If increased CAPEX leads to reduce fuel costs and maybe other OPEX, an agreement between the owner and charterer needs to be found. For example, production ranging from a few tonnes a day to millions of tonnes a year, storage in atmospheric tanks or in pressurized tanks, storage of less than 30 m3 up to storage of several hundreds of thousands of m3, and transport by sea, rail or road. Figure 12 provides an overview of the complexity.
