A fresh wave of up to 30 orders worth nearly $4bn for midsize container ships of between 7,000 teu and 8,000 teu is about to hit the newbuilding market.

Shipbuilding sources said this size of neo-panamax will dominate the boxship newbuilding market despite there already being close to 70 vessels of between 6,000 teu and 7,000 teu — worth $6bn — booked at shipyards in South Korea and China.
