Infrastructure Management for Power Capture in the Evaluate stage

Objective 

• Evaluate the options and select the preferred strategic configuration that should best support the business case (Part A) for off-site infrastructure.
• Further develop the preferred configuration to a sufficient level of confidence to justify committing funds for the next stage of project development (Part B)
• Commence  discussions with infrastructure providers towards developing term sheets for supplies and permits to connect
• Develop a detailed plan for the next stage of the project

On-site infrastructure is covered under Power Plant (including capture)

• Hazard & Risk reviews
• Option & Topic Study Reports
• Class 4 Capital and Operating Costs
• Options Evaluation Report
• Multi Criteria Assessment Report
• Option Selection Report
• Part B
• Design Control Plan
• Updated Functional Specification
• Basis of Design
• Design Criteria
• Basic Engineering Package for preferred configuration
• Hazard Study 2
• Preliminary term sheets for infrastructure services
• Updated Risk Register
• Class 3 Capital and Operating Costs
• Independent Peer Review
• Prefeasibility Study Report
• Forward Work Plan

Tasks

Specific tasks for Part A include the following:

• Confirm or update boundary conditions, strategic decisions, themes and alternatives to be evaluated.
• Prepare a functional specification detailing the boundary conditions, expectations, assumptions and performance requirements for the infrastructure.
• Establish option evaluation criteria for example supply reliability, security, operability, maintainability constraints and/or benefits, capital costs and schedule to implement, support services, siting considerations, hazards and risks,
• Assess alternative options for each infrastructure requirement e.g.
  • power – consider both operational and construction needs
  • raw water and storm water also consider both construction and operational requirements
  • cooling water associated with a sea /fresh water cooling option if relevant
  • steam (if by a third party)
  • road access for equipment delivery, construction and operations
  • rail/road/pipeline for fuel supplies,
  • logistics arrangements for other supplies and waste disposal and
  • connection for HV power export
  • Review combination configurations and integration with the power capture plant and include, security and environmental considerations, business opportunities, risks and constraints.
  • Carry out initial infrastructure corridor studies
  • Assess likely locations for infrastructure facilities e.g. water intakes /pump stations, wastewater/cooling water disposal, waste management, rail/road/pipeline tie-ins with existing and compounds etc., Consider environmental and community impacts, fire, explosion, loss of containment, occupational health and safety, access, emergency response, security, cost and time particularly for obtaining land access.
  • Evaluate legal, regulatory and permitting issues
  • Review operational and maintenance requirements highlighting any special requirements and any availability constraints especially during start-up, ramp-up and shutdown,
  • Review possible commercial requirements including any likely term sheet conditions
  • Prepare Class 4 Capital and Operating Cost estimates and likely implementation schedule
  • Carry out a multi criteria assessment
  • Carry out an independent peer review
  • Select a preferred option for each required  infrastructure  and
  • Prepare a Option Selection Report

Specific tasks for Part B include the following

• Update the functional specification including minimum standards for key engineering deliverables,
• Engage any engineering services providers
• Carry out updated framing and alignment workshops, engineering standards selection, design to capacity and lessons learnt reviews
• Update the design basis and design control plan based on the preferred options
• Undertake preliminary process simulation / modelling to optimise integration of power-plant and capture plant where necessary for basic design.
• Upgrade infrastructure corridor studies for preferred options and prepare preliminary alignment drawings.
• Develop layouts preliminary arrangements for water intakes, wastewater/cooling water disposal, waste management, rail/road/pipeline facilities, tie-ins and compounds  etc. 
• Carry out waste minimisation, energy utilisation and value engineering reviews
• Develop the Basic Engineering Package for the preferred configuration including:-
  • Alignment drawings
  • Preliminary sections and key details
  • Preliminary flowsheets and utility balances
  • Materials selection criteria, Materials selection charts
  • Preliminary equipment list
  • Preliminary bulk materials / commodity take-offs
  • Equipment outline specifications

  • Preliminary single line and connection diagrams
  • Preliminary control system, data collection functional specification
  • General arrangements and layouts for facilities
  • Business systems impacts
• Review the engineering deliverables
• Carry out Hazard 2 studies and risk reviews
• Commence preliminary connection and access enquiries
• Commence environmental impact studies,
• Prepare preliminary operations plan including operations and maintenance strategy, likely workforce requirements availability and training needs.
• Commence commercial arrangements including enquiries towards term sheets for fuel supplies, waste disposal, utility supplies and services,
• Prepare Class 3 Capital and Operating Cost estimates and likely implementation schedule
• Carry out an Independent Peer Review
• Prepare a Study Report
• Prepare forward work plan for the Definition Stage
