About the Laboratory

The Ship Safety and Ship Handling Simulator Laboratory supports research and education in ship manoeuvring, marine accident analysis, navigational risk, passenger-vessel safety, and computational approaches to safer marine-system design. The laboratory uses modelling, simulation, numerical analysis, and data-driven methods to investigate how vessels can be designed and operated more safely.

An emerging research direction explores how ship geometry — including superstructure form — can reduce wind-induced aerodynamic loads, heeling moments, and vulnerability to capsizing in severe weather. This research-stage work uses theoretical and computational methods to build design knowledge and screening tools, with future expansion toward higher-fidelity CFD, physical experiments, and industry collaboration.

The laboratory also provides a platform for student design research. International competition results highlight academic design capability, sustained student engagement, and a growing portfolio of computational marine design. These achievements provide a strong foundation for future prototype development, validation studies, and broader professional application.

ANN-Based Hydrodynamic Shape Optimization

A resource-efficient surrogate-model framework for research-stage hydrofoil-section design using numerical data, artificial neural networks, adaptive sampling, and constrained optimization.

Constrained SLSQP search

The study compares one-shot Sobol sampling with optimization-based adaptive sampling under the same final sample budget. The adaptive strategy concentrates new evaluations near predicted optimum regions rather than distributing them uniformly.

  • Objective: maximize foil lift while constraining drag and sectional area.
  • Designed as an economical research-stage screening approach for resource-conscious computational studies.
  • Provides a pathway toward higher-fidelity CFD, cavitation and structural assessment, and experimental studies.
Development pathway: the results establish a computational proof-of-concept for a single baseline foil and fixed flow condition using XFOIL. Future stages can extend the framework through higher-fidelity CFD, cavitation and structural assessment, and experimental studies for craft-level design.
Unifying direction. These projects reflect a broader research interest in safer and smarter ocean-engineering systems: combining engineering physics, simulation, and data-driven tools to explore design spaces more efficiently. AI supports prediction, screening, and optimization, while future physical validation strengthens the pathway toward practical engineering application.

The simulator combines the Google Maps API with Nomoto’s K–T manoeuvring model to visualize and control a ship’s planar motion in real time.

  • Uses three linked JavaScript modules: trajectory, Google Maps, and control codes
  • Solves the Nomoto K–T response using the fourth-order Runge–Kutta method
  • Accepts ship dimensions, speed, initial heading, rudder command, and nondimensional K′ and T′
  • Displays animated position, instantaneous heading, rate of turn, and live response graphs

Collision Avoidance for Autonomous Ships

The collision-avoidance work links algorithmic decision support for autonomous ships with evidence from inland-waterway collision characteristics in Bangladesh.

  • Compares route-planning and collision-avoidance approaches for autonomous navigation
  • Uses simulator-based scenarios to examine encounter handling and decision support
  • The 2010 accident study identifies collision as a major inland-waterway safety problem
  • Cargo vessels were frequently involved, and inadequate lighting, reporting, and collision-avoidance devices were key concerns

The recognition highlights student competence in hydrofoil engineering, computational design, surrogate modelling, and optimization, and marks a strong research-stage achievement with clear potential for further development.

What the research demonstrated

The study parameterized a NACA0012 foil with eight Hicks–Henne design variables, generated numerical lift/drag data with XFOIL, trained an ANN surrogate, and used SLSQP to search for improved foil geometry under drag and area constraints.

173final samples in each comparison
58.68%numerical lift increase with adaptive sampling
1×10⁶Reynolds number used in the study
  • Adaptive sampling placed additional numerical evaluations near predicted optimum regions.
  • The optimized result maintained the study's drag and sectional-area constraints.
  • The framework provides efficient preliminary screening and a focused starting point for higher-fidelity validation.
