3.3 Basic Design of a Fixed Jacket-/Tower-type Offshore Platform
The composition of these platforms is shown in the figure 3.8.

Deck - supports the drilling and production equipment and life support systems
of the platform. A number of offshore platform deck types have evolved in
response to operational requirements and the fabrication infrastructure and
installation equipment availability.
Operational requirements dictate the general deck size and configuration
(number of deck levels and their layout, etc.). For example, need for a fully
integrated drilling and production system would dictate vertical and horizontal
layering of the deck structure in such a manner as to provide an efficient operation
while also providing an acceptable level of human and environmental safety.
An integrated deck may be divided into a number of levels and areas
depending on the functions they support. Typical levels are:
