Ship Project & Ship Design (6 credits)

Prof. A. HAGE,

Code = EMSHIP S1-3 (Semester S1)

Workload: Lectures (30h), projects (60h)

Number of credits: 6



The objective is to perform a complete project of a ship (including the general arrangement, scantling, stability, drawings, etc.). The lecture covers the following aspects:

  • Ship design methodology & project.
  • CAD & CAM tools – project oriented.
  • Maritime regulations & classifications societies – project oriented.




    • Set up of project: Mission of naval architecture, principal steps of the project, program of ship «Loop of ship», definition of the main dimension (lengths, surfaces, volumes). Displacement and weight estimation. General characteristics: coefficients in function of the speed, geometric characteristic of hull, adjustment of dimensions for good behavior in sea and stability, control of stability and of trim. Propulsive power: practical rules of dimensioning, special propulsions and their utilizations. Energy on board: Balance sheet of electric and organization of distribution of energy. Protection against corrosion. Consistency of the project and final control.

    • Multihull hull: Planning catamaran, catamaran with foil, SWATH, SLICE, with Outriggers. Comparison - advantages and disadvantages: resistance, seakeeping, performances in sea, behaviors of route, maneuverability, control of positioning, structural resistance. Recommendations for concept and design of multihull.

    • Explosion: Impact of shock and grounding on design of ship. Dimensioning following empirical formulations.


    • Use of CAD (2D, 3D) and CAE tools in ship design.
    • Software for ship design (Maxsurf, Lunais, Napa, Argos, Rhinoceros): 3D hull modeling by using NURB Surfaces (fast and intuitive modeling of the hull shape by means of control points), general arrangement, tank capacities, weight estimation, stability, external aspect, internal structure.
    • Numerical Simulations and calculations:
      • CFD & Ship resistance: Fluent, Fine Marine
      • Structural analysis (FEM: SAMCEF, LSDYNA&USA; MARS): linear static analysis, non-linear analysis, Simulation of grounding and collisions, Underwater and air explosions.Virtual Reality: Virtual Enterprise & Exchange of technical data.


    • Rules approach (classifications societies): BV, ABS, Lloyds, Applications using classification society rules. International regulations: IMO, IACS, SOLAS.
    • Classification, surveillance and inspection for maritime and inland ships.
    • Environment: Protection against pollution «MARPOL».
    • Risk assessment: pollution by hydrocarbons, impact on ship design.

This lecture is an introduction (design oriented) to Ship Design. Applications and exercises to small craft are given in the ULiège-ANAST Lectures (see here after “Design of Small Crafts and High Speed“).

More advanced and complementary lectures in Sailing Boat, Pleasure Yacht are available by selecting Genoa University - Polo Universitario di La Spezia - for the third semester (see lecture contents here after).


Form of exam:

Oral – discussion about student project (30 min).
