ABS Grants AIP to SDARI for Revolutionary Approach to Stern Tube Design
Redesigned Aft Layout Eliminates Oil Leakage and Enables Lower-Cost, In-Water Maintenance for the First Time (ATHENS) ABS has granted Approval in Principle (AIP) to the Shanghai Merchant Ship Design and Research Institute (SDARI) for a revolutionary vessel design with a novel aft layout, which eliminates pollution and promotes efficient vessel operations. The SDARI design, developed in cooperation with Thordon Bearings Inc. and the National Technical University of Athens (NTUA), introduces a new approach to the vessel’s aft layout, including removal of the stern tube casting,
