Battery, LNG and shore power were amongst the technologies discussed by major cruise companies, who shared their current research and development initiatives as they work towards zero-emission operations.<\/p>\n
Speaking at Mercator Media\u2019s annual environmental conference, Tor Svensen, vice president of maritime technology at Royal Caribbean Cruises, demonstrated that, while investments are ongoing in battery development for shoreside and sea operations, not all the maritime sector believe it is a feasible application for the whole industry.<\/p>\n
\u201cBatteries are ideal for short-sea shipping but not for anything else,\u201d he said, adding that fuel cells show promise but are a \u201csolution for the future\u201d.<\/p>\n
LNG is also regarded as being part of the sustainable fuels drive, Mr Svensen said. On the subject of tackling NOx and PM, he stated that LNG and SCR can cut these emission to just 1%.<\/p>\n
\u201cAmbitious but realistic targets are what is needed,\u201d he stressed.<\/p>\n
Tom Strang, SVP maritime affairs at Carnival, told delegates that it works closely with ports in order to maintain a constructive dialogue on technology developments that are feasible for both sectors, a strategic move made more important he said, because the \u201creal dilemma in industry is not knowing which direction to go in.\u201d<\/p>\n
In contrast to Royal Caribbean Cruises\u2019 stance on fuel cells, Mr Strang noted that commercially used fuel cells will be used by Carnival from 2021. <\/p>\n
Like Royal Caribbean Cruises, Carnival is confident in the benefits of LNG, despite the eco challenges it presents. \u201cMethane slip is an issue from LNG, but we think we can solve it, said Mr Strang.<\/p>\n
This contrasts with the view of Viking Cruises, whose founder and chairman, Torstein Hagen, said during a keynote address, \u201cWe do not believe LNG is a solution for the future, not even a temporary one.\u201d<\/p>\n
Offering a perspective on the complexities of ascertaining the right port investments to make while accommodating the requirements of cruise and commercial shipping companies, Nils Kemme, associate partner, HPC Hamburg Port Consulting GmbH, spoke about creating a logical and methodical analysis process.<\/p>\n
His session on how ports can make fully informed decisions about reducing emissions identified four steps. These included terminal inspection to understand the port\u2019s energy consumption; shortlisting to identify promising improvement measures; simulation analysis to quantify energy saving and impact on operations and life cycle assessment to assess and compare emissions over life cycle of an asset.<\/p>\n
He warned that while a port \u201ccan shortlist 20 or so measures it doesn\u2019t mean they are good for every port\u201d.<\/p>\n
\u201cA typical process might be to identify five or 10 measures that can be implemented,\u201d he added.<\/p>\n","protected":false},"excerpt":{"rendered":"
