Laser sensor tech provides huge potential for maritime industry

The LADAR system uses narrow laser beam scans, providing a full 3D perspective, accurate and real-time surveillance of the ocean including the problematic ocean surface layer. The LADAR system uses narrow laser beam scans, providing a full 3D perspective, accurate and real-time surveillance of the ocean including the problematic ocean surface layer.

Research scientist and entrepreneur Sverre Dokken believes laser-based remote sensing has big potential in the maritime domain and could reduce navigational risk by up to 50 per cent.

{mprestriction ids="1,2"} Laser Detection and Ranging (LADAR) is a laser-based navigational aid that combines long-distance object detection with high-accuracy measurement, giving users a full 2D/3D/4D (3D plus time) perspective for optimal maritime awareness.

The laser pulse scans a specific area or target with over 100 readings per second. Its water-penetrating capabilities enable very high-resolution detection of objects in the surface layer up to approximately one nautical mile (1.85km) distant and up to 10m deep in ideal conditions. “Objects” can be anything from a person, floating container, icebergs, whales, or small craft to environmental factors such as waves or pollution.

The modular design incorporates technologies such as laser diodes together with optical camera, gyros, optional AIS, and/or radar and sonar feeds to produce a comprehensive analysis of the ocean surface layer ahead of a vessel.

LDR principal Sverre Dokken, explained: “The system’s proven capability to detect, characterise, classify and track various surface-layer objects in real-time make it suitable for a wide variety of applications.

“The system overlaps many existing ship radar functions with added benefits, high-speed operation and no latency.”

The system can be configured to different light bandwidths as required.

LADAR, radar, and sonar

LADAR outperforms both radar and sonar through its ability to detect both smaller and larger objects in the surface layer. Sub-metre resolution at close and long range and 1000-times better resolution in azimuth and elevation than both radar and sonar also enable detection of very small objects. The system is independent of speed meaning it can be used on high-speed vessels, while it can also be mounted on any kind of stationary platform.

Data is visualised on an intuitive, customisable graphical user interface (GUI) enabling seamless transition from above-surface, through-surface and below-surface observations. Machine learning helps to continuously improve detection and classification capabilities. Users can also experience the “live” environment using Virtual and Augmented Reality (VR/AR).

Data feedback can optionally activate functions such as safe re-routing around navigational hazards, wave spectrum and ocean current observations, charting of marine plastic pollution, uncharted reefs, shoals, moving sand-banks, and so on.

“Our research indicates it can increase safety with a potential 50 per cent reduction in navigational risk. That means fewer dry-dock visits due to accidents and collisions, reduced costs and extended vessel lifetime,” said Dokken.

LADAR can also plug the sensor gap with large amounts of situational data as the industry moves to autonomous operations and e-navigation. LDR is also working on matching the system with drone technology.

“We’re convinced the generalisation of this technology will see new applications still unknown to us.”

Dokken said that there are no other laser sensor solutions in the market offering the same kind of performance as they are often bigger, less adaptable, and have less range.

Performance testing

The LDR lab continues iterative electronic and mechanical assembly to further reduce the size, weight and production cost of the system. “We also focus on performance testing both in the lab and in live settings,” said Dokken. “Last summer, for example, we were in the Mediterranean doing tests on plastic detection with very positive results.”

LDR has conducted trials onboard the cruise ferry Color Magic along its route between Oslo and Kiel, as well as proving its use in fish inventory assessment, bathymetric/sea floor mapping by aircraft and floating mine detection for a navy.

The company currently has LOIs in place with the likes of Team Tankers Management, Hurtigbåtforbundet HRF, The Fjords, GOTA Ship Management, Hargun Havfiske, Barents Nord, the Port of Rotterdam and Grand Large Yachting.

Dokken’s team have been perfecting their advanced LADAR sensor technology for some years now. The company was spun off from an EU-funded project that produced an early prototype.

“Our LADAR team have 100 years’ combined expertise in sensor systems, software and electrical engineering,” said Dokken. “We also cooperate with several experienced sea captains to ensure the system meets end-user needs and to keep tabs on market trends.”

    Kongsberg Digital is developing cloud-based simulation technology to support advanced operational studies, research and education in the maritime industry. The use of increasingly advanced equipment and an elevated focus on safety and sustainability has raised the bar for innovative new solutions to collect, simulate and share data to assist in optimisation of vessel operations.

  • Voyager PLANNING STATION gets major update

    Voyager Worldwide has announced a major upgrade to its Voyager PLANNING STATION navigation software. The new version features enhanced automation of route and passage planning, information sharing between ship and shore and new interactive guided workflow processes to reduce operational risk and streamline navigation processes.

    Voyager PLANNING STATION now automatically delivers digital and paper Notices to Mariners on board as soon as they available. Updates are transmitted via a secure link direct from Voyager Worldwide straight to the Voyager PC onboard to ensure vessels always have the latest information and prevent compliance issues.

    To complement the new fully automated update process, the size of the quarterly AVCS Admiralty Information Overlay update has been reduced by more than 85 per cent from 25MB to an average of 3MB to make ECDIS updating easier, faster and more cost-effective. The result is very simple fully automated electronic delivery of all updates and New Editions and smaller, more cost-effective data downloads that, together, remove any residual need to send physical CDs or DVDs to ships.

    “With its new levels of automation and enhanced user experience, this new version of Voyager PLANNING STATION provides comprehensive visibility of vessels against their planned routes and seamless distribution, updating and management of the data needed for e-Navigation. The result is better operational oversight that helps ship managers to safely and more efficiently manage their vessels and provides a faster, easier way for the bridge team to meet PSC and vetting requirements,” said Voyager Worldwide CEO, Kent Lee.

    In addition, a new built-in port to port routeing function enables users to select their departure and arrival port and generate a route. Routes automatically appear on either ENCs or Voyager’s integrated GIS map making it easy to refine waypoints to meet specific voyage requirements before clicking to identify and order the ENCs and other products needed for safe and compliant passage.

    For shore-based users who want to more clearly understand vessel status compared to the planned voyage, the enhanced Route sharing module now automatically uploads saved routes to Voyager FLEET INSIGHT, Voyager Worldwide’s web platform to allow ship management to monitor vessels on a 24/7 basis. Using Voyager FLEET INSIGHT, vessels can be monitored on a PC in the office as well as on the go via a tablet and smartphone.

    To provide better visibility of vessels’ compliance status and help reduce ECDIS and ENC related PSC observations and deficiencies, Voyager PLANNING STATION also now shows the details of when the ECDIS was last updated and shows when updates have not been applied. Voyager FLEET INSIGHT also enables vessels’ ENC, paper chart and publication orders to be viewed as an overlay on planned routes to enable more efficient order checking and approval and help reduce unnecessary purchasing.
