The advent of digital video brings with it a new era for the offshore oil and gas industry. Digital methods of data acquisition have now permeated most offshore survey techniques, with satellite transmissions, acoustic positioning signals and most forms of sonar data being generated and recorded in digital form. A workgroup established by the Offshore Survey and Remote Systems & ROV divisions of the International Marine Contractors Association (IMCA) has developed a publication "Digital Video Offshore: A Review of Current and Future Technologies" for the benefit both of offshore contractors and their clients.

The aim of this publication is to encourage the widespread use of digital video and to provide information on how the data is captured, synchronised with traditional survey information and compiled into digital reports for delivery to the end client.

The publication has been written to provide an understanding of digital video technology, the potential benefits available over existing analogue technology, practical applications and issues relating to the development of standards within the survey industry. Within the review there is discussion of the many factors affecting the quality of recorded digital video data, including the quality of the hardware from the camera through to the recorder; the method of data transmission, and the environment in which the camera is used. In addition, the document addresses the alternative approaches or philosophies taken by different clients to the acquisition and use of digital video, including selection of media storage options and integration with GIS systems.
