The structure is modelled using PREFRAME (DNV (1984a)).
Sesam software for offshore wind turbine foundation design and analysis is based on decades of experience in engineering of offshore structures. It provides a tailor-made solution for structural strength analysis of fixed and floating offshore wind support structures, such as wind turbine jackets, floating platforms, and substations. Some results are removed in response to a notice of local law requirement. For more information, please see here.
Wikipedia: a vertically moored floating structure normally used for the offshore production of oil or gas, and is particularly suited for water depths greater than 300 meters (about 1000 ft) and less than 1500 meters (about 4900 ft).
The economic feasibility of an offshore project depends on many aspects: capital expenditure (CAPEX), tax, royalties, operational expenditure (OPEX). In a typical offshore field development, one third of the CAPEX is spent on the platform, one third on the drilling of wells and one third on the pipelines.
SIM is a process for ensuring the fitness for purpose of an offshore structure from installation through to decommissioning. The process is a rational means for understanding the effects of degradation, damage, changes in loading, accidental overloading, changes in use, life extension, and the evolution of offshore design practice.
Slamming, violent impact on offshore structures, is a strongly nonlinear phenomenon involving the interaction among water, air and structure. Slamming forces are affected by various factors, such as compressibility of water, hydroelasticity of the structure, air bubbles entrapped, cavitation and
Design of offshore steel structures, general - LRFD method DNV GL AS CHAPTER 1 INTRODUCTION SECTION 1 INTRODUCTION 1 General 1.1 Introduction 1.1.1 This offshore standard provides principles, technical requirements and guidance for the structural design of offshore structures. 1.1.2 DNVGL-OS-C101 is the general part of the DNV GL offshore standards for structures. The design
