Topaz Energy and Marine has completed trials of the first ‘targetless’ dynamic positioning (DP) laser sensor by Wärtsilä, designed to improve safety and operational uptime.
SceneScan, which was developed by the Wärtsilä company Guidance Marine, is a high-accuracy rotating laser sensor that requires no reflector target. It provides positional information to allow automated approach and/or station keeping relative to a structure or vessel. SceneScan is straightforward to operate and provides tracking information relative to natural or man-made structures within the sensor field of view. It tracks by matching its current observation of the scene against a map generated from previous observations of the scene.
SceneScan was connected to a Wärtsilä DP system already installed onboard the Topaz Citadel. Tests were carried out over 90 days, with Topaz confirming at the end of the trial period that it is to keep the system installed on the Citadel and begin a roll-out to additional vessels.
The initial order includes upgrading existing DP sensor systems onboard four of the company’s vessels. Wärtsilä will also provide installation and commissioning of the systems.
Paul Jarkiewicz, operations director, Topaz Energy and Marine, commented: “The installation onboard the Topaz Citadel was seamless, and the technical support that was provided by Wärtsilä throughout the testing period successfully determined the system’s overall effectiveness. We have no doubt that the SceneScan system will add considerable value to the DP operations of our versatile and digitised fleet.”
Andrew Stead, head of business development, Guidance Marine, added: “The testing and evaluation was carried out and proven under actual DP operations with offshore platforms in the Caspian Sea. The positive feedback provides further evidence of the efficiency and accuracy of the SceneScan system. This is fully in line with Wärtsilä’s Smart Marine vision, for which enhanced vessel safety is a key pillar.”
