Mentor gives out tough assignments to sharpen skills of next generation RELIABILITY On any given day, Senior Principal Engineer and Technical Expert Chua Khim Mong, would pose a hypothetical engineering problem in a group chat, challenging his team of technical officers and technicians to solve it. With nearly four decades of experience under his belt, Khim Mong believes tough assignments can help his mentees stretch their capabilities and grow in their careers. Senior Principal Engineer Chua Khim Mong (right) and Senior Engineer Chung Der Chyuan are amongst the 23 Technical Experts appointed to deepen SP’s engineering expertise. “I tell them to never be afraid of asking seemingly silly questions. The most valuable lessons are learned from questioning and probing,” shared Mr Chua. Read the full story on how mentors like Kim Mong are key in helping the next generation of engineers hone relevant skills and expertise on The Straits Times.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Young Animators Draw up Gas Safety Tips RELIABILITY Working closely with NYP students were SP Group’s gas safety committee and corporate affairs department. The team comprised (first row, from left) SP’s Engineer Lydia Koh, SP’s Senior Engineer Nur Hafiza binte Mohd Zulkifli, NYP’s Lim Shu Ming, NYP’s Koh Chiau Wen, SP’s Head of Corporate Affairs, Amelia Champion, NYP’s Andrea Low, (second row, from left) NYP’s Quek Yu Jie, SP’s Senior Engineer Lo Ai Jin, NYP’s project supervisor Bhakta Srini, SP’s Senior Engineer Roseanne Chan, and SP’s Deputy Director, Corporate Affairs, Jeanie Lee. When Nanyang Polytechnic student Quek Yu Jie was 10, he came home to a strange smell and a hissing sound. He witnessed his mother’s quick reaction: she turned off a gas ring that had been left on, and opened all windows in the flat. “My mother knew we needed to let the gas out quickly. But I don’t think we knew we had to shut the main gas valve and leave all other appliances untouched,” Yu Jie, now 25 and a Nanyang Polytechnic final year student, recalled. Yu Jie and three other animation coursemates from NYP’s School of Interactive & Digital Media learnt this when they created a series of gas safety videos for SP Group as part of their Final Year Project. The biggest learning for them was that, using a mobile phone during a gas leak can spark a fire due to the microwaves emitted from phones, said Yu Jie, who led the video’s post-production. Statistics have shown that 42.5 per cent of the gas leaks attended to in the second half of 2018 were due to the misuse of gas appliances.  The videos are part of a gas safety campaign that is rolled out in September this year. NYP students engaged with the SP team to come up with a compelling public education campaign The team used animation to highlight key safety tips: how to detect a leak, ways to prevent gas-related incidents, and the importance of engaging a Licensed Gas Service Worker to install gas appliances. Team-mates Koh Chiau Wen and Lim Shu Ming, both 19, took the lead in developing key characters, while Andrea Low, 20, focused on creating the backdrop. The students worked closely with SP to decide on the best ways to drive home the key messages to a broad audience. “We want to raise the level of gas safety awareness as many people overlook the correct and safe use of gas appliances and accessories,” said Nur Hafiza binte Mohd Zulkifli, Senior Engineer, Gas Operations, from SP’s gas safety committee, a workgroup on gas safety education. Final Year Projects usually take about 480 hours, but project supervisor Bhakta Srini said that for this one, each put in up to 30 hours more, including over weekends and after school, to perfect the videos and capture the realism of human characters. “One second of a film is 24 frames and requires 12 drawings.  We created over 1,500 drawings in total,” explained Chiau Wen, who led the project team. But the students all agreed that it was worth it, since the videos get the message across using everyday scenarios. NYP students had to acquire gas safety knowledge from the SP Engineers and figure out how best to communicate this. Head of Corporate Affairs, Amelia Champion said the collaboration with the polytechnic helped to bring across SP’s gas safety advice through the lens of the students. “Anyone can potentially help detect or prevent a leak or be an advocate for safe practices. This series aims to make our safety messages easily understood and shared with others.” — 24 September 2019 TAGS RELIABILITYGAS SAFETY YOU MIGHT BE INTERESTED TO READ Ground feedback, digital tools: How she helps 8,000 workers end their day safely Faster repairs, fewer disruptions: Meet the innovative teams using smart tech to keep your piped gas supply flowing Engineer, 27, shares how she is undaunted by male-dominated energy industry & climbs the ranks

Taking Heart Big boost to funds for the elderly THE Singapore Power Heartware Fund – which supports more than 31,000 beneficiaries under Community Chest’s 26 programmes for the elderly – received a S$600,000 boost on Friday, through Singapore Power’s annual charity golf event. The figure represents the largest amount ever raised in the event’s 10-year history. The fund helps to provide services such as dementia day care, hospice care, community homes and caregiver support to the elderly. As part of the Care & Share Movement that Community Chest is leading this year, the funds will also be matched dollar-for-dollar by the government. The matched amount will go towards building the capabilities of the social service sector.
