Floating production systems
Shell has demonstrated drone-in-a-box operations from its Mars floating production unit, becoming the first operator in the region to secure FAA approval for self-approved offshore beyond-visual-line-of-sight flights. JPT Senior Technology Editor Jennifer Pallanich visited Shell Technology Center Houston to see the system in action.
This paper explores the application of a modular, high-temperature gas-cooled nuclear reactor to a Very Large Crude Carrier-class floating production, storage, and offloading vessel.
After launching pre-salt production in Brazil, the ultradeepwater Tupi asset has become one of Petrobras’s most productive.

This paper describes the CLOV deepwater megaproject in Block 17 offshore Angola, which cost USD 8.4 billion to first oil. -
Historically, the marine systems on a spar are relatively simple.
-
Construction costs, contractor involvement, flow assurance, and the integration of new technologies created to improve production are some of the deepwater challenges exacerbated by the current low price environment.
-
As many platforms begin to produce beyond their design life, maintenance of mooring systems becomes more critical. With redundancies in place, operators may be unaware of initial failures, which can have major consequences if another failure occurs.
-
A routine maintenance project became more complicated when an ROV inspection exposed unexpected trenching that reduced the holding capacity of the system.

Though the projects that have already been sanctioned will ensure that spending in the FPS sector will remain high over the forecast period, the growth in FPS market is significantly less than expected due to the collapse in oil prices, and installations in 2018 will decline.

A deepwater field located offshore Sabah, east Malaysia, features a spar dry-tree unit (DTU) and multiple subsea-hub tiebacks to a floating production, storage, and offloading vessel (FPSO).

After 10 years, the world’s first cell spar, Anadarko’s Red Hawk, was decommissioned. It remained the only cell spar fabricated and again made history as the deepest floating production unit ever decommissioned in the GOM.
-
For Anadarko, the secret of the “design one, build many” approach to offshore production facilities is to control its enthusiasm for change. The company’s experience with eight operated spars shows the benefits gained with this approach.

A new type of organically modified silica glass that can remove a wide variety of oils and contaminants from produced and flowback water is showing promising results as it undergoes field trials.
