U.K.-based James Fisher Subsea Excavation (JFSE) utilized an approach akin to a Swiss Army Knife in developing the MultiROV system, an innovation that brings 30 equipment spreads to bear on issues in the deepwater market.

“The MultiROV will bring real benefits to our clients with a range of challenging requirements,” said Graham Murdoch, technical director at Fisher. “Automated heading and positioning controls greatly increase both productivity and the operational working limits.”

The MultiROV system, which can be deployed in water depths in excess of 3,000 m (9,843 ft), does not require stabilizing tuggers or clump weights, which reduces the services it needs from a vessel.

Fisher said that its new system brings new levels of controllability and productivity for excavation requirements to the offshore oil and gas sector as well as renewable energy sectors. The system allows for tailoring of solutions for subsea excavation clients by deploying proven and established technologies alongside pioneering innovations.

“We are extremely pleased to be involved in this development project with JFSE,” said Gary McConnell, business development manager at Aleron Subsea.

JFSE’s excavation equipment married with Aleron’s technically advanced ROV products have produced a bespoke system for challenging applications within the subsea excavation market, he said.
The MultiROV system can run a multitude of survey sensors that provide flexible options for the real-time data captured during operation. It can also deploy and use manye other subsea tools including shears, cutters and grabs.
