Abstract
The offshore oil and gas industry in the North Sea has set new standards and led to increased demands for accurate and cost effective subsea mapping and inspection techniques. The present paper reviews some of the recent advances within this field and focuses on different three dimensional (3D) mapping and imaging techniques. A new class of high resolution wide-swath bathymetric systems is described and compared. These systems requires positioning input of the highest accuracy and consistency and the role of the Global Position System (GPS) to meet these demands is discussed.
The paper puts special emphasis on the potential use of laser scanning and laser radar techniques for high resolution 3D-imaging and mapping. The basic criterias for use of optics subsea are discussed and exemplified through the description of SPOTRANGE and SPOTSCAN instruments as well as a new concept for a laser radar now being developed at Seatex.
