National Standard for Commercial Vessels

1
National Standard for Commercial Vessels

• Part C Section 3
• Construction

2
NSCV Construction Section will replace or update
the following sections of the USL Code

• Section 5A Preliminary
• Section 5B Structural Strength
• Section 5G Design Loadings
• Section 5H Aluminium
• Section 5I Copper Nickel Alloy
• Section 5J Ferro-cement
• Section 5K Fibre Reinforced Plastics
• Section 5L Steel
• Section 5M - Timber

3
Application of construction standard

• All domestic vessels other than special vessels
  stated in Part F
• Part F vessels include
• Fast Craft
• Hire and drive and
• Novel vessels

4
35 metres length more

• Deemed to satisfy solution is Class i.e. the
  vessel holds a current classification certificate
  with ABS, BV, DNV, GL, Lloyds or NKK
• Equivalent solution may consider vessels not in
  class but designed to class, plans approved to
  class and/or constructed to class (Part B of
  NSCV)

5
Less than 35 metres

• Deemed to satisfy solution may be rules contained
  in the Standard or rules referenced. Class is
  deemed to satisfy.
• Equivalent solution permits alternative standards
  subject to proof that standard meets required
  outcomes at least as well as the deemed to
  satisfy solution.

Focus of standard
7
Two levels of operation proposed

• Robust operations - loadings arising from-
• heavy seas (class A and class B and seagoing
  patrol vessels)
• heavy loads from cargo, machinery, deck machinery
  or rigging, frequent grounding (eg cargo vessels,
  ro-ro vessels, trawlers, crane barges, tankers
  etc)
• heavy or frequent impacts (tugs, ferries, barges)
• frequent grounding (land craft, large houseboats)
• large accelerations and slamming (dive, thrill
  ride, wake boarding and skiing vessels)

8
Two levels of operation proposed

• Light operations operations that are
  characterised by relatively light loading in
  normal circumstances, ie operations that are not
  robust operations.

9
C3 Construction

• Public comment draft standard and RIS are
  completed
• Public comment period to commence early December
  2006 (pending approval by NMSC)
• Reference group currently being formed

10
National Standard for Commercial Vessels

• Part C Section 6
• Stability

11
NSCV Part C Section 6 - Stability will replace
the following sections of the USL Code

• Section 8A Preliminary
• Section 8B Simplified Presentation of Stability
• Section 8C Stability Criteria
• Section 5C Watertight Sub-division of Passenger
  Vessels (Appendices 1, 2, 3)

12
NSCV Part C Section 6 - Stability

• 6A Intact Stability Requirements
• 6B Intact Stability Tests and Calculations
• 6C Damaged Stability
• Note 6A Intact Stability Requirements is
  currently out for public comment

13
Stability required outcomes

• Dangerous conditions of loading to be avoided
• Vessel to be capable of withstanding the effect
  of heeling moments
• Stability of a vessel to be established and
  verified
• Stability analysis to be appropriate
• Stability analysis to be sufficiently accurate
• Operator to be supplied with relevant information
  on stability
• Stability to be in a form suited to ready use by
  the operator

14
Fishing vessels

• Added-
• Snagged net condition
• Attempted retrieval of snagged net (stalled winch
  condition)
• Removed-
• Effect of water on deck
• Roll period tests
