Protection of Subsea Pipelines and Cables After Installation
Subsea pipelines and cables—including oil and gas pipelines, as well as power and communication cables—serve as the “major arteries” of energy transmission and information connectivity. Once laid on the seabed, they frequently encounter complex and severe environmental challenges. Consequently, protection engineering is a critical component for ensuring their long-term safe and stable operation, with core objectives being to prevent mechanical damage, mitigate environmental hazards, and maintain structural integrity.
