“Canada-based manufacturer Gastops will collect data on the USCGC Polar Star — a ship built in the 1970s — to create a computer model that can undergo risk assessments at a relatively low cost, said Shaun Horning, president and CEO of the company.”
Results will feed into the planned service life extension intended to allow Polar Star to continue operating, at least until the second Polar Security Cutter is commissioned.
“…replacing the Polar Star’s 30-year-old analog control system with a digital control system will be one aspect of the refurbishment that will need to be tested extensively, Horning noted.”
This is the first time I have heard of the Coast Guard developing a “digital twin,” but this is becoming increasingly common. We can probably expect to hear of this being applied to other Coast Guard systems.
