  • Multi-level structural modeling of an offshore wind turbine
    Francesco Petrini, Konstantinos Gkoumas, Wensong Zhou and Hui Li
    Abstract; Full Text (4054K)

Offshore wind turbines are complex structural and mechanical systems located in a highly demanding environment. This paper proposes a multi-level system approach for studying the structural behavior of the support structure of an offshore wind turbine. In accordance with this approach, a proper numerical modeling requires the adoption of a suitable technique in order to organize the qualitative and quantitative assessment in various sub-problems, which can be solved by means of sub-models at different levels of detail, both for the structural behavior and for the simulation of loads. Consequently, in a first place, the effects on the structural response induced by the uncertainty of the parameters used to describe the environmental actions and the finite element model of the structure are inquired. After that, a mesolevel FEM model of the blade is adopted in order to obtain the detailed load stress on the blade/hub connection.

Key Words
probabilistic analysis; performance-based design; uncertainty propagation; rotating blades

  • Modeling of non-isothermal CO2 particle leaked from pressurized source: I. Behavior of single bubble
    Daejun Chang, Sang Heon Han and Kyung-won Yang
    Abstract; Full Text (1430K)

This study investigated the behavior of a non-isothermal CO2 bubble formed through a leak process from a high-pressure source in a deep sea. Isenthalpic interpretation was employed to predict the state of the bubble just after the leak. Three modes of mass loss from the rising bubble were demonstrated: dissolution induced by mass transfer, condensation by heat transfer and phase separation by pressure decrease. A graphical interpretation of the last mode was provided in the pressure-enthalpy diagram. A threshold pressure (17.12 bar) was identified below which the last mode was no longer present. The second mode was as effective as the first for a bubble formed in deep water, leading to faster mass loss. To the contrary, only the first mode was active for a bubble formed in a shallow region. The third mode was insignificant for all cases.

CO2; bubble; depletion; dissolution; condensation; isenthalpic expansion

  • Modeling of non-isothermal CO2 particle leaked from pressurized source: II. Behavior of single droplet
    Daejun Chang, Sang Heon Han and Kyung-won Yang
    Abstract; Full Text (1474K)

This study revealed the behavior of droplets formed through leak process in deep water. There was a threshold depth named the universal attraction depth (UAD). Droplets rose upward in the zone below the UAD called the rising zone, and settled down in the zone above the UAD called the settling zone. Three mass loss modes were identified and formulated: dissolution induced by mass transfer, condensation by heat transfer and phase separation by pressure decrease. The first two were active for the settling zone, and all the three were effective for the rising zone. In consequence, the life time of the droplets in the rising zone was far shorter than that of the droplets in the settling zone.

Key Words
CO2; droplet; depletion; universal attraction depth (UAD); dissolution; condensation; isenthalpic expansion

    Abstract; Full Text (3546K)

In this paper, an offshore process front end engineering design (FEED) method is systematically introduced and reviewed to enable efficient offshore oil and gas production plant engineering. An integrated process engineering environment is also presented for the topside systems of a liquefied natural gas floating production, storage, and offloading (LNG FPSO) unit, based on the concepts and procedures for the process FEED of general offshore production plants. Various activities of the general process FEED scheme are first summarized, and then the offshore process FEED method, which is applicable to all types of offshore oil and gas production plants, is presented. The integrated process engineering environment is presented according to the aforementioned FEED method. Finally, the offshore process FEED method is applied to the topside systems of an LNG FPSO in order to verify the validity and applicability of the FEED method.

