UWILD

Inspection in Lieu of Dry-Docking

Also called bottom surveys, general visual inspections or in-water surveys. Divers inspect during normal cargo operations, so you avoid downtime, extra travel and expensive dry-docking.

We are approved to inspect all ship types, including jack-up rigs and semi-submersible platforms.
