DNV GL ANALYSIS TECHNIQUES V-2-1 PDF

Purpose 

These Guidelines address the application of the process of analysing safety equivalency for alternative designs and arrangements for individual design solutions, as outlined in aforementioned IMO circulars. 

These Guidelines are not intended to be applied to obtain type approval of individual materials, components or portable equipment. 

The objectives of these Guidelines are:

− with regard to owners, yards and designers: to provide an overview on the objectives and working tasks of the alternative design process

− with regard to designers: to provide technical recommendations considering the implementation of individual process steps

− with regard to yards: to provide recommendations on the implementation of the alternative design process 

The process of alternative design analysis – as is described in these Guidelines – is based on a holistic risk assessment. This approach is recommended by Germanischer Lloyd (GL), because of its benefits with respect to the quality and safety of the design. It is acknowledged that other approaches may also be acceptable to demonstrate compliance with the requirements set out in MSC/Circ. 1002 and MSC.1/Circ. 1212. The extent to which each step of the risk assessment is to be elaborated depends on the individual application and should be agreed with the responsible Administration in each case. 

It is highly recommended to read these Guidelines completely prior to commencing the process of analysing safety equivalency for alternative designs and arrangements.
