Concept design

GL Garrad Hassan's design experts are highly experienced at assisting clients through the Concept Design phase. They will help to establish a client's main design requirements, key parameter values, overall layout, and, where possible, they will also select major component sizes and ratings and, in certain key areas, the component supplier.

The ouput of the concept design phase always includes a concept layout in CAD form, as well as all the necessary information required for the subsequent preliminary design phase.

The concept design process typically commences with a kick-off meeting, to formalise the concept requirements. Development of the control and safety concept is followed by the creation of a preliminary mathematical model, which establishes baseline loading information for selection of critical components. The concept is then developed by considering the system layout and reviewing the availability and capability of key design driving components. After this, a draft Concept Design Specification document is prepared, which provides both a detailed description and a CAD model of the initial system layout. These are formally reviewed with the client, before finalisation of the Concept Design Specification, which includes:

 

Basic design parameters

Required design standard and certification rules

Definition of control and safety equipment

Baseline loads

Key component and sub-system selection and definition

Power take off system

Layout and general outline of all major structures and bearings

Dimensions and mass estimates of major components
