ExxonMobil Guyana Metocean Moorings Project

RPS designed and installed five metocean moorings to collect accurate in-situ measurements with ExxonMobil’s Caribbean deep water offshore prospect, Liza-1 and Ranger, to the north of Guyana. The metocean mooring equipment was specifically selected to accurately measure the following parameters under rigorous conditions: Offshore Oceanographic Characterizations:
  • Waves (Hs, direction, period)
  • Current Profiles (intensity, direction)
  • Tides (constituent amplitude, phase)
  • Temperature, Salinity, & Density Profiles
  • Corrosion testing
  • Marine growth
Offshore Meteorological Conditions:
  • Wind (intensity, direction)
  • Air temperature
  • Precipitation
  • Relative humidity
  • Sunlight
  • Atmospheric pressure

The moorings are currently deployed in water depths of approximately 1760m. The measurement program at Liza-1 is expected to run through March 2018 with service visits occurring at three to sixth month intervals.

All recovered data undergoes data conversion and data processing using RPS software. After each data collection period, RPS provides semi-annual metocean data review and analysis reports.
