While many countries and international organizations with maritime security interests and rights at sea have developed new security strategies or policies in the wake of the 9/11 terrorist attacks in the United States of America, they have accordingly changed or created new maritime security strategies or doctrines with appropriate Maritime Situational Awareness (MSA) models as well. Maritime deterioration, climate change, cyberattacks, serious and organized crime, epidemics, and state-made threats are just some of the new and growing concerns affecting maritime security. The sabotage of the Nord Stream gas pipelines in the Baltic Sea has given maritime security doctrines and frameworks a new dimension. In this article, the current maritime security approaches and maritime domain or situational awareness (MDA/MSA) model examples of some countries and international organizations from different geographic regions and also the ones that are located in the maritime choke point regions where global maritime trade routes are located and also the effects of the Nord Stream Pipelines sabotages on these are examined in light of the new threats and risks. The principle result reached in this study is that countries and international structures should have a cross governmental maritime security strategy, or at least a doctrine, in order to guide their own maritime situational awareness models and identify information sharing architectures. The most important result of the sabotages on Nord Stream Pipelines for MSA models in this study is that the fastest and most cost-effective method for protecting critical infrastructure under the seas is the concept of systems such as Mothership controlled autonomous and unmanned underwater vehicles, extra large unmanned undersea vehicles and Synthetic-aperture radar (SAR) satellites.

美国9/11恐怖袭击事件后，许多拥有海上安全利益和权利的国家和国际组织制定了新的安全战略或政策，并相应改变或创造了新的海上安全战略或学说。以及适当的海事态势感知（MSA）模型。海事恶化、气候变化、网络攻击、严重的有组织犯罪、流行病和国家制造的威胁只是影响海事安全的新的、日益严重的问题中的一些。波罗的海北溪天然气管道的破坏给海上安全理论和框架带来了新的维度。在本文中，来自不同地理区域以及位于全球海上贸易路线所在的海上咽喉点地区的一些国家和国际组织的当前海上安全方法和海域或态势感知（MDA/MSA）模型示例根据新的威胁和风险，研究了北溪管道破坏对这些的影响。本研究得出的主要结果是，国家和国际机构应该制定跨政府的海上安全战略，或者至少是一种学说，以指导自己的海上态势感知模型并确定信息共享架构。
