NYK Line could have two ammonia-fuelled handymaxes ready before 2028 to operate one of the first long-haul green shipping corridors, an executive tells TradeWinds.

Executives at the Japanese shipping giant said the timetable remains ambitious and key details on cost still need to be thrashed out before the venture becomes a reality.
