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.
PT South Sulawesi LNG Facility
Energy World Corporation
PT South Sulawesi LNG Facility
Front end engineering design (FEED) for the balance of plant for this 2.0 (expandable to 5.0) MTPA gas liquefaction and marine export facility.
Freeport LNG Project
Freeport LNG
Freeport LNG Project
USA, Texas
Pre-FEED services investigating the design and regulatory requirements for converting the existing LNG import terminal to a world class LNG production and export facility. This was followed by the award of the Balance of Plant FEED for the 13.4 MPTA liquefaction facility.
Magnolia LNG Liquefaction FEED
LNG Limited
Magnolia LNG Liquefaction FEED
USA, Louisiana
Front end engineering design (FEED) and compilation of the Federal Energy Regulatory Commission (FERC) Resource Report 11 and 13 for the proposed 8 MTPA LNG production and export facility. This included siting analysis (including vapor dispersion and thermal radiation exclusion zones, overpressure modeling, and toxicity modeling), NFPA 59A Fire Protection Evaluation, hazard detection, control, firewater system design details, and other required documentation. CH·IV also oversaw the preparation of the LNG tank design, marine facilities design and geotechnical analysis.
LNG Import Terminal
LNG Import Terminal
Puerto Rico
Owner’s engineering support including preparation of FEED for terminal expansion and LNG trailer loading station, procurement specifications for major equipment, EPC contractor scope of work, and oversight of detailed design.
