Report on Leg Reaction of a K-Type Mast
Single-lift rig, double-lift rig
Travelling block reeving can be implemented through the sequent wire pulling method or cross wire pulling method. The choke control box is opposite the driller's control cabin of the rotary table.
The operating wind speed is a 3-second gust speed of 28.1 m/s with a 5-year recurrence interval. Verify the speed of expected and unexpected storms.
Casing stabbing boards replaced with hydraulic baskets; rotary catheads and hydraulic catheads used; dynamic braking allowing drilling tools to be hanged and stopped; automatic heave compensating drawworks equipped with string stabilizers; a fully intelligent driller's operation chair with an intercom system
Stresses at the contact surfaces of pinions and racks of the jacking system do not change. There is a lateral force on leg chords. The jetting line of a spudcan connects with a mud pump.
The conductor tension platform located under the wellhead area of the cantilever beam replaces the wellhead deck of the jacket in well drilling operation.
A trip tank and a striping tank are integrated into a floating level meter. The overall pressure applied to the mud pit tank is positive. The mud pit tank is equipped with a scraper, a cuttings drier and a conveyor. A buffer tank is added between a bulk tank and a filling station.
MEP placement on the deck and offshore cementing when the whole support vessel is moving
Process and layout designs for the utility lines such as the oil, water, air and power lines on the MEP module
The discrete central control system consists of logic switches, public broadcasting systems, cabin depth sensors, remote-controlled valves, and incinerators.
The floating body of the support vessel accommodates winches, rheostatic braking tanks, air supply pressure reducing stations, bulk control breadboards, and jockey pumps for fire protection.
A crane with amplitude-variable steel wires is used to move LWD containers.
