Samson's DeepCool Technology: Taking the challenge of deepwater operations.
DeepCool Logo

Samson’s DeepCool™ Technology significantly increases performance in operations where cyclic bending over sheaves is an issue.

As exploration and production moves into increasingly deeper waters, the challenges of subsea equipment installations, anchor handling, and pipe laying increase proportionately. As a result lowering and lifting equipment with heavy wire rope is becoming more sophisticated, heavier and more demanding of power. High-performance synthetic ropes are stronger and lighter than wire. This allows handling equipment with a smaller footprint, lighter weight, and reduced power requirements. Samson has developed DeepCool™ Technology to give its high-performance synthetics significantly increased CBOS-fatigue (cyclic bend over sheave) life for use in lowering/lifting operations that require the use of active heave compensation systems.

Traction Winch

DeepCool™ allows engineers to specify handling equipment with a reduced footprint, requires less power to operate and winch lines need to be replaced less frequently in critical deepwater equipment installations.

 

Cyclic Bend Over Sheave (CBOS) Test Results

Testing on CBOS test equipment conducted together with W. L. Gore and Associates confirms that DeepCool™ Technology increases the bend-fatigue resistance of ropes by a significant factor.

CBOS Cycles to Failure

The CBOS tension was set to 18,500 lbs. during all tests. Based on the average break strength of the control ropes (92,630 lbs.), the test tension was selected to provide a safety factor of five—an industry-wide accepted value. Because the break strengths of the ropes with ePTFE fiber varied slightly from that of the control ropes, the safety factor for the testing of those ropes may have varied up to 10 percent.

 

Increased Bend Fatigue Life

Samson high-performance synthetics with DeepCool™ Technology are stronger, lighter, and last significantly longer in situations of repetitive bending compared with wire ropes or other high-performance synthetics without DeepCool™ Technology.

Heat is the Enemy of All Ropes

DeepCool™ significantly reduces internal heat generation from CBOS. The result is a longer, more reliable service life for ropes subjected to the rigors of heave compensation systems.

Internal heat generated by cyclic bend over sheaves (CBOS) is significantly reduced with DeepCool™ Technology.

DeepCool™ Technology extends the life of high-performance synthetic ropes used in lifting and lowering operations in deep and ultra-deep water:

  • Reduces generation of internal heat
  • Increases bend-fatigue resistance up to 10 times that of untreated ropes

Compared to wire rope in winch-based lifting and lowering systems, Samson high-performance synthetic ropes are:

  • As strong or stronger, size for size, than wire ropes
  • 1/7th the weight — they’re weightless or nearly weightless in water
  • Winches and handling equipment power requirements are reduced
  • Smaller deck equipment footprint, reduced deck loads and demands on ship-weight capacities
  • Easier handling, safer operations

And, best of all, with DeepCool™ Samson high-performance synthetic ropes last longer in critical deepwater applications.
