The IACS Common Structural Rules (CSR) entered in to force 1st of April 2006. The new standard applies to all bulk carriers, single or double side, equal to or above 90 meters in length. See 'Downloads' for an introduction to the new rules and what DNV can offer.
Any Benefits of the new Rules?
- The new Rules will allow shipbuilders and designers to work with one common set of Rules, instead of one set from each class society
- The intention of the new Rules is to encourage the design and construction of robust tankers and bulk carriers and to eliminate competition on scantlings
- Stringent and clarified requirements to critical areas
- The minimum fatigue design life has been upgraded from the 20 year worldwide trading to 25 year North Atlantic environment
- The Rules include design standards for the net scantlings of a vessel meaning that the renewal thicknesses for the in service time is checked and known at the newbuilding stage
- The corrosion additions that have been established takes into account the location and the environment to which the structural member’s surface is subjected
CSR for Bulk carriers - software solutions by DNV
The new Rule requirements introduce a radical shift towards more computerisation of the rule formulations and structural assessment. As a response to this, Nauticus Hull - the leading class software - has been completely re-engineered to support the new Rules for Bulk carriers (more information about 'software solutions by DNV').
DNV's commitment to support the industry
While the DNV has been very active during the development of the CSR for Oil tankers, and has delivered software to support these Rules for a long time already, we have also scaled up our activity world-wide to assist clients in implementing the CSR for Bulk carriers. An extensive training program has been implemented for all approval units, enabling our staff to be well prepared to provide efficient and local support to the industry.
Hull Inspection Manual for Bulk carriers
Staying in control of maintenance is good business, and the Hull Inspection Manual (HullMan) from DNV is a practical approach to implementation of best-practise for ship maintenance. HullMan is developed in close cooperation with the ship manager. It utilises DNV’s extensive hull knowledgebase and incorporates the ship manager’s maintenance standard and work processes. HullMan is part of DNV's Hull Integrity Management program (more information about Hull Inspection Manual).
