New York-listed Diana told investors the three contracts will add revenue of at least $12.73m.
The deals came as rates in both sub-sectors began the week with upward movements after slipping back over the few sessions.
Diana says the 179,100-dwt PS Palios (built 2013) has been taken by RWE for a further 22 and 25 months.
The rate of $13,000 daily compares with the $9,800 per day available in the spot market at the end of last week.
