Marine infrastructure includes the platforms, subsea structures, pipelines, and cables crucial to our offshore activities in oil and gas, energy, and telecom. Largely hidden beneath the waves, marine infrastructure is critical to the effective operation of our offshore energy and communication systems. These are the platforms, subsea structures, pipelines, moorings, and power and telecom cables that underpin our offshore activities in oil and gas, wind, wave and tidal energy, and global telecommunications. The design of subsea cables and pipelines can present unique challenges, which are often times in conflict with one another, necessitating a delicate balance be struck between issues like water depth and calculated risk factors.
