The Growing Range of Uses for Unmanned Systems

Traditional manned survey vessels are often unsuitable, inefficient or incapable of completing a successful survey in challenging locations. In nearshore areas that are difficult to reach for ships and their launches, for example, attempting to conduct hydrographic surveys can pose hazards to both personnel and equipment. Unmanned systems offer a feasible solution in such situations. Unmanned systems can be subdivided into remotely operated underwater vehicles (ROVs), autonomous underwater vehicles (AUVs) and unmanned surface vehicles (USVs). At Hydro International, we have selected a series of articles providing hydrographic surveyors with essential insights into the various application areas for unmanned systems. USVs... (read more)

Unmanned Surface Vehicle as Aid for LBL Positioning

EvoLogics Explores New Applications for its Sonobot USV
The market of unmanned surface vehicles (USVs) is expanding, with more and more remotely controlled and autonomous USVs becoming available as commercial products. While environmental monitoring and data collection remain the primary target for lightweight USVs, EvoLogics recently tried out a rather untypical, but very promising approach for using its Sonobot: the vehicle turned out to be well suited for calibration and testing of long-baseline (LBL) positioning systems, opening a wide range of new applications. A typical LBL underwater acoustic positioning system uses an array of at least three seafloor-mounted transponders that form the system’s baseline. Before putting the system... (read more)

XOCEAN Expands with Acquisition of Survey Specialists 4D Ocean

British ocean data company, XOCEAN, announced last week that it has completed the acquisition of 4D Ocean, a specialist autonomous hydrographic survey company, as part of the company’s strategic global growth plans. The announcement follows the news of XOCEAN’s successful €7.9 million funding round earlier this month. XOCEAN is transforming the way ocean data is collected using marine robotics known as Unmanned Surface Vessels (USVs). The company has recently delivered projects for clients including BP, Equinor, PX Group and the UK’s Maritime and Coastguard Agency. The services provided by XOCEAN include mapping the seabed, inspecting subsea structures and monitoring the... (read more)

Unmanned Surface Vessel Presented

Sirehna is presenting its Unmanned Surface Vessel: Rodeur. Based on a 9.2m RHIB platform, Rodeur is a fully autonomous surface vessel adapted to many missions. With full range of control modes: remote joystick, track keeping, station keeping and obstacle avoidance, the Rodeur is operational for a wide range of applications like oceanographic survey, pollution/chemical detection, etc... Rodeur is available for testing of  equipment in real sea conditions and if you already have a platform, please notice that a USV robot kit  is available to drive your own USV platform! For more information, Sirehna is available booth 70.   (read more)

3 Unmanned Surface Vessels Operated Simultaneously

Ocean Infinity, the seabed survey and ocean exploration company, will be supporting its partner Guardian Geomatics on an extensive hydrographic project for energy company Shell. The project, which is planned to commence in June 2019, will be run from Ocean Infinity’s ‘Seabed Constructor’ vessel and will collect hydrographic data over an area in excess of 800 square kilometres using up to three Ocean Infinity unmanned surface vessels (USVs). Operating Multiple USVs Oliver Plunkett, Ocean Infinity’s CEO, said: “Our ability to utilize multiple USVs simultaneously to collect data across such a vast area, in such a short space of time, and...

Unmanned Mapping of Ultra-shallow Waters

Tarragona Survey of the Riu Francoli Using an USV
Hydrographic surveying in ultra-shallow, inland and enclosed waters can prove extremely challenging and often presents increased risks and obstacles to both personnel and equipment. These considerations include health and safety issues, potential damage to equipment, lack of suitable launch sites and regions where submerged debris and physical seabed characteristics can make an area particularly hazardous to survey. In these locations, traditional manned survey vessels are often unsuitable, inefficient or incapable of completing a successful survey. In November 2016, Unmanned Survey Solutions, with support from Swathe Services, was tasked with completing a hydrographic survey of such an area.  Survey Layout Located... (read more)

National Oceanography Centre Confirm Order for ASV C-Enduro

The National Oceanography Centre (NOC), Southampton, UK, have confirmed the order of an ASV C-Enduro. The announcement was made at the Long Endurance Marine Unmanned Surface Vehicle Showcase at NOC on Friday 6 June 2014. NOC will use the USV for oceanographic data collection over extended periods of time. The purchase comes as UK Science Minister David Willetts announces Robotics and Autonomous Systems as one of the ‘Eight Great Technologies’ to be supported by Government. C-Enduro was initially developed under an SBRI initiated by NOC’s requirement for a long endurance USV for environmental research. The project was co-funded by the... (read more)

NORBIT Multibeam System for Emma Rentals

Peter Eriksen of NORBIT delivered a NORBIT iWBMS system for Emma Rentals during Oceanology International 2016. The iWBMS is the tightest-integrated high-end multibeam echosounder with built-in GNSS/INS. Several jobs have already been contracted by Emma Rentals, both for inland waterways and off the Baltic coast. The NORBIT iWBMS system including the Applanix Wavemaster 2 OEM GNSS/INS will also serve as an important asset for Emma Technologies' research activities within the field of advanced backscatter processing.
