MOORING LINE SELECTION Not an off-the-shelf decision For owner/operators in today’s shipping industry, safe working conditions, maximizing service life, and mitigating unnecessary failure of mooring lines are top priorities. Through proper vessel evaluation and selection of high modulus polyethylene (HMPE) ropes, Samson will show you how to achieve all three. We used to talk about mooring lines. However, with the advances in fiber and coating technology, and the innovations in chafe protection, we now talk about mooring systems. Selecting the right mooring system is not a “one-size-fits-all”...

THE SAMSON MOORING ADVANTAGE You won’t get this anywhere else Beyond selecting the right line for each component of your mooring system, Samson also provides an unparalleled service package we call The Samson Advantage. The Samson Mooring Advantage is designed for both new builds and retrofits, and adds value with critical pre- and post-sale services and an ongoing partnership program. This approach is driven by safety and is a proven model that cannot be duplicated by any other rope manufacturer. Whether it is vessel inspections prior to the sale, crew training for proper rope handling and splicing,...

MOORING LINE SELECTION CONSIDERATIONS

MOORING LINE SELECTION CRITERIA Rope Design: Jacketed vs. Non-Jacketed One of the best ways to combat unforeseen situations and prevent failure is to select the mooring line and tail, or pendant, appropriate for your vessel. Many ship owners, managers, and terminal operators are aware of the advantages of ropes made with Dyneema® fiber and have become accustom to asking for jacketed mooring lines. There is a perception in the industry that jacketed construction provides a longer service life because the strength member, typically made with a high-performance fiber, is protected by the outer jacket....

UNDERSTANDING ABRASION External abrasion without protection Abrasion is one of the biggest culprits of line damage. There are two types of abrasion: internal abrasion caused by the relative movement of internal and external yarns; and external abrasion caused by contact with external surfaces, such as roller and panama chocks. An unprotected rope moving over a rough surface, such as a poorly maintained chock, can be subjected to both. Upon inspection, it’s easy to see when the external strands are abraded by a rough surface. Often, fibers can be left behind on the surface that caused the abrasion...

INSTALLATION After surfaces have been prepped, the working line should be installed on the winch with significant back tension. The device used to create the tension should have a smooth and consistent surface, and the installation speed or tension applied should not generate excessive heat build-up in the rope. As the line is wound onto the winch, it should be closely packed to minimize areas where the rope may “dive” or bury into the layers of the winch. Install each layer in the valleys of the previous layers or crossed over each other to support each subsequent layer. Never stack the layers...

Inspection Guidelines and Residual Strength Testing Regular inspections and repair as needed will extend the working life of highperformance mooring lines. Any rope that has been in use for a period of time will show normal wear and tear. Some characteristics of a used rope will not reduce strength while others will. Below we have defined normal conditions that should be inspected on a regular basis. The following criteria should be considered when inspecting 12-strand ropes made with Dyneema® fiber: If upon inspection you find any of these conditions, you must consider the following before deciding...
