Subsea 7 - BP West Nile Delta gas development

Scope of works:

James Fisher Offshore (JFO) successfully completed a work scope consisting of 9 well tie-backs with Subsea 7.

As part of the first phase, Taurus and Libra required the installation of:

- 80km of 24” and 4” rigid flowlines- 24km flexible flowlines
- 1km of 4” flexible jumpers
- (3 off) 24” pipeline end terminations
- (4 off) 4” pipeline end terminations
- (2 off) subsea distribution assembly mudmats
- (3 off) umbilical termination assemblies
- (4 off) 24” spools
- (1 off) 36” spool
- (3 off) manifolds c/w suction piles
- 75km of umbilical and a large quantity of hydraulic/MEG flying leads

Scope of supply:

JFO provision included a 20T hydraulic winch package supplied with hydraulic power unit (HPU) and load monitoring equipment for uses in a Zone 2 hazardous environment, along with highly skilled technicians.

During operations, Subsea 7 suffered difficulties with existing deck tuggers and JFO’s proactive team managed to overcome the issues and get the full equipment package back into working order during pull-in operations.

By way of acknowledgement, JFO’s lead technician received a safety award from Subsea 7. Subsea 7’s hook-up offshore HSE advisor on the Rockwater 2 commented,

“During fault diagnostics of the (Subsea 7) aft back tugger, I observed the Fisher group tech show great work ethic and willingness to work as a team member in the result of repairing the tugger in quick time whilst lifting ops were at a critical stage.”
