Site Preparation and Decommissioning
Located near active pipe racks, railway spur lines, and plant roadways, the plant's warehouse and auxiliary buildings remained operational throughout the project. Shell had initially decommissioned the plant, removing and disposing of process chemicals through isolation, purging, and cleaning all equipment, tankage, and piping. Additionally, they performed the disconnection and air-gapping of all feed, product, and utility lines from adjacent pipe racks.

Delsan-A.I.M. verified that all disconnects and air-gapping were complete and conducted a thorough site inspection to ensure the removal of residual products before proceeding with demolition.

Demolition Process
The final decommissioning work carried out by Delsan-A.I.M. involved the abatement of hazardous materials such as asbestos before starting the demolition operations. The demolition itself was performed using mechanical methods, including large excavators equipped with specialized attachments, in accordance with engineered guidelines. For structures that could not be safely demolished using conventional methods due to their height or proximity to active services or facilities, they were either lowered in sections using a mobile crane and small demolition equipment or carefully dropped following detailed engineered procedures.

All demolition materials were transported to licensed recycling and disposal facilities, with concrete rubble crushed, stockpiled, and reused on-site.
