Marine Rope Design and Analysis
TTI – Comprehensive Rope and Cable Consultancy Services
At TTI, we offer end-to-end consultancy in the specialised field of ropes and cables. With expertise spanning selection, design, installation, usage, inspection, and retirement, we ensure that every phase of your rope application is optimized for performance and reliability.
Selecting the wrong rope material or construction can lead to costly delays, premature failures, and compromised safety. That’s why we focus on getting it right the first time. Rope design is a sophisticated engineering task involving complex interactions between multiple helices, which influence strength, elongation, and overall performance in various applications. Our in-depth understanding allows us to address these challenges with precision.
TTI works with both fibre and steel wire ropes, selecting the ideal construction and material type tailored to each specific task. Utilising proprietary tools like the Fibre Rope Modeller (FRM), we can accurately design custom ropes and assess their fatigue characteristics, ensuring longevity and efficiency.
Trust TTI to help you avoid costly errors and to deliver solutions that meet your technical and operational requirements.
Rope Manufacturing
Maintaining precise rope geometry and consistent tension is essential for high-quality rope production. Different manufacturing machines influence these factors in varying ways, potentially impacting rope performance. TTI provides expert guidance on the optimal machinery and setup to use—balancing productivity, quality, and performance.
Rope Installation
Proper rope installation is a critical step in the overall system. If performed poorly or under adverse conditions, it can damage the rope and result in equipment failure, costly delays, or even loss. TTI brings extensive experience to this process, offering both the development of detailed installation procedures and on-site supervision. This service is particularly valuable in new or untested applications.
Rope Lifetime
Determining the actual lifetime of a rope remains a challenge. As a result, ropes are often replaced too early—wasting resources—or too late, which can lead to equipment damage or serious accidents. There is no simple solution due to the many variables affecting rope life. However, TTI has made significant advancements through the development of Optilife Rope Monitoring, a proprietary software-driven system. Designed for demanding applications like mooring, this system tracks rope load and calculates life loss during each tension cycle. Once the rope reaches its predetermined end of life, the system signals the need for replacement. The technology can also be adapted for other uses, such as scenarios where the rope passes over sheaves.
