126Te tensioner delivered to Oceaneering International Inc.

The 4-track system will strengthen the contractor's flex-lay capabilities.

The tensioner was designed to integrate with Oceaneering's multi-service vessels to support installation and recovery of flexible products at higher top tensions and in deeper waters. It will work alongside Oceaneering's 800-tonne electric Reel Drive System, also previously delivered by MDL.

The 126Te tensioner is a hydraulically driven, 4-track system designed for high-capacity product handling in offshore lay operations. It incorporates a single segment opening that pivots up to 130°, increasing the aperture for the loading and unloading of products, including larger terminations.

This design was developed in response to operational requirements discussed with Oceaneering and involved resolving several structural and control challenges while maintaining a compact system footprint.

The system provides 5m track contact length, increasing the range of product types it can accommodate by allowing load to be spread evenly across the product over a longer length for safer handling.

Engineered to operate at full capacity with a coefficient of friction as low as 0.07, the tensioner delivers high squeeze performance, extending its operating range and supporting a broader spectrum of product specifications.

Ramasay Keay, Projects Director at MDL, said:

"It's great to deliver another MDL system and further enable Oceaneering's operations, following the delivery of our most capable reel drive system previously.

"Assembled and commissioned at MDL's new facility, Maritime House, the unit underwent comprehensive testing on our purpose-built test bed. This enabled us to safely demonstrate the system's impressive capabilities in a controlled environment, providing the client with full confidence ahead of shipment to the US.

"The single-track opening was a technically challenging upgrade, but one we knew would bring real value to Oceaneering's operations. The system delivers greater operational flexibility while retaining its compact footprint and modular design.

"This project showcases how our engineering expertise, combined with Oceaneering's forward-thinking strategy, has delivered a fit-for-purpose solution tailored to both immediate project needs and long-term asset renewal.

"A testament to our modular technology, designed to adapt to client requirements, maximising operational flexibility while supporting efficient, future-proof energy developments."
