The modular upgrade replaces the crane’s original steel wire rope with high-performance synthetic fibre rope, using the same technology as MacGregor’s advanced fibre-rope crane, the FibreTrac 1500. Effectively, a 100-tonne fibre-rope crane has the same lifting capacity as:
- a 150-tonne crane with steel wire rope, lifting at a depth of 2,000m
- a 200-tonne crane with steel wire rope, lifting at a depth of 3,000m
- a 250-tonne crane with steel wire rope, lifting at a depth of 3,500m
The retrofit system is designed in modules for rapid installation. It includes a deep water capstan traction device, delivered in partnership with Parkburn Precision Handling Systems, which replaces the crane’s original main winch and overcomes the problems traditionally associated with handling fibre rope. The system also includes a low tension fibre-rope storage drum.
This short animation shows the benefits of MacGregor’s retro-fit fibre-rope solution employed on a 100-tonne active heave-compensated (AHC) crane.
