The percentage of “alternative” propulsion container ships in the orderbook has risen above 40% for the first time.

The increase follows a spate of methanol dual-fuel orders that are poised to overtake LNG in terms of capacity ordered for the first time, according to Alphaliner.

LNG dual-fuel boxships account for nearly 30% of the orderbook, with 198 ships of 2.31m teu.

That is LNG’s highest proportion to date, and is up from a 25% share of the orderbook 12 months ago, the analyst notes.
