Semi Submersible Rig. The vessel was a selfpropelled large semisubmersible design with a drilling facility and living quarters It was capable of operation beneath 1500 feet (460 m) of ocean water and could drill to a maximum depth of 25000 feet (7600 m) It was described by ODECO as the world’s largest semisubmersible oil rig to date Constructed for ODECO in 1976 by Mitsubishi Heavy.

A submersible drilling rig is a marine vessel design that can be floated to location and lowered onto the sea floor for offshore drilling activities Design and operation The submersible drilling platform is supported on large pontoonlike structures These pontoons provide buoyancy allowing the unit to be towed from location to location Once on the location the pontoon.

Fig 04 SemiSubmersible Rigs A second type of floating vessel used in offshore drilling is the drillship Drillships are designed with the rig equipment and anchoring system mounted on the central turret The ship is rotated about the central turret using thrusters so that the ship always faces incoming waves This helps to dampen wave motion Fig 5 Drill Ship.

Semisubmersibles are the choice for drilling from a floating position due to the deep water depths Semisubmersible (“semi”) rigs float like a ship while being towed into position where their pontoons can then be flooded partially submerging the rig Figure 54 illustrates a typical semisubmersible Because the main part of the.
