Safety Challenges and Risks due to Alarms in DP Vessels. Emphasis on Impact of New Energy Solutions. Applicable to Oil and Gas, Offshore Wind and Aquaculture.
Master in Maritime Operations, Offshore and Subsea Operations, Haugesund, Norway Compared to regular sea-going vessels, DP vessels operate in an area with a high risk of accidents. This research investigates some of the main risks and challenges of DP vessels. Thus, the purpose is to investigate the...
