Saab Seaeye AUV Demonstrated at Lake Vättern

For offshore operators, a 4D geospatial data acquisition system with real-time data visualisation is now available for the Seaeye Sabertooth AUV. Its full capabilities were demonstrated to representatives of 12 companies from seven countries, together with the Danish Navy, in Saab’s exclusive underwater test centre at Lake Vättern, Sweden. This system has been configured for the Sabertooth by Saab QPS, a Saab Seaeye partner and leading developer of hydrographic survey and mapping software. Operators get a complete hydrographic data acquisition, navigation and processing software package that is fully integrated into the Sabertooth.  The development unifies the QINSy and Fledermaus systems...

ECA to Conduct AUV Autonomous Inspection Sea Trials in the Deepwater GoM

The offshore sea trial using the Alistar 3000 Inspection AUV was designed by BP to evaluate the technology. It will be located in the company’s deepwater King Field (1700msw) in the Gulf of Mexico and will comprise the following three levels of trials: Passive pipeline inspection: Alistar 3000 will locate and follow a pipeline at various altitudes above the pipeline whilst recording video, sonar data and actual position of the flowline. Active pipeline inspection: Alistar 3000, using on-board sensors that can automatically detect anodes or anomalies whilst tracking the flowline, will actively modify its mission to carry out closer General...

Two Additional Gavia Offshore Surveyors for UTEC Survey

Teledyne Gavia from Iceland has received an order for two additional 1,000m depth-rated Gavia Offshore Surveyor Autonomous Underwater Vehicles (AUVs) to UTEC Survey (USA). The UTEC Gavia AUVs are fully equipped for geophysical surveys in near-shore environments out to 1,000 metres. The vehicles are fitted with swath bathymetry, sidescan sonar, subbottom profiler modules and a depth-rated camera with strobe lighting. The two most recent vehicle purchases come with the DVL aided ROVINS154 Inertial Navigation System module (iXBlue, France), providing a high accuracy INS in a package that is not of US origin so it does not automatically come under the...

First Gavias AUVs for Oil and Gas

An order has recently been placed by NCS Survey for two Gavia AUVs with a capital expenditure of GBP1.5m - one 500m-rated system and one 1,000m rated system. These systems are specifically aimed at the shallow water market and are understood to be the first Gavia AUVs to enter the Oil & Gas market as a service provided by a survey contractor.     In doing so, Hafmynd, the Icelandic manufacturers, has created a new line named the Gavia Offshore Surveyor. Delivery is expected in late September this year but NCS Survey have already secured a contract, which started in... (read more)

Hydrographic Society Benelux

Workshop on Technical Developments During ­Europort As a side-event to Europort 2013, the Hydrographic Society Benelux organised a workshop matching the theme of the event ‘Pioneers in Maritime Technology’. The event was opened by Oystein Aasbo of Kongsberg Maritime Norway, giving a fascinating insight into new operational features of AUVs and what the future might bring. He predicted that some tasks such as Inspection, Maintenance and Repair, and positioning seismic bottom nodes, now often carried out using ROVs, could be performed by AUVs. He also showed the new Kongsberg Munin AUV and its features. Martin de Kievit of Trimble, the... (read more)

RS Aqua Prepared for OI 2014

UK-based RS Aqua will be showcasing many new products during Oceanology International 2014, to be held from 11 to 13 March 2014 in the ExCeL Centre, London. The following featured items represent the major developments being highlighted at Stand F550 during the three-day event. The Rosemount WaveRadar division at RS Aqua will be launching a new remote data telemetry facility at Oi14. The WaveRadar offshore wave, tide and air-gap system has been enhanced by the development of an integrated wave data collection, processing and telemetry solution for remote wave monitoring. This new system connects the WaveRadar REX sensor directly to... (read more)

Technology in Focus: Inertial Navigation Systems

Bridging the Positioning Gap
Inertial Navigation Systems (INSs) are a great help in applications where either position stability is of great importance or where bridging (small) positioning gaps is a requirement. To understand INS, imagine you are standing blindfolded in the centre of a long hallway. Then you start walking. You may proceed quickly at first, compensating as needed and covering ground with confidence. Eventually, however, you begin to lose your sense of alignment. This ability to successfully navigate when denied a visual frame of reference, even for a relatively short amount of time, represents our own basic human form of inertial navigation. An...

Workshop on Underwater Positioning

The Hydrographic Society organised a workshop on underwater positioning and navigation on Wednesday 10th December 2008. On board of the tug René Siegfried, three presentations were held, touching various aspects of the matter.   Hans-Willem de Leeuw (sales engineer, IXSEA Benelux) explained the principle of the fibre optic gyroscope and introduced various applications of this technique in the IXSEA product range. Especially in the offshore, there is a demand for precise underwater navigation and the combination of the fibre-optic gyroscopes with GPS or DVL make the positioning more accurate, even after hours.   Neil MacDonald (technical manager, Applied Acoustics) went...
