IGAS has successfully completed a major Nitrogen Supply Scheme project for BOC Gases. This project was a major challenge to IGAS due to the size and complexity of the project having to be undertaken within a 16 week period.
The Nitrogen Supply Scheme provides high-pressure (110 Barg) gaseous nitrogen to Excelerate Energy from BOC’s production facility at Teesport. The nitrogen is conveyed from Teesport to the Excelerate jetty via a buried 8″ NB pipeline approximate length 3000 metres. The distribution system at the end of the nitrogen pipeline injects the nitrogen into the LNG gas stream.
Excelerate Energy (BOC Client) will re-inject re-gasified LNG into the UK National Grid Transmission System (NTS) during peak demand periods when the UK NTS is stretched and when market pricing is expected to be at peak levels. Re-gasification will take place on-board ships operated by Excelerate Energy, which will be docked at a refurbished Shell jetty on the South side of the River Tees. The gaseous natural gas is piped at high pressure under the river Tees through a new 24″ NB high-pressure pipeline to the NTS grid connection point operated by PX Holdings Limited at Seal Sands. Certain sources of LNG require nitrogen injection to adjust the gas specification to be compliant with tight UK requirements.
The turnkey project involved taking the Principle Contractor, role under CDM (1994) regulations, included equipment procurement and installation contracts for Mechanical, Electrical/Instrument, Super Insulated vacuum Line and Civils. Also, peripheral services, including: HAZOP studies; Risk Assessment; and all drafting services.
The scope was very wide ranging from installation and NDT testing of piping systems to the provision of SCADA and PLC software control.
IGAS were responsible for design, installation, commissioning and implementation.
All work was completed within budget and to timescale resulting in a completely satisfied customer.
