With accommodation for up to 152 personnel, Derwent is a multi-service vessel built for complex subsea operations and work scopes that cross a wide spectrum of duties, including construction support, IRM, and light/medium well intervention.

To meet the subsea industry's stringent standards and classifications for specialised vessels, innovative fire protection systems solutions are needed. The Derwent's fire alarm system is centred on three Kentec Syncro ASM analogue addressable panels in a network integrated to 300 Apollo Discovery Marine addressable smoke and heat detectors, supported by 80 addressable manual call points.

The system is also designed to generate alarms via 60 alarm bells and 20 sounder/beacons and includes EPAS PLC based gas detection/alarm and Co2 fire extinguishing systems designed, engineered, integrated, approved to ABS MODU rules and supplied by Epas Fire Protection Pte Ltd, who are also responsible for its testing and commissioning to ABS rules and owner's compliance.

According to Kentec their Syncro ASM is ideal for marine fire specialists because of the ease with which these 'open protocol' fire control panels can be networked to provide scalable fire alarm systems, suitable for many classes of vessel.
