Marine Decommissioning

Marine decommissioning and recycling of marine structures and vessels is a mammoth undertaking.
It not only requires extensive planning, experience, and expertise, it also requires specialist plant and an appropriate location to carry out the marine decommissioning process.

Brown and Mason not only meet all of these requirements, we surpass them. We have over 50 years of experience, with teams of qualified experts and a fleet of plant capable of dealing with all marine decommissioning projects.

Marine Decommissioning Service

Brown and Mason’s marine decommissioning services are becoming increasingly significant as numerous sea-based assets such as oil rigs and platforms approach the end of their service life.
We work with various ports which boast incredible facilities to accommodate safe marine decommissioning, all perfectly placed for decommissioning marine structures throughout the surrounding ocean, including the structure-heavy North Sea.

But don’t think that we are limited to operating just in the North Sea – we already work in many countries throughout the world. We take pride in our ability to resource contracts of any size and in any location on the globe, however complex the logistics.

We provide a bespoke service on each and every marine decommissioning project – the complications and size of marine based vessels means each one is truly unique.
