More Carnival cruises will be departing from Charleston in 2016.

The cruise line announced Monday that beginning next year, the cruise ship Carnival Sunshine will depart from Charleston on four trips.

The Carnival Fantasy is already based in Charleston and routinely sails from the city.

South Carolina Ports Authority Chairman and CEO Jim Newsome says with the new cruises, there will be about 100 departures from Charleston each year.

The authority board learned Monday that container volume during the fiscal year that began last July is up about 15 percent.

The board also approved an engineering contract for design changes on two new massive cranes that will be coming to its Mount Pleasant terminal next year.

The larger cranes are needed to handle a new generation of larger container ships.
