Unmanned Technology Unveils the Mystery of Antarctica

USV Fills Data Gap for Polar Expedition
Not long ago, China’s fifth Antarctic scientific research station – the Ross Sea Station – officially laid its foundation stone on Inexpressible Island (74°54’S 163°39’E). While preparation and research already began a few years ago, the construction work will take another four years to fully complete. In November 2017, four unmanned surface vessels (USVs) from Oceanalpha Co., Ltd teamed up with the Antarctica expedition ship ‘Snow Dragon’ all the way south to the Ross Sea to assist the construction project. The USVs worked for nearly 40 hours, completing a multibeam full-cover seabed topographic survey of five square kilometres. This not... (read more)

USVs to be Used for Wide Area High-resolution Surveys

ASV Global, UK, is to design and build six brand new Unmanned Surface Vehicles (USVs) for SeaTrepid DeepSea. The vehicles will be used in a multiple autonomous vehicle programme developed by SeaTrepid DeepSea combining USVs and Autonomous Underwater Vehicles (AUVs) to conduct wide area, high-resolution surveys. Derivatives of the ‘C-Worker’ range of ASV Global platforms, the new bespoke ‘SeaWorkers’ will each be fitted with an acoustic underwater positioning system to track the AUVs throughout shallow and ultra-deep waters. Using USVs to track the AUVs brings a step change in operational efficiencies with significant cost savings compared to using a traditional... (read more)

Inspector MK2 Links Unmanned Systems

ECA Group has extended the capabilities of its unmanned surface vehicle (USV) Inspector MK2 to provide faster data transfer and docking linked to other unmanned systems such as USVs, ROVs and AUVs. Premium equipment has been selected and tested in real user conditions to complete and qualify ECA Group's radio communication solutions for its USV range. Featuring this new capability, the unmanned surface vehicle Inspector can be used as an intelligent docking system for underwater drones systems such as AUVs or ROVs, allowing them to be automatically deployed and recovered: it enables recharging and data download, as well as fast transits....

30th China Ocean Surveying and Mapping Academic Seminar

The 30th Ocean Surveying and Mapping Academic Seminar was held in Zhuhai on 29 August. The event was hosted by the Ocean Surveying and Mapping Committee of the China Society of Surveying and co-organised by Oceanalpha Intelligent Technology. The conference attracted nearly 200 delegates, including representatives from the Ministry of Natural Resources, the Ministry of Transport, the Ministry of Water Resources, the Chinese Academy of Sciences, the Navy and manufacturers of surveying and mapping instruments. Joint operation of USV, multibeam echosounder and 3D scanner On 31 August, the participants visited Oceanalpha’s unmanned vessel base and watched a demonstration of surveying... (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)

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)

Securing Offshore Oil and Gas Infrastructure with USVs

Employing commercial-off-the-shelf USVs that can be rapidly reconfigured with a diverse range of sensors can enhance the ability to deliver energy to America and the world. This is a win-win for the energy industry, says George Caldorisi when he describes the securing of oil and gas infrastructure with Unmanned Surface Vehicles. While the exigencies of climate change have led to major strides in the development and deployment of renewable energy sources such as solar, wind and others, the world’s energy needs will continue to be met primarily by oil and natural gas for the foreseeable future. As readers of Hydro International are well aware, the strategic implications of the United States’ transition from energy dependence to energy independence to becoming a net oil and gas exporter are being felt worldwide. While some saw this sea change coming, most did not, and the community of nations is still coming to grips with... (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)

New Robotic Survey Techniques to Monitor Changes in the Port

Hayle Harbour Authority has partnered with Unmanned Survey Solutions (USS) to help with the development of robotic vessels in performing hydrographic surveys in Hayle Harbour, Cornwall, England.  The aim is to monitor the effects of dredging, sluicing and periodic natural changes to the depths of the harbour in fulfilment of its conservancy requirements, and ensure safe operation to harbour users. Unmanned Survey Solutions (USS) are based on North Quay, Hayle. They design, build and operate Unmanned Surface Vessels (USVs) or ‘robotic boats’ and are often out testing new systems in local waters with permission from the Harbour Authority. During these...
