Large submarine cable dredging floats play a key role in offshore pipeline and cable operations. These floats are essential to ensure buoyancy, stability and protection of underwater systems, especially in challenging marine environments. Submarine cable floats relieve the burden on cables and pipelines, preventing damage caused by environmental forces such as strong currents, seabed irregularities and waves. By keeping cables and flexible pipelines at the desired location and depth, these floats ensure the efficiency and safety of offshore facilities.

Cable floats have several key properties that make them an integral part of offshore applications. The buoyancy system can be adjusted to operate in seawater depths from surface to 6,000 metres and beyond.

• Polyurethane advantages

Polyurethane is commonly used in its manufacture due to its durability and resistance to harsh underwater conditions. This material ensures that the floats can withstand prolonged exposure to salt water, UV radiation and extreme temperatures without degradation. By reducing top tension loads, dredging floats relieve stress on cables and pipelines, minimizing the risk of fatigue and damage over time.

• Maintain location, easy installation

Whether used for oil and gas risers or power cable systems, these floats can be designed to the unique requirements of the project, with distributed buoyancy blocks ensuring proper alignment and buoyancy. Fast, efficient and safe offshore installation is another big benefit of pipeline floats. Their lightweight yet robust design allows for rapid deployment, reducing installation time and operating costs.

• Uplift 

Subsea offshore buoyancy ensures that cables and pipelines remain stable and properly positioned in the water column. This stability prevents movement that could cause wear, kinking or misalignment. They also help maintain position along flexible pipes or cables, providing consistent support over long distances. To ensure compatibility with a wide range of cable sizes, compatible clamping systems are used. These systems securely attach the floats to the cable or pipeline without causing damage, allowing for flexibility and easy adjustment during installation.

For specialized applications, manufacturers can customize dredge pumping float to meet the needs of specific projects. This includes customizing the size, buoyancy and clamping systems to suit specific operating conditions. Customization ensures optimal performance and extends the service life of cables and pipelines in demanding environments. Investing in high-quality custom dredging floats is essential to the long-term success of offshore pipeline solutions.
