Tokelau Ship-to-Shore Project Power System Upgrade

In recent years, Tokelau, a remote island nation in the Pacific Ocean, has been accelerating the upgrade of its maritime infrastructure to support its growing shipping and logistics needs. As part of New Zealand’s support for Tokelau’s infrastructure development, the “Ship-to-Shore” power system upgrade project was launched around 2023 to address the outdated power supply issues of the island’s port terminals. As a professional cable exporter with rich experience in international projects, Dongguan GERITEL Electrical Co., Ltd. successfully provided customized cable solutions for this project, solving the core pain points of the client and establishing a long-term cooperative relationship. This case study details how our high-quality cables, includingMedium Voltage Cable, SWA Cable, andElastomer Cable, supported the smooth completion of Tokelau’s Ship-to-Shore power system upgrade, highlighting the value of our saa approved cable and professional services.

1. Tokelau’s Ship-to-Shore Power System Pain Points

Tokelau’s main port is an important hub for the country’s maritime transportation and supply, undertaking the task of connecting ships and onshore facilities. The original power supply system of the port had been in use for many years, and with the increase in shipping volume and the upgrade of port equipment, a series of prominent problems gradually emerged, becoming a key bottleneck restricting the port’s efficient operation.

The client’s core pain points were mainly reflected in three aspects. First, the original cables lacked professional certification and could not meet the strict safety standards of marine and port power supply. Tokelau is located in a tropical marine climate, with high temperature, high humidity, and strong salt spray corrosion all year round, which puts extremely high requirements on the corrosion resistance and weather resistance of cables. The original common cables were prone to insulation aging and conductor corrosion after long-term use, leading to frequent power failures and potential safety hazards. Second, the variety of cables was single, and it was impossible to match the different power supply needs of the Ship-to-Shore system. The project involved high-voltage power transmission from onshore power stations to port terminals, low-voltage power supply for terminal equipment, and flexible connection of mobile power devices, which required cables of different types and specifications to cooperate with each other. Third, the quality of the cables was unstable, with problems such as insufficient current-carrying capacity and poor mechanical strength. During the peak period of port operation, the cables often overheated, affecting the normal operation of the power system, and even threatening the safety of personnel and equipment.

In addition, Tokelau’s geographical location is remote, and the port can only be reached by barge, which makes the transportation and replacement of cables extremely inconvenient and costly. Therefore, the client urgently needed a reliable cable supplier that could provide certified, comprehensive, and high-quality products, and could guarantee the stability and durability of the cables in harsh marine environments, while providing professional technical support and efficient delivery services.

2. Tailored Cables for Tokelau’s Special Needs

After in-depth communication with the client and a comprehensive investigation of the project site environment and power supply requirements, we customized a set of targeted cable solutions, focusing on solving the client’s pain points through our advantages of SAA certification, complete product range, and high quality. The core products selected for the project include three types of cables, each with specific specifications and unique advantages to meet different application scenarios.

The first is the Medium Voltage Cable, which is mainly used for high-voltage power transmission between the onshore power station and the port terminal. According to the project’s power demand, we selected the 8.7/15 kV XLPE insulated medium voltage cable, with conductor cross-sections of 120 mm², 150 mm², and 185 mm². This cable adopts cross-linked polyethylene (XLPE) insulation, which has excellent high-temperature resistance and insulation performance, and can stably transmit high-voltage power in the high-temperature and high-humidity environment of Tokelau. Compared with ordinary medium-voltage cables, our Medium Voltage Cable has a higher current-carrying capacity, which can meet the peak power demand of the port, and its insulation layer is specially treated to resist salt spray corrosion, avoiding insulation breakdown caused by marine environment erosion.

The second is the SWA Cable (Steel Wire Armored Cable), which is used for underground and outdoor power supply lines of the port terminal. We provided SWA cables with specifications of 4-core 50 mm², 4-core 70 mm², and 3+1 core 95 mm², which are armored with galvanized steel wire to enhance mechanical strength and anti-interference performance. In Tokelau’s port environment, where there are frequent mechanical operations and potential external impacts, the SWA Cable can effectively resist extrusion, impact, and rodent damage, ensuring the integrity of the cable structure. In addition, the steel wire armor layer can also play a role in anti-corrosion and moisture-proof, preventing the cable from being damaged by the humid marine air and underground water, which is far superior to ordinary unarmored cables in service life and stability.

