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.
