Professor Fred Stern of the University of Iowa College of Engineering describes the new $4.9 million wave basin facility at the University of Iowa's research campus. This wave basin will be used by Stern and his colleagues in UI's Ship Hydrodynamics Research Group to further develop the simulation software called CFDSHIP-IOWA that they have developed for the United States Office of Naval Research to aid in the ship design process. The UI Ship Hydrodynamics Research Group is a program of IIHR- Hydroscience & Engineering, one of the nation's preeminent institutes for the study of fluid mechanics, air and water resources, and environmental hydraulics. to learn more: http://iihr.uiowa.edu

"Cruise ships are also known as passenger ships. There are certain similarities between cargo and cruise boat building methods with differences in construction happening at a later stage. The basic design and construction of the hull of the ships remain the same with difference in construction during the finishing of the vessel. As cargo vessels are fitted with container clamping and loading equipment, oil tankers are subdivided, sealed, and fitted with inert gas systems, and cruise ships are fitted with luxurious items to provide comfort to the travelers that shall be sailing on the vessel. Today cruise ship sailing is done for tourism purposes; this means that people are paying a lot of money to sail on these ships, so they require all modern facilities that are found in hotels. "
"Unlike in the past when vessels were constructed as one piece, today ship builders have changed their approach and ship building has changed. The hull and deck of the vessel are constructed in pieces that are prefabricated at different locations. When ready, they are lifted in to place and welded. This form of construction is called block construction; pipes and electrical cables are preinstalled in the block to minimize time used on installation. "
