How does a bow type suggest either warship or merchant standard? Can't a specific bow be both?The curved clipper bow on the type 075 is totally unlike those on any other Chinese warship. It suggest to me this ship’s hull is based merchant design, and not warship standard. Whether that is actually so might be shown once we actually see the underwater hull form around the screws and propellers.
Absolutely. Bow design tends more to reflect the sea conditions, e.g. North Atlantic vs. South Pacific, and whether the ship is intended more for open seas or littoral waters.How does a bow type suggest either warship or merchant standard? Can't a specific bow be both?
So what is @Richard Santos talking about?Absolutely. Bow design tends more to reflect the sea conditions
Straight raked bows are popular because they are cheap to make, not because they are higher standard.
The curved clipper bow is more desired than a straight raked bow, but also more expensive to build. It is better than straight raked bow to keep waves to reach the deck in rough sea state. It also greatly increase buoyancy when the bow dips into the water. Many older built Navy ships choose this type.
Straight raked bow becomes popular in the Navies because it is easy and cheap to build. Just weld flat straight plates together, you get a ship. While to make that curve of a clipper bow out of steel plate, one need the huge press machine. There was a documentary recently talking about that press machine and how the Type 055 ships' clipper bow is made out of it. That machine can make any curve the designer want because it is computer controlled.
Prior of 055, the 052xs are using straight raked bows just like US Tico and Arleigh Burke.
The only advantage of Straight raked bow over clipper bow is that it has a little bigger volume at the bow which is preferred by commercial ships like most of the new yacht.
US Navy having several crashes have more to do with questionable seamanship and bad luck. The fact that the Burkes survived despite being cleaved by modern freighters or tankers is a testimony to the ship's bulkhead design. Of course, you never mess around with a modern freighter or tanker that is at least twice and more of your displacement, the higher the ship's total displacement is, the stronger the keel is, and can you imagine how strong the keel is for a ship that can displace up to 400,000 tons. As for Norway, I think no one remembered to close the doors inside the ship and that ship flooded relatively quickly.So what is @Richard Santos talking about?
Lets go on the same vane. Wouldn't the fact that the US navy had several crashes lately suggest that the ships were built to a much lower standard than we had initially thought? Seems plausible given whats happen.
The 075 looks like its been built with all the lessons from other professional navies. Not so much the US
(or Norway for that matter) who have adopted different philosophies.
