The vessel will be renamed Aliki and is expected to be delivered on or about April 30, Diana said.
The company also said Tuesday it has entered into a time charter contract with Cargill International SA for the Aliki.
The contract, which is expected to begin immediately after the vessel is delivered, is for a 46- to 49-month period at an average rate of $48,500 per day, with a one-year extension at Cargill's option at the same rate.
The contract is expected to generate gross revenue of about $37 million during the first two years and $32 million during the third and fourth years.
If Cargill exercises its option for the fifth year, the charter is expected to generate aggregate gross revenue of about $86 million over the entire period, the company said.
Diana shares rose 58 cents, or 3.2 percent, to $18.50 in afternoon trading on the New York Stock Exchange.
