2 THE SAMSON TUG ADVANTAGE 2

3 TUG SYSTEM SELECTION Not an off-the-shelf decision The tow rope is arguably the single most important piece of equipment in the industry. It s the dependable connection between your vessel and the vessels in your care. For owners and operators in today s towing industry, safe working conditions, maximum service life, mitigated failure of tow lines are top priorities. Through proper evaluation and selection of high modulus polyethylene (HMPE) ropes, Samson will show you how to achieve all three. The right rope for every component. We used to talk about tow lines. However, with advances in fiber and coating technology and innovations in chafe protection, we now talk about towing systems. Selecting the right rope for each part of the towing system is not a one-size-fits-all proposition. Each component should be considered independently pendant, mainline, and backer. Based on specific needs, each component is selected to give you the best overall system and performance. We understand the factors that weigh into these decisions and will help you select the system to get the job done correctly and safely, providing the best value for your investment. We want your system to be as safe as possible for as long as possible. It may seem counterintuitive for a supplier to help you get more life out of their products; but at Samson, that is exactly what we do. We understand that adding real value to your business is how we become an indispensable partner. Knowing the intended use or application of the rope is not enough. There are a number of factors that should be considered when selecting a towing system and protecting your investment for a long service life: > Vendor expertise and support > Measuring real value cost per tow vs. cost per line > Understanding abrasion > Protecting your investment A.

6 THE ULTIMATE TUG SYSTEM COMPONENTS 6 Photo Brian Gauvin

7 IT S NOT JUST A ROPE, IT S A SYSTEM With high bollard pull tugs becoming the norm for harbor tugs in ship assist and escort jobs, the tow line needs to evolve to take full advantage of the tug s capabilities and capacities. Ropes made from high-performance fibers such as Dyneema HMPE are lightweight, strong, and dependable, but that s not all that s required with today s tugs and winches. Each component needs to be perfectly suited to its mission in order for the full system to provide greater efficiencies, easier handling, and longer service life. Samson s towing system has been proven to outlast and outperform any tow system on the market. The result is increased value by any measure. THE PENDANT At the business end of the line is the pendant. Once the pendant passes through the chock, you ve lost complete control over the conditions a line encounters. The pendant is designed to be sacrificial and withstand abuse as long as possible, then be replaced as needed. Because it is designed to take the brunt of the abrasion, it is often stronger than the mainline. Adequate chafe protection also helps mitigate the possibility of damage to this critical section of the tow line. Saturn-12, with its proprietary coating that reduces internal and external abrasion, is a good match for the rigors of duty as a pendant. Saturn Dynalene makes a perfect match for chafe protection. The combination provides a durable and strong pendant. DC Gard can also be used effectively. THE MAINLINE The mainline is next. This is the main strength member of the system and its longest component. It needs to be strong and pack well on the drum. Here, Saturn-12 or AmSteel -Blue have proven to be the best choice. Strong and dependable, yet lightweight and easy to handle by deck crew, these two have shown themselves to be the superior ropes in this application. These 12-strand single braids are easy to inspect and simple to splice when required. For conventional tugs working from H-bitts, Proton -8, Quantum-X, or Quantum-8 are the preferred choices. Quantum-X and Quantum-8 have Samson s patented DPX fiber technology for increased coefficient of friction in a high strength, lightweight rope that incorporates polyester with Dyneema HMPE fiber. For modern tugs working with conventional winches, where mainlines are made with traditional fibers (Class I) and jacketed with non-inspectable PP/PPE blends, Fusion-12 provides a lighter weight, inspectable, flexible, longer-lasting crew-friendly alternative. The system can be configured to meet your specific needs. If there is a potential for shock loading the mainline, add a section of rope with higher elongation than HMPE. This will allow the operator to extend the mainline to bring the higher elongation section into play during the operation. Quantum-X backer line eye-to-eye connection to a Saturn-12 mainline with Dynalene chafe protection. THE BACKER LINE The tow line system starts with a backer line that doesn t compromise the mainline s strength, but provides the best purchase on the winch drum. High-performance lines with a higher coefficient of friction, such as Quantum-X with DPX fiber technology, work extremely well as backer lines the first two layers on the winch drum. They also provide a better grip at the drums attachment point. Backer lines make end-for-end procedures significantly easier. Simply unsplice the small eye and re-splice it at the other end of the mainline. With this procedure, there is no need to deal with a clamp. 7

