J              06°57’.991 N     055°02’.991 W

The survey vessel will tow seismic cables with a length of eleven kilometer (11 km) and a width of two kilometer (2 km), which are ten to twenty meters (10-20m) below the water surface. At the end of the cables there will be tail buoys with white flashing light attached. The vessel will sail with a speed of 3-5 knots.

Vessels must maintain a safe distance of at least nine nautical miles (9 NM) of Geo Caribbean. The Offshore Support Vessels (OSV) that will assist during the operations are Victory G, Astra G and Linde G.

Please note:
• Communication is through VHF channels 16 and 72.
• There is a SAFETY ZONE of nine nautical miles (9 NM) around Geo Caribbean.
• Geo Caribbean will sail at different courses, has restricted maneuverability and will display the relevant characters.

All ships should take notice of the above mentioned.
