ScanFish ROTV Sensor Payload Expanded by 700%

Designed to function as platform for subsea sensors, the EIVA ScanFish remotely operated towed vehicle (ROTV) comes standard with a maximum sensor payload of 50 kg. But a design upgrade was needed when marine geophysical-geotechnical service delivery specialist PanGeo Subsea contacted EIVA to discuss the possibility of using the ScanFish together with its Sub-Bottom Imager (SBI) unit, which weighs 300 kg.   The EIVA R&D team took up the challenge in May 2017. Four months later, a ScanFish XL was introduced at the EIVA Days Denmark 2017. The ROTV itself measures 4.33x2.73x2.77 meters. It

First Ever USV-supported Cable Route Survey

For the first time ever, a seabed cable route survey has been performed with support from an unmanned surface vehicle (USV).   The survey route included various water depths and strong currents, while facing difficult wind and sea conditions in the Bering Sea offshore Alaska. The project was mobilized immediately following a 9,000km nautical charting survey by Terrasond, of which 4,750km (53 percent) was executed by an ASV Global C-Worker 5 autonomous surface vehicle (ASV). The cable route survey required a new payload including a hull mounted multibeam sonar, a sub-bottom profiler, and a towed

Marine Hazards to Subsea Cables and Pipelines

In February 1989 the RoRo vessel Vinca Gorthon ran into heavy weather and sank off the Dutch coast. She landed on an oil pipeline that was severely damaged. Although the probability of sinking on top of a pipeline is very small, the incident showed that it can happen.   Shipping traffic can represent a potential hazard to subsea pipelines in various ways, such as sinking or grounding, lost containers or an anchor hooking onto a pipeline. Over the years MARIN has contributed to the development of a method by which the burial depth of a cable or pipeline is determined on the basis of actual

Changing the Landscape of LNG Production

Successful completion of the Petronas Floating LNG facility (PFLNG) Satu is a milestone for the oil and gas industry and for the Malaysian energy giant.   Designed by consortium leader TechnipFMC and fabricated at the Daewoo Shipbuilding and Marine Engineering yard in South Korea, PFLNG Satu achieved the first-ever production of LNG offshore in December 2016.   The 365-meter by 60-meter facility processes, produces and offloads LNG in situ, directly above natural gas reservoirs. FLNG allows the monetization of remote, marginal and stranded offshore gas fields that cannot be developed

Cable Repair Restores Power Scilly to Islanders

CWind’s specialist cable installation vessel, the C.S. Sovereign, has completed a power cable repair to reconnect the Isles of Scilly to mainland electricity.   The power cable was damaged late February by an anchor, a common occurrence with telecommunications and power cables. The C.S. Sovereign, along with her crew of cable engineers and specialist cable equipment and machinery, was contracted for the repair and rapidly mobilized.   Using remotely operated underwater vehicles (ROV) deployed from the back deck of the C.S. Sovereign, the vessel and technical team onboard surveyed

Prysmian Bolsters Offshore Cable Production

Responding to an increased demand for European offshore wind farms, energy and telecom cable systems manufacturer Prysmian Group has expanded capability at its U.K. production facility in Wrexham to manufacture both 33 kV and 66 kV submarine cable cores used for the inter-array cable connections in offshore wind farms. The new product line will enable the linking and collecting of power produced by offshore wind turbines before onward transmission to the onshore grid.   Llyr Roberts, CEO Prysmian UK comments “Our Wrexham factory has been manufacturing the highest quality cables for

Work Class ROVs

An invaluable resource for the marine industry, remotely operated vehicles (ROVs) perform a multitude of tasks, from pipeline inspection to subsea construction, often equipped with an array of cameras, sonars, sensors, manipulators and other tools to go to work where divers cannot. Power and payload, ruggedness and reliability: these are crucial to the heavy class ROVs examined here in part 2 of MTR’s ROV technology series.   DOER Marine DOER’s H3000 is a midsize work class ROV. Designed for multimission use from a variety of platforms, the H3000 is well suited to underwater tasks
