...Doojin Jung; Sanghyun Kim In general, submarines are designed to optimize operation below the water surface because they spend most of their time underwater. On the other hand, the performance in the free surface condition is also important because submarines face a variety of scenarios to complete...

...Yucong Ma; Yihan Xing; Dan Sui A subsea shuttle tanker (SST) concept for liquid carbon dioxide transportation was recently proposed to support studies evaluating the ultra-efficient underwater cargo submarine concept. One important topic is the position keeping ability of SST during the offloading...

... shuttle and installation while they are connected in this manner. From a cost perspective, it is normally cheaper to utilize commonly used steel material in the construction of both outer and internal pressure hulls. In the construction of submarine pressure hulls, it is normal to use rolled steels...
