Subsea Systems in Oil and Gas - The Underwater World

Explore how risk is computed as likelihood times consequence, and compare qualitative and quantitative methods to inform cost-benefit decisions for subsea field architecture and components.

Explore how a floating production, storage, and offloading vessel acts as a self-contained offshore production facility that receives, processes, stores crude, and offloads to shuttle tankers.

Explore how the subsea wellhead provides pressure containment and a production interface, directing hydrocarbons from the reservoir to the Christmas tree with structural support and access for intervention.

Explore the subsea christmas tree, the seabed control center that directs well flow and safety, comparing vertical and horizontal designs and their valve placement.

Explore the $5 million bottleneck of subsea X-tree delivery, its 18–22 month timeline, and how the IOGP S561 standardization aims to cut delays and accelerate to production within 24 months.

Explore how subsea pipelines are engineered to survive the deep, from concept to abandonment. Understand protective design against functional, environmental, and accidental loads under the DNV OS-F101 standard.

Compare carbon steel traditional pipelines with flexible pipelines, highlighting the absence of welds, no internal corrosion inspection required, easier installation, seabed adaptability, reduced maintenance, and easier future tie-ins.

Connect the pipeline to subsea structures through the pipeline end termination, enabling jumper links, metrology for jumper length, and isolation valves with injection and venting ports for flow assurance.

Operate pig launchers and receivers (PLR) to deploy and recover pigs, enabling dewatering, cleaning, and internal inspection for pipeline integrity.

Explore manifold installation in subsea systems through an animation, and discover the underwater world of oil and gas.

Explore manifold fabrication for subsea oil and gas systems, gaining practical insight into designing, fabricating, and integrating subsea manifolds in the underwater environment.

Discover how subsea manifolds collect, control, and protect multiwell flows in the deep sea, and compare modern cluster versus template designs, including suction piles and mud mats under ISO 1368.

Explore the pipeline end manifold (plem) as the final subsea node that terminates pipelines, isolates subsystems, connects export lines and risers, and integrates with the subsea production system.

Connect subsea equipment to the surface facility with risers that transport fluids from the seabed to the surface, enabling rigid and flexible configurations for floating and deepwater developments.

Watch an animation that demonstrates risers installation in subsea systems, providing a clear overview of underwater installation processes for oil and gas infrastructure.

Learn how the subsea industry shifts from engineer-to-order to configurable-to-order, using modular, standard building blocks to speed delivery and reduce costs.

Umbilicals form the lifeline of subsea control, bundling electrical, hydraulic, and chemical lines to power, control signals, and injections from surface facilities to the seabed production system.

Explore subsea systems in oil and gas and the underwater world, focusing on umbilical armoring and its role in protecting critical offshore equipment.

Explore umbilical loadout within subsea systems in oil and gas, outlining how equipment is organized to support subsea operations.

Connects and terminates the underwater umbilical, housing electrical, hydraulic, and chemical cores in a single interface to the subsea tree or manifold, enabling reliable underwater termination and core connections.
