Outcomes

Year 2023/24

1. Oil sample analysis and hydrocarbon profile determination

Aim: To assess the condition of the oil and determine the profile for the bacteria.

Success criteria:

• Accurate identification of contaminants, including PCBs.
• Understanding the hydrocarbon profile to guide decontamination efforts effectively.

Outcomes:

• Hydrocarbon profile determined through analysis provided insights into the types and present concentrations.
• PCBs not found.
   

2. Upgrade of ODB System modules for increased voltage 
 Aim: To upgrade existing ODB System modules to accommodate requirements up to 400kV.

Success Criteria:

• Successful modification of existing modules to enhance voltage capabilities.
• Ensuring compatibility and functionality of upgraded modules with the ODB System.

Outcomes:

• Rigorous testing and modification of existing ODB System modules were conducted to increase voltage capabilities.
• Compatibility and functionality of upgraded modules were verified through performance testing and simulations.
• Modification process documented successful upgrades. 
   

The outcomes demonstrate significant progress towards achieving project aims and success criteria. The analysis of oil samples provided critical insights into the hydrocarbon profiles, guiding the bacterial degradation efforts. Additionally, successful upgrades of ODB System modules further align the project with its objectives and contribute to its overall success.

Lessons Learnt

Co-ordination to ensure electricity supply and chlorine free tap water access requirements need to be understood and prepared in advance based on project specifications and requirements. 

Clearly defining responsibilities for tasks such as initial oil-purging, tank emptying, cable head preparation, and bypasses is essential to ensure timely completion. It's also vital to prioritise coordination and approvals for ODB module placement to prevent delays and ensure compliance with regulatory requirements.
