URS 31 – STRENGTH OF SIDE WEBS

WHAT IS “BULK” SOFTWARE: 

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 ship’s 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.

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 HOW THE “BULK” SYSTEM WORKS

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. HOW THE “BULK” SYSTEM WORKS
