Global Gravity was established in Esbjerg in 2011, and specialises in transporting casing, tubing, and drill pipes for the oil industry. The company is the inventor of the patented TubeLock system, which is the world’s first “Tubular Transport Running System” (TTRS).

 

With TubeLock, Global Gravity are taking care of all handling and transportation of all types of casing, tubing and drill pipe tubing from storage, across the quay to the ship, and onto the drilling rig. TubeLock improve safety and efficiency significantly for the offshore operators.

Pipe handling can be quite a dangerous job if it is not carried out correctly and because of threats from the outside. Every day, the crew work in harsh conditions, exposed to wind, cold and noise in a very challenging working space. There is a great risk of injury to people and damage to equipment. It is not far from the walkway to the edge, and bulldog clamps and tools have been dropped on several occasions. With traditional wire slings heavy loads of pipes are rolled out, stacked and bundled with 10- to 12-metre-long steel wires, causing danger to the people working when unloading and dangerous stored energy released when the slings are removed from the bundled pipes.

TubeLock reduce these risks as the pipes are stored and transported in a safer manner and are stacked according to all safety criteria. With TubeLock there are less manual handling and most preparations can be done onshore.

Furthermore, surveys show that customers reduce time spent on the overall handling process by 50% compared to the traditional solutions. At the same time, TubeLock requires 50% less space and halves the amount of handling out on the drilling rig. Using the TTRS Systems you can run the tubulars directly out of the TTRS frames as they are all measured and numbered. You can run the pipes directly into the wellbore from the TubeLock system, therefore there are no requirements for the rig crew to unload the frames and lay the tubulars out on the pipe deck reducing the handling of tubulars on the Rig and supply boat by 50%.

It is a documented fact that our operators save 50% of the time normally used moving pipe from supply boat to cantilever deck on the drilling rig ready to be run in hole. The time saved offloading boats free the deck crew and cranes for more important tasks related to the drilling operation. And saves both fuel on cranes and supply vessels during the operation.

As pipes does not have to be laid out upon arrival on the rig, handling is reduced by at least 50% thereby reducing risk of dropped objects and injury to personnel.

TubeLock is certified as an offshore lifting appliance under DNV ST-0378 and Norsok R02 and is in compliance with ILO and LOLER recommendations.

TubeLock is manufactured from Aluminum to ensure it is easy to handle and no single part weight more than 15 kilos. The aluminum base product also ensure there is no galvanic corrosion between TubeLock and chrome alloy tubes

Sand-Screens is yet another product that we have successfully transported, saving the operators time and space by not having to use large transport baskets which take up cumbersome space on the supply vessel even when returned empty. The cost of chrome and super chrome tubulars are some of the highest costs when drilling and completing wells and there is a high risk of damaging these tubulars when bundling and slinging Chrome Tubulars. When these tubulars are transported in the TTRS frames they are protected and cannot be damaged.

A work group set up by UK Oil and Gas and Step Change to review lifting incidents, has highlighted the practice of bundling and slinging tubulars to be a high risk process and that we should work to eliminate that process within a timeframe agreed by all industry participants.

“We believe that TubeLock® TTRS will be the future for all involved with pipe transport, storage, inspection and drilling.”

Our Track record is as follows:

  • UK Operations – 3-1/2” to 9-5/8” (Equinor – 13 wells)
  • Qatar Operations – 3-1/2” to 13-3/8” (North Oil Company – 5 year contract - 4 No. rigs )
  • Denmark Operations – 3-1/2” to 13-3/8” (TOTAL – 5 Year Contract)
  • Australia Operations – 4-1/2” & 7” (Santos)
  • Trinidad Operations – 5-1/2” Bakers Sand Screens (BHP)
  • Norway Operations – 4-1/2”, 5-7/8” & 7” (Var Energi, AKER BP & Neptune)
  • Holland Operations – 4-1/2” to 9-5/8” (Tulip Oil, Wintershall Noorzdee BV, NAM)
  • Germany Operations – 2-7/8” to 9-5/8” ( Wintershall DEA – 5 Year Contract)

Global Gravity supply the world´s first Tubular Transport Running System (TTRS). TubeLock® provides optimization of all processes for pipe handling within all types of well interventions and drilling operations around the world. Giving our global customers great cost savings in combination with the safest and most effective TTRS for all types of pipes used by drilling rigs.
