The software was developed in response to the IACS Common Structural Rules for Bulk Carriers and Oil Tankers (CSR BC & OT).
In addition to improved overall performance and usability, the design evaluation function for the prescriptive calculation software now has a wider scope and additional functions, such as an evaluation function for bottom slamming have been added to the direct calculation software.
ClassNK said that it consistently strengthens the functions of PrimeShip-HULL (HCSR), a tool it provides to the industry completely free of charge, in order to make it easy for designers to carry out rule calculations in line with the CSR BC & OT and optimise their designs.
This latest version includes a number of major improvements.
The prescriptive calculation software is claimed to have reduced the time needed for calculations and improved user interface performance. Moreover, its initial design function, which is a function for quick sectional evaluation, is now capable of being used for structural arrangements in the fore and aft part of the ship, including the engine room, in addition to the cargo hold areas.
An evaluation function for bottom slamming has been added to the direct strength assessment software. This new function uses FE model for hold analysis required by the rules and includes automatic creation functions for evaluation panels, slamming loads and reports. In addition, it features an upgraded manhole modelling function, batch edit for multiple opening information and registering function for screening evaluation points.
