2.1 The Rules
and Regulations for the Classification of Special Service Craft (hereinafter
referred to as the Rules for Special Service Craft) provide scantling
requirements for a basic structural configuration for both mono and
multi-hull craft with multi-deck or single deck hulls which include
a double bottom, or single bottom arrangement. The structural configuration
may also include a single or multiple arrangement of cargo hatch openings.
The Rules for Special Service Craft provide for both longitudinal
and transverse framing systems. Alternative types of framing systems
will be specially considered on the basis of the Rules for Special
Service Craft.
2.2 Every effort
has been taken to make the Rules for Special Service Craft scantling
formulae as transparent as possible, and to achieve this objective
the following approach has been adopted:
- lay down requirements,
- specify modelling considerations,
- indicate limit states,
- state constraints in an explicit manner.
2.3 This approach
will enable the designers and Builders to decide for themselves the
suitability of the Rules for Special Service Craft for their project.
Further and perhaps more importantly changes may be easily made to
the requirements based upon experience gained, discussions with interested
parties and as development progresses. This is similar to the current
Rule development process which is continually updating and 'tailoring'
Rules requirements.
