instrumentation to optimize behavior and performance. The solution was delivered using a broadband data link from the seatooth family of subsea wireless instruments from WFS, enabling a high rate of data to be transmitted over a short range, underwater. Seatooth can provide a reliable wireless communications link in the most challenging subsea environments: •    In shallow water or turbid water •    In the presence of bubbles or contaminants •    Near to large subsea structures •    Through ground, seabed, concrete

GMG Secures Cable Contract for Rampion Offshore Wind Farm

Marine Group (GMG) announced that it has been awarded a contract from E.ON to install a fibre optic cable at the Rampion Offshore Wind Farm, under construction 13km off the coast of Sussex, UK.   Upon completion the cable will run from the shore to an offshore substation, providing a vital communications link for this major wind farm. The installation is expected to be completed later this month.   CWind, which is part of the GMG and is responsible for delivering the Company’s power capabilities, will execute the contract and will utilize the Group’s capable assets and project

WFS Tests Wireless Subsea Modem

A new wireless subsea modem has been trialed at The Underwater Center, a subsea testing and training facility in Fort William, Scotland. WFS Technologies trialed the Seatooth S100, a mobile, wireless subsea modem suitable for a variety of underwater applications from 100m - 4000m. The modem is designed to provide a reliable digital wireless communication link or logging device up to 5m range, even in challenging deep water conditions. It is equipped with standard data communication interfaces, making it suited to sensor and underwater vehicle applications. It can be deployed swiftly on temporary or

WFS, Nustar and Precision Enter Collaboration

WFS Technologies (WFS), NuStar Technologies and Precision are pleased to announce an agreement to offer a subsea wireless datalogging system to support flow metering for JAMSTEC, the Japan Agency for Marine-Earth Science and Technology. The project being led by NuStar Technologies involves cultivation and extraction of rare earth minerals in Japanese waters at sea depths between 1,600m and 3,000m. WFS will supply a SeatoothS100 datalogger to be used to log mineral rate data from a Hoffer flowmeter. SeatoothS100 is a compact, low-power, wireless modem, data logger, multiplexer and controller.

. Microwaves are defined to operate in the 300MHz to 300GHz frequency range; the other technologies applied in the field of underwater communication typically operate at far lower frequencies, and correspondingly lower data rates. Data speeds of kbps (kilobits per second) are possible with acoustic communications. Radio-frequency communication links (within the 3 KHz to 300 GHz range) are able to achieve similar data speeds over some meters. Inductive links used for power transfer are often also used for data transfer, with small separation between frequencies, which presents some risk of interference

and it had to be simpler to install and maintain.   The team designed and developed a prototype ADCP system consisting of a single buoy-mounted component that automatically transmits data using real-time telemetry via an Iridium satellite. The new approach eliminates the less reliable radio communications link and the entire data-receiving shore station employed by the old system.   Together, these improvements will reduce costs for PORTS partners by an estimated one-third or more. The satellite transmission also does not have a range limit, so current sensors can be placed on virtually any

Bibby Offshore Clinches BP Contract

  Bibby Offshore, a leading subsea services provider to the oil and gas industry, has been awarded a multimillion pound contract by BP to replace subsea infrastructure in the Central North Sea.   The work is part of the $1billion Eastern Trough Area Project (ETAP) Life Extension Project announced by BP in the summer. ETAP is one of the largest and most complex developments in the North Sea, comprising nine oil and gas reservoirs, six of which are operated by BP. The ETAP Life Extension Project (ELXP) will help secure the future of the fields until 2030 and beyond.   The Bibby
