On board a 330 metre long pipe-laying vessel, pipelines are blasted before they go into the sea. Together with the client, Straaltechniek International developed a blasting installation that does this dust-free, on board and on the open sea.

The challenge

The client is a leading, globally operating company that designs and manufactures pipelines for the oil and gas industry, specialising in deep water. Pipe sections are delivered by ship and processed on board the pipe-laying vessel: blasting, welding, blasting again and coating. The complete pipeline then leaves the stern of the vessel and is laid on the seabed.

Blasting on a ship calls for an installation that does not spread dust and keeps running reliably in a continuous production process on the open sea.

The solution

Working closely with the client’s project team, we developed an installation for the dust-free blasting of pipelines on board. The blasting units are a crucial step in the process: they prepare the steel for the coating that protects the pipeline against seawater.

The result

The quality has amply proven itself: we have now supplied this company with more than 30 units, spread across several vessels. In this way, our blasting solutions contribute to the global energy supply.
