Environmental Systems

USCGC MACKINAW (WLBB-30) meets or exceeds all International, Federal, State, and Local environmental requirements, with possible future requirements considered.

The cutter’s environmentally-friendly systems include:

Double-bottom hull to move fuel tanks away from hull bottom
Box-type coolers are used for machinary cooling water. All cooling water stays internal to the ship, preventing any potential leakage from being improperly discharged. (Similar to nuclear plant designs)
Zero discharge of gray water and all trash is retained aboard
The diesel engines meet the latest MARPOL regulations for engine emissions
The propulsion pods incorporate multiple seals between the lubricated parts and the pod exteriors, including a void space to detect water ingress or oil egress

USCGC MACKINAW (WLBB-30) is also capable of providing maritime environmental response through the deployment of a Vessel of Opportunity Skimming System (VOSS). The VOSS system skims oil from the surface of the water to inflatable oil barges. The cutter has the capability to handle two inflatable barges with capacity of 28,000 gallons each.
