Robot vision technology aids offshore lifting

Sparrows Group and OptiLift have partnered to deliver technology that can improve the up-time of lifting operations

Sparrows Group has partnered with Norwegian firm OptiLift to deliver robot vision laser technology which aims to improve the up-time of offshore lifting operations.

Traditionally decisions about lifting in harsh weather are based on significant wave height. The technology being delivered by the partnership is OptiLift’s Motion Reporter. The technology collects real time vessel movements to identify the actual wave height on deck which can often vary by several metres on different parts of the vessel.

The technology works using a laser and camera that automatically generate 3D models of supply vessels without any sensors or instrumentation required to be on the vessel itself. The vision-guided laser measurement technology, combined with algorithms and software can enable control and non-contact measurement capabilities. The system measures the relative motion between the boom tip and the ship vessel, meaning that it works for cranes on stationary platforms and on floating and mobile units.

Having possession of this important data means crews can make informed decisions about safely continuing lifting operations and avoiding unnecessary costly delays, the company says.

As part of the agreement, Sparrows Group will distribute, install and maintain the Motion Reporter on behalf of OptiLift.

Stewart Mitchell, chief executive officer of Sparrows Group, said: “Joining forces with OptiLift significantly enhances our capabilities because they have developed a huge innovation in lifting technology. Motion Reporter could dramatically increase operational efficiency, especially in harsh environments where having the ability to mitigate the risk of the weather delaying your lifting operations is absolutely invaluable.”

Camilla Nylund, General Manager at OptiLift said: “The Motion Reporter can change the norm of lifting operations in harsh environments, allowing operators to undertake the loading and discharging of cargo quickly and securely, without having to wait for days to know it’s safe to do so.”
