HYDROGRAPHIC SURVEY
Filling in missing information for offshore engineers
Survey companies are investing heavily in new equipment in order to improve their accuracy and to perform better in inhospitable environments. Sean Ottewell reports.

ugro OSAE has been awarded a €2.3m hydrographic survey contract by the Norwegian Hydrographic
Service (NHS). Te survey is part of the MAREANO project and will encompass an area over 12 000 km² in the Barents Sea. Te area is located 200km offshore in the northern-most part of Norway, near the Russian border, in water depth down to 300metres. As the North Atlantic current keeps the waters in this area open and navigable most of the year, the survey will be carried out in early 2012. Data will be acquired by the survey
vessel Victor Hensen using the new, high- resolution Kongsberg EM2040 multibeam echo sounder. Processing will take place on board the vessel and at Fugro OSAE’s processing centre in Bremen, Germany. MAREANO is Norway’s programme
to fill knowledge gaps related to seabed conditions and biodiversity along the northern Norwegian coast. Te goal is to contribute to a better knowledge base

for resource management, in particular for fishing and oil and gas exploitation. Te acquisition of detailed and accurate bathymetry is an important first step in the collection of seafloor data. Fugro OSAE has previously conducted
surveys as a part of the MAREANO project area in 2006, 2007, 2008 and 2010 as well as collecting high resolution bathymetry data for Norwegian electronic nautical charting (ENC). Meanwhile Fugro Survey (Perth) is
shortly due to commence a deepwater AUV survey as part of the Woodside-operated Browse LNG development. Woodside has commissioned Fugro
to undertake a detailed seabed mapping programme extending offshore from the proposed central processing facility that will provide high quality data to assist with the engineering process for the proposed subsea pipelines and other infrastructure as part of this major project.
