And that is how the shipyards make their money. Our management was always beating up on us to minimize changes.
Dan,I believe you know my shipyard history and how I ended up there....for everyone else that would wonder why a pilebuck would go to laying out ships....
My back had been busted up pretty good and had been limping for a while, so with my layout and engineering background, went to Todd Shipyard Seattle to layout ships on the ways for new construction for three and a half years, and another year at Lockhead Shipyard Seattle
I came on board at Todd just before the launching of their seventh Oliver Hazard Perry
-class FFG. As originally designed they were 4000 long tons, and the modifications and change orders were at the Navy's request. The hulls on the first two ships flexed considerably during sea trials which resulted in changes to the double bottom, thickness of the keel and double bottom sideshell(plating) and closer spacing of the longitudinals in the web frame/longitudinal construction. There were changes to the rolling keel, skeg and upper side shells,bulbous bow, house, shaft alley and the foundations for the twin gas turbines and the single reduction gear. There were also changes to the house, CCC, and the missle storage and launch room, The final builds resulted in a calculated 4100 long tons.
All these changes were gradual and progressive through the first three ships and continued to a lesser extent through the next five ships. A few of these ships were for the Australian Navy, which resulted in further changes. There were also changes in systems and armament, as well as changes in machinery and equipment in the AMR's (holds>auxilary machinery rooms). My first job, more of a test then anything, was laying out the for the metal letters of the name STARK
on the compound curve of the stern. Strange to say I had a funny feeling about that hull, little did I know how that feeling would play out down the road. http://en.wikipedia...._Stark_(FFG-31)
Also laid out the Australian Navy's FFG's HMAS SYDNEY
and HMAS DARWIN
, and the USS HALYBURTON
....by the spring of1983 I could walk nomal without a limp, and was going to go back to Pilebucking, but Lockheed dangled a carrot and so I laid out on the ways,two of Whidbey Island Class Landing Ship Docks, the USS Whidbey Island
and the USS Germantown
Then I went back to Pilebucking and making the big bucks.
