SINGAPORE TECHNOLOGIES ENGINEERING LTD Annual Report 201139Hangar Capacity ExtensionHangars are an integral infrastructureinvestment for the maintenance, repairand overhaul (MRO) business of theAerospace sector. Through out-of-theboxthinking, a team comprising staffwith diverse professional backgroundcame up with a cost effective idea toincrease hangar capacity for widebodyaircraft without the need forland acquisitions and other capitalinvestments. The use of a lightweight, semi-transparent, moveablestructure gives us the flexibility to makeslots available to service aircraft ofdifferent sizes while maintaining ourhigh standards in safety and aircraftprotection.FBG sensor used in AgilFence PIDS.The proprietary AgilFence PIDSwith intelligent signal processingwas developed by ST Electronicsbased on fibre sensor technologylicensed from its research partner,the A*STAR Institute for InfocommResearch. The AgilFence PIDS wascustomised to meet the uniqueoperational requirements of<strong>Singapore</strong> Changi Airport.specific areas to be customised toachieve a higher probability of detectionwhile reducing the possibility of falsealarms triggered by weather elementsand wildlife along the perimeter.Modular HoverbargeThe 50-tonne modular Hoverbargewas developed by ST Marine incollaboration with its subsidiary,Hovertrans Solutions. When off hover,the Hoverbarge floats on water like astandard marine barge. When hovering,it is able to traverse swamps, mud,shallow water and rivers in remoteareas where heavy lift is required. Ithas a large deck area for payloadand is scalable up to over 2,000tonnes. Applications include cargotransportation, oil exploration & drillingand ice breaking.Hangar capacity extension.Fibre Sensor Technology forPerimeter Fence SecurityIn August, the Changi Airport Groupand ST Electronics’ wholly ownedsubsidiary, ST Electronics (Satcom& Sensor Systems), announced acollaboration to implement a PerimeterIntrusion Detection System (PIDS) tostrengthen airfield security at <strong>Singapore</strong>Changi Airport. This is the first timethat Fibre Bragg Grating (FBG) sensortechnology is being used for perimetersecurity enhancement anywhere inthe world.Unlike non fibre sensor technologies,the performance of the AgilFencePIDS is not affected by factors such aselectromagnetic and radio frequencyinterference. Also, the high pinpointingaccuracy of the AgilFence PIDS allowsoptimal deployment of closed circuittelevisions around the perimeter fence.The unique signal processing algorithmof the system allows FBG sensors at50-tonne modular Hoverbarge can be split into separate units.The uniqueness of the 50-tonneHoverbarge is its modular designconsisting of ISO-container sizeindividual watertight modules, peripheraldetachable skirt frames and lift fansystem. The modular design enablesthe Hoverbarge to be split into separateunits and trucked to a location where itcan then be assembled on-site.
