Notes on Detailed Design 1

Project Organisation and

Documentation

INTRODUCTION
When a new offshore design and construction project gets under way, there is
obviously a great deal of organisation involved. A good, disciplined organisation
structure with clear, practical office procedures assists the engineers involved in
producing the design, selecting the materials and equipment and supervising the
construction. A detailed examination of design and construction office technical
documentation is beyond the scope of this book, but a brief discussion is provided
below for those not yet familiar with the subject.

TECHNICAL ORGANISATION OF THE DESIGN PROGRAMME
PROJECT PROCEDURES

The end product of any design office is to produce a set of documents which perform
the following functions:

1. A design document which fully describes the design of the new system. Each
stage of this description must be adequately supported by logical reasoning,
calculations and diagrams, sketches, etc.
2. A material list which identifies every material and equipment component (down
to the level of cable clips, nuts, bolts and washers, if need be).
3. An installation work scope document which fully describes in text, drawings,
schedules and diagrams how and in what sequence the equipment and material
are to be installed and commissioned.

This end product is not arrived at in one long session but is broken up in a series
of submissions or packages. The level of detail will also increase as the project
progresses.
Typically, this would occur as follows:

1. Conceptual or ‘front-end’ engineering study. This document should put forward
technical and economic arguments for and against the feasibility of various
alternative design schemes with recommendations as to which approach should
be adopted.
