PNG LNG Liquefied Natural Gas Extraction Project

In the energy-rich landscape of Papua New Guinea (PNG), the Silver Fern Farms PNG LNG liquefied natural gas extraction project stands as a landmark initiative, driving the country’s industrial development and energy export capacity. Around 2023, this large-scale LNG extraction project faced critical challenges in sourcing high-quality, compliant electrical cables to support its safe and efficient operation. As a professional wire and cable exporter with years of experience in international engineering projects, Dongguan Greater Wire & Cable Co., Ltd. stepped in to provide tailored solutions, supplying Medium Voltage Cable, Earthing Cable, and Elastomer Cable that perfectly met the project’s stringent requirements. This case study details how we addressed the client’s core pain points, leveraged our advantages, and delivered a successful cooperation that ensured the smooth progress of the PNG LNG project.

1. Challenges in PNG LNG Extraction Operations

Silver Fern Farms’ PNG LNG project is located in the Southern Highlands of Papua New Guinea, a region known for its complex terrain and harsh environmental conditions—high humidity, frequent rainfall, and extreme temperature fluctuations. As a key part of the country’s energy infrastructure, the project involves natural gas extraction, processing, and liquefaction, all of which rely heavily on stable and safe electrical power transmission. The client’s original plan to source cables locally and from other suppliers failed to meet the project’s standards, leading to three core pain points that threatened to delay the project timeline.

First, the client struggled to find cables with international safety certifications. PNG’s LNG industry follows strict safety regulations, and the project required cables that meet global standards to ensure operational safety. Many local suppliers could not provide valid certification, while some international suppliers only offered cables with incomplete certification, which could not pass the project’s safety inspection. Second, the project needed a full range of cable types to cover different scenarios—from medium-voltage power transmission to equipment earthing and flexible connection in harsh environments. Most suppliers could only provide one or two types of cables, requiring the client to cooperate with multiple suppliers, which increased procurement costs and management complexity. Third, the client lacked confidence in suppliers without experience in large-scale LNG or mining projects. The harsh environment of the PNG LNG site demands cables with strong durability and adaptability, and inexperienced suppliers could not guarantee that their products would withstand long-term use in such conditions.

After extensive market research, the client contacted Dongguan Greater Wire & Cable Co., Ltd., hoping to leverage our professional capabilities, complete product range, and rich project experience to solve these challenges.

2. Matching Cable Types to Project Needs

After in-depth communication with the client, our team conducted a detailed analysis of the PNG LNG project’s operational scenarios, environmental conditions, and safety requirements. We customized a comprehensive cable solution centered on three core products—Medium Voltage Cable, Earthing Cable, and Elastomer Cable—each designed to address specific pain points and adapt to the project’s unique needs.

2.1 Medium Voltage Cable: Stable Power Transmission for Core Equipment

The LNG extraction and liquefaction process relies on large-scale equipment (such as compressors, pumps, and liquefaction units) that requires stable medium-voltage power supply. We recommended our XLPE-insulated Medium Voltage Cable (voltage grade: 11kV, conductor cross-section: 35mm²-185mm²), which was chosen over other options for three key reasons. Unlike traditional PVC-insulated medium-voltage cables, our XLPE-insulated cables have better thermal stability and electrical insulation performance, able to withstand the high temperature generated by long-term operation of LNG equipment (up to 90℃ under normal operation) without insulation aging or breakdown. Additionally, the cable is equipped with a steel tape armoring layer, which enhances its mechanical strength and resistance to external damage—critical in the PNG project’s rugged construction site where cables may be exposed to mechanical impact or burial. Finally, our Medium Voltage Cable is fully compliant with IEC 60502-2 standards and holds the saa power cable certification, ensuring it meets the project’s strict safety and quality requirements.

