- Page 2 Technical Sales representative or contact-tenarishydril@tenaris.com. Verify the compatibility of the EasyDock™ connector with accessories such as pup joints, etc. Ensure accessories such as O-rings, spare Anti Rotation Keys (ARK’s) and ARK installation tools are available on the rig prior to operation commencement.
- Page 3 Ensure the connections are cleaned and free of all debris and / or contaminants, cleaning methods employed should conform to the recommendations contained within the TenarisHydril running manual. Visually inspect threads and shoulders as per GDL31457 “Recommended guidelines for the field inspection of TenarisHydril connections”, prior to...
- Page 4 Verify material grade of any pups or accessories are compatible with main string. Pay particular attention and note the type of connector on each item. EasyDock™ is interchangeable within same OD. When connectors with different wall thickness are combined there may be a step in the bore. Inspection...

- Page 7 Thread Compound Applicationn Ensure all connection surfaces are free of all contamination / debris and completely dry prior to doping, ensure any previously applied storage compound is completely removed. Do not use solvents on Elastomeric Seal (ELS) as they may degrade the O-ring. For Tenaris approved thread compounds, refer to FTD29356 “Premium Connection Approved Thread Compounds”.
- Page 8 Torque Application The use of computer make up analysis equipment is not necessary to make up EasyDock™ connectors. EasyDock™ assembles within ¾ of a turn from stabbing to power tight make up. A make-up is acceptable if final torque is within the defined window and there is no visible gap at the external shoulder.
- Page 9 If torque turn computer equipment is used set reference torque at zero. The guidelines indicated in the Blue and Legacy Series Make up Acceptance ® section of GDL00337 are applicable. Shoulder point should be clearly observed on the torque-turn graph. Note that quite different profiles can be obtained by changing the turn span of the graph.
- Page 10 70000 60000 50000 40000 30000 20000 10000 0.05 0.15 0.25 TURNS Graph window set at 0.3 turn. Running Alignment is critical for all pipe running operations, with large OD being even more so. Ensure travelling block / top drive is aligned with the rotary. A misalignment of 20% of the connector OD is excessive and must be corrected.
- Page 11 Ensure ARK(s) are in the unlocked position prior to stabbing. Apply Low gear and make up below 5 RPM but no slower than 2 RPM. Apply the torque indicated in the appropriate data sheet ensuring an acceptable make up is attained as previously described.
- Page 12 Stop hammering the ARK as soon as it is fully set to prevent breakage. Ensure the ARK(s) are locked in place by the lock bolt using a hexagonal key. Correct and incorrect methods of setting/ un-setting the ARK are indicated in the following diagrams. Setting: 45°...
- Page 13 ARK and the ARK slot. TenarisHydril EasyDock™ protectors are in two parts; the thread / seal protector and the bumper ring. When handling and / or storing pipe both parts must be correctly installed to pin and box in order to prevent damage to the connector, ARK(s) and ARK slots.
- Page 14 Pulling Alignment is equally as critical for pulling as it is for running pipe. Ensure travelling block / top drive is aligned with the hole, 20% deflection is excessive. The use of a weight compensator is recommended. Unlock the ARK bolt with the use of a hexagonal key. Move the ARK to the unlocked position and tighten lock bolt.
- Page 15 Disengage pin from box and pull to one side using a rope or some other form of stabilising aid to secure the pipe. This is imperative in high winds or on a floating installation, care should be taken to lower the pipe to a safe, manageable height as soon as it is lifted free of the box.
