ISO 12215-5 / Small craft — Hull construction and scantlings — Part 5: Design pressures for monohulls, design stresses, scantlings determination
Year: 2024 Language: English Author: ISO Genre: Нормативный документ Publisher: ISO Edition: 2nd edition / Corrected version Format: PDF Quality: eBook Number of pages: 136 Description: The committee responsible for this document is ISO/TC 188, Small craft. This second edition cancels and replaces the first edition (ISO 12215-5:2008, including its amendment ISO 12215-5:2008/Amd 1:2014), which has been technically revised. One of the main reasons to achieve this revision, after a decade implementing the first edition, was to allow other scantlings calculation methods than those given in the 2008 edition, noting the huge development of finite element analysis methods and software, and the trend already applied in ISO 12215-9 (keels and appendages) and ISO 12215-7 (multihulls). Therefore, in this new edition, like in many other scantlings standards, the design pressure loads, and the design stresses are given in the main body of the standard and, where needed, the scantlings calculation methods are detailed in Annexes. The main changes compared to the previous edition are as follows: — clarification of the scope and of many definitions, dimensions, and assessment; — definition of a theoretical hull/deck limit height ZSDT in Table 3; — renaming of nGC into kDYN in Table 7; — lowering of the values of kL in the aft part of the craft in Table 8; — deletion of kAR min, to better consider large panels, mainly sandwiches, in Table 9; — improvement of the values of kSUP in Table 10; — modification of design pressures for motor and sailing craft in Tables 12 & 13; — modification of design stresses introducing kBB and kAM factors in Tables 15 to 17; — incorporation of requirements for work boats in Table 2, Clause 12 and Annex J; — possibility to use a wider range of assessment methods detailed in Table 18; — move of the previous assessment method (now called "simplified") in Annex A; Additional info: This document defines the dimensions, design local pressures, mechanical properties and design stresses for the scantlings determination of monohull small craft with a hull length (LH) or a load line length (see NOTE 1) of up to 24 m. It considers all parts of the craft that are assumed to be watertight or weathertight when assessing stability, freeboard and buoyancy in accordance with ISO 12217.

Description: The committee responsible for this document is ISO/TC 188, Small craft.
This second edition cancels and replaces the first edition (ISO 12215-5:2008, including its amendment ISO 12215-5:2008/Amd 1:2014), which has been technically revised.
One of the main reasons to achieve this revision, after a decade implementing the first edition, was to allow other scantlings calculation methods than those given in the 2008 edition, noting the huge development of finite element analysis methods and software, and the trend already applied in ISO 12215-9 (keels and appendages) and ISO 12215-7 (multihulls).
Therefore, in this new edition, like in many other scantlings standards, the design pressure loads, and the design stresses are given in the main body of the standard and, where needed, the scantlings calculation methods are detailed in Annexes.
The main changes compared to the previous edition are as follows:
— clarification of the scope and of many definitions, dimensions, and assessment;
— definition of a theoretical hull/deck limit height ZSDT in Table 3;
— renaming of nGC into kDYN in Table 7;
— lowering of the values of kL in the aft part of the craft in Table 8;
— deletion of kAR min, to better consider large panels, mainly sandwiches, in Table 9;
— improvement of the values of kSUP in Table 10;
— modification of design pressures for motor and sailing craft in Tables 12 & 13;
— modification of design stresses introducing kBB and kAM factors in Tables 15 to 17;
— incorporation of requirements for work boats in Table 2, Clause 12 and Annex J;
— possibility to use a wider range of assessment methods detailed in Table 18;
— move of the previous assessment method (now called "simplified") in Annex A;
Additional info: This document defines the dimensions, design local pressures, mechanical properties and design stresses for the scantlings determination of monohull small craft with a hull length (LH) or a load line length (see NOTE 1) of up to 24 m. It considers all parts of the craft that are assumed to be watertight or weathertight when assessing stability, freeboard and buoyancy in accordance with ISO 12217.
