Design Methodologies

The floating offshore wind turbine (FOWT) market is currently dominated by single unit demonstration projects and first pre-commercial wind farms such as the Hywind Scotland wind farm. Today’s FOWT substructure design process is therefore not yet at a level of industrialization comparable to fixed-bottom substructure design methodologies, where standardized design and realization procedures are well established throughout the industry. Aligned with work performed in the Ramboll and University of Stuttgart-led work packages “Concept Industrialization” and “Design practice” of the European H2020 LIFES50+ project, the ambition of this paper is to define state-of-the-art fixed-bottom and floating design methods and based on these identify key differences through comparative analysis. In the first part of the paper the scope and selected details of today’s industrialized design process for fixed-bottom substructure design is presented, including e.g. load iteration schemes and applied numerical methods, risk assessment incorporation, optimization, and cost modelling. In the second part, the key elements of this industrialized procedure which are different to FOWT design are identified and described: This is done based on a review of the current FOWT common design practice, where elements are identified that are unique and/or different for FOWTs — this includes e.g. the requirement to adapt the controller to the specific platform behaviour, as well as a tower and/or selected rotor-nacelle assembly (RNA) component redesign, and also includes differences in terms of defining and performing load case simulations. Another observation that is described relates to the floating specific required numerical methodologies applied for the detailed structural and mooring design, where challenges exist regarding the interface between coupled global loads analyses tools and detailed structural, mooring, and geotechnical tools. A further key item discussed in this respect is the industry-common load exchange practice for fixed-bottom design, where only a limited data exchange between WT manufacturers and platform designers is done; a procedure that is challenging to be applied for FOWTs. Compared with fixed-bottom design, the consideration of manufacturability, fabrication constraints, serial production, design complexity reduction, assembly, supply chain, installation, geotechnics, O&M and risk is often limited and these items will also be briefly discussed. Overall the paper is intended as a technical review of existing fixed-bottom design procedures and, facilitated through the comparative analysis with these established design methodologies, identifies and presents the key differentiating design elements and challenges for an industrialized FOWT design. The content of the paper will provide input for the focused development of design processes for industrialized detailed design of FOWTs to guarantee the demanded technology-readiness and manufacturing-readiness levels (TRL and MRL) and ultimately improve their CAPEX and OPEX by applying industrial design procedures.

Time Of Troubles

Introduction. To study the peasantry of the 16th – the early 17th century in Russia we need information from all the territories of the state. There are unique documents in the archives of the Joseph-Volokolamsk monastery for the central part of the Russian state, which allow us to investigate the issue of monastic enslavement. This issue has not been studied enough regarding the early 17th century. Methods and materials. Such a source as a borrowed monastic bondage is poorly studied in historiography. In this regard the aim of the article is to study the position of monastery borrowers according to the form of debt records of the early 17th century. There are objectives: to identify the elements of the form of bondage records that reflect the position of the borrowers; to consider changes in the position of borrowers based on the debt book form evolution. The article uses the methods of formal and comparative analysis with respect to records in debt books of 7115 (1606/07), 7116 (1607/08), the bondage book of 1609, and borrowed bondages of 1609. Analysis. The records of money issuance debt books of 1606/07 and 1607/08 were compared with the information from the debt book of 1532-1534. The author traced the evolution of debt charging book design elements based on the sources of 1606/07 and 1607/08. The paper analyzes borrowed bondages of besieged people on borrowed monastery bread in 1609, along with the bondage book of 1609. These results were compared with the bread bondages of the Spaso-Prilutsky monastery. Results. The form of debt records has been well developed by the early 17th century. According to money issuance and charge records, a borrower was protected from lender’s abuses. However, bread bondages most objectively reflect the position of a debtor, who was in danger of enslavement because of vague wording in bondages.

Definition Of

A modern roundabout is an intersection with a circulatory roadway at which the vehicle speed is low, and the traffic is continuous and circulating in one direction around the central island towards the exits at the approach legs. Modern roundabout design is an iterative process that is composed of the following steps: (1) the identification of the roundabout as the optimal traffic solution; (2) the definition of the number of lanes at the intersection based on the required capacity and the level of service; (3) the initial design of the roundabout geometry; (4) design vehicle swept path, the fastest path analysis, and visibility performance checks; and (5) detailed roundabout design if the results of the performance checks are in line with the design recommendations. Initial roundabout geometry design elements are not independent of each other; therefore, care must be taken to provide compatibility between them. An overview and a comparative analysis of the initial geometric design elements for suburban single-lane roundabouts defined in roundabout design guidelines and norms used in Croatia, Austria, France, the Netherlands, Germany, Serbia, and Switzerland is given in this entry.
