We are pleased to announce that our company has successfully signed a comprehensive contract for the supply of submarine cable accessories with a Vietnamese customer for an offshore wind power project. This contract marks a significant milestone in our continued expansion into the Southeast Asian renewable energy market, reinforcing our position as a trusted provider of high-performance subsea cable protection systems.
Project background
With the growing demand for clean energy, offshore wind power projects in Vietnam have gained momentum in recent years. Our client, a key player in Vietnam’s offshore wind development sector, required a full suite of cable management accessories to ensure the safe and reliable installation of submarine power cables. The scope of the project includes the installation of 3-core submarine cables in varying sizes—3x300mm², 3x185mm², and 3x95mm²—requiring tailored protection solutions.
Products supplied
Under this contract, we will supply the following submarine cable accessories, all designed and manufactured in China with high-performance polyurethane and marine-grade materials:
• Centralizers:
Centralizer for 3x300mm² submarine cable
Centralizer for 3x185mm² submarine cable
Centralizer for 3x95mm² submarine cable
These J-tube centralizers play a crucial role in aligning and stabilizing submarine cables as they are pulled through the J-tube system. By keeping the cable centered within the tube, the centralizers prevent abrasion, reduce mechanical stress, and ensure smooth installation.
• Bend restrictors:
Bending restrictor for 3x300mm² submarine cable
Bending restrictor for 3x185mm² submarine cable
Bending restrictor for 3x95mm² submarine cable
Our polyurethane bend restrictors are engineered to prevent overbending and fatigue damage at critical transition zones such as the seabed touchdown point or J-tube exit. These restrictors are manufactured using high-quality casting processes, ensuring excellent corrosion resistance, impact strength, and a service life exceeding 25 years—ideal for long-term offshore deployments.
• Hang-off:
Hang-off for 3x300mm² submarine cable
Hang-off for 3x185mm² submarine cable
Hang-off for 3x95mm² submarine cable
The hang-off system secures the cable at the top of the J-tube or entry point on the offshore platform. Designed to accommodate cable weight and dynamic loads, the hang-off provides mechanical support and sealing, ensuring a stable and watertight connection during and after cable pull-in.
Why choose us
As a leading manufacturer of submarine cable accessories in China, we specialize in delivering custom-engineered solutions tailored to the cable diameter, bending radius, and operational load of each project. Our products are widely used in offshore wind farms, oil & gas platforms, and subsea interconnect projects across Asia, Europe, and beyond.
With in-house polyurethane molding, precision machining, and rigorous quality control, we ensure that every component meets the highest international standards for offshore applications. Our ability to quickly adapt and customize based on client specifications has been key to winning the trust of partners in emerging renewable energy markets such as Vietnam.
Looking ahead
This Vietnam project not only strengthens our presence in the Asia-Pacific offshore wind industry but also reflects the growing confidence in Chinese-made subsea cable protection products. We look forward to supporting more regional wind projects with our reliable solutions and technical expertise.
