Stability and hydrodynamic

Identification of critical areas to avoid delays during drawing, approval and construction

The rapidly changing face of maritime regulations mandate that those who are involved in vessel design and construction remain completely up-to-date on the status and progress of regulatory requirements and their impact on new design.

The increasing demands placed on ship design standards, both in terms of safety and operating performance, compels that designers must find technical solutions that go beyond mere compliance with class and statutory rules.


Hydrodynamics. Prediction of wave-induced ship motions and loads, plus eventual feedback into the various aspects of the design process:

  • Hydrodynamic global and local loads for FEM structural direct calculations
  • Ship motion for seasickness analysis
  • Operability for high-speed craft
  • Slamming and sloshing loads.
  • Numerical hydrodynamics can also be used to validate and complement tank tests or sea trials.

Stability & Hull Girder Strength. Stability and Hull Girder Strength calculations with NAPA software can be performed from the very early stages of a feasibility study. This way, different design solutions can be assessed against applicable rule requirements. Assistance can also be provided at later stages of design for the validation of onboard loading instruments and for the preparation of loading sequences for bulk carriers.


RINA experts, working in co-operation with shipyard design teams, can use their technical knowledge and professional expertise to facilitate the conception of efficient and safe ships, which conform in every respect to regulatory requirements, while meeting owners’ expectations in a cost-effective manner without compromising performance.
Also we can advise on additional class notations and how to obtain them, as well as provide facilitated maintenance management during the ship’s life-cycle.
