Our technology has solved all major problems relating to ship hull performance and protection.
We have succeeded in providing a massive breakthrough in the field of underwater ship hull performance and protection. We have done this with a combination of our line of environmentally safe coating products and a profound knowledge of underwater maintenance work and tools. The result is a substantial reduction in fuel consumption, virtually zero emission and huge time and cost savings during newbuilding and drydocking.
1. Optimized surface friction
By optimizing surface roughness to its upper limits without future deterioration or degradation, we solved the problem of hull surface friction. As the coating has a lifetime equivalent to that of the ship, its surface characteristics are maintained over the same period.
2. Fuel savings
By optimizing hull surface friction and using the best possible surface hydrodynamic characteristics, proven fuel savings over the lifetime of the ship are most often found to be in the 20-40 % range. In contrast with AF compounds that rapidly degrade over time, our coatings last. Therefore the performance of the ship does not degrade either.
We have reduced the corrosion problem to a zero effect. Ship hulls handled by us keep their sacrificial anodes 100% intact, even after prolonged periods of 5-10 years in the water. Corrosion is virtually absent on our hulls and anodes are no longer needed.
4. Cavitation erosion
Cavitation erosion and corrosion thus caused is entirely solved. Cavitation erosion damage resulting in often very expensive repairs and time loss in drydock can now be avoided entirely. 450 rudders have been protected so far with a 100% success rate over a 15 year period.
5. Anti-fouling toxic particles emissions
Yearly 1 million tons of AF toxic chemicals and heavy metals are being used and lost at sea. This extremely damaging pollution results in billions of silt and sediment remedial cost. All of this can now become a thing of the past entirely, including the cost of removal.
6. Repeated application of degraded AF coatings
This is now an obsolete routine as our coatings last the lifetime of the ship. Peak distribution of toxic materials caused by repeated applications in drydock and thus emissions in ports and rivers has been overcome.
7. Time and effort in drydock
As reapplication is never necessary, work and time in drydock can be more than halved. Planning for work in drydock can be made to be very precise as paint renewal is avoided. Only small touch-ups may be needed. Waiting for acceptable weather is no longer necessary. This allows drydock companies to deliver on time. As a result, more ships can be docked in the same period.
8. Transfer of invasive species
This has become a totally manageable and cost-effective method and poses no major problems other than the repeated cleaning in-situ of the ship hull. This process is 100% environmentally safe. Even when done frequently, its cost is dwarfed by the fuel savings thus realized. Mitigation of the transfer of invasive species and very large fuel savings, never obtained before, are achieved by the same method i.e. regular in-situ underwater cleaning or other sanitation technologies.
9. Building costs
Cost for new building ships is substantially reduced as the repairs of these homogenous coatings, easy to apply and repair, are many times more efficient. This results in thousands of man hours saved during the building process. The reapplication of AF paint for speed trials in drydock at the end of the building period is not necessary any longer as a simple underwater hull cleaning is sufficient. The latter saves more than the total cost of the coating material supplied and the ship’s speed is guaranteed.
As the coatings will last the lifetime of the ship, they are now part of the investment. Other accounting and financial rules can be applied than if it were a simple repetitive application and therefore returning cost. The cost of repeated application of chemicals has changed into a fixed asset, entirely part of the ship.
11. Ice-going and icebreaking ships
RRS Ernest Shackleton, RRS James Clark Ross and HMS Protector, all of British Antarctic Survey, have been coated with our products with great and conclusive results. Our coatings have also been selected for the newbuild research vessel RRS Sir David Attenborough, the biggest commercial shipbuilding contract in Britain for 30 years. Another 150 applications on ice going hulls have shown that our coating can withstand the impact of ice for many years on end, proving its superior strength and durability.
We have optimized hull surface roughness and hence hull friction resulting in fuel savings in the 20-40% range. We have cracked all major problems in corrosion and cavitation erosion. We have halted all anti-fouling toxic emissions. We have substantially reduced the cost and time of drydocking and its peak distribution of toxic particles due to repainting work. We have provided the most adequate solution to mitigate the transfer of invasive species. We have reduced new building costs. We have formulated the best way to prevent loss of coating in ice and general arctic conditions.
