This section discusses the various production systems that industry will use to produce oil and gas from deep water reservoirs. The primary purpose of this section is to describe these systems and associated activities. We will then use these descriptions to assess the physical impacts of the installation and operation for each type of system. These production systems include sub seawells, fixed platforms, compliant towers, spars, tension leg platforms, and floating production, storage and offloading systems (FPSO's). For this paper, deepwater means leases located in water depths greater than 1,000 ft
