The objectives of shipboard fire prevention are essentially to reduce risks to life, cargo, preventing the development of fires and explosions, providing means for fire control and suppression, and also safe escape routes for people on board.

The passive protection plan includes the activity of compartmentalizing the hull and superstructure with bulkheads and decks with specific fire resistance requirements. Insulation solutions intended to impart fire resistance performance to decks and bulkheads are subjected to fire tests capable of evaluating their effectiveness according to the required parameters.

The current regulations first set out the main objectives of the fire protection system by stating that "the purpose is to require the most complete degree of fire protection," and provides a number of definitions necessary for the treatment of the subject. These include the following:

Noncombustible material - is a material that does not burn and does not produce flammable vapors in sufficient quantity for self-ignition to occur when heated to a temperature of at least 750 °C. Any other material is considered combustible for regulatory purposes.

IMO, the International Maritime Organization, is the United Nations specialized agency for naval safety.

 "B-0" 0 min isolation 30 min integrity

"B-15" 15 min isolation 30 min integrity

"A-0" 0 min isolation 60 min integrity

"A-15" 15 min isolation 60 min integrity

"A-30" 30 min isolation 60 min integrity

"A-60" 60 min isolation 60 min integrity.

Class A divisions are those divisions formed by bulkheads and bridges that meet the following criteria:

(a) are made of steel or other equivalent material;

(b) are properly stiffened;

(c) are insulated with approved non-combustible materials in such a way that the average temperature of the unexposed side will not increase by more than 140° C above the original temperature, nor the temperature, at any point, including any joint.

- class "A-60" 60 min

- class "A-30" 30 min

- class "A-15" 15 min

- class "A-0" 0 min

Class A divisions must be constructed to be able to prevent the passage of smoke and flames until the end of the standard one-hour fire test.

Our proposal for Class A passive deck compartmentation features a revolutionary low-thickness package, occupying only 36 mm of footprint.

This innovative package consists of the Nobilium Thermalpanel thermal insulation panel, made of noble basalt-grafted rock fiber, accompanied by a self-levelling, single-component, fiber-reinforced cement mortar suitable for interior ship decks. This combination offers high fire resistance, providing a solid barrier against the spread of smoke and flames.

The implications of this solution are revolutionary for shipowners and shipbuilders. Reducing weights on board ships not only improves cargo capacities, but also allows for increased heights on board, facilitating the passage of equipment.

This optimization results in a safer environment due to the high flame resistance of Nobilium Thermalpanel.
