Operations are scheduled to begin tomorrow (Tuesday 11 July) with provision to start earlier on Friday 7 or Saturday 8 July, and will last three months, weather dependant.
The vessels involved will be the seismic vessel Polar Marquis (Callsign LAOI5), which is towing a spread of 12 x 8100m cables with a width of 1,540m just below the surface.
The support vessel is the Moonrise GSL (Callsign HPEW) and the guard vessel is the Ary (Callsign YJQJ5).
There will be radio transmissions to vessels in the vicinity, with warnings broadcast on VHF Channel 16. Tail buoys will be used on the end of each streamer; they are yellow in colour and are equipped with strobing lights and radar reflectors.
At the end of each survey line, the vessel requires an area to turn around; this is some 15km in addition to the area confined within the coordinates given.
