Of course, the mini-ROVs can also be used for any onboard water and/or cooling tanks. In 1947, the first platform “out of sight of the land” was built off the coast of Louisiana in 20 ft of water. On a jacket platform, the working platform is generally sitting above the water line and the risers are lowered into the ground. These platforms are a larger version of semi-submersible design. It’s a hub for three fields - Great White, Tobago and Silvertip - in the Gulf of Mexico. Floating piers and docks 3. Advertisement. Floatable/bottom-founded concrete-hull structures 2. Again, mini-ROVs are perfect for inspecting the underwater infrastructure of these structures as well as any onboard water and cooling tanks. Depending on the requirements, an oil platform may be floating or fixed to the ocean floor. The … Fixed structures owe their name to the fact that they rest on the seabed, and are fixed to a specific point. The most common concrete designs are: Condeep (with one, two, three or four columns) This document outlines the procedure for upgrading the firmware on BRIDGE products. Types of Offshore Platform Decommissioning: Complete removal – removal of all infrastructure above and below the seabed. It also has a “moon pool” in the center of the structure that is used to allow the drill string the extent through the hull of the ship and down to the drill site. Offshore production platforms are structures used to drill and service wells on the ocean floor. Improve design for operational safety through ship impact and dropped object analysis, and minimize risk through offshore-specific load generation. Fixed platforms are built on large steel or concrete legs that are fitted directly onto the seabed. One of the beauties of my job is the fact that I get to learn so much about the different industries that we work in. They boast space for drilling rigs and production facilities, as well offer accommodation facilities for crew. But instead of anchors, they are connected to the ocean bed by flexible steel legs. With floating hulls and tension legs used to hold them in place, they are generally used in smaller deep-water reservoirs when it is not economically efficient to build a larger structure. An offshore platform deals with topside facilities as well as the underlying drilling facilities. HMC manages the entire supply chain of offshore construction, from design through to completion. With the use of the ship’s computer system (which uses satellite) technology, the propellers are constantly working to hold the ship directly above the drill site at all times. HMC excels at transporting, installing and removing offshore facilities. Ensure compliance with comprehensive offshore design code coverage in SACS Offshore Structure. They are equipped with underside electric motors that are capable of propelling the ship in any direction. They may have compressors and some treatment equipment like separators, and often have equipment for use in workovers. The module assemblies then are barged offshore, lifted onto the platform, and hooked up. On these structures ROVs such as the DTX2 can be used to inspect the underwater infrastructure when the structure is not too deep. Drillships use “dynamic positioning systems” to ensure that the ship is directly above the drill sites at all times. Ok last time I already explained about the introduction of the offshore structures and now we move to the main contents, types of offshore structures. More Offshore Production Platforms. “IRM” Offers a wide range of Marine and Boat Fenders to suit almost all types of berthing applications in various Climatic and Onsite conditions. The upper hull contains the living and working areas for the crew while the lower hull works to make the structure buoyant. This platforms are meant for deep sea drilling. Drillships are marine ships fitted with drilling equipment and the dynamic positioning system, which maintains their positions over oil well. An oil rig is a manned platform used for land or off-shore drilling. Improve design quality and predict offshore structural performance using a unified analysis environment … Even though mini ROVs are not used as often as work class ROVs in the offshore energy industry, mini ROVs still play a vital role in on-going inspections and maintenance. Perdido The deepest spar type oil platform in the world, the Perdido, is moored in 2,450 metres (8,000 feet) of water and produces oil and gas from depths of between 2,300-2,800 metres (7,500-9,500 feet). They are flexible in design to sway and move laterally with the forces of wind and waves. This actually allows the working platform to sit above the water as opposed to a floating barge. ), the environmental conditions in the platform’s location and the load’s location in relation to the crane. In addition to all of the normal ship components, a drillship will typically have a drilling platform and derrick (the tall structure used as part of the rig hoisting system) placed in the middle of its deck. An oil platform, offshore platform, or offshore drilling rig is a large structure with facilities for well drilling to explore, extract, store, and process petroleum and natural gas that lies in rock formations beneath the seabed. The pontoons sink below the surface of the water so the rig is partially submerged but still floats above the drill site. Home > Deep-draft concrete floaters (DDCFs) 3. What differentiates these structures are that once they are towed to the correct drilling site, three or four “legs” are lowered until they rest on the bottom floor. Whether you seek comprehensive data integrity, reduced storage costs, or to minimize disruptions to daily business processes, migration can be one way to achieve your goals.
