Diligent Holdings has extended an impressive run of dry bulk acquisitions over the past three years with the purchase of a supramax bulker.

The Athens-based company purchased the 56,100-dwt Future Lily (built 2012) for about $15.2m, according to London brokers.

Diligent managers declined to comment, citing standard company policy not to discuss commercial matters.

The Future Lily would be the youngest ship in the Diligent fleet.

A deal would also push the company's total acquisition volume since early 2016 to six handysizes and as many supramaxes, for an estimated amount of about $130m.

That includes the unconfirmed purchase of the 57,000-dwt Korean Lily (built 2008), again from Doun Kisen, for about $14.1m, reported by TradeWinds last month.

Diligent managed a single handysize vessel when it was established back in 2011.

It added six more handysizes in a first expansion phase between February 2016 and the autumn of 2017, before it switched to buying supramaxes.

Diligent favours Japanese-built tonnage. The vessels it has acquired were built between 2007 and 2012 by yards in Japan or at Japanese-controlled Tsuneishi Heavy Industries (Cebu) in the Philippines.

All but two of these ships had been previously owned by Japanese companies.
