Hyperbaric, Dry & Wet Welding
Welding processes have become increasingly important in almost all manufacturing industries and structural applications. Although a large number of techniques are available for welding in the atmosphere, many of these techniques cannot be applied in offshore and marine applications where the presence of water is of significant concern.
In this regard, it is relevant to note that a great majority of offshore repairing and surfacing work is carried out at a relatively shallow depth in the region that is intermittently covered by the water known as the splash zone. Though numerically, most ship repair and welding jobs are carried out at a shallow depth, the most technologically challenging task is repairing at greater depths, considering the presence of pipelines and potential failures.
The advantages of underwater dry or wet weldings are primarily of an economic nature, mainly because underwater welding in marine maintenance and repair jobs bypasses the need to pull the structure out of the sea which saves valuable time and dry docking costs. It is also an essential technique for emergency repairs which allows the damaged structure to be safely transported to dry facilities for permanent repair or scrapping.
DELTA GROUP has completed a number of projects on subsea welding, repairing platforms or underwater pipelines and subsea structures. We can repair all kinds of damage underwater, which is a more efficient way than repairing in a dry dock. We can work in all harbours in the world and are available 24/7.
