Sammendrag
The subsea infrastructure of the OceanLab laboratories is located in the Trondheim Fjord. It includes both new and existing fixed and mobile assets of NTNU’s Applied Underwater Robotics Laboratory, that could be monitored and operated remotely from the land-based control room. The mobile infrastructure consists of support vessel and a fleet of different remotely operated and autonomous vehicles. The fixed infrastructure contains two-cabled (power and fiber-optic) seabed sites, instrumented for monitoring from shore. The Subsea Docking Plate (SDP) is designed for experimentation and testing of homing and docking of medium and small-size AUVs. These are important capabilities to enable persistent and resident vehicles. The SDP also serves as a testing facility to qualify technology for use on offshore oil and gas installations. Plate is equipped with wireless inductive connectors for both power (50W-2kW) and communication (80Mb/s). The Pig Loop Module (PLM) was an offshore unit before it was converted to the application within NTNU. PLM is acquired in collaboration with Equinor to serve as a mock-up subsea installation to experiment with subsea intervention and inspection tasks and it includes a dummy ROV panel with marking. To provide real-time situational awareness and remote presence at the sites, an instrument rig with remote sensing, communication and environmental payload will be installed to observe vehicles and installations. Presentation will focus on applications and the first results from Q1-2021. The infrastructure will be available for collaborating partners from industry and/or academia in 2021, while in its full scale it will be available in 2023.
