Designing for the deep-sea environment requires addressing extreme physical and environmental pressures:

: Short lines that transport hydrocarbons from individual subsea wellheads to a central collection point or platform.

: Connect different components of a subsea production system, such as wellheads to manifolds or platforms. Engineering and Design Challenges

: Large-diameter arteries that move processed fluids from offshore facilities to shore or other major hubs.

Offshore pipelines are generally categorized by their role in the production and transport cycle:
