Abstract

In the design process of offshore steel structures, it is typical to employ commercial calculation codes in which simulation
and evaluation of results are performed on the basis of the available standards (e.g. API, DNV, Lloyds). The modeling
and solution rely on finite element methods and cover the simulation of the structure’s properties along with the influence
of the marine environment – sea currents, wave and wind loading, as well as the influence of vibrations, buoyancy and
accompanying mass of water. Both commercial and open source mathematical modeling software which is available
nowadays allows for cost effective and flexible implementation of advanced models for offshore industrial structures
with high level of credibility and safety. The models can be built to suit task-specific requirements and evaluated on the
basis of the selected criterial system best suited to the needs of the customer. Examples of methodology for environmental
and structural model development are presented, along with simulation results covering a wide scope of data, ranging
from stress and deformation to resonant characteristics and issues of technological feasibility.
