摘要

西非近海的海洋环境被认为是温和的。然而，在南方冬季和夏季，来自遥远的南北大西洋产生的涌浪可以达到相对低波周期的高波幅值或长波周期的低波幅值，后者在评估船舶共振时可能是一个重要的考虑场景。大多数海上作业，包括西非的海上钻井和安装，都是通过浮式系统进行的。这些系统的响应和性能受诸如波浪和涌浪的振幅和频率等特性的支配。因此，充分了解尼日利亚近海的海况非常重要。本研究利用定位在尼日利亚海岸外Bonga站点的定向载波器(DWR)收集的Bonga近海波浪测量数据，涵盖了尼日利亚近海涌浪海的描述。

Swell description for Bonga offshore Nigeria location

The ocean environment offshore West Africa is considered to be mild. However, the generated swell from distant North and South Atlantic during austral winter and summer can reach high wave amplitudes with relatively low wave periods or low wave amplitudes with long wave periods, the later can be a crucial scenario to consider when the assessment of vessel resonance is of importance. Most offshore operations, which include offshore drilling, and installation in West Africa, are carried out from floating systems. The response of these systems and performance are governed by characteristics, such as amplitude and frequency of the wave and swell seas. It is therefore important to fully understand the sea conditions offshore Nigeria. This study covers the description of the swell sea offshore Nigeria using Bonga offshore wave measurements collected from the directional wave-rider (DWR), positioned at the Bonga site off the coast of Nigeria.
