MBES Training Course Completed

In August 2012, UK-based Swathe Services & HydroCharting delivered the first in a series of new multibeam echo sounder (MBES) training courses designed to give hydrographic surveyors hands-on experience on how to set-up, interface, calibrate and operate MBES equipment. This, combined with in-depth training on QPS QINSy and Qloud, resulted in surveyors gaining valuable knowledge and experience which enabled them to undertake MBES surveys independently. This first course was also supplemented by the provision of equipment and first-class instruction from Adrian Gibbon from Applanix and Ben Dean from C-NAV who both gave classroom-based lectures and on-water instruction on how to...

Improving MBES Measurements

HYDRO 2006 Best Student Paper
In dynamic water environments such as the Maasgeul waterway off the Dutch coast at the Port of Rotterdam, tides and a varying presence of salt and freshwater from river run-off can cause considerable variation of the water column sound speed profile (SSP). It is important to adequately correct bathymetric data for sound refraction effects in the face of limited SSP information. A new approach, described here by case study, requires and exploits the multi-beam echo sounder (MBES) in surveying adjoining swathes with overlap. To maintain safe passage of ships along the waterways leading to the Port of Rotterdam, water depth... (read more)

Jan de Nul to Operate NORBIT MBES

NORBIT has secured orders from Jan De Nul Group, through its Benelux dealer Seabed BV, for several tightly integrated all-in-one turnkey multibeam sonar systems. These compact survey systems allow for fastest set-to-work on any size of survey platform while allowing for highest-quality broadband FM data from a forgiving curved receiver array. The systems each include a full inertial navigation system and surface sound speed probe and only one cable from the wet end to the small splash-proof topside. Norbit is conducting demos aboard the AHOY Freedom during OI 2016, taking place in London from 15-17 March, where the iWBMS is being showcased... (read more)

MBES-training Using a Remotely Operated USV

Swathe Services, a Hydrographic survey support company in Hayle, Cornwall (UK) ran the world’s first Multi-Beam Echo-Sounder training course using a remotely operated Unmanned Surface Vessel. People came from as far afield as Norway, France, Slovenia, UK and the USA to attend the intensive 5-day course. As part of the training, the delegates mapped Hayle Harbour in Cornwall using an Unmanned Surface Vessel fitted with Multi-beam Echo-Sounder technology. The USV was remotely operated from Swathe Services offices nearby using dedicated survey data acquisition software from HYPACK. Hands-on Training Kordula Schwarzwalder, a Researcher from the Norwegian University of Science and Technology,... (read more)

MBES and Laser Scanning Training Course

In January 2014, UK-based Swathe Services will be working with Hydrocharting to run a multibeam echosounder and MDL laser scanning training course with QINSy software. This training course offers hands-on training with high-spec hydrographic survey equipment and will be conducted by experienced trainers with 3 days of boat-based training and 2 days of post processing. The 5-day course will be held in Southampton, UK, starting on Monday 27 January 2014 and finishing on Friday 31 January. Training will be given by James Williams of Swathe Services and Jesper Højdal of Hydrocharting using SONIC 2020 and SONIC 2024 multi-beam echosounders alongside... (read more)

Portable MBES Hydrographic System Installed at Corsica

MacArtney France has delivered a portable Multi-Beam Echo Sounder Hydrographic System, designed for small vessels, to the French government organization, Collectivité de Corse, in Corsica, France. This bathymetric system will reduce survey time, increase accuracy, expand survey area reach and ensure a comprehensive hydrographic survey system. Secure navigation The purpose of the MBES Hydrographic System is to ensure visiting vessels can securely navigate the harbours of the island, monitor the seabed to control the quality of dredging, identify obstructions on the sea floor and finally verify underwater installations, for example, the quaysides and hexapods of the Corsican harbours. Meeting standards... (read more)

Port of London Authority Demonstrates MBES Technology at Ocean Business

The Port of London Authority (PLA) has increased their Multi-beam Echosounder (MBES) technology for hydrographic surveying of the Thames waterways with the purchase of a second R2Sonic 2024 MBES, supplied by Swathe Services. Demonstrations at Ocean Business As well as survey operations by the PLA, the Thame and its systems are heading to the industry event, Ocean Business on 9-11 April, Southampton, UK, where R2SONIC will conduct daily MBES demonstrations. The R2Sonic 2024 will be fitted to their newly converted hydrographic survey vessel Thame to support the range of survey tasks undertaken by the busy PLA Hydrographic Service. Regular surveys...

It All Starts with Hydrographic Charting

Three years ago large coastal hydrographic charting-based projects had become globally prolific. Thanks to the reliability of modern technologies and methodologies, such larger programmes were not only doable, they had become preferable and were even moving toward 'routine'. Today we can identify a similar trend related to multiple, diverse deepwater applications of large-scale programmes that all rely on MBES-based hydrographic charting applied regionally. The examples presented here demonstrate how large-scale, precision MBES-based programmes are being applied to deepwater studies far beyond improving navigation charting and safe navigation goals.

Three years ago we discussed the global proliferation of large coastal hydrographic charting-based projects. The main theme being that modern technologies and methodologies have become so reliable that these larger programmes were not only doable, they had become preferable and even moving toward ‘routine”. Today we can identify a similar trend related to multiple, diverse deepwater applications of large scale programmes that all rely on MBES-based hydrographic charting applied on a regional scale.
