MacArtney AHC Winches for Canyon Offshore ROV Vessels
Canyon Offshore Inc., the marine contracting unit of Helix Energy Solutions, has opted for a MERMAC electric winch solution to empower the safe and efficient handling of ROV systems on board the latest two additions to the Grand Canyon family of advanced offshore support vessels.
MacArtney has supplied a total of four winch systems, all featuring active heave compensation (AHC) allowing Canyon to launch, operate and recover their ROVs under rough sea conditions.
With a global track record spanning two decades and a fleet of several purpose-built offshore support and construction vessels carrying ROV, geotechnical and trenching systems, Canyon Offshore is a supplier of subsea intervention, construction and engineering services.
The Grand Canyon vessel range comprises three identical ships (Grand Canyon I, II and III) delivered between 2012 and 2016, each delivered with the latest technology and powerful systems to maximize performance, flexibility and (cost) efficiency. The vessels are able to perform a broad range of subsea operations with high maneuverability and DP3-class station keeping for enabling work in severe weather conditions. All Grand Canyon vessels will feature a 250 t heave compensated crane, as well as dual ROV systems.
Installed inside the port and starboard hangars of the Grand Canyon II and III, each of the MacArtney MERMAC R40 winches will be utilized to deploy two ea. 3,000 meter rated work class ROV systems which form the backbone of the subsea intervention toolkit of each vessel. Enabled by an integrated AHC system, the winches are able to actively filter out the effects of vessel motion (heave, pitch and roll) hereby allowing Canyon to expand its window of ROV operation and substantially reduce weather related downtime.
