The Dynamic Positioning Error Force Modelling system, for instance, is coupled with two bow thrusters to enable the crew to fight fires at any angles while maintaining the vessel’s position. The result was a highly versatile vessel designed to operate in different firefighting modes under a wide range of operational scenarios. During the design stage, we were constantly asking ourselves whether there were any improvements that could enhance the vessel further. The HFV is the world’s first Fi-Fi III Chemical, Biological and Radiation (CBR) firefighting vessel only because our goal was to build a robust vessel that can deliver the best performance to fight fires and to save lives at sea. He said, “If you are going to build something that is going to be the world’s first, you cannot afford to play safe and be conventional. Yeow Xian Ching, a member of the HFV project team, believed that it was the forward-looking attitude and design-thinking mindset of the SCDF, Defence Science and Technology Agency and ST Engineering Marine that enabled the delivery of the vessel’s ground-breaking firefighting capabilities. “Then, we subject the hull form to a further series of CFD simulations and model tests to determine the optimal shape that can achieve the best speed, fuel efficiency, manoeuvrability and seakeeping performance.” Optimised hull form with less drag means better fuel efficiency and higher speed,” said Daisy. “We used computational fluid dynamics (CFD) to optimise the hull form and the ship appendages, including the stern wedge, duck tail and bow, to reduce water resistance. To achieve its exceptional mission capability, the HFV design team, led by Daisy Dong, Director of Hull at ST Engineering Marine’s Engineering Design Centre (EDC), has incorporated several breakthrough innovations into the vessel’s design from the onset. This formidable vessel is a collective effort by the HFV project team members and built in ST Engineering Marine for the Singapore Civil Defence Force (SCDF) to support SCDF’s firefighting and rescue missions in Singapore Territorial Waters. The 50-metre HFV can deliver an unparalleled 14,400 m³/h. The heavy fire vessel (HFV) that was launched in June 2018 is the world’s first firefighting vessel classified to Fi-Fi III by the American Bureau of Shipping (ABS) for its outstanding firefighting capacity.Īccording to ABS classification, a Fi-Fi III class firefighting vessel must be able to produce a total water capacity of more than 9,600 m³/h, with monitors that can be remotely controlled from the wheelhouse. Daisy Dong and the project team behind the Singapore Civil Defence Force’s new heavy fire vessel reveal the key innovations behind the first firefighting vessel to be designed and built in Singapore.
