Ecolock is designed to protect offshore vessels for decades without the need for drydocking. Increasingly, offshore units such as FPSOs, FSOs, FLRSUs and others used for offshore oil and gas exploration, drilling, storage and transport need to stay out of drydock for 15, 25 even 40 years. The challenge has been to protect the underwater hull from corrosion and to provide a cleanable surface so that the biofouling that accumulates can be removed successfully and safely for UWILD and to reduce weight. Ecolock is the answer to that challenge.
For decades it has been known that glassflake reinforced hard coatings last longer, are tougher and more resilient, need less repair and replacement than any other type of hull coating. Soft coatings such as biocidal antifouling and foul-release coatings do not hold up well. They need to be repaired or replaced often which is not good news for shipowners and operators and particularly offshore operators who need to keep their ships out of drydock. Their antifouling or foul release properties require that the ship move through the water at relatively high speed. On stationary vessels the fouling simply builds up.
Since the early 2000s a hard, cleanable, non-toxic, glassflake reinforced coating has been available, Ecospeed. Ecospeed is actually a coating system which combines a hard coating with routine in-water cleaning. The coating holds up for a remarkably long time, even in the ice or other harsh conditions. It can be cleaned as often as needed and becomes smoother not rougher with such cleaning. It has been used in offshore applications.
It was found over time that a tougher version of Ecospeed, Ecoshield, is an even more effective protection against the forces of cavitation and corrosion that constantly impinge on the rudder and other running gear of a ship. Now Ecospeed and Ecoshield have acquired a cousin, also a glassflake reinforced coating, but this one intended specifically to meet the hull protection requirements of offshore vessels: Ecolock.
Ecolock is an extremely tough and durable coating designed to remain in excellent condition for 15 - 25 years without drydocking, repair or replacement. Ecolock can be cleaned underwater as often as needed to meet the UWILD and weight requirements of FPSOs, drill ships and other offshore vessels. Ecolock is the result of continual R&D on offshore hull coatings since the 1990s.
