Safety
other is defined and engineered to ensure compliance with required standards and regulations, whilst providing the equipment required to enable connectivity and visibility. Te software is programmed using the software tools provided by the equipment manufacturers, but the application software will be developed by Blaze and will be unique to the site. Depending on the specific client
requirements for detection, the company can provide standard EN54-compliant approved fire panels or enhanced SIL2 certified fire alarm panels, approved for offshore and onshore environments. Te fire alarm equipment used will be predominantly addressable and employ analogue or digital addressable technology. As part of ensuring compliance with EN54, it is important that the most suitable uninterrupted power supply (UPS) is sized for the project. Te company’s engineers will size the most appropriate batteries and UPS based on the required Amp/hr rating. Te firm also uses an intelligent UPS system that allows key monitoring parameters to be passed to the programmable logic controller (PLC) via ethernet protocols. Tis allows key information to be distributed amongst local and third-party or operator interfaces in addition to the information being available for visibility remotely.
For the protection systems, clean agent
gas suppression systems or foam water mist systems are usually specified. Tese systems can be operated and controlled by using local extinguishing control panels or can be tied back to a centrally located PLC, programmed to perform logic based on a project specific cause and effect document and in accordance with national or international standards. In both cases the architecture will be configured so that the extinguishing systems communicate with the addressable fire alarm system to make their status visible remotely. Te fire alarm panels are capable of operating on their own as single stand- alone units or can operate as networked units as may be necessary in the case of larger sites. Te panels will be programmed using the manufacturer’s software to create the application for the client site, using cause and effect diagrams that can be supplied by the client or by Blaze. To provide a step towards the system being connected, the company uses the Commander – a powerful internet protocol (IP) based controller that provides protocol translation, enabling the addressable fire alarm panel to be integrated to a powerful PLC. Te Commander is used as a simple bridge between the addressable panel and the PLC allowing conversion from one
OFFSHORE WIND CASE STUDY B
laze is currently using this smart safety technology on one of the offshore platforms
associated with Orsted’s Hornsea One project. The giant Hornsea One offshore windfarm, which will be the biggest in the world, will be located off the Yorkshire coast and will meet the electricity needs of over one million UK homes. The project is due to complete in 2020, installing 6.5GW of offshore wind power. Blaze is providing the detailed
design, manufacturing and installation of the fire extinguishing and addressable fire alarm systems that will be in place on

Construction of the Hornsea One project for Orsted
the Hornsea One unmanned offshore Reactive Compensation Substation. The systems will be integrated
together to provide an automatic fire detection and alarm system. When a fire is detected by sensors installed on the addressable fire alarm system loops, signals are
routed to the extinguishing control panels in the affected area or room and the extinguishing systems are activated automatically in the area. The extinguishing agents that are being used include gaseous fire suppression systems provided by Blaze. l
