PES PA PP

Polyester (PES)

  • Most durable of the common materials
  • High strength, both wet and dry
  • Good resistance against external abrasion
  • Does not lose strength rapidly due to cyclic loading
  • Low coefficient of friction allows it to slide easily around bitts
  • Relatively high melting point (256°C) reduces the chances of fusion
Polyester is therefore useful for large and small rope material where strength and durability are important and where moderate elasticity is required.

Polyamide (PA)

  • Rope loses 10 – 15% of its strength when wet
  • Highest elasticity of regularly used materials
  • Good temperature and abrasion resistance
Its high elongation characteristics makes polyamide ideal for applications where shock loading occurs, such as mooring tails.

Polypropylene (PP)

  • Approximately same elasticity as polyester rope
  • Limited temperature resistance
  • Poor cyclic loading characteristics
  • Prolonged exposure to the sun's ultraviolet rays can cause polypropylene fibres to disintegrate due to actinic degradation
  • Lighter than water
Polypropylene ropes can be used for floating messenger lines. The use of moorings manufactured from 100% polypropylene is not recommended. However, suitable composites or melt mixes with other fibres such as polyethylene or polyester are available and acceptable for use as moorings.



Bexcoline

Our Bexcoline ropes are the result of our special extrusion technology and are made of highly abrasion resistant yarns. A special marine finish is applied to further increase the wear resistance in a marine environment. This finish has been tested conform ASTM D6611-00 and is water repellent.

  • Very high strengths comparable to nylon and polyester for much lower weights
  • UV stabilized
  • Very good abrasion resistance
  • Excellent fatigue characteristics
  • The rope does not absorb water
  • Wet and dry strength are identical
  • Excellent handling characteristics due to the very high strength per weight ratio
  • The ropes conform to INTERTANKO and OCIMF guidelines for tanker moorings
Depending on the specific requirements of the customer, we can offer different types of composite ropes: Bexcord (specific gravity of 0.91) is a melted mix of polypropylene and polyethylene and thus 100% floating. The ropes offer a better abrasion resistance and have a much higher strength than standard polypropylene ropes. BexcoFloat (specific gravity of 0.99) and BexcoFlex (specific gravity of 1.1) are produced with polyester fibres covering a polyolefin core. The polyester fibre is giving the rope a superior abrasion and friction resistance due to its higher working and melting temperature. Our BexcoFlex is not only used as mooring rope, but is also most suitable to be used as a tail, as a superior alternative to the traditional nylon tails.


Dyneema

Dyneema® is a High Modulus PolyEthylene (HMPE) fibre offering maximum strength combined with a minimum weight:
  • Highest strength per weight ratio
  • Very good abrasion resistance
  • Excellent fatigue properties (the lifetime in cycling over sheaves is extraordinary)
  • Good resistance to axial compression
  • Low stretch characteristics
  • Limited temperature resistance (melting temperature of 150°C and maximum working temperature of 65ºC)
  • Fibre density of 0.97
  • Floating
Low stretch ropes are advantageous where limited movement is required, such as at berths with hard arm equipment and where low dynamic loads are expected. Ropes made with Dyneema® are particularly recommended for quick and safe mooring and towing and in some offshore and industrial applications where weight and easy handling are an issue. They are also used in various applications in commercial fishery, like net panels, cod ends, warp lines, but is also an excellent material for selectivity panels resulting in a strongly decreased bycatch


Applications

Tankers
Containerships and ferries
Cruiseships
Navy and inland shipping
Towing

Mooring tankers

Our Bexcoline Composite ropes are particularly suitable for general mooring on bitts or mooring drums:

Bexcord

  • Melted mix of polypropylene and polyethylene
  • Better abrasion resistance
  • Much higher strength than standard polypropylene ropes

BexcoFloat and BexcoFlex

  • Produced with polyester fibres covering a polyolefin core
  • Superior abrasion and friction resistance
  • Much higher strength than traditional polyamide (nylon) and polyester ropes
These ropes are easily spliceable and conform to INTERTANKO and OCIMF guidelines for tanker moorings.

For larger tankers, like LNG carriers, ULCC & VLCC we have developed our Ultraline® ropes made of Dyneema®:
  • Load-bearing cores made with Dyneema® and a cover of polyester composite yarn
  • The cover is optimised for wear and abrasion resistance
  • The cores are optimised for strength
  • The lifetime under fatigue loads is extraordinary

Mooring Containerships & ferries

Our Bexcoline Composite ropes offer a reliable and cost effective solution for safe and quick mooring:

Bexcord

  • Melted mix of polypropylene and polyethylene
  • Better abrasion resistance
  • Much higher strength than standard polypropylene ropes
  • BexcoFloat and BexcoFlex
  • Produced with polyester fibres covering a polyolefin core
  • Superior abrasion and friction resistance
  • Much higher strength than traditional polyamide (nylon) and polyester ropes


For larger container ships and ferries, our 6-strand Atlas® and Caesar ropes are the ideal choice:
  • Ropes made from high-tenacity polyamide, whereby mono- and multifilaments are combined in the strands
  • The hardwearing monofilaments give the ropes excellent dimensional stability and abrasion resistance
  • The ropes are very compact and are designed for use as winch-mounted lines
  • The splicing technique for Atlas® is very similar to that of wire-ropes

Mooring cruiseships

Our Bexcoline Composite ropes are particularly suitable for general mooring:

Bexcord

  • Melted mix of polypropylene and polyethylene
  • Better abrasion resistance
  • Much higher strength than standard polypropylene ropes

BexcoFloat and BexcoFlex

  • Produced with polyester fibres covering a polyolefin core
  • Superior abrasion and friction resistance
  • Much higher strength than traditional polyamide (nylon) and polyester ropes
For the biggest and most modern cruise ships we have developed our Ultraline®ropes made of Dyneema®:
  • Load-bearing cores made with Dyneema® and a cover of polyester composite yarn
  • The cover is optimised for wear and abrasion resistance
  • The cores are optimised for strength
  • The lifetime under fatigue loads is extraordinary

Mooring navy and inland shipping

Our Bexcoline Composite ropes (see higher) are perfectly suitable as a reliable and cost effective mooring line. For quick moorings, 8 or 12-strand ropes made with Dyneema® offer many economic and safety advantages: they are stronger, lighter, easier to handle, safer, require less maintenance and are more durable.

Towing applications

The towline is a vital element in any towing operation as it connects the towed vessel to the tug. The choice of towing line can be critical as no towing operation is identical. BEXCO offers various types of towing arrangements and can help you making the right choice considering various factors like local rules and guidelines (safety factors), general weather conditions, propulsion system, crew and port conditions.
