ClassNK has released the latest version of its design support software PrimeShip-HULL (HCSR) Ver.3.5.0., developed in response to the IACS Common Structural Rules for Bulk Carriers and Oil Tankers.

In response to the latest amendments to the IACS Common Structural Rules for Bulk Carriers and Oil Tankers (CSR BC & OT), ClassNK has just released its latest version, PrimeShip-HULL(HCSR) Ver. 3.0.0

PrimeShip software latest version is now able to calculate the added resistance in irregular waves ClassNK has released the latest version of its PrimeShip-GREEN/MinPower software. The software was originally developed by ClassNK and released in April 2014 to help shipyards comply with amendments to MARPOL Annex VI, specifically EEDI requirements, by calculating minimum propulsion power requirements in compliance with the IMO 2013 INTERIM GUIDELINES FOR DETERMINING MINIMUM PROPULSION POWER TO MAINTAIN THE MANOEUVRABILITY OF SHIPS IN ADVERSE CONDITIONS. With this updated software, users will now be able to calculate the added resistance in irregular waves, allowing for minimum propulsion power requirements to be determined to an even greater accuracy.To evaluate the minimum propulsion power requirement, added resistance in irregular waves must be calculated with ship's lines. ClassNK incorporated a new calculation module into the software to calculate the added resistance in irregular waves accurately developed by National Maritime Research Institute of Japan in addition to simplified formula for calculating added resistance in waves using only basic information.The PrimeShip-GREEN/MinPower software is provided to shipyards free of charge.Further information may be found on ClassNK websiteSource and Image Credit: ClassNK

Minimum Propulsion Power Calculation Software / ISO-based Progressive Speed Trial Analysis ClassNK has released the new PrimeShip-GREEN/MinPower software. PrimeShip-GREEN/MinPower was developed to help shipyards comply with the EEDI requirements of the Amendment to MARPOL Annex VI by calculating minimum propulsion power requirements in compliance with the IMO 2013 INTERIM GUIDELINES FOR DETERMINING MINIMUM PROPULSION POWER TO MAINTAIN THE MANOEUVRABILITY OF SHIPS IN ADVERSE CONDITIONS.To evaluate minimum propulsion power requirement, added resistance in irregular waves should be calculated based on ship's Lines. Calculating added resistance in waves can be difficult especially at initial design stage. That is why ClassNK developed a simplified formula to calculate added resistance in waves using only basic information such as main ship specifications, allowing designers to easily evaluate the minimum propulsion power requirement for their ships.In addition, ClassNK has released an updated version of the PrimeShip-GREEN/PSTA software, which was initially released in June 2013 to provide shipyards with an easy means of calculating progressive speed trial analysis in compliance with the ISO 15016:2002 standard recognized in IMO guideline 2012 GUIDELINES ON SURVEY AND CERTIFICATION OF THE ENERGY EFFICIENCY DESIGN INDEX (EEDI).Recently, a new draft of ISO 15016 was released. In order to support the industry's smooth ...
