ROV Sonar and Visual Pictures From the Field Trial Deep Spill, June 2006

摘要

The Deep Spill experiment was carried out in the Norwegian Sea (at 65o N, 4o 50 E) during 26 29 June 2000. The purpose of the field trial was to survey releases of oil and gas at the sea floor in order to improve on the contingency against deep water spills. In addition, numerical models for deep water oil and gas spills were compared to the results from the measurements. As a part of the experiment, recordings of the underwater plume generated from the releases of the oil and the gas on the sea floor were carried out by means of a Remote Operating Vessel (ROV). These recordings included measurements with a sidescan sonar as well as visual pictures. In addition, counts of oil droplet and gas bubble size distributions were carried out based on the visual pictures taken by the ROV. This data report contains a description of the results that was obtained by means of the ROV recordings. The ROV was hired from the company Oceaneering (located in Stavanger, Norway) and was of a type denoted Scorpion 10. The report starts with a general description of the equipment used, and an overview of the data taken (Chapters 1 - 5). An inspection of the release arrangement on the sea floor was also carried out (Chapter 6 7). Then a general description of the results obtained from the measurements is given (Chapters 8 11). Finally, an analysis of the oil droplet and gas bubble size distributions is carried out (Chapters 12 14).
