TSC Offshore's rotary table series are a step forward in reliability and serviceability. For convenience, the rotary table has the same physical envelope dimensions as existing rotary tables to facilitate swap outs. But this is where the similarity ends.
The table structure has been designed to provide maximum strength to ensure that the bearings and gears remain properly aligned regardless of the loads. The upper and lower labyrinth seals have been designed to provide optimal sealing characteristics while retaining a simple field replaceable geometry. The table assembly has been greatly simplified so it essentially drops into the housing for easier maintenance.
Our rotary table combines the benefits of conventional table design with efficient innovative approach that reduces downtime.
Designed in accordance with applicable API standards.
Two selective, unidirectional, independent ratchet type table locks.
Integrated forged/fabricated housing and table for a rigid, durable design to insure maximum durability.
Case hardened spiral bevel gear set.
Cartridge style pinion arrangement.
Double labyrinth style sealing for optimal mud / oil isolation.
TSC Offshore offers the following sizes of rotary table: 17½", 27½", 37½", 49½" and 60½".
Solids Control System
TSC Offshore manufactures a complete line of solids control equipment and complete mud tank system. TSC Offshore's solids control equipment includes: linear and elliptical shale shakers, centrifugal and shearing pumps, desanders, desilters, degassers, liquid gas separators, mud cleaners and mud hoppers.
The design of TSC Offshore's Shale Shaker was derived from observation and operation of similar field tested products. It contains three of TSC Offshore's own patents, including two types of products: the linear and the flat elliptical. The shaker features: high vibration intensity; large screen surface area; adjustable discharge angle during drilling; simple compact structure; reliable, great performance at a competitive price.
TSC Offshore offers a broad range of centrifugal pumps with high performance features like: heavy-walled construction and wide vane impellers for enhanced slurry handling capability. Heavy duty ball bearings in the power end provide the load carrying capability to operate under the high loads generated by weighted drilling muds and stimulation fluids.
TSC Offshore's centrifugal pump designs have proved to be among the best for handling abrasive cements and drilling fluids. They are available in wear-resistant materials compatible with the diverse applications of the oil and gas industry. TSC Offshore's centrifugal pumps are available from a few gallons per minute to over two thousands five hundred gallons per minute. When downtime is critical, it is good to know that the TSC Offshore's centrifugal pump is dimensionally interchangeable with most centrifugal mud pumps in service today.
TSC Offshore's centrifugal pump concentric casing design with equal distance from the tip of the impeller at all points allows for a much smooth flow path even at the shutoff conditions compared to volute style casing designs. This design minimizes turbulence often encountered at the cutwater where the fluid is pushed toward the discharge. The concentric casing design also greatly reduces bearing side loading due to unbalanced forces produced in volute style designs.
TSC Offshore's centrifugal pump also incorporates a full open impeller design which maximizes flow through the impeller reducing the axial load to the bearings. The entry curvature of the impeller vanes also helps the fluid to make a smoother transition into the casing of the pump. This smooth flow transition is essential when abrasive fluids and weighted drilling muds.
TSC Offshore provides bare pumps for customers who want to configure their own package designs and we also package horizontal in-line pump and motor systems connected by a coupling with OSHA full cover coupling guard and popular motor mounted over pump configurations for tight footprint requirements. Purchase a TSC centrifugal pump and discover as many already have why TSC Offshore is becoming a favored supplier for many critical rig components. With the assistance of our global distribution partners TSC Offshore is prepared to deliver your drilling product requirements when and where you need them.
The Cyclone Mud Mixer is used to efficiently mix treating fluid with the mud. It features good mixing capability, fast feeding and is not easily jammed. The pressure is very high when the mud comes out and the mud cannot escape up the funnel. The jet mixer has good mixing capability and feed rate It is easier to jam with a high feed escape up the funnel capacity. When the mud comes through the discharge nozzle, the pressure is elevated but does not rise up the funnel. The shear effect is greater when the jet mixer is used along with a shear pump.
The HV Series Vacuum Degasser can quickly remove all kinds of entrained gas from the fluids. It is an indispensable equipment in gas wells, prospect wells and deep wells. It is also used with various kinds of clean circulating systems for drilling. The gas-fluids separation structure of the HV Series degasser is well designed, ensures efficient separation and proper filtering. A water ring vacuum style degasser is used for degassing combustible gas and explosive gas
TSC’s modular design drilling fluid circulation system offers a wide variety of options for from 1000FT to 30000 FT land rig applications
