The landmark ABS condition-based class program with the U.S. Navy’s Military Sealift Command (MSC) was the focus of a keynote presentation at Mega Rust 2019, ABS said in its release.
Rear Admiral Dee Mewbourne detailed progress on the pioneering project in a presentation to the American Society of Naval Engineers’ annual conference focusing on Navy corrosion issues.
As part of the condition-based class program, ABS has defined a digital asset framework that encompasses everything from data collection and pre-processing, to a digital twin that maintains and analyzes the data, to visualizations and outputs that support risk-based decision making.
The objective of the multi-year joint project is a landmark advancement in the classification industry—enabling the move from purely calendar-based surveys to a condition-based classification model, using digital solutions to increase MSC’s operational availability and flexibility.
ABS is working in an unprecedented degree of integration with both MSC and vendors to share data and enrich the digital picture of three vessels:
USNS SPEARHEAD, an expeditionary fast transport craft
USNS AMELIA EARHART, a dry cargo/ammunition vessel
USNS POMEROY, a large RO/RO vessel
At the center of the project, ABS has performed an in-depth baseline survey assessment for both structures and machinery and built Digital Twins for each vessel which utilize data from newly installed hull sensors and sensors on classed machinery. Combined with ABS’ advanced analytics, the Digital Twins provide an up-to-date source of information that provides decision-makers with the data they need when they need it. With this vessel-wide intelligence, ABS and MSC have a more holistic view of the vessel’s current condition and can better forecast future conditions to drive classification activities and support operational decision making.
