Mavi Deniz Vessel Built-in Zero Velocity Oil Mop Skimmer is a high-efficiency skimmer for recovering from floating oil on water. A rope mop consists of oleophilic fibers woven into a rope that floats on the water’s surface. A set of ropes is suspended between catamaran hulls.

Mop Oil Skimmer unit selectively attracts oil and water-in-oil emulsions, ensuring the complete recovery of spilled oil entering between the hulls. The oleophilic rope mops are propelled between the side hulls at the vessel’s speed over the water, passed into the water at the bow of the vessel, and recovered over a roller fitted at midships.

They then travel along a tunnel to a hydraulically powered wringer unit, which removes the adsorbed oil and drives the mops. The oily mops are brought aboard, where water continues to drop off along the way. The oil is then completely removed from the rope when pressed as it goes through a wringer near the skimmer’s bow. The recovered oil is initially collected in a sump beneath the wringer unit then transferred via an onboard pump to the built-in storage tanks or alternative storage such as a floating tank.

Mop Oil Skimmer can recover oil over a wide viscosity range but are most effective with medium to thick viscosity oils. Unaffected by debris or ice, the rope mop is virtually indestructible and ensures pick-up in calm water or wave action since it is free to follow the waves’ contours. Oil recovery mops can be lifted from the water and held tight under the deck when not in operation to avoid contamination during dispersant spraying activities and to maximize vessel performance when maneuvering.

Mavi Mop Skimmer; Oil can recover without prior containment by directly driving the boats through the slick while operating the system. Typical water recovery with the system is less than 5%.
