The need for the testing and evaluating rope
performance
In specific high demand applications the rope performance and
service life is a critical parameter and may have a considerable
impact on operation, maintenance and production costs

Installation
• Correct installation of the rope will have a positive effect on wire rope performance
• Poor installation of the rope will have a negative effect on the rope performance.
Grooved drum systems aid good spooling
![Page 49: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/49.jpg)
Installation
• Correct installation of the rope will have a positive effect on wire rope performance
• Apply back tension to the rope during installation:– at least 2% of the Minimum Breaking Load– or up to 25% of working tension (as training load)
• Training of large diameter complex rope constructions:– deploy in deep water – Cycle to remove construction effects
• Training the rope to optimise rope performance• Reflect back to rope selection
– Define dimensional tolerance– Understand compressibility: Axial and radial
![Page 50: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/50.jpg)
Lifetime Integrity Methodology
The following five methodologies can be applied to provide wire rope integrity assurance:
• automatic discard (replacement) after a set period, • thorough examination and inspection;• non‐destructive examination;• destructive tensile testing; and• a range of post‐retirement activities which will provide feed‐back into the
integrity management system.

Integrity Methodology ‐ Discard
The following five methodologies can be applied to provide wire rope integrity assurance:
• automatic discard (replacement) after a set period, • thorough examination and inspection;• non‐destructive examination;• destructive tensile testing; and• a range of post‐retirement activities which will provide feed‐back into the
integrity management system.

Discard
• International Standard ISO 4309• Considers the application:
– Bend fatigue driven– Surface contact damage
• Considers the rope construction• Training & Competence
![Page 59: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/59.jpg)
Risk Management
• Single Broken Wire:– Probability = high– Impact = low
• Broken rope – Probability = low– Impact = high
Rope integrity = Confidence in equipment for reliable operations.
Risk = probability x impact
• Multiple Broken Wires in a similar location:– Make probability of identification – high– Repair / Replace– Prevent– Make probability of it becoming a failure = low
• Maintenance & competence = reduction in Risk
![Page 60: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/60.jpg)
Summary
• Rope Integrity Management is Risk Management• Increased Competence & Maintenance reduces risk.• Use all the tools practically available. • Feed back !• Objective to ensure confidence in rope & equipment for
reliable, safe, economic operations.

MRT is an additional tool for rope testing
Inner damages can be determined quantitatively
MRT + VT are necessary for the determination of the
deterioration
Information about service time and periodic MRT are
required for a lifetime assessment

Speaker
Arnold Free, CMLabs / Vortex, Montreal, CALecture: Design and implementation of effective simulation‐based training
curriculum for offshore lift crew trainingBackground: He has earned his Ph.D. in Engineering from Cambridge University,
UK and draws on nearly 30 years of engineering and software experience in simulation, training and operations planning. He has helped organizations navigate how they use simulation technology to improve safety and better business practices
![Page 118: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/118.jpg)
The work is simulated. The skills are real.
![Page 119: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/119.jpg)
If you believe training is expensive.
Try ignorance!
![Page 120: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/120.jpg)
An evidence-based approach to simulation-driven lift planning and
learning.
A brief look at how simulation can transform processes in the offshore lift industry.
![Page 121: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/121.jpg)
How do we create effective learning organizations?
Look at the empirical evidence.
![Page 122: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/122.jpg)
Myth.
People learn through different training styles.
![Page 123: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/123.jpg)
Evidence.
There is no evidence that we learn through different styles (auditory,
visual, etc).
There is strong evidence we learn by doing.
![Page 124: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/124.jpg)
Myth.
We learn best through formal/structured programs.
![Page 125: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/125.jpg)
Evidence.
There is no evidence that we best learn through formal training
methods.
There is strong evidence that skills retention is better with informal
and repetitive learning.
![Page 126: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/126.jpg)
Myth.
Information = knowledge.
![Page 127: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/127.jpg)
Evidence.
Learning methods that provide information through presentations (with
instructor or via elearning) are less effective – telling is not learning.
There is strong evidence that learning effectiveness is much higher when
the student is actively engaged in problem solving.
![Page 128: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/128.jpg)
Myth.
Practice makes perfect.
![Page 129: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/129.jpg)
Evidence.
Practice is important when learning skills, but practice alone is not
what really matters and practicing incorrect behaviour can have a
very negative impact.
What makes the difference to effective learning is planning, doing
and corrective feedback.
![Page 130: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/130.jpg)

Is simulation-based training effective?
The evidence is very clearRecent study in several industries – simulation‐based training was found to be effective and recommended for on‐going or expanded use in all casesRecent Vortex survey of operators and instructors (about 300 individuals surveyed) who had used simulators
87% of instructors stated that simulation based training was very effective at skills development 75% of operators stated they would find it extremely useful to practice in a simulator before performing a lift or learning new procedures
![Page 143: Proceedings Thursday 14th April](https://reader030.vdocument.in/reader030/viewer/2022020208/568bd56b1a28ab203498618e/html5/thumbnails/143.jpg)
