Notice Information

Notice Title

East Coast Hydrogen FEED Design & PEC Work Packages

Notice Description

NGN is seeking to appoint one or more experienced consultants to deliver key work packages for the East Coast Hydrogen (ECH) Front-End Engineering Design (FEED) project. This project forms a critical part of NGN's strategy to enable the transition to a low-carbon energy system, supporting the UK's net zero targets by 2050. The ECH initiative aims to repurpose and expand existing gas infrastructure to transport hydrogen across the region, creating a reliable and scalable hydrogen network to facilitate hard-to-electrify industrial processes.

Lot Information

LOT 1 - Engineering Design

The purpose of this work is to deliver front-end engineering design for the ECH project. This package of works will expand and develop the Pre-FEED engineering to develop the technical requirements and preliminary designs to define the scope, cost and schedule of the project before committing to full execution. The purpose of this phase of the project is to establish a clear project scope, develop the design documentation to enable accurate cost estimate, identify the risks and constraints and prepare the basis for procurement and construction planning. It is anticipated that the required design works will be undertaken to varying levels of detail, dependant on the certainty of the network section, ranging from FEED level design based on location specific assets to utilisation of standard design information for less certain route corridors. The network extent is yet to be defined however it is anticipated it will be in the magnitude of the Pre-FEED. The extent of network design will be dictated in the Request for Proposal stage.

Renewal: 1 year extension provision

LOT 2 - Planning, Environmental & Consents

Pre-FEED studies have identified the potential for 1-2 DCOs and several TCPA applications to varying maturity, noting that a number of those may benefit from Permitted Development Rights. As such the below scope of works is set out for standard requirements for a DCO and TCPA application in isolation. More detail will be provided at RFP stage. Overall project management will be undertaken by NGN; however, the PEC Consultant will be expected to include project management processes, document control, interface management, risk management and technical assurance processes.

Renewal: 1 year extension provision

This package of works will expand and develop the Pre-FEED engineering to develop the technical requirements and preliminary designs to define the scope, cost and schedule of the project before committing to full execution. The purpose of this phase of the project is to establish a clear project scope, develop the design documentation to enable accurate cost estimate, identify the risks and constraints and prepare the basis for procurement and construction planning. It is anticipated that the required design works will be undertaken to varying levels of detail, dependant on the certainty of the network section, ranging from FEED level design based on location specific assets to utilisation of standard design information for less certain route corridors. The network extent is yet to be defined however it is anticipated it will be in the magnitude of the Pre-FEED. The extent of network design will be dictated in the Request for Proposal stage.",
