Baseline asset condition and Condition survey - Tanks and Planned Preventative Maintenance

• Duration: 1 year

The initial phase includes the creation of baseline asset information and condition surveys for primary, secondary, and tertiary containment structures. This information is to be generated in a consistent format across the engineering sites to enable risk assessment and prioritisation of any subsequent works. Scope of Works needed: -100% Detailed asset capture A detailed asset register is to be compiled on completion of works to list all equipment not limited to but including: Tanks Pipework Pumps Valves Gauging Alarm Systems Gantry Systems - Reports

• Duration: 2 year

Over the past few years NTL has delivered to a project to establish the baseline condition of its assets and develop a portfolio of baseline asset information. This project saw the delivery of works to the below standards: -Tanks – Out-of-service inspection in line with EEMUA 159 and API 653. -Bunds – Bund compliance inspection using CIREA 736 Guidance. -Pipework – Pipework integrity assessment in line with API 570. -Separators – 5-yearly separator inspection in line BS EN 858. NTL intend on maintaining compliance with these standards and implementing best practice in relation to asset maintenance. This specification is to ensure NTL continues to deliver its maintenance obligations and ensure adequate integrity of its primary, secondary and tertiary containment for substances hazardous to the environment up until 31st March 2026.
