Technical field

This application relates to the technical field of ship and marine engineering helicopter platforms, and in particular to a helicopter platform profile structure and its platform fire protection system.

Background technique

For ships operating on offshore platforms or operations, helicopters are the only fast means of transportation. As a facility for helicopters to take off and land, it is usually called a helicopter deck or helicopter platform (hereinafter collectively referred to as a helicopter platform). It is a transportation station that must be equipped for various offshore platforms and ships. It is also an important location for external commuting and emergency evacuation of various offshore platforms and ships. and necessary routes for supplies.

According to the requirements of the International Civil Aviation Organization (ICAO), helicopter platforms, whether on land or on ships, need to be equipped with a fire protection system. The traditional fire protection system includes two or more fixed fire monitors, but the coverage of the fire monitors is greatly affected by the wind. , and ICAO recommends the use of foam as a fire-fighting medium, but the foam liquid itself contains chemicals, which will cause environmental pollution, and after the validity period of the foam, it can only be scrapped and replaced with new foam.

Ordinary helicopter platforms are made of steel. When a helicopter lands and an oil leak occurs, the oil will flow on the surface of the helicopter platform and cannot be discharged to the water system in time, which can easily lead to fires. Even with a fire protection system, it can easily cause heavy losses.
