“…Hence, such comparison will provide a better understanding of suitability of WAAM-built components for marine renewable energy applications. The uniaxial fatigue data which were used for comparison include: the data obtained from large dog bone S355 specimens tested at R = 0.1 tested by Anandavijayan et al [34], the data from smaller dog bone S355 specimens examined at R = − 1 by Corigliano et al [35], the data from round bar S355 specimens assessed at R = 0.01 by Dantas et al [36] and at R = − 1 by Aeran et al [37], and finally the data from fillet welded cruciform S355 specimens tested at R = 0 by Berto et al [38]. The S-N curve, generated for wrought cylindrical C40 carbon steel specimens at R = − 1 by Atzori et al [39] was also included into the comparison with the literature data.…”

The aim of this work was to examine uniaxial, torsion, and multi-axial fatigue characteristics of ER100S-1 low carbon steel specimens fabricated with wire arc additive manufacturing (WAAM) technique, a subcategory of directed energy deposition (DED). Two distinct specimen orientations were tested—vertical and horizontal, extracted perpendicular and parallel to the WAAM deposited layers, respectively. Fracture surfaces of the tested specimens were analysed under scanning electron microscope (SEM) to observe fracture mechanisms corresponding to different specimen orientations, different fatigue loading conditions, and to interpret the fatigue results obtained from the tests. Finally, the obtained stress–life results were compared with the fatigue data available in the literature for a series of wrought and WAAM-built structural steel specimens. Moreover, the S–N curves obtained in this study were evaluated against the fatigue design curve recommended for offshore marine welded structures in DNV standard. Test results have shown advantageous characteristics of WAAM-built ER100S-1 specimens compared with behaviours of other structural steels and conservative prediction of its fatigue life by the design curve available in the DNV standard.

“…Alternative searches (Table 3) rendering significant results are "fatigue life" (190 publications) and "remaining life" (17), suggesting that these are more common terms than "lifetime extension" within the offshore wind community. An initial exploration suggests that the terms are related but not synonymous, with fatigue and remaining life investigating the durability aspects, though not for lifetime extension in particular (e.g., [196][197][198]). The term "derating" also returned ten search results.…”

Circular economy and renewable energy infrastructure such as offshore wind farms are often assumed to be developed in synergy as part of sustainable transitions. Offshore wind is among the preferred technologies for low-carbon energy. Deployment is forecast to accelerate over ten times faster than onshore wind between 2021 and 2025, while the first generation of offshore wind turbines is about to be decommissioned. However, the growing scale of offshore wind brings new sustainability challenges. Many of the challenges are circular economy-related, such as increasing resource exploitation and competition and underdeveloped end-of-use solutions for decommissioned components and materials. However, circular economy is not yet commonly and systematically applied to offshore wind. Circular economy is a whole system approach aiming to make better use of products, components and materials throughout their consecutive lifecycles. The purpose of this study is to enable the integration of a sustainable circular economy into the design, development, operation and end-of-use management of offshore wind infrastructure. This will require a holistic overview of potential circular economy strategies that apply to offshore wind, because focus on no, or a subset of, circular solutions would open the sector to the risk of unintended consequences, such as replacing carbon impacts with water pollution, and short-term private cost savings with long-term bills for taxpayers. This study starts with a systematic review of circular economy and wind literature as a basis for the coproduction of a framework to embed a sustainable circular economy throughout the lifecycle of offshore wind energy infrastructure, resulting in eighteen strategies: design for circular economy, data and information, recertification, dematerialisation, waste prevention, modularisation, maintenance and repair, reuse and repurpose, refurbish and remanufacturing, lifetime extension, repowering, decommissioning, site recovery, disassembly, recycling, energy recovery, landfill and re-mining. An initial baseline review for each strategy is included. The application and transferability of the framework to other energy sectors, such as oil and gas and onshore wind, are discussed. This article concludes with an agenda for research and innovation and actions to take by industry and government.

“…Steel structural elements and constructions are frequently subjected to varying loads over their service (fatigue) lives [5,6]. Due to the nature of their sufficient qualities and inexpensive prices, structural steels S235 [7], S275 [8], and S355 [9,10] are the most extensively used steels for structural elements and constructions exposed to fatigue stress [11]. High-strength steel [12] is used in order to meet the requirements for light constructions with simple designs while having excellent structural performance.…”

“…The S-N curves proposed in the design regulations EN 1993-1-9 [13] and EN 13001-3-1 [14] do not reveal the exact material dependence; hence, the exact fatigue properties of different steel types must be determined. In general, the fatigue behavior of structural steels is well-understood and investigated by many researchers [9,10,15], but high-strength steels are still understudied, and determining their mechanical properties (fatigue) has become the particular focus of several researchers [16][17][18][19].…”

Steel of the mild-strength S355J2+N steel grade is the most often used steel for manufacturing carrying sections of constructions exposed to fatigue loads. The use of high-strength steels, such as S690QL, allows for the creation of structures that are light and simple to construct. However, increasing the yield strength of high-strength steels does not result in a corresponding increase in fatigue resistance. As a result, using high-strength steels for constructions subjected to fatigue loading can be a major design concern, raising the question of whether high-strength steels should be used at all. Most of the experimental investigations regarding the hot work tool steel X37CrMoV5-1 found in the literature are focused on its machining and wear resistance, with insufficient attention paid to the cyclic loads. This article evaluates the fatigue properties of mild-strength S355J2+N, high-strength S690QL, and X37CrMoV5-1 steel grades. A SHIMADZU servo-hydraulic testing machine is used to perform uniaxial tensile tests under uniaxial fatigue stress-controlled, fully reversed conditions (tensile–compression testing with R = −1 stress ratio) in accordance with EN ISO and ASTM standards. The aim of this paper is to highlight the fatigue characteristics of these three steels that are among the most used in their respective groups. Steel S355J2+N belongs to the group of hot-rolled normalized steels, S690QL belongs to the group of improved (quenched + tempered) steels with increased strength, and X37CrMoV5-1 belongs to the group of high-alloyed tool steels for hot work. This choice was made as the tested steels can be considered typical representatives of their groups. Based on the test results of these three steels, which are organized in S–N curves, the fatigue behavior of the entire mentioned groups of steels can be foreseen.
