MUD SPILL PROTECTION TELESCOPIC JOINT

As a result of authorities demanding zero spillage from drilling operations, Sub Sea Services have developed a mud spill protection system that monitors and collects the mud fluid coming from the Telescopic Joint packers. Undetected packer wear or failure can result in accidental spillage of drilling fluids into the environment. The system´s continuous circulation ensures constant lubrication and cooling of the packers, and since the levels of the fluid is constantly monitored, the system acts as an early warning system for spill prevention. If a packer fails, the system is designed to alert the drilling control room, energize the back-up packer, collect the mud and discharge the contents into rig waste.

RIG COMMUNICATION

The mud collector skid unit is located on the cellar deck. The unit contains the mud spill protection monitor, the fluid tank, circulation pump and an optional packer monitoring system.

The umbilical contains the mud line, power supply for the air pump and the communication sensor lines between the mud bucket and skid unit. The umbilical varies in length depending on the moonpool layout and runs through a saddle to secure the umbilical during operations. Location will depend on moonpool layout.

The monitor communicates with the drilling control room, providing continuous monitoring of bucket mud and fluid levels. In the event of detection of a spill, an alarm and warning lights will go off in the drilling control room. Approx weight is 1,5 T. A recommended option is to install a packer monitoring system on the skid unit.

TELESCOPIC JOINT MODIFICATION The mud collector bucket is mounted onto the packer housing on the T-joint. The mud collector bucket has a low and high fluid level sensors. A filter covers the bucket to prevent solids falling into the bucket. The air pump is designed to constantly circulate the fluid and has a capacity of approximately 15 cubic meters pr hour. This constant circulation ensures good lubrication of the packers and reduced risk of packer failure. The telescopic joint modification depends on the telescopic joint type but all designs ensure normal operation and that the telescopic joint fits through the rotary.
