Submarine Polyurethane Riser Clamp

In deep-sea oil and gas extraction, wind power transmission and other submarine projects, the riser system is a key fluid and energy transportation channel. In order to ensure the safe and stable operation of these pipelines in the complex and changeable submarine environment, the submarine polyurethane riser clamp came into being and became an indispensable component of the riser system.

1. The main function of the submarine riser clamp

The submarine riser clamp is a device used to fix, support and protect the submarine riser. It is mainly installed in structures such as J-tubes, conductor racks, floating platforms, etc., and has the following functions:

Positioning and fixing: Prevent the riser from displacement, twisting or falling off due to external forces such as ocean currents, waves, and platform movement;

Protect the outer wall of the riser: Reduce direct contact with the metal structure to avoid wear or corrosion;

Buffering and shock absorption: Absorb dynamic loads from waves, platform shaking, etc., and reduce fatigue damage to the riser;

Improve system life: Through long-term stable support and protection, the service life of the submarine riser is effectively extended;

Easy to install and maintain: Some clamps are designed with modular structures for easy construction, inspection and replacement.

2. Performance advantages of polyurethane materials

Polyurethane (PU) is a high-molecular synthetic material with excellent performance, especially suitable for use in marine environments. The polyurethane material used for riser clamps has the following outstanding features:

Excellent wear resistance: can withstand long-term friction and scouring, especially suitable for environments such as seabed sand flows;

High elasticity and strong buffering: can maintain deformation and recover quickly under high loads, providing reliable buffering support;

Resistant to seawater and chemical corrosion: not easily corroded by seawater, oil and gas and various chemical substances, suitable for long-term underwater work;

Low water absorption rate: maintain structural stability and avoid the material from swelling due to water absorption and affecting its function;

Good molding and processing: can be customized according to different riser diameters and clamping forms to meet the diverse needs of the project;

Long service life: strong weather resistance, can still work stably for a long time under extreme temperatures and pressures.

3. Application fields

Submarine polyurethane riser clamps are widely used in the following marine engineering fields:

Submarine oil and gas pipeline support system

Offshore wind power cable protection and positioning

Deepwater floating platform (such as FPSO, SPAR) riser fixture

Submarine optical cable or signal pipeline management system

Riser concentrator device in J tube or I tube

In deep-sea environment, safety and stability are the core of pipeline system operation. The selection of high-performance polyurethane cable hang-off clamps can not only effectively protect key facilities, but also help improve the reliability and operation efficiency of the overall system.
