The idea for optimum trim was born years ago, when 2 sister ships were sailing the same route at exactly the same time with the same destination, draft and speed. At that time it was the early days when people started thinking about optimizing fuel consumption, amongst others ways to reduce cost. Whilst working for a large trading house, it turned out optimum trim solutions are expensive, take a long time to develop and required often hardware installations. Not something a Charterer would like to start using. As a result, Rensmarine started to develop a solution which was cost effective, fast to develop and without hardware installation. In 2016 this resulted in Trim-Advisor.
