Rosebank currents assessment under way
Chevron North Sea has contracted Metocean Services International (MSI) to measure currents on the Rosebank discovery west of Shetland.
SANDY BEACH, Australia -- Chevron North Sea has contracted Metocean Services International (MSI) to measure currents on the Rosebank discovery west of Shetland.
The results will support planning, engineering design, construction, and installation of potential production facilities on the field.
MSI says the location, in 1,100 m (3,609 ft) water depth, requires measurements throughout the entire water column and also within 20 m (65.6 ft) of the sea surface and within 10 m (32.8 ft) of the seabed. It devised a single 900-m (2,953-ft) mooring comprising a combination of a TRDI 75 kHz Longranger ADCP, numerous Nortek single-point current meters, and an RBR water level recorder.
The 12-month minimum project was mobilized from Aberdeen in January, with the mooring installed during a tight weather window identified by weather forecasts issued by MSI’s collaborative partner, Aerospace and Marine International.
The mooring was deployed from the MV Sea Tiger. To date, operations have run smoothly, MSI reports, with first servicing of the mooring scheduled for May.
