The measurement location is in 1,100mt water depth and requires measurements not only throughout the entire water column, but also within 20mt of the sea surface and within 10mt of the seabed.
MSI therefore designed a single 900mt mooring comprising a combination of TRDI 75kHz Longranger ADCP, several Nortek Aquadopp single point current meters and an RBR water level recorder.
The project was mobilized in Aberdeen in January, with the mooring being deployed during a small weather window identified through weather forecasts received from Aerospace and Marine International, one of MSI’s collaborative partners.
The mooring was deployed from the vessel MV Sea Tiger and went smoothly, with all operations being conducted to MSI’s QHSE standards. The first servicing of the mooring is scheduled for May 2010.
Speaking on behalf of MSI, Sidney Bilski said, “We are very pleased to be awarded this contract as this is our first with Chevron North Sea and, although we already work in the North Sea, this is the first time we have mobilised out of Aberdeen.
“We have successfully conducted projects in 27 countries since our inception and this yet again proves that we remain competitive regardless of where the work is located.”