2.2 Earthing Cable: Safe Protection Against Electrical Hazards

Electrical safety is a top priority in LNG projects, as gas leaks combined with electrical sparks could lead to catastrophic accidents. The client needed an earthing cable that could effectively discharge static electricity and fault current, ensuring the safety of equipment and personnel. We provided our Earthing Cable (model: ZA-BVR, conductor material: tinned copper, cross-section: 16mm²-50mm², color: yellow-green as required by international standards), which outperforms ordinary earthing cables in several aspects. Unlike common copper-clad steel earthing cables, our tinned copper Earthing Cable has better electrical conductivity and corrosion resistance, able to adapt to PNG’s high-humidity and corrosive environment without rusting or losing conductivity over time. The cable’s flexible structure also makes it easy to install in complex terrain, ensuring full contact between the earthing system and the ground to achieve effective earthing protection. Moreover, the cable meets AS/NZS 5000.1 standards, aligning with the project’s safety certification requirements.

2.3 Elastomer Cable: Flexible Adaptation to Harsh Environments

The LNG project’s on-site equipment (such as mobile detection devices and temporary power supplies) requires flexible cables that can withstand frequent bending, high humidity, and extreme temperatures. OurElastomer Cable (insulation material: EPR synthetic elastomer, voltage grade: 0.6/1kV, conductor cross-section: 4mm²-25mm²) was the ideal choice for this scenario. Compared with traditional rubber cables, our Elastomer Cable uses advanced synthetic elastomer insulation, which offers superior flexibility, cold resistance, and anti-aging performance—remaining flexible even at -40°C and resisting UV radiation and ozone erosion in outdoor environments. The cable’s outer sheath is wear-resistant and oil-resistant, protecting the inner conductor from damage during equipment movement or construction activities. Additionally, the elastomer material is non-toxic and environmentally friendly, meeting the environmental protection requirements of industrial projects in Papua New Guinea.

3. Centered on SAA Certification and Strict Quality Control

The client’s greatest concern about cable selection was safety, which is why our saa power cable certification and strict quality control system became the key to winning their trust. SAA certification is a globally recognized safety certification for electrical products, especially in the Asia-Pacific region, and it strictly tests the electrical performance, flame retardancy, and durability of cables—ensuring that products meet the highest safety standards for industrial use. All three types of cables we provided have passed SAA certification, as well as IEC and AS/NZS standard tests, proving their reliability in harsh industrial environments.

In addition to certification, we implemented strict quality control throughout the production process to ensure product consistency. From raw material selection (using high-purity copper conductors and high-quality insulation materials) to production processing (adopting automated extrusion and vulcanization technology), and finally to finished product testing (conducting electrical performance, mechanical performance, and environmental adaptability tests), every link was supervised by professional technicians. We also provided the client with detailed test reports for each batch of cables, allowing them to verify the quality and safety of the products at any time. This rigorous quality control system not only met the project’s safety requirements but also avoided potential safety hazards caused by inferior cables, such as short circuits or fires.

4. Efficient Coordination to Ensure Project Progress

Understanding that the PNG LNG project had a tight timeline, we prioritized efficient delivery while ensuring product quality. After confirming the order, we optimized our production schedule, allocating dedicated production lines for the project to shorten the production cycle. We also established a special logistics team to handle the export process—including customs declaration, documentation, and shipping arrangements. Considering Papua New Guinea’s complex transportation conditions (limited land transportation and reliance on port shipping), we chose a reliable international shipping company with experience in PNG routes, ensuring that the cables were transported safely and on time.

During the delivery process, we maintained real-time communication with the client, providing regular updates on production progress, shipping status, and expected arrival time. We also prepared detailed installation guidelines for each type of cable, including installation precautions, technical parameters, and maintenance methods, to help the client’s construction team install the cables efficiently. Our after-sales team was also on standby to provide timely technical support, answering any questions the client had during installation and commissioning. This efficient and thoughtful delivery and after-sales service ensured that the cables were installed and put into use smoothly, without delaying the project’s progress.

5. Win-Win Cooperation and Client Recognition
