Abstract
An improved Exhaust Intake Bonnet (EIB) for an Advanced Maritime Emissions Control System (AMECS) includes a shroud carried by a rigid upper frame and a lowerable and raisable rigid lower frame. The upper frame includes a peak with a duct for receiving exhaust gasses captured by the shroud and winches for lowering and raising the lower frame. The shroud is expandable when the lower frame is lowered and collapsible when the lower frame is raised and has a cinchable base. The AMECS is joined to a ship by positioning the EIB over a ship's exhaust stack using a deployment arm. The shroud is then lowered over the stack and then cinched around the stack to provide a soft attachment between the EIB and the ship's stack. Later, the steps are reversed to separate the AMECS from the ship.
