application
- Fixed with back cable for extra capacity.
- Fixed base frame (base frame on wheels or skid rails)
All systems are lightweight and can be packed in 10” or 20” offshore containers. Lift winches operate the systems.
