Level I - General Visual Inspection:
The Level I visual inspection confirms as-built structural plans and detects obvious major damage or deterioration due to collisions, severe corrosion, or extensive biological growth and attack.
 
Level II - Close-Up Visual Inspection:
A complete, detailed investigation of selected components or critical areas of the structure, directed toward detecting and describing damaged or deteriorated areas that may be hidden by surface biofouling.
 
Level III - Highly Detailed Inspection:
This level of inspection is primarily designed to provide data that can be used to perform a structural assessment and will often require the use of Non-destructive Testing (NDT) techniques. The procedures are conducted to detect hidden or imminent damage, loss in cross-sectional area, and material homogeneity.

​

Anode - Anode Survey is to evaluate the anode condition, percentage remanning or completely depleted. if needed we can replace or install new set of Anodes on the structure.

​

Anode is a material made by zinc, aluminium alloy which prevent the iron to get corrosion to keep the steel life longer underwater. There is 2 kind of anode available a impress current anode and sacrificial anode. most of the small structure use sacrificial anode and that need to replace ones they get sacrificed to protection the metal underwater.
