Commercial diving industry

Siieg's engineering started with the underwater constructing and salvage of ships also the inspections of floating vessels. Underneath you some pictures of siiegs founder Boudewijn Sanders at work as an underwater engineer. 
In present times we still manage underwater constrauction projects. like bridge building, marina projects ect ect

Saturation diver working on the USS Monitor wreck at 70 m (230 ft) depth.
Saturation diver conducts deep sea salvage operations.Saturation diving is a diving technique that allows divers to avoid the deadly effects of "the bends" so they can work at great depth for long periods of time.

"Saturation" refers to the fact that the diver's tissues have absorbed the maximum partial pressure of gas possible for that depth due to the diver being exposed to breathing gas at that pressure for prolonged periods. This is significant because once the tissues become saturated, the time to ascend from depth, to decompress safely, will not increase with further exposure.
