Carnival, International Paint Strike Deal

International Paint LLC, an Akzo Nobel company, announced a long-term agreement with Miami-based Carnival Cruise Lines to supply the company’s fleet with Intersleek 700 foul release coating system. The agreement comes after Intersleek 700 was successfully used in a pilot program by Carnival beginning in 2001 to test the coating’s extended life performance in preventing organisms from adhering to underwater hulls. The program was expanded over the next five years. The consistent decrease in annual bunker costs over that time period led to the agreement that now includes 10 ships. Roberto Martinoli, Senior Vice President of Technical, Environmental and Safety Operations, performed a thorough evaluation of the pilot program, which initiated several rounds of negotiations. Martinoli, Brian Swensen and Umberto Sampiero spearheaded these negotiations for Carnival, and Robert Hall, George Smyth, Tom Mulligan and Paul Marzocca for International Paint LLC. The goal was to create a proven underwater coating program that maximizes the ship’s fuel efficiency, creating economic value for Carnival. Intersleek 700 is a silicone-based foul release coating system, providing an environmentally friendly solution to combat marine fouling. The coating also is designed to significantly increase underwater hull coating longevity, providing added fuel savings due to exceptionally low surface tension.

DNV has developed SUNdy, a large-scale offshore solar field concept that aims to help countries seeking alternative energy sources. The core feature of the concept is a hexagonal array which floats on the sea surface. A collection of these arrays, totaling 4,200 solar panels, forms a solar island the size of a large football stadium, capable of generating 2 MW of power. Multiple islands connected together make up a solar field of 50 MW or more, producing enough electricity for 30,000 people
