There can be various reasons to carry out an inspection. Some examples of this can be found in the explanation below:

With the great diversity of water-related objects, works of art and constructions, as well as shipping, we encounter many types of damage images.

Examples include:

  • mechanical damage;
  • corrosion or other chemical reaction;
  • subsidence or worse collapse of building parts or structures;
  • leakage of structural parts;
  • power loss;

In the event of such (consequential) damage, an inspection may be able to answer questions such as: What is the cause of the damage?; What is the current state of the underwater parts?; Are there any further risks? (e.g. consequential damages)

In the management of objects, laws and regulations often set requirements for the conservation and/or residual life determination. For example, the NEN 6710 in which the requirements that a construction must meet during the use phase are laid down. Inspections of the building components play an important role in this. PRO-SEA can support this with a diving inspection of the parts located on and underwater.

In summary, in the event of damage (whether or not caused by third parties), maintenance issues and also condition inspections, PRO-SEA is the right partner. With various inspection options at our disposal, we can be used for a wide range of constructions, works of art and even complete objects. Below are some examples of our field of work already:

– Quay construction and foundations;

– Works of art, such as: Locks, bridges, barriers, etc.;

– pumping stations;

– shipping;

– port area

– Industrial installations and inlets;

– and much more!


Visual Inspection

With high-quality audio and video equipment, the observations can be recorded during inspection and, if desired, followed by you ‘live’ on location. Depending on the circumstances, both divers and/or an ROV can be deployed. In addition, the results can be summarised for you in a clear report, possibly supported by e.g. measurement data, an inspection drawing, photo and/or video attachment.

NDT (non-destructive testing)
This involves research without weakening the object to be examined or constructively. In addition to the visual inspection described earlier, there are also other inspection options, such as:

Ultrasonic measurementsThickness measurements of metals, such as sheet piling, ship’s hull, storage tanks.

Eddy current Detection of material defects and/or damage under the metal surface, often used for dynamically loaded parts where e.g. metal fatigue can occur or for detecting production defects.

Magnetic researchDetection of cracks in the surface in ferrous metals such as structural steel)

SamplingMaterial extraction for further (laboratory) research. e.g. wood drilling samples from foundation piles, soil sampling, sampling, masonry/concrete core drilling.

Determining construction construction, dimensions and measuring
With digitization, data and drawings of structures are often faster and easier to access. Yet it still happens regularly that these are not available. For example, these have been lost, not up to date or perhaps not previously digitized. We can also provide a solution for this. Even in poor or no visibility conditions, it is often possible to determine and measure underwater structures.
