ACE delivers subsea infrastructure project

The complete project will see an existing floating production storage and offloading (FPSO) vessel replaced with a larger, purpose-built FPSO to accommodate new field tie-ins. The development of additional wells and the installation of new subsea infrastructures in neighbouring fields are also planned.

Challenged by limited deck space, the company developed a package that houses the hydraulic drum winch, with a safe working load of 150te across all layers, an overboard system and spooling gear into the winch base frame. The winch package includes closed loop hydraulic power units, located nearby.

A custom-made compact winch was designed to accommodate the limited space and meet the required performance characteristics for riser installation, while the overboard system provides access to the tower, with ladders and walkways included.
