ABSTRACT

Collisions frequently occur at sea, leading to serious human injury, and damage to property and the environment. Furthermore, the increasing number of offshore platforms means that collisions between vessels and offshore structures are a frequent type of accident. Platforms are at a greater risk of collisions than ships, because they have no avoidance capability when operating. Recently, the expansion of offshore wind farms in response to new green energy requirements has led to wind-turbine installation vessels (WTIVs) being in common use. WTIVs are similar to fixed jack-up rigs, and they are self-propelled because they must be able to quickly relocate during wind-farm operation. Therefore, it is important to consider the operational characteristics of WTIVs when calculating their collision risks. This study develops a new method for analysing WTIV collision frequency and then compares the proposed method with the existing methods. It also discusses the implications of the methods for ship-WTIV collision-frequency analysis.

摘要

碰撞经常发生在海上，导致严重的人身伤害，并对财产和环境造成破坏。此外，越来越多的海上平台意味着船舶与海上结构之间的碰撞是常见的事故类型。平台比船舶面临更大的碰撞风险，因为平台在操作时没有回避能力。最近，为响应新的绿色能源需求，海上风电场的扩张导致了风力涡轮机安装船（WTIV）的普遍使用。WTIV与固定式自升式钻机类似，它们是自推进式的，因为它们必须能够在风电场运行期间快速迁移。因此，重要的是在计算WTIV的碰撞风险时考虑其运行特性。这项研究开发了一种新的分析WTIV碰撞频率的方法，然后将该方法与现有方法进行了比较。它还讨论了舰载WTIV碰撞频率分析方法的含义。
