The City of Chicago recently con- tracted Hike Metal of Wheatley,

Ontario Canada to construct a new heavy-duty NFPA 1925 Type III

Fireboat to replace its 55-year-old fireboat. This new 90-ft boat is designed to break up to 12 inches of first-year ice at three knots and can therefore operate year round on Lake

Michigan and the Chicago River.

It is equipped with Caterpillar marine diesel engines; two 1,000 hp engines driving the main fire pumps for a total delivery capacity of 14,000 gallons per minute of water (and foam if required), at 150 psi to fire monitors and hose hydrants, or the vessel can be used as a pumping sta- tion to supplement the cities firemain supply; and two 1,500 hp propulsion engines, capable of driving the vessel at 12 knots.

The fireboat will be operated by a crew of five during normal operations and a crew of ten while in fire-fight- ing operation mode. The vessel is equipped with special alloy propellers designed and made for the severe ice conditions it will operate in. The fire- boat is heated and air-conditioned. It has a deckhouse designed to contain the pilothouse, a multi-purpose cabin which contains an emergency com- mand center, an emergency medical treatment center, a decontamination station and fire-fighting equipment storage. Below decks there are crew accommodations, a mess area and washroom facilities.
