The Gas Standards Office (GasSO) of the Electrical and Mechanical Services Department (EMSD) reviewed the Code of Practice (CoP) for Hong Kong LPG Industry, Module 2 - Underground LPG Pipework, in 2023/2024. The goal was to improve gas safety standards by taking into account the latest technological development, international standards and the experience gained by the local LPG Industry over the years.

The CoP outlines the safety standards, guidelines, and best practices for the design, installation, testing and commissioning, operation and maintenance of underground LPG pipework in Hong Kong. Recognising the benefits of using Polyethylene (PE) pipe as demonstrated by the industry experience, the revised CoP places emphasis on promoting the use of PE pipe for new LPG installations while imposing enhanced safety requirements on steel pipelines. The revised CoP is expected to enhance the overall safety and reliability of Hong Kong’s underground LPG distribution networks.

The CoP Module 2 (Issue 2) was issued in April 2024 and is now available for download at the EMSD’s website: https://www.emsd.gov.hk/en/gas_safety/publications/codes_of_practice/index.html

The Electrical and Mechanical Services Department (EMSD) awarded NEC4 DBO contracts to Paul Y.-Big Four Joint Venture and CRBC-QH-REC-QTEC Joint Venture for the design, construction and operation of DCS in Tung Chung New Town Extension (East) (TCNTE-E) and Kwu Tung North New Development Area (KTN NDA) in September 2023 and February 2024 respectively. DCS is a large-scale centralised air-conditioning system which is more energy efficient than individual systems, supporting the government's goal of carbon neutrality by 2050.

The DCS in TCNTE-E has a cooling capacity of 123 MW refrigeration using seawater for heat rejection, while Phase 1 DCS at KTN NDA has a cooling capacity of 46 MW refrigeration using fresh water cooling towers for heat rejection.

NEC4 DBO contract form emphasises collaboration and mutual trust between parties to minimise disputes and expedite project delivery in a timely manner to tie in with the commissioning of the development.
