Subsea Umbilicals, Risers and Flowlines (SURF)

The SURF infrastructure on the Anyala/Madu project comprises of subsea umbilicals, flexible risers and flow lines, rigid pipelines, and a subsea mid-water arch.
The Anyala West Conductor Supported Platform (CSP) is connected to the FPSO, approximately 105 metres away, by 4 flexible risers for crude production and gas lift purposes.
The Madu CSP ties back to the FPSO, approximately 23km away, via a combination of 3 flexible flowlines and 3 rigid pipelines for crude production and gas injection purposes.
The umbilicals serve as a carrier for power and fibre optic cables, as well as hydraulic hoses. This enables transmittal of power supply and control signals from the FPSO to the unmanned CSPs.
The mid-water arch serves as a support structure to secure a combination of 14 flexible risers and umbilicals from the FPSO to the Conductor Supported Platforms. The 170-tonne mid-water arch is 20m high and 19m wide with 4 piles for stability.
The loadout of the Anyala West and Madu flexibles, umbilicals and mid-water arch commenced in Europe on March 15th, 2020. The transportation vessel (SAL Lone) arrived at Anyala field on June 10th, 2020 and commenced the offshore installation campaign. The offshore installation was executed in two phases with the successful hook-up, tie-in, and pre-commissioning of the flexibles and umbilicals achieved by September 14th, 2020 in readiness for production.
