The company works to meet the world’s growing demand for energy by exploring for oil and natural gas; refining and marketing gasoline and producing chemicals.
The company neeeded the removal of their now redundant tetraethyl lead storage and blending facilities at their Pembroke Refinery.
The TEL facility had to be completely removed and disposed of. All highly hazardous and toxic materials and waste products had to be removed in a safe and timely manner.
All project, site and legal requirements had to be met. All assets had to be protected. There had to be little or no impact on the customer’s other daily activities during the execution phases of the project.
This project had 6 major challenges:
• To remove, transport and dispose of the Tetraethyl lead liquids and residues. No incinerator within the UK could destroy the waste materials and exporting such a hazardous and toxic chemical has its own complications which could mean that the chemical could reside in unsecure storage for months prior to exportation.
• The weigh tank that was situated within the confines of a blast proof building had to be removed. The roof had to be removed. However, the concrete bison beams that made up the roof had their integrity compromised. The tow of the beams had been cut to allow access of the barometric leg and vent loop to go through the roof into the vessel.
• The lifting procedures for the three vessels once drained.
• The confined space entry required.
• The removed of all liquid and scale during the tank cleaning phase.
• The conversion of organic lead residue within the internal steel shell to inorganic leads to enable transport and disposal by means of a smelting facility.
• To ensure the project went smoothly communication and collaboration were essential. It was imperative from the outset that all persons who would be directly or indirectly impacted by this project continuously informed. Everyone knew what was happening, who was involved and who was affected. This included external contractors who were supporting Crest throughout the project.
• Daily briefings were given every morning about the work planned, health and safety before starting work. All activities, concerns from previous day along with all new or required communication were communicated.
• Daily work face audits were also carried out, documented, filed and comments reported at the morning safety brief.
• The lead storage and blending facilities were successfully decommissioned and decontaminated in a project that took x weeks.
Peace of mind that a highly toxic and hazardous facility is no longer a potential threat.
Cheaper insurance premiums and release of a brown field area for further construction of new facilities were all considerable customer benefits.
“Crest’s skills and project management were awarded the very next project without tender at the Richmond Refinery California.”
“Our client’s Pembroke’s project team were awarded safest project of the year throughout the client’s worldwide operations.”
