02 - <strong>FIBRE</strong> ROPE<br />
Care<br />
Storage - fibre rope should be stored in a dry unheated room<br />
with free air circulation. Keep loose coils off the fl oor.<br />
Dry properly after wetting - sisal and manila fi bre ropes<br />
should never be stored wet as mildew and other microorganisms<br />
can occur under damp or humid conditions. You<br />
should carefully dry the rope out under atmospheric conditions<br />
and store in the correct manner. Synthetic or man-made ropes<br />
are not generally attacked by mildew.<br />
Protect from chemicals - acid, acid fumes and alkalis, are<br />
highly injurious to rope. Storage battery solutions, washing<br />
compounds or solution and paint, all will cause deterioration of<br />
the fi bre.<br />
Use<br />
Inspect - you should always inspect your rope PRIOR to use<br />
for any nicks, cuts, kinks, chafi ng or tears.<br />
Avoid kinks - when rope is repeatedly twisted in one direction,<br />
kinks are certain to develop - unless twist in the opposite<br />
direction is thrown in, or out, of the rope. Kinks pulled through<br />
restricted space, such as tackle block, will seriously damage the<br />
rope.<br />
Don’t overload - Use a 6 to 1 safety factor based on the<br />
minimum breaking force of a new rope, Overloading may cause<br />
permanent elongation.<br />
Avoid sharp angles or bends - fibre is somewhat elastic<br />
and, as a sling or lashing will ”hug” an object. However, sharp<br />
corners and angular bends put a heavy strain on the outer<br />
fibres of a rope and should be avoided if possible.<br />
Avoid unnecessary wear and abrasion - the outer fibres of<br />
a rope, no less than the inner ones, contribute to its strength.<br />
When they are worn - by chafi ng or dragging over a rough, gritty<br />
or splintered surface the rope is weakened.<br />
Avoid sudden jerks or strains - a rope may be extremely<br />
diffi cult to break with a pull but can be easily be broken with a<br />
snap. A sudden jerk on tackle, slings or lashings may result in<br />
breaks that would never occur with a steady, natural pull.<br />
Blueline - Polypropylene Rope 3 Strand Extra<br />
Strength<br />
High strength rope made from extruded polypropylene yarns.<br />
Excellent abrasion and shock absorption. They are tough,<br />
extremely strong and have excellent knot ability. They are<br />
the same strength wet or dry and are UV stabilised.<br />
Suggested applications: Truck ropes, nets, ladder ropes, foot<br />
ropes tarpaulin ties, blasting mats, car tow ropes, air sea rescue<br />
lines, slings, control ropes, headlines, ducting draw cords.<br />

AmSteel ® -Blue<br />
12-STRAND CLASS II<br />
SAMSON PRODUCT CODE: 872<br />
Recognised worldwide as the standard for single braid HMPE ropes<br />
AmSteel ® -Blue is a torque-free 12-strand single braid that size for size, is as strong as steel<br />
but outlasts wire 3:1, making it an excellent wire rope replacement. At only 1/7th the weight<br />
of wire, it is a safe and efficient solution for all marine applications where wire is traditionally<br />
used. The combination of Dyneema ® fibre and Samthane coating provide abrasion and<br />
tension fatigue resistance for superior wear. AmSteel ® -Blue is easily spliced and inspected.<br />
AmSteel ® -Blue is recommended for split-drum winch applications. It is not recommended<br />
for use on H-bitts, capstans, or cleats if surging or rendering the rope is required.<br />
FEATURES AND BENEFITS:<br />
> Made with Dyneema ®<br />
> Wire rope replacement<br />
> Size for size as strong as wire<br />
> 1/7th the weight of wire<br />
> Similar elastic elongation to wire rope<br />

*For optimal performance, mitigating abrasion over a chock, Samson recommends AmSteel ® -Blue in up 4–6mm over the wire rope you are replacing.<br />
**This standard replaces BS EN 919 and ISO 2307:1995 and is for unspliced strengths.<br />
SAMSON LINE SELECTION<br />
FACTORS TO CONSIDER<br />
A number of factors should be considered<br />
when selecting a Samson line, such as<br />
> intended use or application,<br />
> potential abrasion issues,<br />
> surface preparation,<br />
> rope design/construction,<br />
> chafe protection,<br />
> proper installation procedures,<br />
> inspection schedule, and<br />
> retirement criteria.<br />
Samson works with you to ensure that there<br />
is a comprehensive understanding of each<br />
of these considerations to en-sure a long<br />
service life and mitigate unnecessary failure.<br />
UNDERSTANDING ABRASION<br />
Abrasion is one of the biggest culprits of line destruction. There are two types of abrasion:<br />
internal abrasion caused by the relative movement of internal and external yarns; and external<br />
abrasion caused by contact with external surfaces, such as roller and panama leads. External<br />
abrasion is usually easy to see on any rope, while internal abrasion is easier to inspect in a<br />
single-braid rope. When a rope moves over an abrasive surface, both factors contribute to<br />
causing the outer surface to move slower, while the internal fi bres continue along their original<br />
path. Heat results from this type of friction and heat is an enemy of synthetic fi bres.<br />
MITIGATING THE EFFECTS OF ABRASION<br />
Dyneema ® is a registered trademark of Royal DSM N.V.<br />
Dyneema ® is DSM’s high-performance polyethylene product.<br />
Vessels and equipment that have traditionally used wire rope often<br />
have sustained significant damaged caused by fi shhooks, broken strands,<br />
etc., which come in contact with the deck and other equipment. These<br />
conditions can damage or significantly reduce the life expectancy of ropes<br />
made with Dyneema ® . However, preventative measures can be taken to<br />
mitigate these issues by repairing all rope contact points to a smooth and<br />
consistent surface.<br />
The addition of chafe protection utilised on the areas of the line most likely to suffer from abrasion<br />
is critical for the rope’s longevity. These are either sleeves that slide on the rope or spliced into a<br />
line, depending on the construction of the rope and its use.<br />

ROPE DESIGN AND CONSTRUCTION<br />
One of the best ways to combat unforeseen situations and prevent failure is to select the line<br />
for the application. The advantages of nonjacketed lines are numerous: they are stronger than<br />
jacketed lines size for size and they are easy to inspect and repair. Unlike jacketed lines, which<br />
rupture in the areas that suffer the greatest abrasion and have to be replaced, only the chafe<br />
protection on a nonjacketed rope has to be replaced, saving time and money. A 12-strand<br />
mooring line system such as AmSteel ® -Blue with Dynalene chafe protection provides the<br />
ultimate in cut and abrasion resistance, and the rope maintains its strength for the long-term.<br />
