Excavation specialist James Fisher Subsea Excavation (JFSE) has launched a new mass/controlled flow excavation (M/CFE) MultiROV system for the offshore oil and gas sector. 

The MultiROV system provides new levels of controllability and productivity to perform excavation. 

JFSE said that the system also reduces the services required from a vessel as it needs no stabilising tuggers or clump weights.  

It is equipped with on-board thrusters to allow movement and heading control to increase operational window and productivity. The configuration of the system enables it to be deployed in water depths of more than 3,000m.

JFSE technical director Graham Murdoch said: “This is an exciting advancement in excavation technology. The MultiROV will bring real benefits to our clients with a range of challenging requirements.

The system comes with data hosting ability to run multiple survey sensors that will allow the operator to procure real-time data during operation. 

Further capabilities of the MultiROV allow deployment and other subsea tooling, including shear cutters and grabs.

The MultiROV facility is developed along with ROV specialist Aleron Subsea.

JFSE holds exclusive rights of the system worldwide.

All JFSE tools allow a non-contact form of excavation, thereby eliminating risks usually associated with other excavation methods, especially in complex subsea assets. 

A part of the James Fisher group, JFSE has presence in more than 40 countries.
