Seismic Survey begins in Algoa Bay

By

The Motor Vessel Polarcus Nadia begins conducting a 3D Seismic Survey offshore Algoa Bay, Port Elizabeth today, 10 December 2013.

The 3D survey Vessel will be towing a configuration of ten streamer cables each of 6 km length spaced 100 meters apart at an average depth of 10 m astern of the vessel. The streamers are not visible on the surface.

Operational area stretches across the bay from inline with the from Gamtoos River Mouth to Bird Island.

The vessel has restricted manoeuvrability and needs a 5 NM radius clearance around the vessel.

The vessel is currently deploying equipment and operations are due to commence the 10th of December 2013.

The Polarcus Nadia is a 12 streamer 3D/4D seismic vessel that was launched in 2009. Built to the ULSTEIN SX124 design and incorporating the innovative ULSTEIN X-BOW® hull, this vessel combines the latest developments in maritime systems with the most advanced seismic technology commercially available. The vessel is also amongst the most environmentally sound seismic vessels in the market with diesel-electric propulsion, high specification catalytic convertors, double hull, and advanced bilge water cleaning system. This vessel complies with the stringent DNV CLEAN DESIGN notation.
