... will be located much farther away from the shore, which is expected to pose major problems in Operation and Maintenance (O&M). So far, research focused on the maintenance strategies for large offshore wind farms shows that the use of an Offshore Mothership is a promising option for minimizing O&M...

... The effects on Required Freight Rate (RFR) of hull roughness causing loss of speed at constant power are investigated. Vessel lifetime roughness profiles are postulated based on construction, coatings, operation and maintenance. These are utilized to determine the loss of speed. The results...

... Unexpected failures can have drastic consequences for ships, and taking a cue from other industries, operators are looking to implement predictive maintenance solutions using sensor data generated by shipboard machinery. One ship operator engaged with artificial intelligence (AI) company Spark...

... Stern tube seals are a critical component in a ships propulsion system, sealing the shafts penetration through the hull. Stern tube seals can result in a significant maintenance burden when they are unable to handle the operational conditions of the vessel. Current systems are also lacking...
