Study of the ventilation system for transoceanic transports of live animals

A Dutch shipowner asked us to verify and possibly correct the initial design of the ventilation system of a ship with eight decks, compared to the requirements expressed in terms of air outlet speed, desired temperature in the rooms, number of spare parts air schedules.

The relevant regulations are those established by the Australian Maritime Safety Authority (AMSA).

Furthermore, a comparison of the vertical distribution system with respect to the horizontal one to determine which design required the lowest power ensuring the best flow.

Particular attention was paid to the pressure drop, to the point of operation of the fans and to the uniform distribution of the air flow.

Given the constraints on the positioning of the supply and air outlet ducts, we have created a parametric CFX model with respect to the diameter of the pipes, so that they can be changed without having to rebuild the model every time.
