Offshore wind farms have emerged as an effective method for responding to the energy crisis. However, offshore wind power generation has been indiscriminately planned at sea, leading to interference with the traffic routes of merchant ships. Many countries and organisations have set buffer zone standards to ensure the safe navigation of passing vessels, but these standards differ widely. As a typical example, the standards of the International Maritime Organization (IMO) and those of the Confederation of European Shipmasters’ Associations (CESMA) are used to decide the route widths of vessels; however, they both have limitations, preventing their application to all sea areas. This study proposes a novel methodology to calculate the width of a route using distribution and line density analyses of 90% and 50% maritime traffic. First, four categorised maritime routes and gate lines are established to comparatively analyse the width of maritime traffic routes. Next, to ensure reliability-based route safety, the compliance of extracted maritime traffic route widths with the criteria established by the IMO and CESMA is verified. The selection of optimised widths for vessel traffic routes will ensure the safe navigation of maritime traffic and encourage the sustainable development of maritime spaces.

海上风电场已成为应对能源危机的有效手段。然而，海上风力发电却在海上乱规划，导致商船航行路线受到干扰。许多国家和组织都制定了缓冲区标准，以确保过往船只安全航行，但这些标准差异很大。典型的例子是，船舶航线宽度采用国际海事组织（IMO）和欧洲船长协会联合会（CESMA）的标准；然而，它们都有局限性，无法应用于所有海域。本研究提出了一种利用 90% 和 50% 海上交通的分布和线路密度分析来计算路线宽度的新颖方法。第一的，建立四类海上航线和门线，对海上交通航线的宽度进行比较分析。接下来，为了确保基于可靠性的航线安全，验证提取的海上交通航线宽度是否符合 IMO 和 CESMA 制定的标准。船舶交通航线优化宽度的选择，将保障海上交通的安全航行，促进海域的可持续发展。
