In the marine market, tight deadlines and budget constraints are common obstacles to overcome. Even finding a qualified welder for a marine application is a challenge, so being able to join pipe without flame can make all the difference in the marine world. Reducing time spent on repairs and labor expenses means you can focus on doing your job and keeping your crew safe. However, when dealing with a work environment that involves floating on a volatile sea, it can be difficult to ensure safety and precision while operating ocean-based support vessels, drill ships and oil platforms.
Designing efficient vessels is the heart of what naval architects do. Efficiency in this case is defined as the ratio of useful travelled distance of goods or cargo; divided by the total energy put into the transportation propulsion means. In other words, a more efficient vessel design will require less fuel (cost) to move a given cargo a certain distance. This paper will explain why efficiency is important and will explore some aspects of small coastal vessel design that can improve vessel efficiency. We will also investigate several of the techniques that are used to analyze a vessel’s efficiency utilizing Articulated Tug-Barge (ATB) units as case studies.
