Investigating the winch performance in an ASV/ROV autonomous inspection system

Combined Autonomous Surface Vehicles (ASV) and remotely operated underwater vehicles (ROV) inspection intervention systems can contribute to future asset management of offshore renewable energy. This paper presents the design performance winch system which couples ASV ROV deploys/recovers ROV. The hydrodynamic models control algorithms are developed solved with analytical numerical approaches. needs meet a range operational profiles, including i) following/not following ii) operating in speed iii) tension iv) varying distance depths targets. For representative ASV/ROV configuration, work determines required umbilical length for different targets suitable speeds. results show that strategy where follows reduce tension, but conditions compression should be carefully managed. also decreased by shows very effective larger sea states. study accidental limit case, malfunctioning is recovered. estimated increase during recovery stage thus incorporated into calculations.
