Alpa Winch is a redundant high-risk application for lifting over Hydro Carbon Pressurized systems and is the only system of its kind with an approved DVR from DnV GL.

The system is designed for safe and easy installation and mobilization with minimum service and maintenance requirements. The system can be adapted to various interfaces due to the system's unique design philosophy which enables multiple interfaces without changing the main structure.

The load path when lifting consists of dual load carrying parts. This ensures that a single failure does not lead to a dropped load. The unique winch design ensures evenly distributed loads in the system in all situations. The control system gives real-time feedback on the status of the system, and has interlocks winch ensures the safety and functionality of the system.

The hydraulic system can be connected to an existing ring line system, or be delivered with a redundant HPU.

The system can be interfaced to the following
(but not limited to):

  • Traversal crane with various design
  • DDM
  • Fixed structures


  • Redundant HPU
  • Multiple interface solution
  • Redundant slewing hook
