The Cortland and Tufropes brands. Designing smarter ways to work.
Cortland International is a designer, manufacturer, and supplier of technologically advanced ropes, nets, slings, tethers, and strength members serving clients worldwide. Today, with more than four decades of experience, the company is the combined global strength of the Cortland and Tufropes brands. Together as Cortland International, we provide exceptional understanding and insight into the most difficult synthetic rope and netting applications.
Engineering excellence with large-scale, world-class manufacturing.
Pushing boundaries. Lifting barriers. Working together.
Every day we work closely with our customers to understand their application requirements and build unique solutions that ensure success. Let’s see how we can push the boundaries of your industry.
“We have used your rigging products in the industry for a long time and are a firm believer in the quality Cortland provides. We prefer your products over others due to the amount of technical information you have available to end users, specifically the Bending Guidance reduction factor with an inadequate D:d ratio. This is what we would like to teach our clients and showcase the exceptional products and data your team offers.”

Innovative, Successful Solutions
The people of Cortland International are passionate, collaborative problem solvers who operate in a culture of confidentiality. All information we share is protected from the very first meeting to final delivery. We’ve been allowed to share what we did for the following customers. Imagine what we could do with you.
Vertical positioning of subsea buoyant structures is very different from horizontal positioning of floating structures like FPSOs. Tethers require a design life greater than 20 years to battle corrosion, marine growth and particle ingress, product design and material choices are critical to success. Cortland’s Selantic® Tethers are field-proven for such applications due to their low creep rate (non-reversible elongation), and long-term fatigue performance. Cortland developed and patented an ROV-friendly system for connection/disconnection of Selantic® tethers.
When heavy machinery such as articulated trucks or wheeled excavators become stuck or inoperable, shackle and block-and-pulley recovery solutions are standard. Together with Caterpillar Inc., Cortland developed and patented a recovery/towing assembly that is lightweight, durable, and improves personnel safety. The Cat® synthetic rope recovery and towing system is the only approved system designed to replace heavy chain and wire rope.
Cortland’s patented technology of Braid Optimized for Bending (BOB®) rope construction was developed specifically for use where ropes cycle continuously back-and-forth across sheave applications. The concept was proven in 2006 when used aboard the first successful full Active Heave Compensated deepwater rope traction winch used to deploy equipment to a depth of 2,700 meters.
Cortland engineers partnered with Applied Fiber to solve the challenge of large rope socketed terminations, and achieved 100% rated rope efficiency in a compact package. The termination process enabled the production of terminated ropes with length tolerances to millimeter precision, simply not achievable with standard splicing methods. This introduced many new termination options for synthetic fiber rope, including multi-point inspection, overload indication, interchangeable and reusable connections, and integrated hardware.
Traditional rigging is very large, limiting the ‘height under hook’ of installation vessels, and making the systems heavy and difficult to handle. Cortland developed and patented a synthetic solution for performing subsea load transfer operations from crane hook to structure. The solution eliminates steel components from hook to structure (tri-plate and associated shackles), reducing weight, size, installation time, and potentially overall cost of the rigging system without jeopardizing the required factor of safety (FOS).
