Polyurethane submarine cable protection tube is a submarine cable protection system designed and developed to protect subsea: fiber optic cables, power cables, umbilicals, flexible flowlines, rigid flowlines, hoses and bundled products from abrasion and impact. Submarine cable protection system can also be used to add ballast to cables and flowlines and  reduce the risk of dropped object damage.

Subsea cable protection systems (CPS) features：

Shock-resistant polyurethane protective tube, a protector of communications and electricity cables, protects special pipes and sea floor cables for sea floor installation from shock and abrasion. Polyurethane submarine cable protection tube protects cable from shock derived from anchor, due to its excellent elasticity, corrosion-resistance, hydrolysis-resistance and insulation attributes. The durability of polyurethane submarine cable protection tube will last more than 25 years under the sea floor environment with outstanding abrasion-resistance, where cables and pipes cross.

The basic product unit is 1.0-2.0m and the installation working time in the sea floor can be reduced.

Characteristics of material : 

•Protect cable from shocks of anchors with urethane elasticity.

•Affinity to cable means no damage to the cable cover.

•No abrasion under any marine conditions such as ground or rock subsidence

•Excellent anti-corrosion in pipe corroding environment with submarine cables.

•Durability of longer than 25 years in submarine environment excellent resistance to hydrolysis.

•Workability : basic unit in 1.0m-2.0m means lighter weight and reduced work time.

•No need for barge crane or secondary work vessel when laying.

Design features: 

•The Submarine cable and pipeline protection is designed to be safe to handle and fast to install. 

•The design features overlapping and interlocking half shells to provide a close fitting protection around the pipeline, whilst also ensuring alignment during installation. Cable and flowline crossing protection can be manufactured from marine grade PU materials in lengths of up to 1-2 metres. 

•The Polyurethane submarine cable protection tube system is secured using either corrosion resistant alloy strapping, placed in recesses on the product during installation. These recesses ensure an even spacing of the strapping along the pipeline without measuring along with a smooth consistent outer diameter. 

•Cable and flowline protection system abrasion protection provides a cost-effective solution where cable entry to a platform is not possible via existing ‘J’ or ‘I’ tubes.

•Submarine cable protection duct can be configured to achieve neutral or positive buoyancy, allowing cables to cross subsea ravines, gorges, canyons, or trenches—rather than navigating around them—no matter the depth.

•Cable protection solution is crucial for ensuring the safety and longevity of subsea cables, pipelines, and other infrastructure in industries such as telecommunications, energy, oil and gas, and marine construction. Its ability to withstand harsh underwater conditions, coupled with its flexibility and ease of installation, makes guard cable & crossing impact protection system a must-have component for any subsea protection system.
