Northern Mariana Islands Fishery Expansion Project

In 2024, a large-scale fishery expansion and renovation project was launched on Santiago Island, Northern Mariana Islands. As a key part of the local marine economy upgrading plan, the project aimed to expand the existing fishery breeding area, upgrade intelligent monitoring equipment, and renovate the power supply system to improve breeding efficiency and sustainability. However, the harsh marine environment, strict local electrical safety standards, and the need for stable signal transmission posed significant challenges to the selection of electrical cables. Dongguan GERITEL Electrical Co., Ltd., with its high-quality products, complete SAA certification, and comprehensive product range, successfully provided customized cable solutions for this project, helping the client overcome key pain points and ensuring the smooth progress of the fishery expansion and renovation.

1. Challenges of Fishery Expansion in a Harsh Marine Environment

The Santiago Island fishery project is a key infrastructure project in the Northern Mariana Islands, covering an expansion area of 5,000 square meters and involving the renovation of 3 existing breeding workshops and the addition of 20 intelligent breeding ponds. The client, a local leading aquaculture enterprise, hoped that through this project, they could realize automated monitoring of water quality, temperature, and oxygen levels, and optimize the power supply system to ensure the stable operation of breeding equipment 24 hours a day. However, the project faced three core pain points that were difficult to solve.

First, the marine environment on Santiago Island is harsh, with high humidity, strong salt spray corrosion, and frequent typhoon weather. The cables used in the project needed to have excellent corrosion resistance, waterproof performance, and wind resistance to avoid cable damage caused by long-term exposure to saltwater and harsh weather. Second, the Northern Mariana Islands implements strict electrical safety standards, requiring all imported electrical products to have international authoritative certifications, and SAA certification is a necessary condition for entering the local market. The client had previously encountered problems such as delayed project progress due to unqualified cable certifications. Third, the project involved both power transmission and precision signal transmission. The cables needed to have stable electrical performance, strong anti-interference ability, and clear signal transmission to ensure the normal operation of intelligent monitoring equipment and avoid economic losses caused by signal distortion or power failure.

After comparing multiple suppliers, the client finally chose our company because of our complete product range, SAA-certified high-quality products, and rich experience in overseas fishery projects. They hoped that we could provide one-stop cable solutions that meet local standards and adapt to the marine environment, and ensure fast delivery to avoid delaying the project schedule.

2. Matching Cable Types to Project Needs

After in-depth communication with the client and on-site investigation of the project environment, our professional technical team tailored a set of cable solutions for the Santiago Island fishery project, focusing on three core cable types: Neutral Screen Cable, Elastomer Cable, and Instrumentation Cable. Each type of cable was selected based on the specific needs of different project links, and their unique advantages made them the best choice for the project.

2.1 Neutral Screen Cable: Stable Power Transmission in Corrosive Environments

The fishery’s power supply system requires stable and safe power transmission, especially in the marine environment where corrosion and electromagnetic interference are common. We recommendedNeutral Screen Cable with specifications of 3x10mm², 3x16mm², and 4x10mm², which are all SAA-certified. Compared with ordinary power cables, Neutral Screen Cable has a special copper wire neutral screen layer, which can effectively isolate electromagnetic interference and prevent power leakage, ensuring the stability of the power supply system for breeding equipment such as aerators and water pumps.

The cable uses PVC insulation and sheath materials that meet AS/NZS 4961 standards, which have excellent salt spray corrosion resistance and waterproof performance, and can withstand the harsh marine environment of Santiago Island. Unlike ordinary cables that are prone to insulation aging and sheath cracking in saltwater environments, our Neutral Screen Cable can maintain stable performance for a long time, reducing the frequency of cable replacement and maintenance costs for the client.

2.2 Elastomer Cable: Flexible and Durable for Complex Laying Scenarios

The fishery expansion project involves cable laying in narrow spaces such as breeding workshops and underwater pipelines, which requires cables to have good flexibility and mechanical strength. We provided Elastomer Cable with specifications of 2x2.5mm² and 3x4mm², which is made of high-quality elastomer insulation and sheath materials. Compared with traditional PVC cables, Elastomer Cable has better flexibility, can be bent at will without breaking, and is easy to lay in complex and narrow spaces.

In addition, the Elastomer Cable has excellent high and low temperature resistance, which can adapt to the large temperature difference between day and night on Santiago Island (ranging from 18℃ to 32℃) and the high temperature environment near the breeding equipment. It also has strong wear resistance and impact resistance, which can avoid cable damage caused by collisions during construction and daily operation. This flexibility and durability make it the ideal choice for cable laying in fishery workshops and underwater scenarios.

2.3 Instrumentation Cable: High-Precision Signal Transmission for Intelligent Monitoring

The intelligent monitoring system of the fishery requires high-precision transmission of weak signals such as water quality, temperature, and oxygen level data. We selected Instrumentation Cable with specifications of 2x0.75mm² and 4x1.0mm², which is specially designed for precision signal transmission. Compared with control cables, Instrumentation Cable adopts a multi-layer shielding structure (each pair of cores has an independent shield and the whole cable has a total shield), which can effectively resist external electromagnetic interference and ensure the high fidelity and low loss of signal transmission.

The Instrumentation Cable uses polyethylene insulation materials with low dielectric constant, which can reduce signal attenuation and ensure that the monitoring data is transmitted to the control center accurately and in real time. This avoids measurement distortion caused by signal interference, which is crucial for the client to adjust breeding conditions in a timely manner and ensure the survival rate of aquatic products. In contrast, using ordinary control cables to replace Instrumentation Cable would lead to serious signal interference, resulting in inaccurate monitoring data and potential economic losses.

As a professional cable factory, we not only provide standard cables but also customize cable specifications according to the specific needs of the project. For this fishery project, we adjusted the length of each cable according to the laying distance of different areas, avoiding waste and reducing the client’s procurement costs.

3. SAA Certification and Strict Quality Control

The Northern Mariana Islands has strict requirements on the safety of electrical products, and SAA certification is the core threshold for entering the local market. All three types of cables provided by our company have obtained SAA certification, which means that their design, materials, and production processes all meet the strict standards of the Australian and New Zealand electrical safety standards (AS/NZS), ensuring the safety and reliability of the cables in the project.

In addition to SAA certification, our company has established a strict quality control system from raw material procurement to production and delivery. We select high-quality copper conductors, insulation, and sheath materials to ensure the electrical performance and service life of the cables. During the production process, we conduct multiple inspections, including conductor resistance testing, insulation resistance testing, and shielding effectiveness testing, to ensure that each roll of cable meets the quality standards. Before delivery, we also conduct a comprehensive inspection of the cables to avoid unqualified products from being sent to the project site. This strict quality control system has won the trust of the client and laid a solid foundation for the smooth progress of the project.
