CFD simulations run by Robert Allan Ltd. confirm the design speed of 20 knots is achievable

The Khulna Shipyard in Bangladesh is building two Robert Allan Ltd. designed fireboats. They are under construction for the Bangladesh Navy, which uses the old-style term “fire floats” to describe them. There is, however, nothing at all old style about these cutting edge 18.9 m x 5.3 m vessels.

Designed for river service, they will feature a special hard chine semi-displacement hull itted with twin open style skegs for debris protection.

The all aluminum hulls will be powered by two 560 kW 6135SFM85 John Deere main engines for a speed of 20 knots. Reduction gears will be Reintjes WAF 244 with 2.5:1 reduction ratio driving stainless steel shafts and bronze propellers. The engines are easily removed from vessel via matching hatches in main deck and overhead in-house top.

Self-propelled CFD simulations run by Robert Allan Ltd. confirm the design speed of 20 knots is achievable.

A single Westerbeke 23.0 EGED generator provides electrical power.

Two 2,000 liter/minute fire pumps will be fitted, each driven by a 55 kW Iveco diesel engine. The pumps are located low in the boat so priming systems are not required. Two 2,000 liter/minute fire monitors are located on the house top within view of the operators in the pilothouse.

Foam concentrate capacity is 500 liters and six hydrants are located fore and aft on the main deck.

Most of the accommodations are on main deck level including an officer’s cabin with attached WC, galley, mess, and seating for 12 fire fighters in an air-conditioned deckhouse. Overnight berths for six persons are located in the forecastle. The joiner work utilizes aluminum honeycomb panelling to reduce weight.
