Fugro supports Technip's largest North Sea project

Wavescan buoy is enabling Technip to plan its operations more effectively
for its largest UK North Sea contract to date. Located in the west of
Shetland area, BP's Quad 204 project involves replacing the existing
Schiehallion production facility with a new, purpose-built FPSO and
installing extensive new subsea infrastructure.
Fugro Commercial
Manager Jonathan Ainley said, "West of Shetland is known as a harsh
offshore environment with big waves and strong currents ... conditions that
are far from ideal in a construction setting. BP specifically required
reliable real-time wave height, wind, and current data to manage its
installation criteria thresholds. Access to these metocean data is also
critical for vessel management and for safe and efficient operational
planning".
The SEAWATCH Wavescan buoy, manufactured by Fugro in
Norway, is 2.8 m (9.2 ft) in diameter, with a counterweighted keel to
prevent capsizing. It is large enough to cope with the harsh North Sea
conditions. A 3.5-m (11.5-ft) mast supports the buoy's meteorological
sensors and antennae, while a range of subsea sensors monitor
oceanographic conditions.
During its nine-month deployment, sensors
will collect oceanographic and meteorological data including air pressure,
air temperature, current velocity/direction, and water temperature.
Current profilers will be used in two locations (one just below the buoy
and another further down the mooring) to build a current profile for the
full water column depth. Wave data parameters to be measured include
heave, surge, sway, direction, height, and wave period.
The buoy
transmits the data by satellite to Fugro, where it is presented in real
time on a Website that uses a variety of user-friendly pages and options,
including a graphic format (to display current velocity/direction
information for the full water column depth) and tabular data.
