Greetings From New Orleans .
First of all , Thank YOU all so very much for your participation , your guesses and your thoughts on just what these objects may be . In all honesty , I too was puzzeled about the purpose and use of these rather unusual devices until I spoke to the Bisso Fleet and inquired to their use and purpose . Simply put , these are just water bags , filled with water , to a certain weight , and then used to test and determine the SWL , ( Safe Working Load ) which is mandatory for all Cranes and Derricks before they can be put into operation . The next time you have an opportunity to see up close a Crane or Derrick , there will be an imprint such as " SWL 100 tons " , for example , which will specify the limits of weight , what the respective Crane or Derrick may lift . Once again , Thanks for your participation and I hope this little exercise just may have broadened your horizons !!
Smooth Sailing !
