ExxonMobil Aurora EOS Warehouse
US oil giant ExxonMobil is one of Singapore’s largest foreign manufacturing investors with more than S$20 billion in fixed asset investments. Its Singapore affiliate ExxonMobil Asia Pacific has manufacturing facilities including refinery operations and a petrochemical plant on Jurong Island.
Aurora EOS Warehouse is a 2-Storey Warehouse structures within Singapore Butyl and Adhesion (SBA) project completed in Year 2017. Fire loads in warehouses are increasing and changing on a daily basis as stock movements increase to support business operation, all of which has a significant financial and economic value, often in several millions of dollars. Conventional detection technologies like Spot type Smoke detectors will have difficulty in detecting the smoke as the smoke is heavily diluted due to the high ceiling extending upto 12 meters. They are also considered unsuitable if deployed at such heights.
16 Nos of VESDA-E VEU detectors have been designed, supplied, tested and commissioned by our team for this project, integrating it with the Warehouse Smoke Control System. VEU offers linear pipe lengths up to 400 m and branched pipe networks up to 600m in this project. Longer pipe runs extend detector coverage, reducing the number of detectors required to protect a single fire zone in the warehouse facility. Installing fewer detectors results in reduced power requirements (PSU and batteries), I/O modules, and less cabling and labour. Therefore, a reduced installation cost resulting in tangible and significant cost savings of up to 40% in comparison to other ASD products.
As the detectors were mounted at accessible height, need of access to the ceiling for service and maintenance will no longer be required. This arrangement has completely eliminated the risk for working at height which in terms go in line with the Workplace Safety and Health (Risk Management) Regulations. Maintenance cost are also greatly reduced since eliminating the cost of hiring access equipment (i.e. scissor lifts or boom lift) and additional labour that would otherwise be required if maintenance were conducted at ceiling height.
During the initial design stage, we have also identified that some levels of airborne dust particles may be present in this warehouse environment. VEU’s robust dust rejection minimizes nuisance alarms in comparison to other ASD’s has thus been chosen to be the ideal solution. To improve the performance of the VEU in terms of extending the detector longevity and reducing maintenance frequency, an In-Line filter was being installed in line with every sampling pipe inlet to the detector.
