Accelerated delivery of an A-Frame and Fast Winch System complete with Active Heave Compensation
Challenge
A valued client contacted Ashtead Technology with an emergency requirement for a compact mechanical handling package for critical offshore subsea deployment and recovery operations. The application included the safe handling of mattresses and ROV baskets in water depths up to 1,350 metres.
Solution
To meet the client’s operational requirements and project schedule, the scope of work included the design and build of a new retractable A-frame and a 60Te hydraulic drum winch complete with active heave compensation capability.
The project was delivered through a fully integrated end-to-end process, with every stage managed in-house – from initial engineering and design through fabrication, machining, assembly and testing.
The process from concept to completion included:
- Defining the operational scope and system requirements
- Mechanical engineering and structural design
- Hydraulic engineering, including schematics and calculations
- Electrical engineering and control system design
- Fabrication and welding of the new A-frame structure
- Precision machining of components
- Surface preparation and painting
- Mechanical assembly, hydraulic and electrical build
- Full documentation package, including drawings, manuals and certification
- Full factory acceptance testing (FAT) and load testing prior to delivery
Leveraging our in-house capabilities, Ashtead Technology delivered the complete package in just 11 weeks.
Results and impact
The A-frame and fast winch system complete with active heave compensation was successfully delivered ahead of the scheduled time, demonstrating the advantages of a fully integrated in-house delivery model.
- Rapid turnaround from concept to delivery
- Successful integration of a 60Te winch with a new build A-frame
- The addition of active heave compensation for precise control, increasing positioning accuracy for subsea tasks and reducing risk of damage to sensitive subsea equipment
- Fully tested and certified deployment system ready for offshore operations
- Reduced project risk and improved quality control through complete in-house engineering, fabrication, machining, assembly and testing
