Issues regarding the substitution of specifications for the commissioning of large and medium-sized units in the chemical industry
Thread Content
The HGJ-231-1990 Specifications for Commissioning of Large and Medium-Sized Units in the Chemical Industry has been replaced by HG 20231-2014 Specifications for Commissioning of Chemical Industry Construction Projects. However, elements such as the division of tasks for pre-commissioning are not included in the replacement standard; it is unclear whether these aspects are addressed in other standards or have been removed. If this is not specified in the contract, it may lead to disputes and conflicts during the commissioning process. How should such problems be eliminated?

As long as you meet the requirements and the regulations permit it, you can do it; otherwise, it will be illegal for you to do so! Whether it is construction or operation. Basically, the dividing line lies at mechanical completion (interim handover); before that, it is the construction site, and everything falls under the responsibility and scope of work of the contractor, designer, and constructor ； After that, it’s the chemical plant – everything falls under the owner’s responsibility and scope of work, except for any remaining outstanding items. Pre-commissioning falls under the category of construction, while cold commissioning and hot commissioning fall under the category of operation.
