How to achieve energy efficiency excellence

In a competitive market, energy efficiency is high on the agenda of every shipping company. And as fuel prices will most likely rise again, shipping companies cannot afford to leave this stone unturned. On paper, they already do so, since every vessel of more than 400 GT has to have a Ship Energy Efficiency Management Plan (SEEMP) on board. Yet, only few achieve the savings they could reap in practice.
