Comments: - -  ust a FYI for the one you did on ICE BREAKERS My information is from January 2022 ( workboats) sense you did not get into US builds.

I know the Polor class are aged. Halter Marine was Awarded a $555.2 million dollars for details Design and construction of NEW ( PSC) Polor Security Cutter. The vessel will be 460 feet. 88 foot beam.

Full load displacement of 22.900 long tons. It will be powered by Diesel Electric propulsion developing 45.200 Horsepower. Continue ice breaking ice between 6 to 8 feet. It will accommodate 186 personnel for extended endurance of 90 days.

Artic Princess should not be in the top 10, M-Class (Megara, Macoma, Myrina, Magdala en Murex) from Shell management owned by Teekay, has a capacity of 173.000 m3. Which is just 1000m3 less than Pan Africa, Marvel, and Gaslog Gribraltar. And Same as Patris, Flex. As well Q-Flex should have been mentioned.

Too bad all these western nation ones will be empty and not running soon, those oil prices won't stop climbing for a while and you cut off over half of the worlds oil and shipping lanes,

how much does america rely on imports from China and India alone? All going away...
