Underwater Connecting Apparatuses and Assemblies

摘要

Underwater connecting apparatuses include a flexible diaphragm that at least in part defines a wall of a chamber configured to contain a fill material, the wall having a perimeter with a non-circular profile when the chamber is viewed in cross-section. The non-circular profile of the perimeter is configured to allow a volume of the chamber to change without substantially changing a length of the perimeter.
