Ingenuity and experience: a perfect combination
DUC Marine Group is certified by Bureau Veritas and Lloyd’s Register to conduct In-Water Surveys (IWS). IWS can be performed in lieu of periodic docking surveys on ships and Mobile Offshore Units.
The In-Water Survey is intended to provide, as far as practicable, the information normally obtained from a docking survey.
Surveys are monitored and recorded by experienced divers in communication with the Class-Surveyor. A full written report and copy of video/still photos are submitted after the survey.
