Quality Control of the coating on Commercial Vessels and Mega Yachts


The quality control (QC) of the coating on commercial vessels and mega yachts is a very important process to ensure both desired aesthetics and performance are achieved.

In fact, this importance is a reality for the whole marine sector, including new constructions and refits of ships, yachts, offshore, structures and accessories.

Obviously, coatings are very important for commercial vessels and mega yachts since they are exposed to a very corrosive environment. So, keeping it at the highest performance level is essential for the integrity of the vessel, never forgetting the aesthetics.

How is the quality control of coatings performed?

There is a very important preparation and painting process before a commercial vessel or a mega yacht is ready to set sail, and it includes a quality control step.
The quality control of the coating on commercial vessels and mega yachts involves the thickness measurement of paint applied. This thickness can be measured both dry (DFT) and wet (WFT).

Dry coating thickness measurement is performed during quality control and maintenance inspections. On the other hand, wet coating thickness measurement can be performed during the preparation and painting process since it does not require the coating to be completely dry as the name suggest.

The most common coating thickness measurement instruments are coating thickness gauges, used to measure dry layers applied on metal substrate, such as paint and plastic layers. A good example of these instruments are the high accuracy digital coating thickness gauges.

Coating thickness gauges work on both ferrous (magnetic) and non-ferrous (non-magnetic) metal parts, and depending on the material, the instruments will use either the Magnetic Induction or the Eddy Current measuring principle.

However, for wet coating thickness measurement a different type of gauges are used, which include the comb-shaped thickness gauges and the rolling wheel wet film thickness gauges.

Quality control at MCR Marine

MCR Marine Srl is a company formed by a group of professionals who specialize in the coating and painting industry, providing technical support before, after, during preparation and painting in the Commercial Vessels and Mega Yachts sector.

The service they offer does not only covers the painting of the vessel, but also the preparation and coating of accessories. In addition to the sectors mentioned above, MCR Marine is able to cover the needs of the whole marine sector.

MCR Marine Srl provides two main ways to guarantee the quality of their services:
• Inspectors certified by the major World bodies: Frosio, Nace, RMCI.
• Quality control tools and instruments properly calibrated according to the highest standards.

How calibrating quality control instruments helps MCR Marine Srl?

As we mentioned above, MCR Marine Srl performs preparation and painting of commercial vessels and mega yachts among other services, and quality control is essential in their activities.

By using the adequate tools for verification and evaluation of different activities such as materials hardness and coating or painting thickness, they can guarantee high-quality results to their customers.

However, as it happens with any other tool or instruments, measuring instruments require calibration periodically to ensure the values obtained are really accurate.

If quality control is performed with measurement instruments that are not calibrated, the operator may be making mistakes such as requesting extra coating which results in delayed delivery of the work or even worse, sending vessels to the customer with deficient coating which may result in premature failure.
So, how do the experts of MCR Marine make sure their tools and instruments are properly calibrated to match their high-quality standards?

One of the instruments we have calibrated for them is the shore analog hardness testers – SA6410 a non-destructive instrument used to measure hardness of parts made of rubber, plastic, stucco, sponges and similar materials. Other tools and instruments we calibrate for MCR Marine Srl are coating thickness measurement instruments.
MCR Marine relies on our calibration services because we help them comply with the UNI EN ISO 9001 standards.

Moreover, in case the adjustment of the instrument is required to fulfill calibration requirements, we offer such adjustment of the instrument as a specialized separate service to guarantee their needs are covered.

Through this specialized service, the experts at MCR Marine have always been able to guarantee more than satisfactory results to their customers. Working closely together has allowed us to develop a strong relationship that we are looking forward to maintain for a long time.
