Forbes suggests that the Chinese are planning to use some of their new ships to shoulder US ships.
Those flat sides aren’t an aesthetic choice, according to Jerry Hendrix, an American naval expert and author of the new book To Provide and Maintain a Navy. They’re for what sailors calls “shouldering.” That is, muscling into a rival ship and forcing it to change course.
Given that the Coast Guard is sending ships into the Western Pacific and participating in Freedom of Navigation Exercises, this threat is significant for us.
I have a lot of respect for Jerry Hendrix. I bought his book. But first, of course, most ships incorporate flat sides over a significant length simply because it is the cheapest construction method. Our National Security Cutters may have stealth incorporated in their design, but look at the OPCs.
OPC “Placemat”
The article specifically calls out two classes of Chinese ships as likely to be used for shouldering, the Type 055, which is a cruiser or large destroyer, and the “Chinese coast guard’s patrol ship Haixun.”
I certainly would not dispute the Chinese’s propensity for employing shouldering or even ramming. They have employed these techniques in enforcing their claims of sovereignty over the South China Sea, as identified by their still ill defined “nine dash line,” but I think they have called out the wrong ships.

Haixun is not part of China Coast Guard, it is a unit of the China Maritime Safety Administration which is their SAR agency. This agency has not been used for law enforcement.
The Type 055 is a very well equipped combatant and probably one of the most expensive units in the Chinese Navy. Her hull is not unusual and not a significant departure from that of the preceding Type 052D class. Their sides are not particularly flat. They are not units the Chinese would risk damaging.

Any of the China Coast Guard units could be used for shouldering or even ramming, but their heavy weights are two ships of the Zhaotou class, Haijing 2901 and Haijing 3901. These are the world’s largest Cutters and probably over 12,000 tons full load–about three times the size of the National Security Cutters. They are also capable of 25 knots.

The post suggests that the Mumford Point class T-ESDs and ESBs, based on a double hull tanker design would be an appropriate counter, but while they are large (60,000 tons and 785 ft (239 m) long), they are also slow (15 knots), not very powerful for their size (24 MW or about 32,000 HP), and not very maneuverable.
If we had more icebreakers, we might want to send one of them. We know what can happen when a lightly built ship plays bumper boats with an ice class vessel. On the other hand, the Chinese have started building icebreakers and ice strengthened merchant vessels, so we might want to keep that in mind.
Maybe the Navy has another reason to consider ice-strengthened ships.
