COBRA Wash & Dope Tool
COBRA Wash & Dope Tool
Most drilling rigs have fully automated derrick and pipe handling systems. In certain regions the legislation prohibits personnel to work on the drill floor while the automatic pipe handling machines are in use. But still we experience personnel using HP cleaners and manual dope brushes when drill pipe and other tubulars are cleaned and doped prior to connection.


Facts
The COBRA can be installed in two different ways - stand alone or integrated with the pipe handling system. It can we tailor-made to fit most drill floor applications and to be used with most types of pipe handling equipment
As stand alone the COBRA is placed conveniently on the drill floor. When the DP moves from setback area towards well center the pipe handler makes a wash and dope stop. The COBRA will raise vertically and position itself embracing the DP pin end. After engaging a 360 degree sequence using HP water will wash the threads and apply dope. After a few seconds the DP can move on.
When integrated the COBRA is installed on the pipe handler/racker. The COBRA will raise to engage with the pin end and to carry out the wash and dope sequence.
Wash time and applied dope volume are PLC controlled parameters. The COBRA require power, HP water, air and dope to operate. It is ATEX certified, Zone 1, CE certification, etc. Optional choices are:
- Dope pump stand alone. Data tracker and heat tracing available.
- HP Wash Down Unit, integration available.
- Supply station. Dope pump and HP Cleaner build into cabinet.
Advantages
Easy to install on the drill floor or pipe handler.
The COBRA will wash and dope the DP tool joints automatically and ensure clean threads before applying correct amount of dope.
Air-driven cylinder ensures gentle tool interaction with DP. Self-cleaning interior wash/flush sequence. Drain hose connection, no spill on drill floor. No personnel in drop zone while tripping in hole.
Benefits
Releases human resources. Personnel avoid the danger of dropped objects or working close to remote operated machines on drill floor (Red Zone).
No over torqued connections. Not taking up iron roughneck time (as when pipe doper is installed on iron roughneck).

BHA Wash Tool
BHA Wash Tool
The high level of safety in today’s drilling operations around the world require special attention to
equipment. Most drilling rigs have fully automated derrick and pipe handling systems. In certain
regions the legislation prohibits personnel to work on the drill floor while the automatic pipe
handling machines are in use. But still we experience personnel using HP cleaners when BHA is
pulled through rotary.




Facts
The tool is tailor-made to fit on top of the diverter or bell nipple. It connects to the rig’s HP system or a special HP unit fit for purpose. Actuation of HP water can be done locally on the drill floor or remotely from driller’s cabin.
The BHA Wash Tool can be installed either with three legged sling or with the special made Running Tool.

Reviews
we have really good experience with this washer Performance Coach - Valaris Viking
The BHA wash tool has worked as intended. In my opinion this is a step in the right direction that every drilling rig should consider. It enables us to stay in compliance with red zone requirements without compromising the quality of the craftsmanship on the rig floor. We keep the floor clean while pulling BHA, which is a HSE benefit as a slippery deck represents a risk. It saves time, not having to stop and clean BHA for every couple of meters. The deck crew is also happy, as the string components coming out are cleaner than before.Roger Løvslett, Operations Planner -- TRANSOCEAN SEARCHER
