Spur line

The Dextron® Spur line is made with Dyneema® fibers and is as strong as steel wire, with only one-seventh of the weight. The ropes have low elongation and are protected with the patented OTS protective jacket™ to avoid damage on the rope. Dyneema® hairy fairing and/or solid foil fairings are being fitted onto the rope to reduce drag.

Dextron®12 Plus

Dextron®12 Plus is a torque-free, 12-strand braided rope with maximum strength-to-weight ratio and size-for-size has the same strength as steel. Dextron®12 Plus is made with Dyneema® SK78 and is an excellent wire rope replacement with extremely low stretch, superior flex fatigue and wear resistance.

Dextron®12 Plus is Type-Approved by DNV. Download certificate

OTS Protective jacket™: Patent no: 314459

The patented chafe gear - OTS Protective jacket™ - offers excellent protection against external abrasion and increases rope lifetime with up to five times. The "no-rupture" construction combined with the worlds most abrasion resistant synthetic fibers, makes this the best cut -and abrasion resistant cover for your ropes. The jacket is mechanically braided onto the rope for a firm and solid finish.

OTS Protective jacket™ is braided in the following combinations:

Soft eyes
Soft eyes and required length (for instance over the splices)
Exposed area on the rope
Entire rope length

OTS Protective Jacket™

Made with HMPE or polyester fiber.
The OTS Protective Jacket™ comes out as a clear winner in comparative testing of abrasion and cut resistance.
Excellent protection against wear and tear.
Patented technology

Advantages

Increases service life.
Can be braided onto entire rope or exposed areas.
Prevents rope from twisting.
Protects rope from external abrasion.
Reduced size of mooring line.
Reflective material can be woven into jacket band for better visibility.
Jacket band can be delivered in any colour.

Fairing reduce the turbulence that occurs when a object is being towed through the water. The fairing OTS supply comes in two types; hairy fairing and solid fairing.

The hairy fairing is either tied to the rope by hand or automatically braided into the protective jacket™. The hairy fairing can be made with fibers like PE-yarn, Danline, Dyneema® or Polyester. Recent years testing in laboratory and fieldtests has given further information about the effect of reducing drag by means of fairing. OTS is continously developing new fairing types based on information from these type of tests. Contact us to learn more about our recent developments.

The solid fairing is a wing shaped component mostly made of PE or similar material. The fairing is - at its name states - a solid construction that is beint threaded onto the rope and secured to the rope every 5 or 10 meters. This fairing type is especially effective on drag reduction where the rope is being towed in a transverse direction.
