1. Regional Challenge Analysis
The Mediterranean Sea, particularly offshore Italy and the Strait of Sicily, is renowned for its complex currents and rugged seabed topography. Deploying subsea assets in such environments requires addressing several critical pain points:
High-Current Fatigue: Continuous water flow can trigger Vortex-Induced Vibration (VIV) in pipelines, significantly shortening cable lifespan.
Rocky Seabed Abrasion: In areas where trenching is impossible, cables are directly exposed to hard rock, making them highly susceptible to physical damage.
Extreme Mechanical Loads: During deep-sea installation and dynamic operation, cables face the risk of snapping if they exceed their Minimum Bend Radius (MBR).
2. Our Hybrid Engineering Solution
To meet these challenges, Philson has introduced a hybrid protection scheme combining High-Performance Polyurethane (PU) with Super Duplex Stainless Steel, achieving a perfect balance between structural strength and flexibility:
A. Advanced MDI Polyurethane Outer Shell
Corrosion Resistance: Utilizing MDI polyurethane optimized for high-salinity environments ensures physical stability remains intact even after 25 years of subsea service.
Neutral Buoyancy & Cushioning: By controlling material density between 1.10 - 1.17 g/cm³ (close to seawater), our solution provides a physical wear layer without adding extra static gravity loads to the cable.
B. Stainless Steel Structural Reinforcement
Integrated Stainless Steel Framework: For modules subjected to extreme lateral tension, we embed 316L or Super Duplex Stainless Steel skeletons. This "bone" structure ensures the protection device maintains its geometry and MBR restriction functions even under intense current impact.
Premium Fastening System: All connectors utilize Super Duplex 2507 stainless steel, completely eliminating electrochemical corrosion risks and ensuring the long-term integrity of the system structure.
3. Comprehensive Protection Categories
Philson’s Cable Protection Systems (CPS) cover every critical node from the seafloor to the platform:
Bend Restrictors: Utilizing a mechanical lock-out mechanism to enforce MBR limits in high-current zones, protecting cables from over-bending damage.
Bend Stiffeners: Providing a smooth stress transition to prevent stress concentration and fractures where cables connect to fixed structures like J-tubes.
Distributed Buoyancy Modules (DBM): Creating a stable wave profile for subsea cables through precision buoyancy distribution, reducing friction pressure against the seabed.
4. Efficiency & Maintenance
Split-unit Design: Our modular design allows for rapid installation without cutting the cable, significantly shortening vessel time and lowering offshore construction costs.
25-Year Maintenance-Free Promise: Thanks to the chemical stability of our hybrid materials, the products require virtually no maintenance after installation, greatly reducing long-term Operating Expenditure (OPEX).
