Understanding how water spreads through damaged compartments is essential for predicting survivability and improving damage-control strategies in naval vessels. Experimental flooding tests on a generic destroyer model revealed how damage extent, waves, and heel angle influence floodwater distribution and equilibrium levels, providing valuable data for validating flooding simulations and enhancing post-damage safety assessments.

Achieving reliable predictions of stiffened panel strength remains a key challenge in marine structural design, particularly when boundary conditions cannot be defined with complete certainty. This study evaluates a range of stiffener configurations and finite-element modelling approaches to identify more robust panel designs, improving confidence in ultimate-strength assessments and supporting more resilient ship structures.

Accurate prediction of extreme loads is fundamental to structural reliability assessment, yet traditional extreme value methods may not fully account for variations in the likelihood of occurrence. This study proposes an enhanced application of extreme value theory that incorporates exceedance probabilities, reducing uncertainty in predicted extremes and providing a more realistic basis for safety and design evaluations.

Underwater radiated noise from commercial shipping is becoming an increasingly important environmental issue, particularly because of its potential impact on marine species that rely on sound for communication, navigation, and feeding. This review highlights propeller cavitation as the dominant source of ship noise and identifies opportunities to reduce acoustic emissions through improved propeller and wake-field design. The findings suggest that targeting the relatively small number of vessels responsible for the majority of noise pollution could deliver substantial benefits, while emphasising the need for comprehensive full-scale measurements to support effective noise-reduction strategies alongside energy-efficiency improvements.

Offshore transhipment operations are often constrained by vessel motions and weather-related downtime, creating significant challenges for supply chains and port efficiency. This study evaluates an innovative Floating Harbour Transhipper concept and demonstrates that its sheltered well-dock arrangement can substantially reduce feeder-vessel motions compared with conventional side-by-side transfer methods, improving the reliability and operability of open-water transhipment.
