C1-46 Chopsaw
The C1-46 Chopsaw is a heavy-duty subsea cutting solution developed in response to client-led requirements, engineered to cut large OD pipelines up to 46” in diameter, including concrete-coated pipelines and steel rebar. Designed to address complex offshore cutting challenges, the tool sets new standards in large-diameter subsea cutting applications.
Built with DNV certification, the C1-46 incorporates a robust landing frame for safe and stable operation, along with rapidly configurable clamping options to suit varying project requirements. Hot stab integration supports efficient operation, while segmented blade tip technology reduces deck handling and improves cutting efficiency during demanding offshore campaigns.
