Subsea acoustic insulation is used to mitigate noise associated with any one or a combination of a deep-water production tree, a deep-water manifold or structure, subsea pumping equipment, or subsea compression equipment. A subsea oil and gas facility includes subsea equipment having one or more devices that generate noise during operation, and subsea acoustic insulation surrounds at least a portion of the subsea equipment and is configured to attenuate the generated noise.
