Deep water geophysical and survey vessels for COSL

COSL720 is a 12-streamer dual-detector giant geophysical vessel powered by both diesel and electricity capable of navigating in unrestricted waters. It will be mainly used for collection of 3D seismic data in deepwater. COSL708 is an electricity-powered deep-water exploration vessel capable of navigating in unrestricted waters. It will be mainly used in geological surveying for ocean-bound engineering projects.

These two vessels constitute parts of the integrated supporting facilities in COSL’s deep-water key-technology initiatives.

COSL720 is to be built by Shanghai Shipyard Co., Ltd. and will be rated by China Classification Society upon completion. COSL708 is to be built by CSSC Guangzhou Shipbuilding Company Ltd. and will be rated by both China Classification Society and Det Norske Veritas upon completion.
