IACS has adopted new Unified Requirement (UR S35) which is a harmonised methodology that provides for independent buckling toolbox regardless of ship type. 

By working together, LR and ABS have provided fully up-to-date straightforward tools for the whole industry to use when applying CSR.

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

Common Structural Rules Software LLC, a joint venture company formed by ABS and Lloyds Register (LR), has released new software tools for meeting the requirements of the IACS Common Structural Rules (CSR), which entered into force on 1 July 2015.

LR awarded the contract for classification of the first ever vessels ordered by a Danish ship owner to the new Harmonised CSR (CSR-H)

The KR has radically overhauled its ground-breaking software package, SeaTrust-HullScan

Harmonized CSR for Bulk Carriers and Oil Tankers enforcement effective July 1st, 2015 Russian Maritime Register of Shipping (RS) has advised of harmonized CSR for Bulk Carriers and Oil Tankers enforcement on 1 July 2015, which will supersede the current Common Structural Rules for Double Hull Oil Tankers and Common Structural Rules for Bulk Carriers (Part XVIII and Part XIX of RS Rules for the Classification and Construction of Sea-Going Ships).The harmonized Rules will be inalterably included in the normative documents of all IACS members.The requirements of the new Rules will cover bulk carriers of unrestricted service, single or double hull, 90 m in length and upwards and double-hull oil tankers of unrestricted service, 150 m in length and upwards. The text of the Rules can be found by clicking hereTraditionally, IACS documents are so developed that the Technical Background Rule Reference is an indispensible part of the Rules. The Reference contains comments practically on every paragraph of the developed requirements, explains the essence of the requirement, quotes its source (IACS Unified Requirement, statutory requirement, requirement of a particular Classification Society, etc.).For the most essential requirements, Technical Background Reports are issued as separate documents forming an indispensible part of the ...

ClassNK has announced the release of Ver. 2.0.0 of its PrimeShip-HULL(HCSR) ship design support software

Reducing the time and cost of designing vessels in accordance with the new IACS ClassNK and NAPA have announced a new joint project to reduce the time and cost of designing vessels in accordance with the new IACS harmonised Common Structural Rules. The new project will enhance the data linkage between ClassNK's PrimeShip-HULL(HCSR) design support software with NAPA's 3D model based integrated design software NAPA Steel greatly improving the efficiency of the ship design process and reducing the cost of designing vessels in accordance with the new rules.Adopted in 2013, the IACS harmonised CSR will be applied to all tankers over 150m and all bulk carriers over 90m contracted after 1 July 2015. The harmonised CSR brings new requirements for more comprehensive structural analysis at the design stage, including FEM analyses covering the entire range of cargo hold structures, as well as new formulae for buckling, fatigue, and residual strength criteria to enhance safety and reliability. However, these new requirements also greatly increase the overall time needed for vessel design.In order to help reduce the burden of the new rules on ship designers, ClassNK released PrimeShip-HULL (HCSR), a multi-functional vessel design support tool that makes it easy for yards and ...
