Preface
This thesis present a design and analysis study of the pressure vessel for a remotely operated
vehicle (ROV), produced by injection molding. The thesis is a part of my Degree in Master of
Science with specialization in Marine Technology at the Norwegian University of Science and
Technology (NTNU). The thesis has been written entirely during the spring semester in 2016,
