Heavy Lift Sling Market
Dominated by wire rope slings because of
Traditional use Engineering in lifts Excellent performance Precision length tolerances No stretch Certification standards Reliability Local global access Strengths up to 10,000 Te
But wire rope slings can provide problems too!
HeavyInflexible Rust and corrosion Storage Handling and rigging injuries
Wire rope lifting slings
High operational use costs Rigging time and manpower needed Difficult to use in offshore remote locations and varying weather states Extra equipment needed to rig Transportation costs Possible “marring” of item being lifted
Light weight High modulus Excellent tension
fatigue Over-sheave fatigue
life good at low rates and loads (can exceed wire)
Torque-free Does not corrode Strength equal to
wire on a per size basis
Very heavy High modulus Good to excellent
tension fatigue resistance
Good over-sheave fatigue resistance
Heat tolerant Prone to corrosion Require periodic
lubrication

High modulus synthetic fibers in slings
Cortland companies specialize in the design, manufacture and use of modern high modulus synthetic fibers such as
1.Plasma HMPE (High Modulus PolyEthylene)2.Aramids: Technora, Kevlar3.LCPs (Liquid Crystal Polymers); Vectran
Our knowledge of these fibers allows us to choose and propose the best fiber rope or Selantic round sling for your lift.
HMPE Synthetic Fibre Ropes
High Modulus PolyEthylene (HMPE) synthetic fibre ropes have become the most popular synthetic rope in wire rope replacements
Value Proposition:1/7th the weight of a comparable strength wire Can replace size for size wire rope Flexible torque-free braided constructions Most cut and abrasion resistant synthetic fiber in rope Impervious to most environmental conditions Allow operators to conduct operations faster and safer Typically provide longer service life
HMPE fiber in ropes and slings
Allows marine operators to save money through faster and safer operations
Tug
1. Fewer crew members need lightweight strong rope in diameters they can handle1. Fewer rope handling injuries
2. Proven global track record on high horsepower tractor tugs1. Handle indirect maneuvers2. Long service life3. Works in cold or hot weather with no problems4. Most leading global tug companies have converted
3. Faster line “make-up” and retrieval4. Non-jacketed HMPE ropes are easy to inspect and repair
HMPE fiber in ropes and slings
Mooring
1. Fewer crew members need lightweight strong rope in diameters they can handle1. Fewer rope handling injuries during mooring process2. Fast mooring times; reduction of up to 2/3rds time
2. Proven global track record on leading oil and gas carriers1. Chevron, Shell, BP, BG, etc.2. Long service life3. Works in cold or hot weather with no problems
3. Non-jacketed HMPE ropes are easy to inspect and repair4. Long service life – up to 3 times or more that of wire rope
Synthetic fiber slings offer solutions
Cortland offers two typesof HMPE fiber slings
1. Selantic round slings
2. Puget Sound Rope slings
Both offer advantages inlifting over wire rope
Heavy lift Selantic slings
What we can do at Cortland / Selantic
Make specialty round slings up to 2000 Te MBL from high modulus synthetic fibers
Selantic brand
1. Industry and application experience in lifting
2. Well respected by key customers for product and engineering services
3. Ability to design with customers on both slings and hardware
4. Innovative product offerings and protective coverings
5. Rapid manufacturing6. Well known by DNV
Cortland Sling Solution goals
1. Work with customers to provide lightest weight products to replace wire rope in lifting1. Synthetic fiber lifting sling products2. Specialty compliant hardware3. Reliable performance values on
products 4. Compliance with safe lifting standards
and procedures5. Guidelines to safe use, inspection and
repair of sling products
Heavy lift Plasma Rope slings
What we can do at Courtland / PSR
Make vertical lift Plasma rope slings from up to 2233 Te in an eye-to-eye configuration or 3685 Te MBL in an endless grommet u
Puget Sound Rope Plasma Brand
Innovative patented HMPE product and construction (12x12) with growing global name-brand recognition
The largest 12 strand braider in the world – able to produce up to 200mm diameter 12 strand torque-free braids
Extensive testing to back Plasma and rope products We are currently testing 180mm
diameter Plasma 12 x 12 in Houston for a lifting job
PSR’s most popular rope - Plasma
• We take base HMPE fiber and put it through our patented secondary yarn process to increase strength through molecular alignment
• 12 x 1 construction from 1/8” – 1/1/2” dia.
• 12 x 12 construction from 1 5/8” diameter up
Patented Plasma rope
1. The patented Plasma process allows us1. Offer the highest strength
HMPE fiber rope2. Distinguishes ourselves from
people who sell “Dyneema rope”
3. Create new product from “yarn-up”
Rope Design and Construction
Patented 12 x 12 rope
construction
12 x 12 braided construction
• Reduces abrasion• Reduces compressive
damage• Easiest to splice• Easiest to inspect • If damaged, fast/simple
field repairs• Strands removable for
analysis
Cortland / PSR 12 x 12 construction
12 x 12 construction advantages
• Better bend fatigue due to construction
• Better profile retention than 12 x 1 design
• Strand repair• Long continuous lengths
due to less braider splices

Plasma rope sling standards - bending
If bending is a consideration for the sling, the angle of the lift on the sling and the size of the pin or object being lifted can seriously effect the MBL of the Lifting Sling. Angles and D: d ratio, (described as the ratio of the diameter around which the sling is bent divided by the sling body diameter of a single leg sling, or the component rope diameter in a multi-part sling), must be factored in the determination of a DF(Design Factor) to create a WLL (Work Load Limit)
D = the diameter of the bend and d = the nominal diameter of the sling.
Plasma rope sling standards - bending
The D: d ratio has a significant effect on the rated capacity of the sling when the sling is wrapped or bent around the object being lifted. Whenever a rope is bent around a diameter, the strength of the rope is decreased Synthetic rope and round slings offer a significant advantage over steel wire ropes in this bending factor due to many factors including better flex fatigue performance: e.g. wire rope slings typically need a D:d bend ratio of 18:1 or greater.
Synthetic fiber rope slings, depending on the fiber used, necessitate a typical D: d ratio as low as 2:1 – 8:1.
