ACE Winches Completes Equipment Package for Quad204 Project

ACE Winches has completed a scope of work for Technip as part of a subsea infrastructure project in the Loyal field, west of the Shetland Islands.

Quad204 is the redevelopment of the Schiehallion and Loyal fields, located 175 km west of Shetland and 15 km north of the Foinaven field.

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.

The solution from ACE Winches includes a hydraulic drum winch, overboard system and spooling gear, designed and manufactured at the company’s facilities in Aberdeenshire.

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.

All the equipment was fully tested at ACE Winches’ test bed facility and will shortly be mobilised to the client, the company said.

Richard Wilson, chief operations officer, ACE Winches, said: “The limited deck space presented us with a challenge, but we overcame it with an innovative design which delivers a high quality solution that obtains maximum use and efficiency from the area available.”
