**4. Case Study**

#### *4.1. Target Ship Descriptions*

LH2 carriers with five different sizes are considered for the subsequent case studies. The data of LNG carriers from the Clarksons database is used to assume the cargo capacity, rated output of motors for propulsion, and deadweight of LH2 carriers [38]. The deadweight of an LH2 carrier is assumed to be sum of the LH2 cargo weight and the deadweight of an LNG carrier without cargo and with the same capacity. The rated output of the motor (MPP) is calculated to have the same propulsion power of an LNG carrier with the same capacity. Table 5 shows the specifications of the LH2 carriers based on these assumptions.
