The Irish shipping industry grew strongly last year after posting an estimated turnover of some €1.69 billion, according to new figures.
A report published by the Irish Maritime Development Office (IMDO) said growth was particularly strong in the load-on/load-off and roll-on/roll-off sectors.
A total of €158 billion worth of merchandise goods were transported by the Irish supply chain in 2006.
In the bulk sector.many regional ports had double-digit growth including Dundalk, Greenore, Waterford, Drogheda and Tralee/Fenit, the report said.
IMDO director Glenn Murphy said: "Maritime transport also continues to be the most environmentally sustainable and cost-effective means of moving large volumes of goods," he said.
"The ports and shipping sectors are important facilitators of economic growth and efficiency. I have no doubt that good international transport systems help to increase economic efficiency, support deep and productive markets and allow business and participants to reap the benefits of the global marketplace."
The shipping industry employs 8,300 people directly.
