DESCRIPTION
The Langeled pipeline is a 1,200 km undersea pipeline from the Ormen Lange off cost of Norway to the east coast of the United Kingdom. In order to prepare the sea-floor for the pipeline, Nexans developed the Spider, a remote-controlled underwater excavator designed to prepare the seabed for pipe-laying. The Spider is controlled using newly developed 3D software, sensors on all movable parts of the machine, and a network of acoustic transmitters placed on the ocean floor. The 3D model of the seabed is updated in real time using a National Instruments LabVIEW human-machine interface (HMI) to show terrain changes, and the Spider is controlled using the National Instruments CompactRIO programmable automation controller (PAC) platform.
