Products classified under HTS 8430.49.40.00
Deepwater Horizon Semi-Submersible Drilling Platform
A semi-submersible offshore platform designed for deepwater oil drilling operations, equipped with drilling rigs, mud systems, and living quarters. It falls under HTS 8430.49.40.00 as specialized boring machinery for extracting oil from seabed reservoirs in offshore environments. These platforms are self-propelled or towed and rated for water depths exceeding 1,000 meters.
Spar Type Floating Production Platform
A cylindrical spar platform used for offshore oil and gas production, featuring topsides with processing facilities moored in deep water. Classified under HTS 8430.49.40.00 for its role in boring and extracting hydrocarbons from subsea wells. It provides stable production storage and offloading capabilities.
Jack-Up Drilling Rig Platform
A mobile offshore drilling unit with extendable legs that elevate the hull above sea level for shallow water oil exploration. It qualifies under HTS 8430.49.40.00 as boring machinery specifically engineered for offshore natural gas and oil drilling. Typically used in water depths up to 400 feet.
FPSO Converted Drilling Platform
A Floating Production Storage and Offloading (FPSO) vessel converted for offshore drilling and production with turret mooring and subsea well intervention capabilities. Falls under HTS 8430.49.40.00 due to its integrated boring and extraction systems for oil fields. Capable of processing 200,000 barrels per day.
Tension Leg Platform (TLP) for Gas Production
A Tension Leg Platform secured by vertical tendons to the seabed, used for dry natural gas production in ultra-deepwater fields. Classified in HTS 8430.49.40.00 as offshore boring and production machinery for hydrocarbons. Offers minimal vertical motion for precise drilling.
Submersible Oil Production Platform
A bottom-supported submersible platform that can be submerged for transport and raised for operation in offshore oil fields. It is included under HTS 8430.49.40.00 for its specialized design in boring and producing oil from marine minerals. Suitable for moderate water depths with high stability.
Drillship Offshore Platform
A self-propelled drillship platform with dynamic positioning systems for ultra-deepwater oil drilling worldwide. Falls under HTS 8430.49.40.00 as advanced boring machinery for offshore petroleum extraction. Equipped with heave-compensated derricks for 12,000-foot water depths.
Fixed-Leg Production Platform
A fixed-leg jacket platform with piled foundations for long-term offshore natural gas production. Classified under HTS 8430.49.40.00 for its boring wells and production topsides in shallow to mid-depth waters. Designed for 20-30 year field life.
Compliant Tower Drilling Platform
