Next-generation USV to Launch at Ocean Business 2019

Unmanned Survey Solutions (USS) has designed and built the next-generation Accession Class Unmanned Survey Vessel (USV) for use in nearshore and offshore hydrographic surveys. The device will launch at Ocean Business in April 2019. The unique modular design of the USV allows the vessel to increase its base design length of 3.5m to a maximum of 5m for additional payload equipment and/or power for extended endurance depending on operational requirements. James Williams, director at USS, said “We wanted to build a USV that was truly versatile, reliable and robust enough to withstand operating in offshore conditions while keeping it simple...

Emerging Trends in Bathymetric Lidar Technology

What is on the Horizon for Airborne Lidar Bathymetry?
A surging interest in remote sensing and analytics has seen technology developments linked to these domains take off as we head into 2019. Airborne Lidar bathymetry (ALB) is no exception to recent innovations, especially with the growing recognition in the importance of high-resolution data to inform management of our oceans, seabed and coastal zones. In our recent discussions with ALB manufacturers and experienced operators, several significant new developments were revealed. The new developments include: Lightweight ALB sensor alternatives driven by the proliferation of Unpiloted Aerial Vehicles (UAVs) Increased point density for ALB across all feasible depths for improved detail and...

Hydrographic Surveying: Where Do We Stand

The Ever-increasing Accuracy of Mapping the Surface Waters
Hydrographic surveying is highly specific and requires a suite of advanced acquisition and positioning sensors attached to a mobile survey platform as well as sophisticated software to allow the correct combination of all the data. For those within the industry, the advances over the last decade may feel more like an evolution rather than a revolution. If we look back one, two or even three decades, we can see the enormous leap hydrographic surveying has taken. Where do we stand, and what can we expect for the near future? In this article, we will look at the present compared to... (read more)

Optimising Workflows on the Maritime Information Highway

Expanding Operations Over the Horizon
By providing vessel-to-vessel and vessel-to-shore communication independent of satellite or cellular networks, the Maritime Broadband Radio (MBR) system from Kongsberg introduces possibilities to transform survey operations. Potential applications include delivery of raw data to shore and providing a communication and remote-control channel for multiple survey launches and unmanned surface vessels in a single operation. MBR is designed to connect operational assets and teams by delivering high-performance and barrier-free communications, without the need for expensive infrastructure. This enables the system to unlock a new age of collaboration for complex operational tasks. A MBR network can securely carry a diverse array of... (read more)

World's First Fully Autonomous Hydrographic Survey

No Line Plan, No Boat Crew, Just Sensors
During September 2017, the world’s first autonomous hydrographic survey was performed. 'Autonomous' means not by remote control, but rather that the autonomous surface vehicle (ASV) used guidance from survey software to run pre-planned survey lines or automatically generated lines based on sonar coverage, with human interaction possible but not required. The Channel Coastal Observatory (CCO) commissioned 4D Ocean to undertake a hydrographic survey of the seabed offshore of Hurst Spit, Western Solent, using a SeaRobotics ASV 2.5. The pilot survey was supported by the Maritime & Coastguard Agency (MCA) and UK Hydrographic Office (UKHO). By Duncan Mallace, contributing editor, Hydro... (read more)

OSRL Tests and Validates Remote Sensing Equipment

A recent offshore exercise, conducted by Oil Spill Response Ltd. (OSRL, UK), was designed to understand how remote sensing technologies can help detect oil spills at sea more effectively. Utilising the latest in satellite, airborne and in-water surveillance and communications equipment, the successful event demonstrated the value of the technology in identifying and monitoring spills and was conducted with full approval of the Marine Management Organisation (MMO) following a rigorous planning and stakeholder consultation process. The main surveillance tools and providers involved in the exercise included: Radar and optical satellite imagery (MDA, Earth-I, Airbus, Telespazio) Infra-red and Ultraviolet sensors on... (read more)
