Seals for the Ocean Environment

Abstract

Three basic types of seals used to exclude the ocean environment are described: linear seals, dynamic seals, and general penetrant sealants. The section on linear seals culminates with a list of important design considerations for ideal flange seals. The section on dynamic seals reviews the theoretical aspects of designing rotary and reciprocal seals. An example design analysis, including sample calculations for a rotary O-ring spindle seal, is presented with emphasis on how environmental parameters affect dimensional characteristics. The section on general penetrant sealants introduces various types of rigid and flexible epoxy and elastomeric sealants used around electrical cables, hoses, tubes, etc., that penetrate walls of submerged structures.