The third is the Elastomer Cable, which is used for the connection of mobile power equipment in the Ship-to-Shore system, such as shore power connectors and mobile charging devices. We selected elastomer cables with specifications of 2-core 2.5 mm², 3-core 4 mm², and 4-core 6 mm². The cable uses high-quality elastomer insulation and sheath materials, which have excellent flexibility and wear resistance, and can be bent freely without breaking, adapting to the frequent movement and connection of mobile equipment. Compared with ordinary PVC cables, Elastomer Cable has better low-temperature resistance and aging resistance, and can maintain stable performance even in the large temperature difference environment of Tokelau’s day and night, and is not easy to crack or age after long-term use.

The most critical advantage of our solution is that all the above cables are saa approved cable. SAA certification is a strict safety certification issued by Standards Australia, which strictly tests the cable’s electrical performance, mechanical performance, and environmental adaptability, ensuring that the product meets the AS/NZS 5000 standard and is suitable for harsh environments such as marine and port areas. This is also the core reason why the client chose us—many other suppliers could not provide SAA-certified cables, and their products could not pass the local safety inspection, which would bring huge safety risks and project delays to the project.

3. SAA Certification and Strict Quality Control

For the Ship-to-Shore power system project, safety is the top priority. The port power supply involves high-voltage electricity and marine environments, and any cable failure may lead to power outages, equipment damage, or even safety accidents. Therefore, we have established a complete safety guarantee system, starting from product design, production, and testing to ensure that every cable delivered to the client meets the highest safety standards.

First of all, the saa approved cable is the core guarantee of safety. All our cables have passed the rigorous testing of SAI Global, including insulation resistance, withstand voltage performance, fire resistance, corrosion resistance, and other indicators, which fully meet the safety requirements of Tokelau’s port power supply and the relevant standards of the International Electrotechnical Commission (IEC). This means that our cables can stably operate in high temperature, high humidity, salt spray, and other harsh environments, without insulation aging, short circuit, or other safety hazards.

Secondly, we implement strict quality control in the production process. From the selection of raw materials, we use high-purity copper conductors and imported insulation materials to ensure the conductivity and insulation performance of the cables. During the production process, we adopt advanced production equipment and process control to ensure the uniformity of the cable structure, avoid problems such as uneven conductor stranding and insufficient insulation thickness. After the production is completed, each batch of cables will undergo 100% testing, including high-voltage withstand test, insulation test, and mechanical performance test, and only the products that pass all tests can be delivered to the client.

In addition, we also provide professional technical guidance for the client, including cable installation, laying, and maintenance suggestions. According to Tokelau’s marine climate and port environment, we suggest that the cables be laid in aluminum channels and UV-stabilized conduits to further enhance corrosion resistance and service life. Our technical team also communicates with the client’s construction team in a timely manner to solve any technical problems encountered during the installation process, ensuring the safe and smooth operation of the power system.

4. Overcoming Geographical Barriers to Ensure Project Progress

Tokelau’s remote geographical location and inconvenient transportation are important challenges for the project’s delivery. The port of Tokelau has no formal berthing facilities, and all equipment and materials need to be transported by barge, which is not only time-consuming but also has strict requirements on the size and weight of the goods. In response to this problem, we formulated a detailed delivery plan to ensure that the cables are delivered to the project site on time and in good condition.

First of all, we optimized the packaging of the cables. According to the specifications and weight of different cables, we used moisture-proof, anti-collision packaging materials to avoid damage to the cables during transportation. For large-volume SWA Cable and Medium Voltage Cable, we adopted coil packaging to reduce the volume and weight, making it easier to load and unload on the barge. Secondly, we cooperated with a professional international logistics company with rich experience in Pacific island transportation, formulated a reasonable transportation route, and avoided delays caused by weather and sea conditions. We also kept in close contact with the client and the logistics company to timely track the transportation progress and solve any problems encountered during the transportation process.

In addition, we also adjusted the production schedule according to the client’s project progress, ensuring that the cables are produced and tested in advance, and can be shipped immediately after the client’s demand is confirmed. We also prepared a small amount of spare cables and sent them together with the formal order to avoid the problem of project delay caused by cable damage or shortage during installation. Our professional after-sales team also arrived at the project site in advance to provide on-site guidance for cable installation and testing, ensuring that the installation work is carried out smoothly.
