“…Hence the contractor must get adequate information about the platform's details-dimensions, weights, prices of materials, and cost of labour. The knowledge of experienced Project Engineers and Project Managers is very crucial, which helps to achieve different developed facilities, ranging from semisubmersibles [218][219][220][221][222][223][224][225][226][227][228] to FPSOs [229][230][231][232][233][234] and offshore wind turbines [235][236][237][238][239][240].…”

“…By rough estimates, an offshore platform that weight around 30,000 t could cost around 350-500 million dollars, plus another 60-120 million dollars for three tugboats. However, there are various studies that cover the accounting and costing of oil facilities and the financial aspect of project management [240][241][242][243][244][245][246][247][248][249][250][251].…”

Offshore structures exist in a variety of forms, and they are used for a variety of functions in varied sea depths. These structures are tailored for certain environments and sea depths. Different actions for suitable equipment selection, platform type design, and drilling/production processes are required for the applications of these offshore structures, as given in Part I. This paper is the second part, which outlines various processes, loads, design approaches and project management of offshore platforms. To achieve these, proper planning must be conducted for lifting, transportation, installation, design, fabrication, and commissioning of these offshore platforms. Some historical developments of some offshore structures are presented, and some project planning routines are undertaken in this research. The ultimate goal is to provide a general overview of the many processes of offshore platform design, construction, loadout, transportation, and installation. Some discussions on the design parameters such as water depth and environmental conditions were presented. It also lists various software programs used in engineering designs. The review also includes information on cutting-edge offshore platforms and industry advancements. Ultimately, for long-term operations, various types of offshore platforms for specific seawater depths are available.

“…The predominant type of offshore wind farm at global level is the bottom-fixed wind turbine in shallow water (Pantusa et al, 2020). However, floating wind turbines are a more promising solution for offshore situations, since they can be installed with sea depths ranging from 50 to 500 m (Pantusa and Tomasicchio, 2019;Poujol et al, 2020).…”

Benchmarking Marine Energy Technologies Through LCA: Offshore Floating Wind Farms in the Mediterranean

et al. 2022

Floating wind turbines are a valid option for offshore wind farms in the Mediterranean, where the sea-floor falls off rapidly with distance from the coastline. The present study concerns a Life Cycle Assessment of the environmental performance of two types of floating wind turbine. Greenhouse gas emissions of two standard models (raft-buoy and spar-buoy, 154 m rotor diameter, 6 MW installed power) were estimated in terms of Global Warming Potential (t CO2eq) with the aim of determining a benchmark for evaluating the performance of similar offshore wind farms. Thus, the aim of the paper was to create a benchmark for the design of innovative technologies, such as those developed by specialist companies, and to verify the validity of new designs and technologies in terms of avoided greenhouse gas emissions. The results show that the Carbon Intensity of Electricity of a single floating wind turbine varies in the range 26–79 g CO2eq·kWh−1, averaging 49 g CO2eq·kWh−1, in line with other studies of offshore wind turbines and other renewable energy sources (such as onshore wind and photovoltaic). Extension of our study to the whole life cycle, including manufacturing, assembly and installation, maintenance and material replacement and a hypothetical decommissioning and end-of-life, showed that wind farms are among the most promising marine renewable energy technologies for the Mediterranean.

“…Europe's floating wind fleet is the largest worldwide (70%) producing a total of 45 MW by the end of 2019 [4]. Demonstration projects have tested different floating concepts [6], sometimes associating wind turbines with wave energy converters [7][8][9] with the objective to reducing costs or upscaling previous modelscale devices. However, in other countries, the feasibility of this type of device has been evaluated [10,11].…”

Dynamic Loads and Response of a Spar Buoy Wind Turbine with Pitch-Controlled Rotating Blades: An Experimental Study

et al. 2021

View full text Add to dashboard Cite

New large-scale laboratory data are presented on a physical model of a spar buoy wind turbine with angular motion of control surfaces implemented (pitch control). The peculiarity of this type of rotating blade represents an essential aspect when studying floating offshore wind structures. Experiments were designed specifically to compare different operational environmental conditions in terms of wave steepness and wind speed. Results discussed here were derived from an analysis of only a part of the whole dataset. Consistent with recent small-scale experiments, data clearly show that the waves contributed to most of the model motions and mooring loads. A significant nonlinear behavior for sway, roll and yaw has been detected, whereas an increase in the wave period makes the wind speed less influential for surge, heave and pitch. In general, as the steepness increases, the oscillations decrease. However, higher wind speed does not mean greater platform motions. Data also indicate a significant role of the blade rotation in the turbine thrust, nacelle dynamic forces and power in six degrees of freedom. Certain pairs of wind speed-wave steepness are particularly unfavorable, since the first harmonic of the rotor (coupled to the first wave harmonic) causes the thrust force to be larger than that in more energetic sea states. The experiments suggest that the inclusion of pitch-controlled, variable-speed blades in physical (and numerical) tests on such types of structures is crucial, highlighting the importance of pitch motion as an important design factor.
