Ecospeed stays intact for 20 years with underwater maintenance

Every hull coating fouls and as a result cleaning is an unavoidable reality for shipowners. For most coatings this is a problem because they cannot be cleaned without damaging them, often very severely. Ecospeed, however, was designed to be maintained regularly while keeping the coating intact for 20 years or longer.

The best and most viable approach is to clean the ship 100% and to do so regularly and always before sailing if the ship has been stationary and has fouled for a long period.

Ship hulls must be protected with a system that lends itself to fast, effective underwater cleaning without risk of damage to the coating and without posing any kind of hazard to the environment. Ecospeed is this system.

Fast and efficient fouling control

1. Underwater cleaning improves the hull surface
With repeated underwater hull cleaning Ecospeed’s surface further improves. This procedure is made easy by the coating’s technical properties. Cleaning can be carried out whenever needed, at any point in its lifespan, without causing damage.

2. Long lay-up periods have no effect
Ecospeed is suited for ships which have a stationary period. An impermeable and impenetrable barrier is created during application. This gives the coating excellent and durable anti-corrosive properties. It also protects the underwater hull against mechanical damage. No rust or damage to the steel will be present on the underwater hull of the vessel after cleaning and this despite the aggressive nature of certain types of fouling. The hard fouling is unable to penetrate or damage the coating.

3. Toxic free
Independent tests have been carried out to authenticate Ecospeed’s non-toxicity. This research proved that the coating is 100% non-toxic. There is no negative effect on the water quality or the marine environment at any point of its application or use

4. The definite biofouling solution
The underwater cleaning of Ecospeed prevents the spread of biofouling entirely. The cleaning interval is optimized to minimize fouling. Regular cleaning prevents macrofouling from building up. At the same time it presents an opportunity to inspect so-called niche areas. Most of the fouling organisms will be destroyed during cleaning. When only microfouling or locally acquired macrofouling is cleaned off the hull and niche areas, the risk of translocation of NIS via hull fouling is minimal.

5. Underwater cleaning allowed
The results of above-mentioned tests were sent to port authorities and environmental agencies worldwide. As a result, several major ports have overturned the existing general ban on underwater hull cleaning. They specifically made an exception for vessels coated with Ecospeed.

6. Specially designed equipment
Underwater maintenance of Ecospeed is carried out with specially designed underwater hull cleaning systems. These tools remove all fouling and at the same time optimize the smoothness of the paint surface. A complete line of equipment was designed in-house. They allow divers to clean the flat areas as well as the harder to reach parts of the hull without damaging the coating.

7. Fewer and shorter drydockings
There has been a trend of extending the maximum drydock interval if a stringent set of rules is followed. One of the requirements is the execution of a very strict underwater maintenance plan. The biggest barriers are dealing with biofouling and maintaining hull coating integrity. Ecospeed allows ship owners/operators to overcome both these barriers. Our coating can easily last for ten or twelve years without any need for drydocking.


Ecospeed can be cleaned underwater without risk of chemical pollution to the environment or of damage to the coating. Ecospeed’s surface will improve in smoothness with each cleaning. Underwater maintenance prevents the spread of biofouling. For these reasons several economically important ports have already overturned the existing general ban on underwater hull cleaning of Ecospeed.

The coating’s qualities make it ideally suited for a very strict preventative underwater maintenance plan. This is part of the requirements to extend a vessel’s drydock interval.

Underwater maintenance of Ecospeed is carried out with in-house designed underwater hull cleaning systems. These allows the cleaning of the hull without damaging the coating.
