ACE Winches – the Scottish-based deck-machinery manufacturer for offshore energy supply boats – has delivered one of the world’s largest chain winch packages for Heerema Marine Contractors for its new Aegir vessel. 

Supporting the Ichthys LNG Project off north-west Australia, ACE Winches engineered, designed, manufactured and commissioned a 200 tonne twin Chainlifter hydraulic package for Heerema.

The chain winch package will be used to pull the heaviest chains ever installed by Heerema, with a diameter of 178mm.

ACE Winches also produced two 50 tonne twin Chainlifter hydraulic winches along with a 576kW containerised electric hydraulic power unit.

All equipment was engineered and designed by ACE Winches and manufactured at the company’s global headquarters at Turiff in Aberdeenshire before being transported across the world for commissioning in Australia.

Due to the complexity of the project, Heerema, in partnership with ACE Winches, evaluated different systems and developed safe and practical solutions.

The determined solution was to lay the chains on the barge then reel them off with the help of the chainlifter winch packages.

Jan van Akkeren, Heerema’s senior vice-president of operations and asset management, visited ACE Winches in Scotland on completion of the chainlifter packages.

He said: “We chose ACE Winches because the equipment has to be technically perfect and also cost effective. Heerema has built up a relationship with ACE Winches over the years and its technical and financial evaluation came out the best.”
