Its detection accuracy reached 0.01 degrees, providing a “smart eye” for underwater cable-laying operations and pushing the level of intelligence in such equipment to a new level. As the core equipment used for underwater cable laying, the cable-laying machine enables cables to be buried precisely in the seabed according to the designed route, thereby helping to mitigate potential risks such as those posed by fishing boats, marine life, and changes in seabed topography. This helps to extend the lifespan of cables. Cable laying requires extremely high precision; even small angular deviations at the point where the cable enters the machine’s horn-shaped aperture can cause damage such as bending or twisting of the cable. Previously, pressure sensors were commonly used in this industry, but due to factors such as the dark underwater environment and complex operating conditions, their failure rate was high in extreme situations, making it difficult to detect subtle angular changes. This became a bottleneck limiting the precision of cable laying. CNOOC Engineering worked together with manufacturers of cable-laying machines to install high-precision angle sensors at key locations, enabling precise monitoring at 0.01-degree accuracy. Together with a real-time data transmission system, operators can monitor the status of the cables in real time from the control room, achieving “visualization of underwater conditions” and “immediate data feedback.” This solves the problems of inaccurate angle monitoring and delayed feedback in underwater operations. The successful use of this angle detection device provides valuable insights for future cable-laying projects, helping to accelerate the optimization and improvement of similar equipment. It also promotes the transition from experience-based operations to precise, intelligent control in cable-laying processes, injecting strong momentum into the development of intelligent equipment for China’s offshore engineering sector
