Semi-submersible rigs have “legs” that are variable-buoyancy chambers that can be flooded or evacuated to keep the surface of the platform level and stable in unstable seas. Thousands of new, high-quality pictures added every day. Not suitable for ice. RIG CONCEPT & DESIGN ( RCD ) ... Semi-Submersibles, Drillships), offshore platforms, land rigs, equipment, yachts, where the user can freely explore and interact with a 3D model of a conceptual or finished project. When oil fields were first developed in offshore locations, drilling semi-submersibles were converted for use as combined drilling and production platforms. The same rig also set the record for subsea completions in 7,571 ft in the GOM as the deepest producer. 5. 2. Land rig on barge (with optional submerged caissons), 3. Environmental Impact low. A semi-submersible structure is adapted to carry consumable solid or liquid material such as mud, and removable equipment, for example drilling tubulars. Semi-Submersible is one of the drilling rig design concepts for offshore shallow water environments. WGMN was responsible for the basic design and participated in the detailed design of the semi-submersible hull and main marine systems. Swamp Barge (With Optional Submerged Caissons), 9. The designs of many of the modern generation of floatels are derived from semi-submersible designs intended for drilling operations in deep water and moderate environments, where dynamic positioning (rather than mooring) and a high variable load capacity are prominent design requirements. Modularised and Pile Elevated Drilling Rig, 10. One of the largest ultra-deepwater 6th generation semi-submersible rigs capable of working in harsh-environment conditions, the Moss Maritime CS50 MK II design ultra-deepwater dynamic positioning (DP3) semi-submersible unit is designed for versatility and flexibility.
