Seawork survey vessel sails home to Norway

Robert Olsen, founder and general manager of ROVas, tells MJ that he is very happy with the performance of the vessel.

ROV 1101 has gone straight to work and completed several inspection and survey jobs. The boat is equipped with a Seabotix vLBV 950 with 1,000m depth capacity, with USBL positioning and Olex software for ROV Tracking and seabed mapping. The vessel has been further fitted with several brackets for easy fitting of third party equipment, making it easy to adapt the system configuration specifically for each project.

The first survey job ROV 1101 performed was seabed mapping of a new fishfarm location at Sognefjorden on the West coast of Norway. A Kongsberg EM3002 was used, producing good data for use in planning the anchorage system. The ROV 1101 has proven itself to be a stable and also a very quiet platform which keeps interference with acoustic equipment to a minimum whilst providing a comfortable work environment for the staff.

ROV 1101 subsequently returned to the location in Sognefjorden, doing ROV inspection of the mooring lines and surveying the anchor positions of the fishfarm as it was installed. This data is being used to be able to make a control of the actual line configuration is within the limits of what the tension analysis is based on. All video and data is being transmitted live to the office and workboats performing the work on the mooring lines, and to the office to the end customer, enabling instant decisions on what actions to take as challenges arising during the survey occur. This allows for the entire operation to proceed as seamlessly as possible. It also optimizes cost efficiency through the project , as there is no waiting for the survey data and inspection reports to arrive before a decisions can be made.

ROVas is looking forward to getting the second survey vessel from BWSeacat in November, allowing the company to take on more work with its own vessels.
