The Global Standard in Mooring Chain Severance
In the high-stakes world of offshore energy, mooring chain severance isn't just about making a cut — it's about protecting your schedule and your assets.
While Decom Engineering is a recognised leader in decommissioning, our specialised subsea Chopsaws are becoming the standard for offshore installation and construction campaigns worldwide.
When high-tension mooring lines need to be severed, we deliver the speed, safety, and engineering expertise to keep your campaign on schedule and under budget.
Standard cutting tools often struggle with shifting loads. Our Chopsaws are specifically engineered to sever mooring chains while they remain under large amounts of tension — a critical capability for installation and maintenance projects where chain stability is not guaranteed.

Innovation That Eliminates Risk
We take on the safety challenges that other industry suppliers decline. Every solution we engineer puts your crew further from harm and your project closer to completion.
Zero-Drop Safety
When a major client faced the critical risk of dropped objects during severance, we designed and engineered a bespoke faux link clamp system from scratch to solve that specific operational challenge. These custom retention clamps securely hold severed half-links in place — a solution other suppliers couldn't provide.
Crane-Free Deployment
Custom ROV skids allow tools to be deployed without a crane, increasing operational flexibility and saving critical vessel time on every campaign.
Exceptional Blade Life
100% success rate to date. Multiple cuts per blade with 5-minute blade changes — minimising costly offshore downtime and keeping your campaign on schedule.
Global Reliability You Can Trust
With over 150 projects completed, we have the global footprint and technical authority to support your next campaign — including Jones Act compliant operations in US waters.
Maximise your vessel time and cut your project costs. Whether it's a rapid decommissioning campaign or a complex new installation, Decom Engineering delivers.
