Spartan - That sounds right to me. According to DRYS, the per day charter rates for each ship are:
Anderida - $30,000
Aisling - $30,000
Mont Fort - $28,833
Mont Gele - $28,833
When Mont Gele is delivered in January, the total per day charter rate will be $117,666 or roughly $3.5 million/month.
GE stated back in June he was expecting gross revenues for 2018 to be approximately $77 million. That was before adding Heidmar to the mix. Given the strength of the spot markets and growth in worldwide GDP, I would think the number will be higher.
