CHICAGO–(Business Wire)–Clerity Solutions, Inc., a leading provider of mainframe migration,modernization and optimization solutions, announced that CCVRP, a socialsecurity and unemployment benefit manager for sales agents in France, hasselected Clerity`s UniKix rehosting software and mainframe modernizationservices. provides engineering andconsultancy services for the design of various types of ships including generalcargo ships, container ships, oil and chemical tankers, passenger ships andferries, yachts, and navy ships.

Delta Marine also uses ANSYS technology to evaluate the structure and cargotanks of ships against worst-case load scenarios involving forces exerted by thetank`s contents against the tank itself. For example, the design andconstruction of sulfur- and bitumen-carrying tankers is complicated bycomplexity of the cargo tanks, which could either be built independently or aspart of an integrated structure.

By identifying vibration problems inthe early stages of the design process, Delta Marine can make alterations suchas adding pillars or strengthening structural components, or changing thepropeller, revolutions per minute of the crankshaft, or number of blades in thepropeller. Then, engineers can update the model to determine the effect of thechanges on vibration displacement and velocity. “The marine industry is challenged to develop and produce new designs at anaccelerating pace. Designing ships is not a straight-forward process: Thechanges are frequent and prototyping can be quite expensive. Delta Marine hasshown how Simulation Driven Product Development can be extremely effective indesigning vessels that mitigate risk – helping engineers make critical decisionsthroughout the design process,” said Dipankar Choudhury, vice president,corporate product strategy and planning, ANSYS, Inc.

If vibration values do not meet international standards,sometimes expensive changes must be made. “Engineers also have much more freedomwhen making design changes in the early stages.” Delta Marine engineers use software from ANSYS to calculate pressures induced bythe propeller on the aft of the ship as well as the loads generated on thepropeller shaft. This fluid structure interaction (FSI) can fatigue the hull`scomponents and cause vital equipment to malfunction. “Simulation analysis gives our engineers insight into the complexities of theseinteractions,” said Dirim Sener, planning director, Delta Marine Engineering Co.”Using ANSYS® technology, our engineers try to correct problems by modifying theship during the design stage – instead of discovering vibration problems afterthe ship is launched.” He added that changes made after launch could costmillions of dollars, while changing the underwater form of a ship in the designstage can be done at almost zero cost.
