IMO takes the e-navigation reins Wartsila subsidiary Guidance Marine. It has tested SceneScan, its first targetless laser sensor for dynamic positioning (DP). It has also introduced short-range radar for intelligent navigation. Topaz Energy and Marine tested SceneScan on its DP class 2-capable platform supply vessel Topaz Citadel during a 90-day trial. Guidance Marine head of business development Andrew Stead says the trials were conduct on Topaz Citadel, offshore Azerbaijan, where Topaz operates a fleet of support vessels for oil major BP. “The testing and evaluation was carry out and proven under actual DP operations around offshore platforms in the Caspian Sea,” he says. “The positive feedback provides further evidence of the efficiency and accuracy of the SceneScan system.”

The tracking information is relative to natural or man-make structures within the sensor’s field of view and matches its current observation of the scene against a map generated from previous observations. Guidance Marine business development manager Sasha Heriot describes RS24 radar as a “ground-breaking development” that offers “unparalleled close-range fidelity, providing a level of situational awareness that is unprecedented in ship radars.” Rival technology group, Hexagon subsidiary Veripos, has secured a multi-year extension to provide precise positioning information to a global surveying company. Veripos supplies position reference information based on the Global Navigation Satellite System (GNSS) to subsea services group Acteon subsidiary UTEC.

Developments in position reference technology and sensors add safety to offshore manoeuvring

“As offshore operations are now encountering more incidences of intentional and non-intentional GNSS interference, our latest anti-jamming technology is design to ensure the highest levels of signal integrity,” he says. Marine & Industrial Plant can be mitigated by including information from more GNSS constellations in precision navigation and positioning products. GNSS can include data from GPS, Glonass, Galileo and Beidou constellations and other regional services.IMO will partner with others to further develop, harmonise and define e-navigation maritime services including:

  • Vessel shore reporting.
  • Search and rescue.
  • Communicating maritime safety information.
  • Telemedical assistance
  • Pilotage and tug services.
  • Telemedical assistance.
  • Meteorological and hydrographic information.
