I am not a helicopter pilot, but here's my research on the picture here.
The vessel was renamed to Megan in 2022 after Megan McArthur, the second female NASA astronaut to fly on a SpaceX Dragon capsule. The ship has 1750 horsepower from 2 caterpillar engines.
Comparing it with the published length of the vessel, it's plausible that the 17s on the helideck indicate that it has a 17 meter diameter. The smaller marking is "9.1t" which indicates a maximum takeoff weight of 9.1 (metric?) tons. At a casual glance many non-pilots would see "9.11" instead.