8 CALCULATING COST TOW 8

9 MEASURING REAL VALUE: Cost per tow vs. cost per line Don t be content to purchase new tow lines on price alone. There are other variables that should be factored into the cost equation. These factors include how long a rope is in service, the vessel type, and the operations the vessel typically performs. All of these factors will lead to the true cost of ownership of the towline. We call it cost per tow (CPT). IDENTIFYING THE CPT FOR EACH VESSEL Our program uses individual vessel history to determine the best line for specific types of operations. The first step is to collect the vessel data, usually found in the deck logs. Accurate results require a minimum of: > Information for the last four pendants used on the vessel > Number of tows performed by each line > Current status either active, retired, or failed > Rope construction and fiber type > Cause for line replacement CALCULATION Original CPT = purchase price of the tow line ( ) Number of tows ( ) before the line was retired or failed THE RESULTS One fleet who implemented a CPT program, which is in use today, realized the following after the first year of recordkeeping: > The number of rope failures had been reduced by 85% > Service life increased by times the original rope In addition, the new protocol for crew training in proper handling, inspection techniques, and improved line management, further affecting the overall cost of operations. If you would like to see how using this program could benefit your operations, contact your Samson representative or call customer service to set up a meeting with one of our sales engineers. TRACKING EXAMPLE: LINE / TYPE INITIAL COST AVERAGE # OF TOWS RETIREMENT DATE COST TOW LINE A / Pendant $20,300 3,300 8/19/2016 $6.15 LINE B / Mainline $36,000 9,200 1/20/2017 $3.91 The CPT is calculated by dividing the original purchase cost of the rope by the number of tows before it was either retired or failed. 9

11 UNDERSTANDING ABRASION While high-performance ropes made with Dyneema fiber are naturally cut and abrasion resistant, abrasion is still one of the main causes of rope failure in ship-assist operations. If no remedial actions are taken, abrasion will reduce the rope s residual strength and ultimately affect the reliability and shorten the service life of the towline. There are two types of abrasion external and internal. Both are caused, at least in part, by the rope s movement over rough, poorly prepared and maintained surfaces. EXTERNAL ABRASION is easy to spot broken fibers at the surface of the rope give it a fuzzy appearance. Visual inspection and an appraisal of the percentage of fibers that are damaged is a relatively simple process. INTERNAL ABRASION, caused by the relative movement of strands and fibers within the rope, is indicated by broken, powdered, or fused fibers within the rope s construction. Repeated bending over fairleads, chocks, or sheaves is often the culprit here. Opening up the rope and inspecting the fibers within is easily accomplished on 12-strand or 8-strand single braids but virtually impossible on jacketed lines or double-braids without destroying the rope. Rope travel due to load Due to force WITHOUT CHAFE GEAR (HMPE ON METAL) Friction caused by poorly maintained deck hardware surfaces causes both external abrasion to surface strands and abrasion to internal strands by creating relative movement between the fibers in the rope. Rope travel due to load Due to force PROTECTING YOUR INVESTMENT A. ROPE SELECTION SATURN-12 EXTENDS SERVICE LIFE BY 15 20% WITH CHAFE GEAR (HMPE ON HMPE) External abrasion is primarily limited to the chafe gear itself, and the relative movement of internal and external fibers is greatly reduced or eliminated. Samson s Research and Development team set out to find a way to mitigate the effects of abrasion to extend the service life of synthetic rope. The best way to start was to build a better rope. Saturn-12 was developed using a proprietary coating applied to the rope s yarns during the stranding process combined with the proven performance of a 12-strand rope made with 100% Dyneema. To evaluate new product performance, laboratory testing and computer modeling can only provide part of the data. Saturn-12 needed to be tested in the field in real working conditions. In 2009, Samson solicited the assistance of longtime customer, G&H Towing Company of Texas, to partner with us to field test Saturn-12. The field trial consisted of: > 11 tractor tugs outfitted with Saturn-12 pendants > Data compiled from 35 HMPE ropes from two manufacturers > Lines used in more than 27,000 operations > After service, all ropes were then tested to destruction to assess the residual strength External abrasion without protection External abrasion with chafe protection Internal abrasion without protection Internal abrasion with chafe protection Saturn-12 proved to have 92% residual strength after 2,240 hours in service. THE RESULTS: Saturn-12 showed a significant increase in the residual strength of the rope measured throughout its service life (see figure A); more tows, safer tows, and longer service life. Consistent with Samson s drive for continuous improvement, Samson made Saturn-12 even better. It s proprietary coating has been improved for increased UV protection, and Saturn-12 is now made with Dyneema SK78 fiber, the next generation in HMPE fiber, which improves cyclic bend performance and mitigates creep in long-term load situations. 11