Key Words

  • Reducing hydroelastic response of very large floating structures by altering their plan shapes
    Z.Y. Tay and C.M. Wang
    Abstract; Full Text (3233K)

Presented herein is a study on reducing the hydroelastic response of very large floating structures (VLFS) by altering their plan shapes. Two different categories of VLFS geometries are considered. The first category comprises longish VLFSs with different fore/aft end shapes but keeping their aspect ratios constant. The second category comprises various polygonal VLFS plan shapes that are confined within a square boundary or a circle. For the hydroelastic analysis, the water is modeled as an ideal fluid and its motion is assumed to be irrotational so that a velocity potential exists. The VLFS is modeled as a plate by adopting the Mindlin plate theory. The VLFS is assumed to be placed in a channel or river so that only the head sea condition is considered. The results show that the hydroleastic response of the VLFS could be significantly reduced by altering its plan shape.

Key Words
very large floating structure (VLFS); geometries; arbitrary shapes; mitigation methods; hydroelastic response

    Research and Publication Ethics

    All the editors, publishers, researchers, and peer reviewers of Techno-Press journals strongly encourage to carefully review and follow the Committee on Publication Ethics (COPE) guidelines:

    1. Authorship
    Authorship credit should be based on
        (1) Substantial contributors to the conception or design of the work or the acquisition, analysis
       or interpretation of data for the work,
        (2) Drafting the work or revising it critically for important intellectual content,
        (3) Final approval of the version to be published, and
        (4) Agreement to be accountable for all aspects of the work in ensuring that questions related
       to the accuracy or integrity of any part of the work are appropriately investigated and resolved.
    Authors should meet these four conditions after the initial submission of a manuscript and any changes whatsoever in authorship (adding author(s), deleting author(s), or re-arranging the order of authors) must be explained by a letter to the editor from the authors concerned. This letter must be signed by all authors on the paper. Techno-Press does not correct authorship after the final acceptance unless a mistake has been made by the editorial staff. Authorship may be changed before the final acceptance when the authorship correction is requested by all of the authors involved with the manuscript. The corresponding author takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process. The corresponding author should be available throughout the submission and peer review process to respond to editorial queries in a timely manner, and should be available to respond to critiques of the work and cooperate with any requests from the journal for data or additional information or questions about the paper even after publication.

    2. Originality, plagiarism and duplicate publication
    Submitted manuscripts must not have been previously published or be under consideration for publication elsewhere. No part of the accepted manuscript should be duplicated in any other journal without the permission of the Editorial Board. Submitted manuscripts are checked for possible plagiarism or duplicate publication upon the paper's arrival. If plagiarism or duplicate publication is detected, the manuscripts may be rejected, the authors will be announced in the journal, and their institutions will be informed. There will also be penalties for the authors. A letter of permission is required for any and all material that has been published previously. It is the responsibility of the author to request permission from the publisher for any material that is being reproduced. This requirement applies to text, figures, and tables.

    3. Conflict of interest statement
    The corresponding author must inform the editor of any potential conflicts of interest that could influence the authors' interpretation of the data. Examples of potential conflicts of interest are financial support from or connections to companies, political pressure from interest groups, and academically related issues. In particular, all sources of funding applicable to the study should be explicitly stated.

    4. Process for managing research and publication misconduct
    When the journal faces suspected cases of research and publication misconduct, such as redundant publication, plagiarism, fraudulent or fabricated data, changes in authorship, undisclosed conflict of interest, ethical problems with a submitted manuscript, appropriation by a reviewer of an author's idea or data, and complaints against editors, the resolution process will follow the flowchart provided by COPE,
    The discussion and decision on the suspected cases are carried out by the Editorial Board.

    5. Editorial responsibilities
    The Editorial Board will continuously work to monitor and safeguard publication ethics:
    * Guidelines for retracting articles;
    * Maintenance of the integrity of academic records;
    * Preclusion of business needs from compromising intellectual and ethical standards;
    * Publishing corrections, clarifications, retractions, and apologies when needed; and
    * Excluding plagiarized and fraudulent data.
    The editors maintain the following responsibilities:
    * Responsibility and authority to reject and accept articles;
    * Avoid any conflict of interest with respect to articles they reject or accept;
    * Promote the publication of corrections or retractions when errors are found; and
    * Preserve the anonymity of reviewers.
