Managing distressed cargo and hazardous waste: A case study at Southampton Docks

Published: 28 November 2023

Cargo management can be a daunting task, especially when faced with distressed cargo and hazardous waste. In August 2023, DP World Southampton encountered a challenging situation at Southampton Docks when two 40 foot Refrigerated ISO containers arrived damaged, each containing 25,000kg's of raw pork meat products. These "Reefers" had been left unrefrigerated for an extended period, posing health hazards and logistical challenges in transporting the containers safely. The task was clear: devan, decontaminate, and dispose of this cargo while ensuring the safety of all involved.

Project overview

The condition and extent of decomposition within the containers were unknown, but an initial site visit revealed leachates, flies, and a foul smell. These challenges prompted Adler and Allan, appointed by DP World Ltd, to determine the projects requirements and propose a safe system of work.

Our solution

To address this situation, several measures were implemented:

  • Safety first: The safety of the response teams was paramount. Following security checks and site safety induction, a Risk Assessment Method Statement (RAMS) for shipside decontamination operations was submitted for review and approval, and a permit-to-work (PTW) was issued.
  • Containment and odour control: The team cordoned off the work area using spare 40 foot ISO shipping containers, serving as a safety barrier, screen, and windbreak. Odour suppression systems were also used to minimize unpleasant smells.
  • Bunded areas: Bunded areas for each container were established, creating hot, warm, and cold working zones. This ensured containment and safety during the operations.
  • Waste management: Contaminated solids were recovered and double-bagged, minimizing the risk of leakage. They were placed into open-top Intermediate Bulk Carriers (IBC's), serving as both a suitable container for onward transport and a bund for added protection. Liquid waste was transferred to 205-litre drums for incineration.
  • Disinfection: Both containers were disinfected with Sodium Hypochlorite and pressure washed.
  • Regulatory compliance: All waste was segregated and treated in line with the principles of the waste hierarchy and regulatory guidance, ensuring compliance with relevant legislation.

Outcome and results

The results of this comprehensive approach were outstanding:

  • The response teams safely devanned the two containers using air-supplied breathing apparatus.
  • Hazardous solid waste was double-bagged and placed into IBC's, further reducing the risk of contamination.
  • Liquid waste was safely transferred and disposed of via incineration.
  • All waste was classified as Category 2 Animal Bi-Product (ABP) and disposed of in compliance with relevant regulations.
  • A total of 78 IBCs of contaminated solid waste and 5 drums of contaminated liquid were safely disposed of.
  • Importantly, there was no release of product to the environment during recovery operations, and no lost time safety incidents occurred throughout the project.
“Everything went well with the team, very professional throughout, and kept us up to date with the proceedings.”
