contract for The Norwegian Public Roads Administration, Statens Vegvesen (SVV), to perform geophysical mapping of a 5km2 area in Bjørnafjord in Norway. The project was executed using the Hugin AUV Chercheur manufactured by Kongsberg Maritime and owned and operated by Canadian company Ocean Floor Geophysics Inc. (OFG) in combination with the small survey catamaran GeoCat owned by DOF Subsea Norway AS.The aim of the work was to obtain the necessary basis for engineering design services for a bridge over Bjørnafjord in connection with the Ferry Free E39 project. The assignment included high-quality

his research yielded, but in the quality and diversity of the questions he considered. An ethos he expressed throughout his career was for scientists to take risks, pursue new directions, and embrace the educational value of failure.“Walter Munk has been a world treasure for ocean science and geophysics,” said Scripps Oceanography Director Margaret Leinen. “He has been a guiding force, a stimulating force, a provocative force in science for 80 years. While one of the most distinguished and honored scientists in the world, Walter never rested on his accomplishments. He was always interested

It also has two joint ventures: Ocean Floor Geophysics, a subsea geophysical firm, which owns and operates AUVs with and has its own sensor development and data processing group; and Subsea Geo Services Inc., set up to operate Cellula’s seafloor drills on behalf of clients.(As published in the July/August 2018 edition of Marine Technology Reporter

Defense Research and Development Canada Upgrades its AUV

Ocean Floor Geophysics In. (OFG) said it was awarded a contract to deliver and install two Self-Compensating Magnetometer (SCM) systems to the Department of National Defense’s (DND) science and technology organization, Defense Research and Development Canada (DRDC), under the Built in Canada Innovation Program (BCIP).The systems, which are supplied with a specialized Subsea Processing Unit (SPU), will be installed on a shallow-water IVER Autonomous Underwater Vehicle (AUV) and a 5,000m depth-rated ISE Explorer AUV.The SCM system works by running a simple AUV calibration routine at the beginning

New Range of Underwater Connectors

Immersible connectors have to meet a variety of mechanical and chemical constraints. SOURIAU has been active in this market for a very long time, continuously adapting its product range to customer requirements in the field of military submarines, oceanography, geophysics and the oil industry. With SWIM, SOURIAU is launching a new range of connectors designed for new markets.The new SWIM range (Shallow Water IMmersion) is designed for marine applications in depths down to 300 m, which are considered shallow immersion. These connectors are designed for innovative applications like surface drones for

Fugro recently completed two site investigation campaigns for Ferrovial Agroman and Laing O'Rourke, the consortium undertaking construction of the project’s central section for client, Tideway. Over a seven-month period, work included drilling, downhole geophysics and testing to depths of 80 metres to provide ground risk and engineering data along a 10-kilometre stretch of the river. Efficiency in cycle-time and river transit in tidal waters was crucial in delivering information to suit the phasing of planning and design.
