Digital transformation is reshaping shipbuilding and marine engineering, creating new opportunities to improve design efficiency, information management, and lifecycle integration. Emerging technologies such as digital twins, data-centric models, immersive visualisation, and intelligent human-machine interfaces are redefining how vessels are designed, constructed, and operated, supporting more connected, responsive, and efficient maritime processes.

Structural reliability is a fundamental consideration in the long-term safety and performance of marine structures, particularly as corrosion progressively reduces load-carrying capacity throughout a vessel’s service life. Increasing emphasis on reliability-based design and assessment methods is improving understanding of the combined effects of material degradation, uncertainties, and inspection practices, supporting more informed maintenance strategies and enhanced structural integrity management.

Safe and effective anchoring remains a fundamental aspect of small-vessel operation, with anchor cable loads strongly influenced by environmental conditions and anchoring configuration. Improved understanding of the relationship between scope ratio, water depth, and wind loading is supporting more informed anchoring practices, helping vessel operators optimise holding performance, reduce anchor loads, and enhance safety during stationary operations.

Offshore construction vessels play a critical role in modern subsea field development, bridging the gap between offshore installations and the infrastructure required to construct, maintain, and operate them. As offshore operations move into deeper waters and become increasingly complex, vessel designers are adopting integrated, multipurpose solutions that combine pipelay, diving support, construction, and dynamic positioning capabilities. Growing emphasis on operational flexibility, equipment standardisation, survivability, and lifecycle efficiency is driving the development of advanced offshore construction vessel families that can meet diverse project requirements while delivering improved performance, reliability, and economic value.

Advances in computational fluid dynamics are transforming the prediction of ship performance, offering the potential to reduce reliance on traditional scale-model extrapolation methods and improve understanding of full-scale resistance. Continued research into scale effects, correlation allowances, and surface roughness representation is enhancing confidence in CFD-based performance assessment, supporting more accurate and reliable prediction of vessel efficiency during design and operation.

Preliminary ship design is increasingly recognised as a collaborative and iterative process that extends beyond traditional numerical synthesis to include architectural configuration, operational effectiveness, affordability, and stakeholder engagement. Growing adoption of Design Building Block approaches is enabling designers to explore complex ship arrangements more effectively, supporting requirements elucidation, improving communication between designers and customers, and providing a stronger foundation for evaluating innovative vessel concepts during the earliest design stages.

Understanding how ship motions affect human performance at sea is becoming increasingly important as vessel operators seek to improve safety, productivity, and crew wellbeing in challenging environments. Advances in motion-induced interruption modelling are providing greater insight into the relationship between vessel motions, task execution, and operator stability, supporting the development of more realistic seakeeping assessment criteria and enhancing the design of ships and working environments to reduce operational risk.

The design of modern warships is increasingly shaped by systems engineering principles as naval programmes become more complex, technology-driven, and focused on whole-life capability. Growing integration of multidisciplinary design methods, digital technologies, and lifecycle thinking is enabling designers to balance operational performance, cost, risk, and adaptability, supporting more effective naval ship acquisition and the development of increasingly sophisticated naval platforms.

Advances in podded propulsion technology are driving continued efforts to improve manoeuvrability and propulsive efficiency across a wide range of vessel types. Growing understanding of the influence of hub geometry on hydrodynamic performance is supporting the refinement of podded propulsor designs, with particular attention being given to performance under off-design and manoeuvring conditions where flow interactions become increasingly significant.

Understanding the seakeeping performance of high-speed rigid inflatable boats is essential for ensuring safe and effective operation in demanding sea conditions, where excessive motions and slamming can affect both crew performance and vessel integrity. Experimental investigations into the influence of wave conditions, operating speed, and tube pressure are improving understanding of motion responses, while the development of alternative motion severity measures is supporting more realistic assessment of ride quality and operational limits
