Quality Management
Our quality inspection services for shipbuilding and offshore projects are carried out by experienced inspectors certified by international institutions, available for every production stage from factory acceptance test to commissioning and hook up. Also we carry out In-process inspection, which shortens the inspection period and preemptively removes possible quality issues.
