LNG and CNG

Chester Engineers offers full-service engineering and design solutions for the development of liquefied natural gas (LNG) facilities including LNG import/export terminals, peak shavers, as well as small-scale LNG modular systems. Our LNG solutions include:

Environmental Impact Assessment (EIA) Studies

Under Federal regulations, proposed new LNG facilities or proposed modifications to existing facilities are required to submit to the authority having jurisdiction (AHJ) an assessment of the impacts the facility will have on the environment. This requires an evaluation of the impacts of construction and operations of the facility with regards to various environmental concerns of interest to the government including air quality, noise, waterbodies and wetlands, wildlife, and socioeconomics to name a few. The experienced staff at Chester Engineers will prepare the EIA for your LNG facility in accordance with the requirements and expectations of FERC, DOT, US Coast Guard or other national or international agencies.


FEED (Front End Engineering Design) for LNG Facilities

Using the latest proven software in process simulation, design and equipment specifications, Chester Engineers designs and develops the FEED packages for LNG facilities including LNG import/export terminals, peak shavers, and small-scale LNG modular facilities. This essential conceptual design is of paramount importance as it drives not only the design concept, but it is the primary vehicle for estimating facility feasibility and cost. Financial institutions generally require the FEED package in their consideration for funding projects, and regulatory bodies almost always require the FEED package, or aspects of it, for permitting projects. We at Chester Engineers know how to develop FEEDs, and know the importance and value of this fundamental design. Let us partner with you to develop the FEED for your LNG facility in a time-effective manner.


Detailed Engineering Design Review for LNG Facilities

Detailed engineering provides the muscle and brains for FEED packages to become a reality. This stage of the design process accounts for all the details that govern each component, equipment, and system in the design. At times, project Owners do not have the time or the expertise to review detailed designs, and they end up underwriting the cost of unnecessary systems that are incorporated into designs to hide deficiencies in the contractor’s ability to perform detailed engineering analysis, prepare detailed specifications, or to institute good quality control in designs. This weakness in designing systems, although difficult to quantify, can account for as much as ten percent of project budgets and is oftentimes hidden in cost overruns. Chester Engineers offers Detailed Engineering Design Reviews aimed at ensuring efficient designs in the bid to protect Owner’s interests and bottom-line.


Pipeline Design Build Capabilities

Chester offers in-house process design capabilities for the development of natural gas pipelines (including high pressure lines) and compressor stations. We employ integrated civil, structural, electrical and mechanical engineering resources for the design of efficient and environmentally sound pipelines and midstream facilities. Our team utilizes extensive automated systems drafting including 2D and 3D CADD. Offering complete turn-key capabilities, Chester’s design and construction management groups can safely and effectively move gas from natural gas supply basins to your LNG facility.



Fire and Hazard Detection and Mitigation Philosophy Preparation

LNG facilities operating under FERC and DOT jurisdictions are required to present their fire and hazard detection and mitigation philosophy as part of operators permit applications. This process can be a daunting task to inexperienced operators and engineers. At Chester Engineers we have the experience and the know-how to develop comprehensive philosophy documents for Owners and Operators of LNG terminals and peak shavers. The implementation of a carefully defined and developed fire and hazard detection and mitigation philosophy for an LNG facility can be the difference between a safe (and hence successful) operation, and one that ends in disaster. Safety is of paramount importance at Chester Engineers and our fire and hazard detection and mitigation philosophy documents are prepared to protect the Owners, communities, and the environment. We work to keep you and the environment safe.


Fire and Hazard Detection and Mitigation Systems Audit

Existing LNG facilities that are undergoing modifications, upgrades, or have experienced failure events may be required by Owners, Operators, the FERC or the DOT to perform an audit of their hazard detection and mitigation systems. This exercise is generally aimed at:

    • identifying available systems,

    • identifying gaps in the safety provisions,

    • recommending changes or upgrades to systems,

    • addressing areas in the facility requiring additional safety systems,

    • and, identifying the requirements of such systems.

For large complex facilities, this can be quite challenging and not a task for the inexperienced. Medium and small LNG facilities also pose their share of challenges that can easily overwhelm the inexperienced. At Chester Engineers, we have the experience to perform hazard detection and mitigation audits right the first time. We work to ensure the safety of your facility and the environment.


Emergency Shutdown (ESD) System Design

Emergency shutdown systems are incorporated into LNG facilities to initiate safe shutdown of the equipment and systems in failure events. When systems undergo emergency shutdown there are a variety of associated costs and concerns. For this reason, ESD systems must be carefully planned and developed to avoid nuisance shutdowns. Depending on the complexity of the LNG installation, several levels of ESD’s may be required to control the safe shutdown of a facility during emergency events. Experience and safety consciousness must be shrewdly combined in designing ESD systems. Chester Engineers is well positioned to develop the philosophy and design of your ESD system, whether it’s for a LNG terminal, peak shaver, or small-scale LNG production facility.


Installation Engineering Support

Detailed design is actualized during installation and the activities involved during project installation are of paramount importance. The experienced team at Chester Engineers understands this point and we pride ourselves in providing Owners and Operators installation engineering support that is rivaled by none. We provide project management, design reviews, contractor bid evaluations, contractor supervision, project safety monitoring, and act as Owner’s Engineer during project construction. We take the activities involved in installation support seriously, and we subscribe to safety as a foremost requirement.


Equipment Commissioning

Chester Engineers provides equipment commissioning services for compressors, blowers, LNG pumps, exchangers, vessels, dolphins, or transfer piping systems for LNG terminals and peak shaving facilities. We provide detailed review of specifications, installation procedures, drawings, and code-required records and certifications to ensure compliance. We also train Owners, Operators and Contractors in the areas of safety and fire protection which are essential when commissioning equipment in LNG facilities.


Facility Start-Up Support

Major effort is required when starting-up LNG facilities. Some of the major activities to be performed during facility start-up include clean-out, dry-out, purging, equipment and piping cool-down, vessels and tanks cool-down, instrument calibration, controls and communication systems testing, electrical continuity and testing checks, etc. These are generally performed after individual equipment commissioning, when possible. To minimize or avoid accidents and safety events, facility start-up support personnel are required to be experienced in these activities. Chester Engineers provides experienced engineers to support the start-up of any LNG facility.


Facility Commissioning

The commissioning of LNG facilities includes starting-up the facility, and training and acquainting Owners or Operators on how to safely control its operation. This can involve several months, and even years, depending on the size and complexity of the facility. Once systems start-up and Owners or Operators have gained confidence in operating the systems (or parts thereof), a handoff from the designer to the Owner or Operator is performed. This generally includes handing over all design documents and operations procedures to the Owner or the Operator of the facility. This process and the voluminous documentation involved can easily overwhelm both the design team handing over the documents as well as the Owners and Operators receiving custody of the documents. Chester Engineers, banking on its expertise in this area, can facilitate and remove much of the complexity from this process. We are experienced in commissioning activities and offer Owner’s Engineer services in this area. Our team will take the worry out of documentation handling so you can focus on operations.


HAZOP Studies

HAZOP studies address the hazards associated with the design and operations of a facility. LNG facilities require qualitative HAZOP evaluations to identify safety or environmental effects that could manifest during operations. These studies generate recommendations that aim to prevent the safety concerns identified in designs. They also establish additional safety controls or instrumentation that could mitigate or eliminate these concerns. Chester Engineers can facilitate HAZOP studies for any design and has the expertise to review, evaluate, ask the tough questions that are required, and prepare professional HAZOP reports for the design of LNG facilities.
