The following describes the typical services that CH·IV would provide during the various stages of project development:

Site Selection

  • Research location of resources required to support LNG development (land, marine access, pipeline take-away capacity, electrical transmission access, zoning, etc.),
  • Map review of potential sites,
  • On-site survey of potential locations,
  • Review of potential thermal exchange partners, and
  • Evaluation and ranking of potential sites.

Site Due Diligence

  • Collect available information concerning previous site use, including geotechnical information and sub-surface obstructions,
  • Collect information concerning site water resources, including existing wells, surface waters, and municipal/industrial water sources,
  • Collect marine access details such as existing traffic, mean low water draft available, air draft obstructions, channel width, etc.,
  • Identify applicable zoning and permitting requirements for the site,
  • Collect information on the potential thermal exchange for the site,
  • Review gas (and electric) transportation capacity in the area of the site,
  • Characterize the ability of the planned facility to fit the available land, and
  • Evaluate the major impacts on project feasibility to determine the acceptability of the project site for development.

Conceptual Engineering

  • Prepare alternative designs and perform initial sizing of components,
  • Develop heat balance for site,
  • Prepare conceptual engineering report including process flow diagrams and material balances, detailed project schedule, construction cost estimate, and O&M cost estimate,
  • Support development of detailed project proforma and financing approval,
  • Prepare project description and inputs for air and water permit modeling, and
  • Coordinate site land survey and geotechnical sampling performed by others.

Preliminary Engineering

  • Obtain specific component operation characteristics for site from vendors
  • Develop project specific specification for major components,
  • Coordinate development of additional owner permits and update information in existing permits, as necessary,
  • Prepare site drainage and surface run-off containment drawings,
  • Detail interface requirements with connecting pipelines utilities or thermal exchange partners,
  • Finalize component selection, project cost estimates, and project schedule,
  • Prepare EPC (engineer, procure, and construct) specification,
  • Define contractor guarantees for facility performance (LNG tank heat leak, facility fuel utilization, total facility electrical power consumption), emissions control, maintenance, operation, documentation, and training,
  • Prepare preliminary engineering report documenting details of plant design, and
  • Provide technical support to evaluate bids and award EPC scope of work.

Detailed Design and Construction Support Engineering

  • Perform technical review of specifications, drawings, and engineering calculations performed by EPC,
  • Provide on-site engineering support of construction activities, including initial site preparation,
  • Technical resolution of problems during unit construction,
  • Provide independent assessment of project schedule and corrective actions to ensure schedule compliance,
  • Review and approve proposed field changes to design,
  • Maintain project files during construction and review EPC as-built information,
  • Evaluate change orders to EPC scope, and
  • Coordinate activities between EPC, vendors and other organizations.

Start-up Support Engineering

  • Technical resolution of problems during unit start-up,
  • Provide independent assessment of activity schedule during start-up,
  • Review test procedures for acceptance testing of performance and emissions,
  • Review results of acceptance testing for performance and emissions,
  • Prepare and provide operator/technician training, and
  • Maintain punchlist of items to be corrected by the EPC.
