Robert Allan Ltd. has in recent years designed a significant number of emergency response vessels for major port cities around the world. Primarily configured as fireboats, these platforms also frequently serve as Command and Control centres or indeed as primary response vessels for local emergency actions, such as pollution response and search and rescue. These vessels have a diverse array of configurations and fire-fighting performance.
