EOI for Wivenhoe OT Network - Detailed Network Design and Support Services

This is a call for expressions of interest only and is intended to assist the Customer to understand the capability of the market to meet the Customer’s objectives and requirements to identify potential suppliers in the market.

CleanCo is conducting an upgrade project to refurbish the Wivenhoe Power Station Operational Technology (OT) network architecture.

The Wivenhoe Power Station control system network was developed in the first decade of this century and whilst functional requires significant refurbishment to meet contemporary control system network practices and CleanCo’s responsibilities under the AESCSF and associated legislation.

CleanCo seeks to develop a new network architecture for Wivenhoe Power Station, based on a high-level design that had been developed and the requirements borne from a similar upgrade project underway at one of CleanCo’s other generation sites.

The high-level objective is to introduce a level of standardisation across CleanCo hydro-fleet for the control system network design whilst accounting for site specific requirements.

In scope:

The scope of this body of work is to provision the development of an OT Network Detailed Design and with the follow-on project phases (testing, installation and commissioning). The scope of works is divided into two non-separable portions, which at a high level are:

1. "Portion 1A" (Fixed Price) – Development of a Detailed Network Design from the High-Level Design and reflect inputs from the CleanCo’s engineering team and external contractors. This portion is the bulk of the project and consists of largely front-end engineering and design (FEED) works to develop the Detailed Network Design.

2. "Portion 1B" (Schedule of Rates) – Provision of ongoing design input, assistance and support to the works for the remainder of the project, though having the Detailed Network Design team available on an as-required basis to update the design and guide the works to a successful completion.
