Course Description: Understanding the behaviour of subsea cables on the seabed is critical for the safe, robust, and cost-effective design & operation of offshore wind farms, power transmission infrastructure, and global telecommunications networks. In particular, understanding cable On-Bottom Stability (OBS) influences decisions for cable selection, installation planning, and lifetime operation. Prevailing design practice has inherited legacy engineering methods from the offshore oil & gas industry, generally developed to understand the behaviour of subsea pipelines. Whilst a useful basis, these legacy methods do not appropriately capture phenomena that influence cable OBS analysis. Such phenomena include boundary layer effects, breaking wave effects, cable bundle behaviour for HVDC cables, and cable response under high Keulegan-Carpenter (KC) number. Cable-seabed interaction also proves practically important for many of the sites onto which OWF subsea cables are being installed, where mobile seabeds (STABLEpipe method) and rocky seabeds (COREstab method) need to be addressed. Practical tools are available on the market that now consider these cable specific and seabed-related effects. Furthermore, cable behaviour directly impacts interfaces with subsea structures for offshore wind farms, including turbine foundations and offshore substations, where cable OBS behaviour can lead to risks for cable integrity.
