Future Evolution

• Date of application 
• DE 47 did not decide and report on MSC
• MSC 78 (May 2004) has to decide the application
  date of amended texts (Solas Reg II-1/3.6

• IACS - Industry  Needs of up-date
  interpretations ?

Part 3 URS 31 VERIFICATION OF SIDE WEBS FOR THE
EXISTING BULK CARRIERS

URS 31 STRENGTH OF SIDE WEBS

WHAT IS BULK SOFTWARE

• BULK has been conceived to help owners and
  designers to assess the compliance of their
  single side skin bulk carriers of 150 m in length
  or above, with the IACS ships structural
  requirements.
• Based on a very user-friendly platform under
  Windows environment, BULK will provide the User
  with a comprehensive view of compliance with the
  new strength criteria.
• The Unified Requirements have already been
  included in BV Rules.

40
HOW THE BULK SYSTEM WORKS

• A Pre-calculation is carried out by BV Technical
  Dept. or by the Local Plan Approval Office
• Local Plan Approval Offices are located in
• CENTRAL PLAN OFFICE PARIS
• CHINESE PLAN OFFICE SHANGHAI
• DUTCH PLAN OFFICE ROTTERDAM
• FRENCH PLAN OFFICE NANTES
• GERMAN PLAN OFFICE HAMBURG
• HELLENIC PLAN OFFICE PIRAEUS
• JAPANESE PLAN OFFICE KOBE
• KOREAN PLAN OFFICE PUSAN
• MADRID PLAN OFFICE MADRID
• NORDIC PLAN OFFICE COPENHAGEN
• RIO PLAN OFFICE RIO DE JANEIRO
• SINGAPORE PLAN OFFICE SINGAPORE
• TURKISH PLAN OFFICE ISTANBUL

41
HOW THE BULK SYSTEM WORKS

• This pre-calculation is carried out with the
  software Bulk which has been specifically
  designed for the purpose of
• calculating the minimum required thicknesses
  before the survey is started
• allowing the Surveyor to take appropriate actions
  during the survey, with respect to steel renewal
  or repairs or reinforcements of the frames and
  brackets, by comparing the measured thicknesses
  on-board to the pre-calculated thicknesses.
• The calculation sheets are then sent to the
  SHIPOWNER and to the SURVEY CENTRE, when known,
  in advance of the survey.
• One calculation sheet is available for each frame
  which has been pre-calculated.
• The calculation sheet also indicates the
  concerned hold No. for each pre-calculated frame.
