Clasification Society Rulefinder 2020 - Version 9.33 - Fix
Common Structural Rules - Common Structural Rules for Bulk Carriers and Oil Tankers, January 2019 - Part 1 General Hull Requirements - Chapter 9 Fatigue - Section 6 Detail Design Standard - 1 General

1 General

1.1 Purpose

1.1.1

Design standard provides fatigue resistant detail design at an early stage in the structural design process by giving consideration to the following aspects:
  • Application of fatigue design principles.
  • Construction tolerances and other practical considerations.
  • In-service experience and fatigue performance.
1.1.2
The design standard is to be applied to the design of ship structural details in following steps:
  • Highlighting potential critical areas within the ship structure.
  • Identification of the fatigue hot spot locations for each of the critical structural details.
  • Provision of a set of alternative improved configurations from which a suitable solution can be selected.
  • Requirements on geometrical configurations, scantlings, welding requirements and construction tolerances.
  • Post fabrication method of improving fatigue life, such as weld toe grinding.
1.2 Application

1.2.1

The structural details described in this section are to be designed according to the given design standard but alternative detail design configurations may be accepted subject to demonstration of satisfactory fatigue performance.

For the details given in Ch 9, Sec 2, Table 3, the fatigue assessment by very fine mesh finite element analysis may be omitted if the detail is designed in accordance with the design standard given in this section.
