Ellipsoid exhaust intake bonnet (EIB) for maritime emissions control system

An Exhaust Intake Bonnet (EIB) for an Advanced Maritime Emissions Control System (AMECS), the EIB comprising:

• a top piece;
• a duct connector horizontally centered on the top piece connectable to a duct for carrying exhaust gasses from an Ocean Going Vessel (OGV) to an Advanced Maritime Emissions Control Unit (AMECU) for processing;
• outwardly and downwardly extending outwardly center arced ribs attached to the top piece and forming a cage, the ribs normally residing in an open position allowing the EIB to be lowered over a stack of the OGV and biasable to a closed position closer to the stack;
• first and second cinching lines reaching around bottoms of the ribs and connecting the bottoms of the ribs for cinching the bottoms of the ribs to pull the bottoms of the ribs closer to the stack;
• the first cinching line connecting with even ribs and not connecting with odd ribs between the even ribs and cinching only the even ribs;
• the second cinching line connecting with the odd ribs and not connecting with the even ribs between the odd ribs and cinching only the odd ribs;
• and
• a shroud lowerable and raiseable inside the cage, the raising and lowering of the shroud independent of cinching the bottoms of the ribs.

• first, second, and third cinching lines reaching around bottoms of the ribs and connecting the bottoms of the ribs for cinching the bottoms of the ribs to pull the bottoms of the ribs closer to the stack;
• the first cinching line connecting with a first, fourth, seventh, and remaining third ribs and not connecting with ribs between the first, fourth, seventh, and remaining third ribs and cinching only the first, fourth, seventh, and remaining third ribs;
• the second cinching line connecting with a second, fifth, eighth, and remaining third ribs and not connecting with ribs between the first, second, fifth, eighth, and remaining third ribs and cinching only the second, fifth, eighth, and remaining third ribs;
• the third cinching line connecting with a third, sixth, ninth, and remaining third ribs and not connecting with ribs between the third, sixth, ninth, and remaining third ribs and cinching only the third, sixth, ninth, and remaining third ribs;
• and
• a shroud lowerable and raiseable inside the cage, the raising and lowering of the shroud independent of cinching the bottoms of the ribs.
