Technical Bulletin Frequently Asked Questions What are AmSteel®-Blue Mooring Lines and what are the benefits of using them? AmSteel®-Blue Mooring Lines are produced with a synthetic fiber called Dyneema® SK-75 fiber, an ultra high molecular weight polyethylene material. The use of this fiber allows usto create a torque-free, 12-strand braided rope which, size-for-size, has comparable strength to wire rope but only 1 /7th the weight. An example of an HMPE working line is AmSteel®-Blue which is flexible, easy to handle and floats. The unique blue color is there for more than just appearance — It is created by a proprietary Samthane coating that enhances rope wear life and snag resistance. AmSteel®-Blue doesn't require lubrication because it doesn't rust or "fishhook." Its flexibility and extreme light weight will allow for an easier, faster and safer mooring When converting from wire rope mooring lines to AmSteel®-Blue mooring lines, what implementation procedures are required? Chock and fairlead maintenance should be instituted to eliminate rough wearing surfaces, metal burrs and sharp cutting edges that could have been created by the use of wire ropes. In the majority of cases, the conversion can be done as routine maintenance with localized grinding and surface preparation. How will AmSteel®-Blue synthetic line wear compared to wire line? The Dyneema® SK-75 fiber used in AmSteel®-Blue is also utilized for bulletproof vests, military helmets and cut-resistant gloves. It is a tough material. It should be noted, though, that all synthetic fiber can be cut, therefore care should be taken to protect the mooring line from sharp and rough surfaces that it could be worked against or over. As the rope is used, it will develop surface wear on the outer fibers. This individual fiber abrasion will give the line a fuzzy appearance. Due to the normal external wear from use, the line will also gradually begin to lose its original royal blue color. Can AmSteel®-Blue mooring lines be repaired aboard ship? Yes! The 12-strand construction of AmSteel®-Blue is one of the easiest ropes to splice or re-splice. AmSteel®-Blue can be spliced with new eyes by following the instructions available on our website or in your owner's manual. THE STRONGEST NAME IN ROPE

Technical Bulletin Frequently Asked Questions How should the AmSteel®-Blue mooring lines be installed on deck winches? The correct installation of this mooring line on deck winches is important to the long-term service life and performance of the rope. 1. After the removal of the old wire rope lines, and before installation of the new AmSteel®-Blue ropes, please inspect the winch drum and flanges for rust, corrosion or scoring damage created by the wire rope. These areas should be cleaned up so as not to cut and abrade the new ropes being put on. See our technical bulletin on retrofitting...
