Key points
- Noise above NOAA-designated thresholds for marine mammal impact will be limited to within several kilometers of the production vessel, similar to other marine industries.
- Two light sources are involved: the surface vessel, lit at night for 24-hour operations, and the seabed collector vehicle operating at 4,000 meters depth.
- The collector vehicle carries two large spotlights on its front, creating a pool of light spreading 20 to 30 meters around it, likened to two-car headlights.
- Ocean-going birds can be attracted to the vessel’s deck lighting at night and may interact with infrastructure, an issue common to vessels operating on the high seas.
