A New Solution for Subsea Metrology

Combination of Acoustics and Photogrammetry
Invariably, metrology is required at the critical stages of field development and the main goal for improvement is to reduce the time taken for acquiring data. The technique discussed offers significant improvements in terms of time and required equipment. Offshore Construction During offshore construction several structures have to be interconnected by means of spools or jumpers. In order to determine the dimensions and relative attitudes of the connections, surveyors deploy ROV-mounted instrumentation. IMCA S019 Guidance on Subsea Metrology offers the following combined accuracy guideline: 50mm to 150mm in X,Y and Z axis 0.5° to 1° for relative pitch, roll and heading.... (read more)

Canadian Hydrographic Society

The Canadian Hydrographic Association (CHA) wrapped up another successful conference (CHC2014) in St. John’s Newfoundland and Labrador this past April. Partial proceedings are now available through the CHA website, www.hydrog­raphy.ca. Proceedings of the past several CHCs are also available through this site. Plans are underway for CHC2016 in Halifax Nova Scotia at the Westin Hotel from 16 to 19 May 2016 and CHC2018 in Victoria, British Columbia at the Empress Hotel from 5 to 8 March 2018. Lighthouse magazine, the journal of the CHA, is no more. With the publication of Edition 82, this brings to a close the more... (read more)

Hydromagic 6.0 Collects Millisecond-precision Data

Hydromagic version 6.0 has been released to the public. The entire data collection module has been rewritten. The software collects all sensor data with a millisecond-precision timestamp, resulting in more accurate soundings. While the previous version of the software was only able to produce soundings with 1 second intervals, this can be adjusted in the new version. The files containing this original data will never be altered. Instead the software tracks all changes in a separate project folder, so it is always possible to roll back to your original sounding data. Using this feature, the software is now offering support...

AquaPix Synthetic Aperture Sonar System for DRDC

Kraken Sonar Systems, Canada, has successfully completed sea acceptance testing of an AquaPix Interferometric Synthetic Aperture Sonar (INSAS) system for Defence Research and Development Canada (DRDC). Kraken delivered a dual-sided AquaPix INSAS2 system complete with an embedded real-time INSAS signal processing engine and two DataPod removable data storage modules. The CAD500,000 system was integrated into DRDC's Arctic Explorer-class autonomous underwater vehicle (AUV). DRDC is the national leader in defence and security science and technology. As an agency of Canada’s Department of National Defence (DND), DRDC provides DND, the Canadian Armed Forces (CAF) and other government departments as well as the... (read more)

BioSonics Cooperates with CADDEN

BioSonics, USA, and CADDEN, France, have signed an agreement that allows for support and service provided from CADDEN’s headquarters. This agreement will help to better serve BioSonics’ customers in Europe by providing closer proximity to technical support staff in local time zones. CADDEN personnel recently completed a factory training programme at BioSonics facilities in Seattle and are now authorised for BioSonics echosounder inspection, maintenance and field calibration. BioSonics president, Tim Acker, stated that CADDEN has developed several projects leading to the implementation of fixed-position automated monitoring systems in France. These more sophisticated systems benefit from local technical support and access... (read more)

Italian Surveyors Benefit from Eiva Training

RMS Submarine, UK, have recently supported and sponsored 2 weeks of back to back Eiva Navisuite training in Naples, Italy. The two 6 day courses were run during February 2014 for the benefit of 20 experienced Italian freelance surveyors (10 per course) who until now, had not had the opportunity to be exposed to the software suite. A mix of survey party chiefs, senior and junior surveyors, data processors, as well as GIS & CAD operatives attended the courses. RMS was approached to support the event and provide a competent lecturer, software support, training materials and course attendance certification. Computers... (read more)

Eye4Software Releases Hydrographic Survey Software Package

Eye4Software, The Netherlands, has announced that the latest version of its hydrographic survey package, Hydromagic version 5.2, has been released to the public. The main purpose of this software is to map the bottom of a river, reservoir or ocean in 3D, by using a (D)GPS or RTK positioning system combined with an echosounder or fishfinder. Once data acquisition has been completed, the sounding can, if needed, be filtered and corrected using the built-in sounding editor. The corrected sounding can be used to generate a number of final products, like a digital terrain model or DTM, volume calculation, cross sections,... (read more)

Hydromagic Adds Current Tide Level Calculation

Eye4Software’s hydrographic survey package, Hydromagic version 5.1, has been released. The software maps the bottom of a river, pond or ocean in 3D by using a (D)GPS or RTK positioning system combined with an echo sounder or fish finder. This version supports real-time calculation of the current tide level by using a RTK receiver connected to the PC. The tide is calculated using the antenna height, antenna offset and a geoid model. The tide level is then applied to the sounding, resulting in a height value relative to the local vertical datum. Another addition is the possible use of OpenStreetMap,... (read more)

Two New Hydrographic Survey Boats for the Congo River

The Alu Marine shipyard, France, has completed the construction of two survey launches for the Democratic Republic of Congo (DRC). This order was attributed to Alu Marine in spring 2012 following a public tender from the 'Congolaise des Voies Maritimes' (CVM). These survey boats will carry out hydrographic surveys in the maritime pound of the Congo River to guide dredging and marking for the DRC's Multimodal Transport Project. The project aims to improve transport connections between the east and west of the DRC, and thus develop trade and economic activity in this area. 150km of river are concerned, the distance...
