Secondary steel design

The definition “secondary steel” comes from the traditional offshore engineering widely used within common rules and guidelines. The idiom was introduced to characterize requirements to metallic materials due to their mechanical load situation. In former German Lloyds rules we red: These are all structural members of minor significance exposed to minor stresses only, and not coming under the above categories of “special” and “primary”. In project circumstances the secondary steel covers all functional attachments at the entire structure. It provides a variety of functions with HSE and performance aspects. The attachments frequently feed back to the global design in different effects.

OWT is used to design these functional attachments meeting employers requirements and evaluating their impact to the dynamic behaviour of the entire structure. It is a kind of our credo to recognize the full significance of the “secondary steel” and to find feasible solutions.
