Subsea intervention, construction and engineering firm Canyon Offshore has opted for a Mermac electric winch solution to handle ROV systems on board the latest two additions to its Grand Canyon family of 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.
The Grand Canyon vessel range comprises three identical ships (Grand Canyon I, II and III) delivered between 2012 and 2016.
All the Grand Canyon vessels were delivered with the latest technology and powerful systems in order to maximize performance, flexibility and (cost) efficiency. The vessels are able to perform a broad range of subsea operations with high manoeuvrability and DP3-class station keeping for enabling work in severe weather conditions.
All Grand Canyon vessels feature a 250-tonne 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 used to deploy two ea. 3000m-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.
