Fugro has completed a 33-month long metocean data acquisition for Hess Corp. offshore western Ghana.
The company said on Tuesday that the data acquisition was done in the Deepwater Tano/ Cape Three Points block in a water depth of approx. 2,400 meters. The data is ready for use by Hess as support for its Ghana operations.
A Fugro-manufactured Wavescan buoy was deployed to measure waves, currents and meteorological and seawater parameters, with real-time data displayed on a project-specific webpage.
Long mooring was deployed to measure current profiles over the entire water depth, as well as seawater temperature and salinity.
The company said that it also deployed a short mooring to acquire near seabed currents. Data from both current moorings were stored on board the instruments’ internal memories and recovered during each of the service visits which were at three-month intervals.
Fugro said it utilized vessels from its fleet, including the ‘Fugro Frontier’, to accomplish the nine site visits required, as well as vessels from the spot market.
With the aim of pro-active cost reductions, vessel and personnel mobilizations were minimized by combining site visits with other Fugro operations in the region.
After each service visit, the metocean measurements were processed, analyzed and reported to provide Hess with quality controlled data detailing the metocean conditions in the area.
Jonathan Ainley, Commercial Manager at Fugro GEOS, said: “We demobilized the equipment in June, and we are now processing the data from the final phase. The final report will include data from each of the three stations over the complete duration of the project and will form part of the wider FEED study being carried out by Hess.”
Fugro added that the information will be utilized for engineering activities including riser and facilities design, fatigue calculations and operability calculations, as well as assisting decisions for physical construction at the field.
