Inspection

We offer a comprehensive engineer led survey and evaluation of all structure types both above and below the waterline, whether they are aging and in need of repair or a new build. Our inspections can incorporate dimensional surveys, Non-Destructive Testing, material sampling, video & low-light photography to produce high quality assessment and reports.

Corrosion Control

Through our diving projects the team has gained extensive knowledge of the effects of corrosion of submerged and semi-submerged structures and the methods for controlling this damage. Our divers are able to detect microbiologically influenced corrosion (MIC) and accelerated low-water corrosion (ALWC) that affects a large amount of marine structures.

Following the identification our team can put together a quality package for the control of this process as well as giving advice on both above water and underwater installation.