13 PROTECTING YOUR INVESTMENT continued B. SURFACE PREPARATION There are no synthetic lines that will perform to their maximum capability with poorly maintained deck equipment. Ignoring surface conditions can be a costly mistake, especially if wire ropes were used previously. Proper surface preparation prior to synthetic line installation can extend the life of your lines dramatically. > Scored and rusty surfaces need to be faired and repaired. > Winch drums, flanges, bullnose and chocks in the rope s path need to be inspected and resurfaced if necessary. Once the surfaces are smooth and the new ropes are installed, only minimal maintenance is required to keep the surfaces in good order. Once your towline is hauled through the ship's chocks you've lost complete control over the surface conditions it is subjected to. C. CHAFE GEAR IMPROVING THE NUMBERS EVEN MORE Once the messenger line hauls your towline through the ship s chocks, you ve lost control over the surface conditions your pendant has to withstand. Conditions your line encounters can be affected significantly by a ship s poorly maintained, scored and rusty chocks, fairleads, capstans, and bollards. The pendants and end of the mainline that are often exposed to conditions such as these are best protected with chafe gear. Properly selected chafe gear protects the strength member within, dramatically extending the service life of the towing system. It is far less expensive to replace chafe gear than it is to replace the pendant. Over the life of the tow system, this simple addition adds real, measurable value (see figure A on page 10). SELECTING PRO CHAFE GEAR There are many types of chafe gear, from relatively simple and inexpensive fabric options to those made with HMPE fiber that provide the utmost in protection. For protection against moderate abrasion, an open-braid construction is appropriate such as Dynalene. This spliced-in chafe product provides great protection to the rope while allowing easy inspection of the rope s external and internal fiber conditions. Since Dynalene is made of 100% Dyneema, it is extremely abrasion resistant, lightweight, and easy to repair in the field. For more robust protection where frequent handling around abrasive surfaces puts a premium on rope protection and snag resistance, DC Gard fits the bill. It has a tightly woven construction that completely covers the rope and is made of 100% Dyneema. Also available is TC Gard, which has the same construction but is made with Technora fiber for use where extreme heat is an issue. Samson chafe protection products are perfectly suited to combat the causes of cutting and abrasion encountered in ship-assist operations. Chafe gear extends the life of your investment, adding real, measurable value. More information on surface preparation and chafe protection is available online at under the Resources and Literature menu. 13

14 EXTENDING SERVICE LIFE EXTENDING SERVICE LIFE THROUGH CONSTANT CARE Getting the most out of your high-performance synthetic towing system is relatively easy as long as proper care and consideration are part of your everyday operation. Below are key activities that should be addressed to prevent line failure. Photo Brian Gauvin 1 KEYS TO PREVENT LINE FAILURE AND EXTEND SERVICE LIFE 1. Proper surface preparation, maintenance, and routine inspection A 300-microinch finish (7.62 microns) for all deck hardware that comes in contact with the rope is recommended. As long as synthetic ropes are used exclusively, resurfacing won t be required very often Install lines under proper tension A minimum load of lb (45 kg 90 kg)* is recommended. Install the first three layers on winches under tension. Crisscross subsequent layers to minimize line-diving Prevent or remove all twist from the tow line Twist can significantly shorten rope life by causing unbalanced loading of the rope s strands. When observed, remove twist as soon as possible it s as simple as laying the rope out, and, working from the winch towards the rope s end, twisting the rope in the opposite direction until the strand crowns are straight. Use of a swivel can help prevent (or minimize) twist generated from messenger lines 4 4. Always use chafe protection Chafe protection should be used on all high-contact areas of the line. The pendant should be protected from the point where it passes through the chocks to the end of the eye. If the bullnose or fairlead is rough, chafe gear should be placed there. 14

15 5. Inspect the ship s chocks As you re making the approach, look for the best surface conditions for the rope. If there s a better option, it should be discussed with the pilot. It s best to avoid roller chocks in general, and any chocks that are heavily scored from use with wire ropes Keep a proper working angle on the rope during the maneuver The angle of the rope measured from the horizontal determines the load on the rope. In general, a short scope on the rope causes a higher working angle on the rope and can dramatically increase the load on the rope. Whenever possible, use the longest scope the towing situation will safely allow. 6 Photo Brian Gauvin If the tug exerts a force of 50 tons at an angle of 20 degrees, the actual force on the line is 50 x 1.06 = 53.0 tons Bollard Pull = 50 tons Bollard Pull at 45 angle 50 x 1.41 = 70.5 tons ANGLE LOAD MULTIPLIER The angle of the rope determines the load on the rope. Whenever possible, use the longest scope the towing situation will safely allow. 7 Photo Brian Gauvin 7. Line inspection Inspecting lines after each use is one of the best ways to mitigate problems. Implementing a consistent protocol for crew to follow will pay off. See page 16 for inspection guidelines and tools available from Samson. 8. Documentation and residual strength testing In order to establish retirement criteria for your vessel, documenting information about your lines and completing residual strength testing is a necessary step. See page 17 for more on Samson s residual test programs. 8 15

