Client: SMC Marine
Location: New Sydney Fish Markets → Glebe Island, Sydney
Project Type: Contaminated Steel Pipe Cleaning – HPWJ & ACM Remediation
Silver Raven was engaged by SMC Marine to assist with the decontamination of steel pipe piles extracted from the seabed at the New Sydney Fish Markets construction site. Each pile measured approximately 15 meters in length and 1 meter in diameter, and had been removed and transported by barge to a temporary works area at Glebe Island for inspection and further processing. Following removal, SMC Marine identified that the internal cavities of the piles were possibly contaminated with asbestos-containing materials (ACM), as well as accumulated loose debris from their time in service.
Due to the hazardous nature of the contamination, Silver Raven was contracted to undertake specialist internal cleaning and remediation of the pipe piles to ensure they met safety and environmental standards prior to disposal or reuse. The work required a safe, thorough, and fully compliant cleaning solution that could operate within the confined interiors of the steel pipes.
To complete this task, Silver Raven deployed a custom-engineered High Pressure Water Jetting (HPWJ) system featuring a tank head configuration capable of high-impact horizontal internal cleaning while simultaneously containing and capturing contaminated debris. A bespoke centralising fixture was fabricated in-house to align and stabilise the HPWJ tank head within the narrow steel pipe bores. This ensured consistent 360-degree cleaning coverage along the entire internal length of each pipe, regardless of alignment or pipe ovality.
