The C1-16UL incorporates several groundbreaking innovations, including a subsea-grade aluminium frame replacing traditional steel construction and a high-torque direct-drive hydraulic motor which has eliminated the need for a gearbox without sacrificing performance.
The C1-16UL employs a sophisticated single-clamp system that provides equivalent stability while reducing weight and complexity. A revolutionary modular buoyancy system allows fine-tuning for different operational environments, ensuring optimal stability and control across varying deployment conditions.
Nick McNally added: “The C1-16UL has been designed to accommodate multiple deployment methodologies. The tool can be deployed in a subsea basket, via our own purpose-built deployment frame, or attached directly to the front of an ROV - a configuration successfully implemented on a recent project in Brazil.
“The versatility of the C1-16UL allows for cuts to be made in any orientation, providing unprecedented flexibility in various operational scenarios. This adaptability, combined with its lightweight design, opens up entirely new possibilities for subsea intervention work.”
Decom said the C1-16UL addresses critical limitations in existing subsea cutting technology, where weight and size constraints made traditional tools less suited for deployment in confined subsea environments or attached to an ROV.
“We identified significant knowledge gaps that couldn’t be bridged by existing adaptations of conventional technology. The redesign of the cutting frame using subsea aluminium to reduce weight, the reconfiguration of hydraulic drive systems to enhance efficiency, and the integration of buoyancy control systems are hallmarks of Decom’s innovative approach to offering clients optimal cutting solutions.
“Experimental validation and iterative development that went well beyond routine engineering improvements has resulted is a tool that doesn’t just improve on existing solutions - it fundamentally changes what’s possible in subsea cutting operations.”
