... 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...

... 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...

... 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...

... The monitoring of machinery condition, performance, and maintenance activities continues to be vital to the effective management of marine assets. Identifying key data, developing a data collection protocol, and analyzing the data are key to effective management. Planning for these activities...

... conditions, which in turn limits the vessels capabilities to access the wind farms. Additionally, with the constant rise of power utilization, improvements in the Operation Maintenance (O&M) planning are crucial for the development of large isolated offshore wind farms. Improvements in the planning...

... In July 2011, the National Shipbuilding Research Program (NSRP)awarded the project entitled “Reduction of Total Ownership Costs Through Application of Design For Maintenance (DFM) and Repair Methodologies Project” a collaborative shipyard-led research project, supported by Bollinger Shipyards...

.... They are subject to corrosion; and due to the enclosed environment and complex structure, maintenance is very difficult and costly. This paper gives the results of an “insitu” study of ballast tanks on board of more than 150 merchant ships. No selection criteria were applied from the start and the ships were...

... This paper provides insight into the electrical safety by design, installation, and maintenance considerations, specifically as it relates to electrical systems and equipment and the potential consequences if not performed properly. It provides valuable information for the electricians...

... LEDs during the construction of ships allows for a greater TOC savings from increased energy efficacy, lower maintenance costs and a simpler electrical design schematic. There are three options available to incorporate LEDs on a ship: LED lamps, LED fixtures or a combination of the two...
