The stages of design
start with a concept, gradually working our way deeper into the design,
then finally perfecting details.
The design process of a new yacht is typically divided into three
1. First stage is the Concept Design.
The yacht’s basic lay-out is drawn without details and calculation in order
to give the client a basic insight into the project. It is an exchange of ideas,
to see what they look like when put on paper. If the concept complies with the
client’s wishes, then we can move forward to the second stage.
2. The second stage is the Preliminary
At this stage the design is further developed, without going
too deep into details.
The Preliminary Design stage has two purposes.
To develop the design with correct dimensions and proportions and in addition,
to provide insight of compliance with the principle classification and flag
B. To produce documentation to enable experienced
shipyards to quote.
The documentation produced contains the following
- An update and consolidation of the preliminary General Arrangement Plan
- Preliminary Lines Plan Hull
- Preliminary Tank plan
- Preliminary Stability Calculation (intact)
- Preliminary Damaged Stability Calculations
- Preliminary Resistance and Power estimation
- Preliminary selection of main engines and propulsion system
- Preliminary calculating and drawing of the structure basic system
- Building specifications.
3.The third stage is the Final Design.
At this stage design drawings and other documentation is produced for the
yard that has been assigned for the build. In comparison to the first two, this
stage is far more comprehensive. It contains the production of detailed
drawings, reports, yard visits etc.
Among the drawings produced are:
After launching, the final stability booklet can be put together, for
which an inclination test is conducted to determine the weight and the position
of the centre of gravity. In other words, the final design stage, follows the
build through the sea trial until the delivery of the vessel to the owner.
