Decom Engineering (Decom) has invested more than $1.2 million to develop its largest Chopsaw to date in response to client demand for larger sized subsea pipe-cutting capability.

The C1-46 Chopsaw has been designed to be useable in water depths of up to 2,000 meters and can cut pipes up to 46” of a wide range of materials in any orientation.

Multiple lifting points located around the tool allow a versatile angle of deployment and an array of cuts can be completed whilst subsea or held in wet storage, without returning to the surface.

Currently the saw is deployed on its first project on behalf of a global energy company on a UK North Sea workscope, which involves cutting large surface laid pipelines (36") with 57mm concrete coating, along with other large pipelines.

“The saw clamps are designed to penetrate into the sea bed/sediment and to minimise the need for trenching. We are excited to see the C1-46 perform successfully on this North Sea project and we will take the lessons learned to refine and improve the product and its operational capabilities.” said Decom Engineering managing director, Sean Conway
