  25. 2 MAJOR WORK Classification SHIP’S SAFETY DURING LIFE TIME Yard Design Maker Design • DRAWING APPROVAL • INSPECTION DURING BUILDING • CERTIFICATION • INSPECTION AFTER DELIVERY Intermediate Periodical GENERAL PROCEDURE OF SHIPBUILDING - DD/MM/YY

  26. CLASS PROCESS SHIP NEW CONSTRUCTION : Design review Commercial Follow-up in service T0 Contract RFC Signed T0 + C Deliveryto Owner Ad 523 signed byLPO GENERAL PROCEDURE OF SHIPBUILDING - DD/MM/YY

  27. DTM support BVN surveyors Field surveyor LPO Marine Center CLASS PROCESS Design review : basically 4 BV actors GENERAL PROCEDURE OF SHIPBUILDING - DD/MM/YY

  28. CLASS PROCESS Design review T0 Contract RFC Signed T0 + C Deliveryto Owner Ad 523 signed byLPO • LPO core activity : Design review • Design review can start before RFC signed ( TAKE CARE - CONTRACT DEFINITION ) • Completed when Ad 523 + annexes are examined and signed ( technical green light given to CM for Class certificate ) GENERAL PROCEDURE OF SHIPBUILDING - DD/MM/YY

  29. CLASSPROCESS Design review • LPO core business : Design review against Referential • Referential : BV Rules / IMO Reg. • LPO Interpretations : - allowed with BV Rules ( within general conditions) - not allowed for IMO Reg. • Rules : technical interpretations / protect interest of Owner ( final CLIENT ) • High technical knowledge frequently requested as Clients may be less educated / powerfull than BV • Great risk of uncontrolled move from design review activity to Consultancy activity T0 Contract RFC Signed T0 + C Deliveryto Owner Ad 523 signed byLPO GENERAL PROCEDURE OF SHIPBUILDING - DD/MM/YY

  30. CLASS PROCESS Follow-up in service T0 + C Deliveryto Owner Ad 523 signed byLPO Scrap or Changeof Class • LPO activity : • Design review at any time in case of conversion • Rules : technical interpretations / protect interest of Owner • Technical support of CMs / Station surveys • Several LPOs may be concerned • Technical documentation processing ( drawings + calculation sheets ) GENERAL PROCEDURE OF SHIPBUILDING - DD/MM/YY

  31. Different from Class design review : BV acts as designer in scope of Consultancy Technical expertise and knowledge is ( must be ) sold to Client Highly profitable HIGH RISK OF : - transfer of Yard know-how - confusion on status of conclusions - pressure from management ALWAYS BE CLEAR ABOUT THE CAP YOU WEAR / THE FORMAT OF COMMENTS YOU ARE ALLOWED TO GIVE TECHNICAL ASSISTANCE GENERAL PROCEDURE OF SHIPBUILDING - DD/MM/YY

  35. SUMMARY 1General : Large Container Vessels 2 Bureau Veritas References in Large Container Vessels BV Hull Expertise - Steps of review process - Torsion analysis - Fatigue analysis - Bow flare analysis 4 BV Lashing Expertise BV Shaft Alignment Expertise Parametric Roll Calculation

  36. 1 LARGE CONTAINER VESSELS GENERAL • The size range for the largest containerships is expected to increase significantly in the near future as economies of scale remains the dominant operational factor driving efficient transport. • The Largest containerships currently in service are in the 7000-8000 TEU range. Many leading shipyard have developed designs for vessels with additional containers rows, tiers and holds. Increase main dimension and capacity up to 9000/10000 TEU. • In the future the carrying capacity of containerships is expected to increase to 12000 TEU and above GENERAL PROCEDURE OF SHIPBUILDING - DD/MM/YY

PP 333,44 m Breadth 42,8 m Depth, to upper deck 27,3 m Draught, summer 14,5 m Speed 24,25 kn Power 68656 kW Key elements: Between half December and the end of March the complete structure has been reviewed. This was only possible in close cooperation with the Shipyard. Several meetings at the shipyard site, exchanging information and calculation results and discussing the findings, have taken place. Two offices of Bureau Veritas, Korea and Paris, have been working around the clock in order to make the deadlines of the shipyard. 2 PROJECT MANAGEMENT BV REFERENCES GENERAL PROCEDURE OF SHIPBUILDING - DD/MM/YY
