Review of Deep-Ocean High-Pressure Simulation Systems

Abstract

AbstractDeep-sea technology and equipment are required to explore the oceans and utilize ocean resources in the 21st century. Deep-ocean simulation systems (DOSs) play an essential role in the development of deep-sea equipment. This paper gives a detailed overview of deep-ocean high-pressure simulation systems (DOHPSs) worldwide. First, the history of DOS is introduced, and then the primary available equipment, particularly coming out of China, is described. Next, the new concept of the cold isostatic pressing (CIP) chamber and its technology and equipment are reviewed. Then, the basic mathematical theory for the design of pressure chambers is introduced to illustrate the limitations of the traditional monobloc chamber. To easily understand the pre-stressed wire-wound (PSWW) design, the pre-stress coefficient is introduced in theoretical analysis. Some valuable researches of PSWW are presented. Finally, the sealing design of DOS, especially tooth-locked quick-actuating closures (TLQAC), is discussed. The paper aims to inspire readers to develop innovative ideas about the future design of DOS.
