Deep water oil fields present unique challenges due to their increased complexity in equipment layouts and installation engineering. This content explores the intricate systems used in modern deep water oil extraction, where subsea production systems can vary from a single wellhead linked to a platform or onshore facility to multiple wells clustered around manifolds connected to production platforms. This setup enhances profitability by allowing one platform to service multiple well sites. The discussion includes a detailed overview of the components involved, such as wellheads, manifolds, pipelines, and termination structures (PLETs), all of which are critical for the efficient flow of oil from the seabed to processing facilities. The complexities of these systems require advanced installation engineering, incorporating considerations like pipeline weight, size, coating, thermal insulation, and even electrical heating. Understanding these factors is essential for the successful development and operation of deep water oil fields.
