Section 3 Structural Design Assessment, SDA

3.1 Structural Design Assessment notation – SDA

3.1.1 The SDA procedure is an optional procedure and is applied on a voluntary basis when an Owner or designer seeks to increase confidence levels in the structural integrity of a ship.

3.1.2 The ship structure is to be examined using finite plate element methods to assess both the overall and detailed structural capability to withstand static and dynamic loadings.

3.1.3 The SDA procedure is in addition to the normal Rule structural design approval requirements specified within Vol 1, Pt 6, Ch 3 Scantling Determination.

3.1.4 The SDA procedure may be mandatory for very structurally complex ships. For complex ships, the ship designer is to supply outline details of the ship to LR at an early stage in the design in order that agreement can be reached on the appropriate level of analysis required.

3.1.5 Where applicable, the ship structure is to be examined for the structural capability to withstand dynamic loadings from partially filled tanks or the influence of thermal loadings.
