Damage stability remains a defining challenge for ro-ro vessel safety, where flooding of large vehicle decks can rapidly compromise survivability. Comparative assessment of subdivision arrangements identifies the configurations most effective at improving stability, while introducing a critical deck-height concept that highlights how seemingly subtle design choices can have decisive consequences during flooding events.

AutoPlan is advancing safer, more efficient planing craft operations through integrated design optimization, simulation, and intelligent navigation assistance. Combining hydrodynamic modelling, manoeuvring prediction, instability detection, experimental validation, and full-scale trials, the project aims to reduce fuel consumption, improve safety, and enhance real-time operational decision-making at sea for future maritime applications.

Efforts to standardise shock-mitigating seat assessment for high-speed boats have revealed significant debate over testing methodologies. This analysis clarifies the objectives of emerging standards and addresses common objections regarding waveforms, human response, signal processing, test rigs, and seat designs. The findings support more consistent safety evaluation globally going forward today.

New research is quantifying how coxswain behaviour influences whole-body vibration exposure aboard high-speed craft. Using advanced simulator trials, analysts found throttle control plays a greater role than steering in reducing shock loads. The findings support better training, mission planning, and future autonomous control systems aimed at improving crew safety overall.

Human performance is often the decisive factor that determines whether a minor incident becomes a major maritime disaster. By modelling crews as active safety barriers within a vessel’s defence system, an innovative reliability-based approach provides new insight into emergency response effectiveness, supporting improved accident analysis, risk evaluation, and crew training strategies.

As high-speed vessels increasingly rely on gas turbine propulsion, maintaining reliability while controlling lifecycle costs is becoming a critical operational challenge. A multi-parameter diagnostic approach combining vibration analysis, thermography, tribology, borescopy, and emissions monitoring offers a pathway to predictive maintenance, enabling earlier fault detection, improved asset availability, and more cost-effective maintenance strategies.

As maritime safety frameworks evolve, designers are increasingly turning to data-driven risk assessment to understand the consequences of rare but high-impact collision events. By combining probabilistic scenario modelling with advanced finite-element simulation, a quantitative approach to tanker collision risk enables more realistic evaluation of structural damage, environmental exposure, and economic losses, supporting risk-informed ship design and safety decision-making.

Reference designs are emerging as powerful tools for managing submarine procurement complexity. Running alongside acquisition programmes, they help balance requirements, assess trade-offs, and contain the risks of costly design changes. By supporting informed customer decisions and affordable capability development, the approach improves programme stability, confidence, and long-term outcomes, overall success.

Submarine concept design demands early decisions within a tightly constrained solution space. Examining around twenty interdependent design choices, this analysis highlights how submarine synthesis differs from surface ship development, requiring greater precision, balance, and systems integration from the outset. The findings underscore the sophistication of modern underwater vehicle architecture today.

Process automation is transforming submarine pressure-hull design. By integrating optimisation software, finite-element analysis, and automated engineering workflows, designers rapidly evaluated weight, operating-depth, and collapse-strength trade-offs. The approach uncovered improvements unlikely through manual methods alone, while highlighting the growing importance of expert interpretation in data-rich design environments for future submarine programmes.

Brazil’s first domestically developed submarine simulator marks a significant step in national maritime engineering capability. Built within the University of São Paulo’s Numerical Offshore Tank, the platform combines vessel manoeuvring theory and advanced numerical modelling to support submarine analysis, training, research, and future technology development independently and at national scale.

Accurately predicting submarine behaviour during turning manoeuvres remains a critical design challenge. Comparing coefficient-based modelling, computational fluid dynamics, and free-running tests, researchers found CFD closely matched measured control-surface demands while simpler methods overpredicted requirements. The findings improve understanding of out-of-plane loads and support more effective submarine control-system design today globally.
