Various technologies need to be combined in a holistic approach to powering vessels and tackling fuel-emissions issues, says Riku-Pekka Hagg, vice president of ship design at Wartsila Marine Solutions.
Also, the cost of manufacturing is being considered more when designing vessels after the rush towards so-called eco-ships.
Wartsila, the Finnish power and marine technology provider, has ploughed much of its investment into LNG as a fuel, while at the same time being one of the leading suppliers of scrubbers.
