Helix Energy Solutions Group’s newbuild charter ROV support vessel, Grand Canyon, recently completed sea trials and is ready to begin operations in the North Sea. During the sea trials the vessel’s propulsion system, dynamic positioning system and all her cranes were tested.
The vessel recently completed its outfitting in Norway after the initial hull construction was completed in Turkey. Grand Canyon is capable of launching five ROVs at once and will be operated by Helix ESG’s robotics subsidiary, Canyon Offshore.
The vessel will be the new home for another recently completed asset, the T1200 trenching unit. Used primarily to bury large diameter power cables leading from offshore windfarms, the T1200 is also capable of working on oil and gas projects to bury production pipelines.
The Grand Canyon was designed to provide a high capacity, stable working platform for lay, burial and general offshore construction work while still retaining a shallow draft, which is crucial when operating close to the coastline, and common in the renewable energy sector.Grand Canyon’s DP3 capability allows her to operate in any sector, providing offshore support in a wide variety of roles.
The vessel’s deck structure is specifically designed to accept trenching and flexible pipe or cable lay systems for safe and efficient mobilizations. A key focus throughout the design and build of Grand Canyon was to optimize the vessel and equipment design to facilitate efficient mobilizations.

Need to cut a 30 foot deep trench in the bottom of the ocean floor to run flowlines out to a new production rig?
No problem. Helix Energy Solutions’ new T1200 subsea trenching behemoth is just what you’re looking for.
Looking like a mix between a space ship and an Abrams battle tank, the T1200 is a massive piece of equipment weighing in at over 33 tons (30,000kg) and towering to a height of 12.6ft (3.8m).
While not yet in service, construction of the T1200 trenching and burial unit is one step closer to entering service following testing and installation of its two enormous caterpillar tracks.
The vehicle also got wet for the first time in the manufacturer’s test tank in central England. Still undergoing final fitting, the T1200 is expected to be delivered to Helix ESG this summer and will begin work on board another new asset to Helix ESG’s ROV Support Vessel fleet, the Grand Canyon.
The 1,125hp ROV will use high-powered water jets to cut up to 30 feet into the seafloor and lay power cables, or other tubular products like oil and gas pipelines.
The Grand Canyon is a new build offshore construction vessel that will host a new T1200 jet trencher, two 200HP XLX ROV systems onboard along with two more ROV systems. The Grand Canyon is 125m x 25m and has a 250t crane, monopool, dynamic positioning systems and helideck. Accommodations are for up to 108 personnel and will be deployed for work in Europe’s growing offshore wind farm projects where her ROVs will conduct power cable trenching and burial operations.

Tersan Shipyard launched Multipurpose Offshore Construction Vessel, Grand Canyon with the honorable presences of Norway Prime Minister Mr. Jens Stoltenberg and Turkey Minister of Transportation, Maritime Affairs and Communication Mr. Binali Yıldırım.
Grand Canyon is a cooperation of Tersan Shipyard with Bergen Fosen in order to build a very high standard Offshore Construction Vessel for the Owner, Volstad Maritime. Grand Canyon is a 125m long, 25 m width, electric propulsion offshore vessel with Helicopter deck, DP III notation, 6 pcs of Side Maneuvering Thrusters and accommodation for 108 persons.
During the ceremony, Mr. Stoltenberg pointed out that it was no coincidence that the launch was on his itinerary during his visit to Turkey.
“Norway and Turkey have a long tradition of business cooperation in the maritime sector. Tersan shipyard alone now has a total of eight ships on order for Norwegian interests, worth a total of almost NOK 2 billion,” Mr Stoltenberg said.
Mr Stoltenberg was also able to see the M/S Høydal, a Norwegian ship which is being built at the yard on behalf of the company NSK Shipping, based in North Norway. The M/S Høydal is a specially designed cargo ship that will be assigned to the fish feed manufacturer BioMar in Norway. This will be the world’s first LNG-powered coaster, and the vessel should be ready to load her first cargo in Norway in May 2012. The M/S Høydal will have a cargo capacity of 2200 tonnes of fish feed, making her the world’s largest operational fish feed cargo vessel. Natural gas (LNG) propulsion will make the vessel environmentally friendly and reduce emissions of NOx (nitrogen oxides) by over 90 %.
Mr. Binali pointed out the increased capacities of Turkish Shipyards, highlighted that he had attended to another launching ceremony in Tersan Shipyard just 4 months ago, this represents Tersan Shipyards and Turkey’s achieved high level of Ship production as well as quality; “When I was the General Manager of IDO, Turkey used to import ships from Norway just 10 years ago now we are exporting vessel to Norway” said Mr. Yildirim.
