IACS Common Structural Rules Bulk Carriers MTPNO876 – Bulk Carriers and Container Ships 01 March 2006

Slide 2

IACS CSR Individual society Rules Safety level What is CSR? Rules covering auxiliary prerequisite for Bulk Carriers and Tankers, both newbuilding and in administration A Rule set connected in a precise way using cutting edge computational techniques for more broad direct figurings Vessels worked to CSR should have general wellbeing of the body structure equal to or superior to anything that at present accomplished in connection to life, environment and property Safety level surpassing any IACS individuals existing Rules. Adaptation

Slide 3

Why CSR? To dispose of rivalry between class social orders concerning auxiliary necessities and norms To utilize the consolidated involvement and recourses of all IACS social orders to build up a solitary standard, or set of Rules To guarantee that a vessel meeting this new standard will be perceived by the business as being in any event as protected and vigorous as would have been required by any of the current Rules To completely grasp the expectations of the foreseen IMO prerequisites for objective based new development guidelines. Variant

Slide 4

CSR - Benefits to the business Greater straightforwardness of the specialized foundation to the Rules Reduced cost for ship yards by identifying with one arrangement of basic Rules just All IACS social orders will coordinate to keep up a solitary Rule set Competition will be centered around administration level covering pre-contract, arrange endorsement, newbuilding supervision Ability to brisk and proficient critical thinking amid ship in operation (SIO) No opposition on scantling prerequisites and Rule standard Version

Slide 5

DNV - Ambitions To be the best programming provider for CSR. The CSR Bulk programming will mirror the accomplished picked up by the effective CSR Tank Software officially perceived by clients around the world. To be the favored dialog accomplice for proprietor\'s trying to contract CSR vessels. To be the favored accomplice for yards and planners creating CSR vessels. Presenting ship yards and creators worldwide to the new standards, where among broad programming preparing and run foundation clarification are advertised. To be seen as the most proactive and critical thinking class society through real intrigue and picked up information about proprietor\'s operational difficulties. Adaptation

CSR - harmonization Short term harmonization preceding selection by IACS Long term harmonization Implementation and industry remarks Detailed harmonization arrange Feedback period Harmonized CSR into compel Harmonization work inside IACS 2006 2008 2009 2010 2007 2011 Version

Slide 9

CSR Bulk - Application Applicable for Bulk Carriers with L ≥ 90 m marked for development after 1 April 2006 where: Bulk Carrier is a maritime self-pushed dispatch which are built by and large with single deck, twofold base, container side tanks and with single or twofold side skin development in payload length zone and planned principally to convey dry cargoes in mass. L < 350 m L/B > 5 m B/D < 2.5 m C B ≥ 0.6 Version

Slide 10

CSR Bulk Carrier when all is said in done CSR Not CSR Version

Slide 11

CSR Bulk – inquiries and answers If an agreement marked before first of April 2006 yet development won\'t begin until 2007? Boats or arrangement of boats marked for development before 1. of April 2006 is not subject to CSR regardless of the possibility that the development is occurring later than first of April 2006. Such ships will be liable to current DNV Rules. Imagine a scenario in which a ship building contract, marked before first of April 2006, incorporates choices for extra ships, to which standards ought to the discretionary boats be built. Choices incorporated into contracts marked before first of April 2006 is not subject to CSR if the alternative is practiced inside a year of the underlying contract marking. Imagine a scenario in which a ship building contract, marked before first of April 2006, is corrected, to which Rules ought to the extra ships be developed. Revisions is liable to the Rules in drive at the date of marking the correction. In the event that the revision is marked on or after first of April 2006, the boats are liable to CSR. Shouldn\'t something be said about SOLAS XII "Extra security measures for mass transporters" necessities which come into drive July 2006? For a vessel subject to CSR, SOLAS XII is naturally secured. For vessels not subject to CSR, but rather subject to DNV Bulk Carrier Rules and with bottom laying on or after first of July 2006, the SOLAS XII necessities are to be taken care of independently. Variant

Slide 12

CSR Bulk – inquiries and answers Will vessels consenting to DNV Nauticus(Newbuilding) meet the criteria of the CSR? No. For the Nauticus(Newbuilding) outline parameter is 20 years World Wide while 25 years North Atlantic is connected in the CSR. What\'s more, extraordinary yielding and locking criteria is connected in CSR. Will it be conceivable to adjust a current DNV Nauticus(Newbuilding) endorsed vessel to consent to the new CSR criteria? Such change would no doubt implement substitution or adjustment of key basic individuals. It is improbable that such alterations could be considered financially practical. What might be included to update and energizing CSR estimated configuration to meet the CSR criteria\'s? In view of present involvement, an expansion in steel weight of 2-4% and up to 7-9% is normal relying upon the first outline premise. E.g. an IACS URS25 consistent vessel will typically fall inside the primary classification. DNV is as of now collaboration with leader mass transporter fashioners to help with overhauling their outlines to meet CSR. Rendition

Slide 13

CSR Bulk – inquiries and answers Will an outline as of now checked on and endorsed as meeting the CSR by another IACS part be acknowledged by DNV? As the plan is as of now inspected and endorsed by an IACS part, no critical distinction in scantlings is normal. Nonetheless, to check such desire, DNV will do full arrangement endorsement. In the event that inconsistencies are uncovered this will be tended to in the suitable IACS discussion. Adaptation

In Service Design Wastage Allowance Corrosion Addition Predicted erosion in 2.5 years (0.5 mm) Required Net Thickness Required Renewal Thickness Annual Thickness Measurements CSR – Net scantling approach Version

Slide 19

CSR – Corrosion increments Corrosion expansion decided in view of the earth to which the basic part is subjected. E.g. t c1 , presented to ocean water = 1.0mm t c2 , water balance tank when all is said in done = 1.2 mm t hold , greatest thickness reduction in 2.5 years = 0.5 mm Total erosion expansion: t c = Roundup 0.5 (1.2 + 1.0) + 0.5 = 3.0 mm t c2 t c1 Version
