Fighting fires from a safe distance, regardless of water levels and weather conditions.
WHEN loading and unloading vessels, there is the risk of leaking fuel or liquid natural gas becoming an ignition source. Adaptation to the surrounding conditions will ensure successful fire protection for jetties and freight ships.
Weather and water level changes must be considered, requiring the fire extinguishing system to be versatile and reliable.
Assets that need to be protected are:
- Flammable liquids, such as fuel and liquid natural gas
- Loading arms and pump manifolds
- Engine rooms and freight goods
Generally, it is distinguished between extinguishing technology that is installed on shore, i.e., for jetty protection, and extinguishing technology that is mounted on freight ships.
On shore: Automatic and pinpointed extinguishing at maximum reach
Firefighting monitors that are installed for the protection of jetties must be extremely sturdy. All FireDos monitors are made of a high-grade seawater-resistant aluminum alloy.
Their water-/media-exposed parts are designed to handle pressures of up to 16 bar and bearings are lubricated for life. In addition, seals with reduced friction resistance require only low operating force, even after long down-times.
Firefighting monitors are normally installed on towers, enabling efficient firefighting even under headwind conditions and protecting them from rising water levels.
FireDos monitors are designed for extinguishing agent flow rates from 500 l/min up to 60 000 l/min. Thanks to the flow-optimised Oval Flat Design, the pressure loss is very low, enabling the monitors to achieve maximum reach. Along with the integration into automated fire extinguishing, this extended reach makes the remote-controlled FireDos monitors fit for pinpointed fire extinguishing from a safe distance.
On-board solutions: Quick firefighting with foam
On-deck monitors are mainly intended to discharge low-expansion foam.
Monitors are normally located along the central line of the deck to fight a fire as fast as possible and to keep it from spreading. Doing so, a 25% dimensioning safety is recommended. The monitor should be dimensioned and positioned in a way to reach a distant target at 75% of its maximum reach and flow rate under windless conditions.
Proportioners for firefighting with foam
Fires in the jetty area may require extinguishing with water or foam. Stationary proportioners are installed in the sprinkler control room to supply the foam for extinguishing.
On freight ships or oil tankers, stationary proportioners for firefighting with foam are used both on deck and inside the vessel. Also there, the units should be placed at a sufficient distance from the risk area.
FireDos proportioners are suitable for all foam agent types, including high-viscosity foam agents. These units are extremely reliable thanks to their purely mechanical product concept.
The eco-friendly testing of the proportioning rate without generating premix or extinguishing foam also enables savings as there are no cleaning costs for disposing of premix or extinguishing foam.
