New Jetting Tech from James Fisher Subsea Excavation

  • Business & Finance

Subsea excavation specialist James Fisher Subsea Excavation (JFSE), a part of James Fisher and Sons plc, has introduced new centrally-located jetting systems to its mass/controlled flow excavation (M/CFE) equipment spreads.

“The high velocity water jet, designed, developed and patented by JFSE, facilitates the excavation of soils previously considered too dense to excavate using traditional mass/controlled flow techniques,” the company said.

The development of this new technology follows the recent successful launch of the MultiROV, an exclusive ROV system which provides new levels of controllability and productivity, as well as the Twin T8000 which has the highest volume output of any subsea excavator in the world.

Commenting on this latest M/CFE innovation, Graham Murdoch, technical director at JFSE, said: “We are committed to using our world-leading knowledge and expertise to continue to lead innovation in the sector. Our developments are all designed to bring very real, tangible benefits to our clients.”

“Discussions with our clients identified this enhancement would offer significant benefits. We undertook a detailed computational fluid dynamics exercise to fully understand the effects of this setup and the results were impressive. We can now cut soils with shear strengths almost double that which any other M/CFE system can realize.”

The jets are now being fitted to JFSE tools which are stationed at strategic hubs in the UK, UAE, Singapore, Venezuela, USA, Brazil, China and Mexico.
