Zupt Last-minute Addition to OI

Not wanting to miss out on Oceanology International in London's ExCel Centre from 13 to 15 March 2012 after all, Zupt, USA, has recently confirmed it will be exhibiting its latest technology relating to inertial metrology and ROV communications at stand no. K15. Zupt’s C-PINS can save marine construction survey project time and money. The technology has delivered more than 26 inertial metrologies and has completed sparse LBL and USBL smoothing operations in West Africa, the North Sea, the Bahamas and the U.S. Gulf of Mexico. The Micro-TTU can solve ROV serial communication issues. Micro-TTU adds six channels to any... (read more)

Wideband Signals the Future for Acoustic Positioning

The high accuracy and availability of GPS has enabled the offshore survey community to deliver benefits to customers and fuelled demand for a corresponding improvement in subsea acoustic positioning systems. This paper describes the benefits of Sonardyne International’s implementation of the same Wideband signal processing techniques that are used in GPS and discusses the fundamental difference between GPS measurement processes and acoustic positioning systems. Narrowband Limitations Until recently the majority of acoustic positioning systems used narrowband toneburst signals and analogue signal processing methods which have suffered from weaknesses: a limited number of operating channels, susceptibility to noise and interference, and...

Industry Brings Innovation to Inspire the New Generation

Looking Below the Surface and Seeing What Lies Ahead
For the fifth year in a row, the Lake Survey was held in the Netherlands. This year Teledyne CARIS collaborated with Boskalis and Fugro in a one-week all-encompassing practical survey week. From 26 to 30 June 2017, 14 students worked with some of the most advanced equipment and technology that is currently available in the market. The organising committee had prepared a week with a varied programme. Practical sessions, demonstrations and presentations covered various subjects that the students are likely to encounter in their professional careers. After 5 days full of mobilisation, calibration, demonstration, information, innovation and recreation, it was... (read more)

Bionic Solutions for Underwater Communication

EvoLogics GmbH, Germany
EvoLogics GmbH is a private high-tech enterprise with headquarters in Berlin, Germany. The company designs and manufactures underwater information and communication systems, as well as hydroacoustic sensors. Its core values are rooted in bionic concepts that combine state of the art engineering with the best ideas found in nature. EvoLogics was launched in 2000 with a small group of scientists and R&D experts, aiming to develop innovative technologies for maritime and offshore industries. To solve the common problems of transmitting data underwater, the team turned to dolphins - the ocean’s ’talking nation’ - known to use a wide variety of... (read more)

Order for NASNet in Norwegian Offshore Field

Nautronix, UK, has secured an order to supply NASNet, an underwater positioning system, for Subsea 7. The system will be used on the Aasta Hansteen field, which is located in the northern part of the Norwegian Sea approximately 300km west of Bodø, at 1,300m water depth. The field is developed by Statoil. Nautronix will be supplying 16 Large Stations and 4 complete vessel systems which will go on hire in March 2015 for approximately 200 days and will be deployed for the first time in Norwegian waters where the water depth is significant and the weather conditions can be challenging....

Zupt and Sagem Working Together

Zupt, USA, has entered into an agreement with Sagem (Safran) for the development of the subsea hydrographic and oil & gas market for the Sagem BlueNaute product range. This will include standard subsea heading, pitch, roll and heave products as well as aided inertial options (USBL smoothing and Sparse LBL) to be combined within the subsea BlueNaute products. BlueNaute is based on hemispherical resonator gyros (HRG), a patented Sagem (Safran) technology that was initially used in spacecraft. This new‐generation inertial navigation system is already used in aerospace, which has very demanding reliability requirements. BlueNaute has been developed to be fully... (read more)
