Profilium: The Best Abrasive Blasting Solution in shipyards industry
Over the last few years, Profilium has been implemented with shipbuilding industry's top players and has proven to be the best abrasive blasting solutions for major companies such as South Korea's "big three" shipbuilders Hyundai Heavy Industries, Samsung Heavy Industries and Daewoo Shipbuilding & Marine Engineering.
Specific needs of shipbuilding industry
This booming market faces many challenges such as volatile raw material prices and high labour costs and is subject to rigorous specifications of International Maritime Organization (IMO) which looks to increase vessel safety and lifecycle by preventing corrosion.
The new regulations (PSPC) concerning surface treatment and coating application adopted in July, 2008 need to be taken into consideration by all departments involved in vessel production, especially by blasting and coating units. Surface preparation which involves the removal of rust, salt, mill scale, weld spatter and in some cases old paint, and rounding of sharp edges is critical to achieve optimum performances of coatings. This labour intensive process represents a significant part of total costs of the coating process.
As the leading manufacturer for metallic abrasives, WINOA is well aware of the challenges faced by the marine industry and determined to offer better performance and serious cost savings.
Premium Solution for Surface Preparation in Shipbuilding Industry
Profilium was developed and tested by top players of marine industry: it documented to perform well above of the expected levels in terms of blast efficiency, surface roughness and paint consumption.
1. Blasting Quality and Efficiency
One of the key Profilium users, a leader in ship construction, had difficulties with the removal of rust from sharp corners. After blasting, a great amount of rust remained between welding lines which required extra work and resulted in time loss due to rejections of work process.
The optimized size distribution, shape and hardness of Profilium enabled the removal of the rust between welding lines.

The customer achieved +35% to + 45% efficiency (in blasted m²/hr)
for same cleanliness level of Sa2.5 by implementing Profilium.

2. Roughness
Another key player in the marine industry needed to improve the surface roughness achieved. After trials, this customer noted that the surface profiles reached with Profilium were finer and much more homogenous. The results of blasting confirmed that the roughness obtained is in conformity with PSPC specifications.

75-85 µm |
| Profilium |
45-55 µm |
3. Paint Consumption
After test trials, this customer measured a considerable difference in terms of paint consumption between Profilium and the grit they were using. The finer roughness obtained by Profilium reduced significantly the amount of lost paint volume. The customer documented at the end of the year, a total saving of 3% in paint consumption which exceeded their expected levels.

The top players of shipbuilding industry documented an improvement of -8.7% in their total blasting costs along with a total saving of 10% in terms of labour cost and electricity. One of them could even save a major investment by cancelling a project of new air blast rooms to increase the production thanks to the high blast efficiency achieved by Profilium.
The success achieved with Profilium is the result of the Premium Approach:
|
A full service given to you at every step of the process:
1- Presentation and training seminar to introduce Profilium
2- Complete evaluation of your blasting process through calculation and simulation of air-blasting cost
3- Test launch and full technical assistance (on site tests, on-site training, air-blasting process monitoring…)
4- Evaluation of the results after the trial period
