2 Yacht ? Limited number of passengers Private - commercial (e.g. charter) SOLAS exempted (normally)

3 DNV HSLC Rules - Notation Yacht LC:   (0,13 ·L·B) 1,5 HS:V  7,16   0,1667 &  25 knots Service restr.:R0, R1, R2, R3, R4 Yacht:Requirements given in Pt. 5 Ch. 5   1A1 HSLC Yacht R...  1A1 LC Yacht R... Objective: level of safety as for commercial passenger service

4 Objective: level of safety level as for commercial passenger service Safety Principles (ongoing) Technical rule requirements: Development - DNV Yacht Rules To cover all types of vessels: HSLC (motor and sail) and steel ships

5 DNV HSLC Rules - Notation Yacht Differences from HSLC basic Class: Not for commercial operation, but charter included Reduced minimum thicknesses may be accepted Requirements to sill heights may be reduced based on special consideration Reduced number of deadlights Reduced weight of anchoring equipment Reduced requirements to certification of machinery components Different requirements to fire prevention, detection and fighting

6 Lloyd’s List

7 DNV experience - Motor vessels Speed 15  70 knots Length 18  76 m Steel Aluminium Carbon/glass/aramid fibre reinforced plastics

8 DNV experience - Sailing vessels Monohulls Catamarans Length 20  75 m Carbon/glass/aramid fibre reinforced plastics

12 Yachts in operation – HSLC Yacht

13 Yachts in operation - Typecode Yacht

14 Sailyachts - Rule proposal Status: On external hearing. Planned completed Consider especially: - rig attachments (mast step, stays etc.) - rig loads on hull (hull bending etc.) - keel and keel attachment

15 Why chose DNV Ensures adequate safety level for persons on-board Reduces project risk - third party verification of delivery Expertise in lightweight construction - design and manufacture Expertise in FRP and steel/alum. construction Efficient approval process World wide presence Extensive consulting services Extensive statutory experience

16 Statutory certificates Requirements to statutory certificates depends on: type of operation (commercial/private) size flag  Will have effect on vessel design  Must be known at specification stage

17 Statutory certificates - “Normal” yachts Tonnage Load Line MCA (Marine and Coastguard Agency, UK)

18 Statutory certificates - “Large” yachts Tonnage Load Line MCA (Marine and Coastguard Agency, UK) Safety construction Safety equipment Safety radio Safe manning Oil pollution prevention ISM

19 Consulting services DAP - Design Approval Preview SDR - Structural Design Review MDA - Main Drawing Approval Finite element analysis Hull statement of compliance Hull survey

20 Consulting services Direct load analysis Slamming response Structural response Noise & vibration calculation

21 Future requirements MCA: “MCA Code of Practice for Safety of Large Commercial Sailing and Motor Yachts ” New revision planned finished 2003

22 DNV Composite (FPR) Rules Complete update to cover state of the art for composite materials - design methods - manufacturing methods - materials - testing
