Amsteel-Blue Slings


A Strong, lightweight and safe replacement for wire rope slings

Amsteel®-Blue
A size for size wire rope replacement made with Dyneema® fiber, 12-strand Amsteel®-Blue is easy to inspect and splice in the field, and is available in high-visibility colors. Amsteel®-Blue is our most popular and versatile, high-performance synthetic rope.

Amsteel-Blue vs. Wire Rope Comparison

AmSteel®-Blue is Samson’s most versatile, torque-free 12-strand braided rope. With well over a decade of service in the most critical marine rope applications, AmSteel®-Blue has proven to be an ideal flexible, lightweight replacement for steel wire ropes. Samson’s design uses Dyneema® HMPE fiber to provide the optimum in strength, handling, and service life.

At 1/7th the weight of comparable strength wire ropes, AmSteel®-Blue is an enabling tool in difficult offshore applications. The reduced weight, high-strength, and low stretch make it an easy choice for quick, efficient connections and controlled response. AmSteel®-Blue is proven to provide longer service life and reduced costs when compared to wire in a variety of applications.

Inspection Criteria

Any rope that has been in use for any period of time will show normal wear and tear. Some characteristics of a used rope will not reduce strength while others will. Below we have defined normal conditions that should be inspected on a regular basis.
If upon inspection you find any of these conditions, you must consider the following before deciding to repair or retire it.

the length of the rope
the time it has been in service
the type of work it does
where the damage is, and
the extent of the damage

In general, it is recommended to repair the rope if the observed damage is in localized areas, or retire the rope if the damage is over extended areas.

REDUCED VOLUME Retire or RepairWHAT
> 25% reductionCAUSE
> Abrasion
> Sharp edges and surfaces
> Cyclic tension wear
COMPRESSION Not a permanent characteristicWHAT
> Visible Sheen
> Stiffness that is reduced by flexing the rope
> Not to be confused with melting
> Often seen on winch drums
CAUSE
> Fiber Setting
CORRECTIVE ACTION Flex the rope to remove compression as needed.
MELTED OR GLAZED FIBER Retire or RepairWHAT
> Fused fibers
> Visibly charred and melted fibers yarns and/or strands
> Extreme stiffness
> Unchanged by flexing
CAUSE
> Exposure to excessive heat
PULLED STRAND Not a permanent characteristicWHAT
> Strand pulled away from the rest of the rope
> Is not cut or otherwise damaged
CAUSE
> Snagging on equipment or surfaces
CORRECTIVE ACTION
Work loose strand back into the length of the rope
DISCOLORATION Retire or Repair
WHAT
> Fused fibers
> Brittle fibers
> StiffnessCAUSE
> Chemical contamination
HEAVY TWIST Not a permanent characteristicWHAT
> The line of pics spiral around the circumference of the rope
CAUSE
> Not aligned during rigging – connection induced
CORRECTIVE ACTION
Remove lower rigging connection and straighten rope construction, reconnect and continue
INCONSISTENT DIAMETER Retire or RepairWHAT
> Flat areas
> Lumps & bumps
CAUSE
> Shock loading
> Broken internal strands

INSPECTION PROCEDURES
Internal abrasion can be determined by pulling one strand away from the others and looking for powdered or broke fiber filaments (Fig. 1 and Fig. 2)

To determine the extent of outer fiber damage from abrasion, a single yarn in all abraded areas should be examined. The diameter of the abraded yard should then be compared to a portion of the same type that has been protected by the strand crossover area and is free from abrasion damage
