Investigative Panel on Large Container Ship Safety findings (Image Credit: FleetMon.com)In response to the casualty of "MOL COMFORT" which occurred on 17 June 2013, ClassNK established the Investigative Panel on Large Container Ship Safety, comprised of leading experts from shipbuilders, shipowners and academic institutions.ClassNK issued the findings and outcomes of the panel consolidated into a report.Investigation of Structural SafetyAs stated in JG Report, it is inferred that in the fracture accident, the bottom shell plates were buckled and collapsed in the midship part of the Ship first and the hull girder was fractured subsequently in a short time. As far as investigated, there have been no cases in the past where collapse of bottom shell plates was the origin of hull girder fracture.It is essential to find out the mechanism of the hull girder fracture and to establish adequate assessment procedures for the hull structural strength in order to prevent similar fracture accidents.In this investigation, 3-hold model elasto-plastic analyses were carried out on a number of large container ships including the Ship and the margin against the expected loads was investigated. The relationship between the buckling collapse strength of bottom shell plates and the hull girder ultimate strength was also ...

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
