Controlled Flow Excavation from JFO

JFO have had the busiest ever start to a year for controlled flow excavation (CFE) projects.  With 14 global projects operational throughout Q1 2021, JFO are continuing to provide its customers with the most suitable technical and commercial solution for their project requirements.

 

Gulf of Mexico


Mobilising from our GOM facility, the JFO TwinProp controlled flow excavation (CFE) tool will support our customer with seabed levelling for a new offshore construction project in region.

Following completion of this project, the same tool will stay in region and begin work on a pipeline trenching scope of work.

 

Oman

Operating in shallow waters of between 2-11m, the JFO Twin R4000 excavation tool is delivering pre-trenching, trench maintenance and backfilling requirements for the installation of pipelines for fibre optic cable. The Twin R4000 is the ideal solution for delivering a non-contact method of excavation while operating effectively in shallow waters.

 

Indonesia

A total of 139km of 23mm fibre optic submarine cable requires free span rectifcation in the Strait of Malacca, the longest trenching route to ever be completed by JFO.

 

New Zealand

Operating multiple CFE tools, an expert team of JFO offshore technicians are supporting our customer with a Civils construction project in New Zealand. Scope of work includes seabed preparation and trenching of 20m x 3m @ 4m below seabed level.

 

UK/Europe

Work continues for our valued customer on the Hornsea 2 offshore wind farm, where we are currently supporting two ongoing cable proejcts - cable de-burial followed by re-trenching. We are operating our SP600 CFE tool with its own LARS, allowing for the vessel crane to be free for simultaneous operations.

 

Qatar

Post lay trenching and backfilling of composite cable and fibre optic cable at a water depth of between 50 and 70m to begin mid-February.
