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 4 Loads - Section 8 Loading Conditions - 1 Application

1 Application

1.1 Ships having a length L of 150m or above

1.1.1 The requirements in [2] to [5] are applicable to ships having a length L of 150 m or above.

1.1.2 Design loading conditions for strength assessment

Design loading conditions for strength assessment are given in [2] to [4]. The design loading conditions common to both oil tankers and bulk carriers are given in [2]. Specific design loading conditions for oil tankers and bulk carriers are given in [3] and [4] respectively.

Unless otherwise specified, each of the design seagoing conditions is to be investigated for the arrival and departure conditions.

1.1.3 These requirements are not intended to prevent conditions to be included in the loading manual for which calculations are to be submitted. It is not intended to replace in any way the required loading manual/instrument.

1.1.4 Loading conditions from the loading manual, which are not covered in [2] to [4], if any, are to be considered.

1.1.5 Standard design load conditions for fatigue assessment

The standard design loading conditions for fatigue assessment are given in [5].

1.2 Bulk carriers having a length L less than 150 m

1.2.1 The severest loading condition from the loading manual, midship section drawing or otherwise specified by the Designer are to be considered for the longitudinal strength given in Ch 5 and for local strength check of plating, ordinary stiffeners and primary supporting members given in Ch 6 and Pt 2, Ch 1, Sec 3 and Pt 2, Ch 1, Sec 4.

The requirements in [2] are applicable to ships having a length L less than 150 m.

1.3 Dynamic load cases

1.3.1 Seagoing conditions

Unless otherwise specified, each of the design seagoing conditions are to be investigated for all dynamic load cases.

1.3.2 Beam and oblique sea dynamic load cases

For FE load analysis, the beam sea and oblique sea dynamic load cases calculated for port and starboard sides are to be applied on the model to obtain the results for both model sides.

For ship with structure symmetrical about the centreline, the beam sea and oblique sea dynamic load cases calculated for portside may be applied only to the model (i.e. dynamic load cases on starboard side may be omitted) provided the results (yield and buckling) are mirrored.
