Harbour towing rope

The Dextron® harbour towing rope is made with Dyneema® fiber and can be covered with a OTS Protective jacket™. The patented OTS Protective jacket™ gives excellent protection against abrasion on the rope. The Dextron® ropes provide for durability, reliability, longer service lifetime, low operation costs and safer operations. Because of light weight of the rope, the operations can be done faster and less manpower is needed.

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





  • 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.