16 Regular inspections and repair as needed will extend the working life of highperformance lines. INSPECTION GUIDELINES AND RESIDUAL STRENGTH TESTING 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: Examples included herein are the most common types of wear and damage to rope and are for illustration purposes only. COMPRESSION REPAIR PULLED STRAND REPAIR WHAT > Visible sheen > Stiffness reduced by flexing the rope > Not to be confused with melting > Often seen on winch drums CAUSE > Fiber molding itself to the contact surface under a radial load CORRECTIVE ACTION Flex the rope to remove compression. MELTED OR GLAZED REPAIR OR RETIRE WHAT > Strand pulled away from the rest of the rope > Is not cut or otherwise damaged CAUSE > Snagging on equipment or surfaces CORRECTIVE ACTION Work back into the rope. DISCOLORATION REPAIR OR RETIRE Request a copy of this handy reference tool from your Samson representative, or download the Samson app. INCONSISTENT DIAMETER REPAIR OR RETIRE WHAT > Fused fibers > Visibly charred and melted fibers, yarns, and/or strands > Extreme stiffness > Unchanged by flexing CAUSE > Exposure to excessive heat, shock load, or a sustained high load CORRECTIVE ACTION If possible, remove affected section and re-splice with a standard end-for-end splice. If re-splicing is not possible, retire the rope. CUT STRANDS REPAIR OR RETIRE WHAT > 12-STRANDS: Two or more cut strands in proximity 8-STRANDS / 3-STRANDS: One or more cut strands CAUSE > Abrasion > Sharp edges and surfaces CORRECTIVE ACTION If possible, remove affected section and re-splice with a standard end-for-end splice. If re-splicing is not possible, retire the rope. WHAT > Fused fibers > Brittle fibers > Stiffness CAUSE > Chemical contamination CORRECTIVE ACTION If possible, remove affected section and re-splice with a standard end-for-end splice. If re-splicing is not possible, retire the rope. ABRASION REPAIR OR RETIRE WHAT > Broken filaments and yarns CAUSE > Abrasion > Sharp edges and surfaces > Broken internal strands CORRECTIVE ACTION Consult abrasion images* and rate internal/external abrasion level of rope. Evaluate rope based on its most damaged section. n Minimal strength loss (continue use) n Significant strength loss (consult Samson) n Severe strength loss (retire rope) WHAT > Flat areas > Lumps and bumps CAUSE > Broken internal strands > Shock loading CORRECTIVE ACTION If possible, remove affected section and re-splice with a standard end-for-end splice. If re-splicing is not possible, retire the rope. Inspection and Retirement Quick Reference Tool** During your inspection you must consider the following before deciding to repair (when possible), downgrade, or retire your rope: > The length of the rope; > the time it has been in service; > the type of work it does; > where the damage is, and; > the extent of the damage. In general, it is recommended to: > Repair the rope if the observed damage is in localized areas. > Retire the rope if the damage is over extended areas. **REFERENCES Cordage Institute International, International Guideline CI , Fiber-Rope Inspection and Retirement Criteria: Guidelines to Enhance Durability and the Safer Use of Rope, *Refer to images on Inspection & Retirement Pocket Guide or Samson app

22 TUG MANEUVERING LINE PENDANTS To ensure maximum service life of tug assist and maneuvering lines, Samson recommends the use of a Saturn-12 single-leg or strop pendant to take the abuse of rough undressed chocks and bitts aboard the assisted vessel SINGLE-LEG The industry standard overall length for a single-leg pendant is feet ( meters) with a 1 3 foot soft eye, for mating to the mainline, and a 5 7 foot soft eye for the shipboard connection. Hardware and chafe protection can be added upon request. STROP The industry standard overall length for a strop pendant is feet ( meters). Strop strength is 1.6x the single-leg rope strengths. Strop configurations can be adjusted to share the wear over the length of the pendant. Hardware, chafe protection, and additional seizing can be added upon request.

TUG PENDANT CONNECTIONS Samson recommends the use of an eye-to-eye connection to attach the mainline to the pendant. Pendants can also be connected to the mainline by way of a cow-hitch connection (also known as "chain link" or "spectacle" connection). EYE-TO-EYE CONNECTION The eye-to-eye connection provides a suitable method of joining two ropes of similar diameter without the use of thimbles or other hardware. It yields 90 to 100% strength efficiency. AmSteel -Blue mainline with eye-to-eye connection to AmSteel -Blue pendant. COW-HITCH CONNECTION The cow-hitch connection provides a suitable method of joining two ropes of similar diameter without the use of thimbles or other hardware. It yields approximately 85% strength efficiency. AmSteel -Blue cow hitched to AmSteel -Blue pendant. Cow-Hitch Connection 22
