SUMMARY:Site visit: fire suppression condition monitoring at AirportLink
DESCRIPTION:Overview\nRoad tunnels have design lives of 50-100 years\, with Mechanical\, Electrical and Fire assets having design lives of only 5-25 years. Managing deterioration that triggers changes in condition and performance is essential to enable the fire safety strategy defined in the Fire Engineering Report\, as well as to identify need for amending it as both technology\, technical and legal requirements change. This presentation will present a project in which the condition of the combined fire mains in an established road tunnel (AirportLink) was assessed through non-destructive techniques (NDT) to inform the asset manager of the expected service life remaining\, which in turn informs both short- and long-term investment. The presentation will be followed by a visit to the tunnel during a maintenance closure to discuss some of the drivers and challenges of the project arising from the available maintenance windows and the physical layout of the system. \nThis site visit is targeted primarily towards young engineers\, however we do welcome all engineers. \nProgram timeline\n6.30pm – Registration\, safety check and brief introduction. \n7.30pm – Fire mains condition assessment presentation \n9.00pm – Maintenance toolbox \n10:30pm – Tunnel closes for access \n10:45pm – Group tunnel walk \n12:30am – Group exits tunnel and wrap up \n1:00am – Site visit concludes \nThis site visit concludes after midnight and the timetable may be subject to change depending on traffic conditions. \nMinimum PPE requirements\nAttendees are required to have full PPE for participation\, including: \n\nLong Trousers – 2 Reflective Stripes\nLong Sleeve Shirt – Reflective Stripes\nClear Safety Glasses\nHard Hat (in Date)\nGloves\nLaced Up Steel Capped Boots (Secured & Fitted)\nHearing Protection\n\nAttendees that do not comply with the minimum PPE requirement will not be admitted on the day. \nPlease Note: Mandatory alcohol testing and random drug testing will be conducted upon arrival.  \nAbout the speaker\n\n\n\nJaime Cadena Gomez\nPrincipal Engineer\, Fire Safety\n\nJaime Cadena Gomez is an engineering professional with 17 years of experience understanding and managing operational risks and performance of critical infrastructure. Currently\, he is the Principal Asset Engineer for Fire Safety across a network of 16 road tunnels in Australia.

SUMMARY:Choosing the right VSD for tunnel ventilation application
DESCRIPTION:Overview\nIn recent years\, several tunnel projects have faced serious setbacks due to catastrophic motor failures. These failures are caused by high peak voltages\, a result of using Active Front End (AFE) VSDs combined with long motor cable lengths\, extending to 500 meters. This session examines the underlying electrical phenomena contributing to these issues and why conventional mitigation methods\, such as standard filters\, are often insufficient. \nParticipants will gain practical insight into proven engineering solutions that deliver near-sinusoidal voltage at the motor terminals\, reducing stress on insulation and extending asset life. Drawing on real-world case studies and field testing\, the session highlights key design considerations\, specification pitfalls\, and lessons learned to support more reliable tunnel ventilation system performance. \nLearning outcomes\nIn this event\, attendees will be able to: \n\nidentify the root causes of high peak voltages in AFE VSD tunnel applications\nevaluate why conventional filtering methods may not adequately protect motors apply practical design and specification strategies to prevent premature motor failure\nselect VSD and mitigation solutions that improve reliability and extend asset life\n\nProgram\nIn-person: \n\n5.00 pm AEST: Guest arrivals and registrations\n5.30 pm AEST: Presentation begins\n6.15 pm AEST: Q/A begins\n6.30 pm AEST: Event close\n\nOnline: \n\n5.30 pm AEST: Presentation begins\n6.30 pm AEST: Presentation ends\n\nAbout the speakers\n\n\n\nJoris Feekman\nRegional Sales Manager\, Danfoss Drives\n\nJoris is Regional Sales Manager at Danfoss Drives\, with over 25 years of experience in electrical drives and industrial power conversion. He has experience across Europe and Australia\, delivering reliable motor control solutions across a wide range of industrial applications.\n\n\n\n\n\n\n\n\nHusain Natalwala\nBusiness Development Manager\, Danfoss Drives\nHusain has strong experience supporting large-scale industrial and infrastructure projects\, with exposure to Industrial Automation and Electrical Systems. At Danfoss\, he works as a BDM focussing on Tunnel Ventilation\, Water and Food Industries.
