CORPORATE OVERVI EW PERFORMANCE REVI EW SUSTAINABI L ITY CORPORATE GOVERNANCE F INANCIAL REPORT Ensuring the Safety of Autonomous Systems As we develop more autonomous products and systems, we added new analytical tools to enhance our system safety practices. This included the identification of operational scenarios and potential hazards to ensure there will not be unsafe controls or actions during operations. At the same time, we carried out simulations and scenario-based tests to validate our design before carrying out actual critical tests. We also referred to local and international standards for autonomous systems to ensure that we adhere to all current standards and requirements of regulatory bodies including that of the Civil Aviation Authority of Singapore and Singapore’s Land Transport Authority. We have successfully conducted several autonomous systems demonstrations and public trials. We will continue to learn and apply industry best practices and techniques to ensure the safety of our products and solutions. Improving Construction Quality In 2020, we started construction on the Once Through Steam Generation (OTSG) system on our first Floating Power Plant. To ensure quality and optimise resources needed to build the OTSG system, our marine hull team carried out a Kaizen project to improve the cutting templates to enhance accuracy. Custom-designed jigs facilitated welding and prevented distortion, and optimised the erection sequence to minimise risks related to working from heights. The project improved hull structure construction time by 20 manhours per tonne and raised hull fitting productivity by 30%. It also resulted in higher quality production due to greater dimensional accuracy, while enhancing workplace safety by minimising exposure to work-at-height risks. 91 ANNUAL REPORT 2 0 20 /
