Expanding UK owner Tufton Oceanic Assets is aiming to raise $100m through a share sale - with more to come over the next year.
The company said it will issue 100m C Shares at $1 each by 25 September.
A placing programme could also see it sell another 200m ordinary or C shares over the next 12 months.
It said it believes that "capital availability for shipping continues to be constrained, and the supply side recovery is continuing and driven by an order book near a 20-year low while second hand prices in many shipping segments continue to be significantly below depreciated replacement cost."
