Great Lakes Dredge & Dock Corp has taken delivery of two shallow-draught workboats from Conrad Shipyard in Morgan City, Louisiana to enhance its pipe handling and anchor operations
Cape Hatteras and Cape Canaveral were built to Damen’s Multi Cat 3013 design with additional deck machinery to enable various marine operations.
These 30-m vessels are each powered by three Caterpillar C32 TTA engines, rated to US EPA Tier 3 emissions standards providing enough power for a top speed of 10 knots and maximum bollard pull of 32 tonnes.
“This is a milestone for our company and the US dredging industry,” says Great Lakes senior vice president of project services and fleet engineering Chris Gunsten.
“The Multi Cat brings step change safety improvements to our dredge pipeline operations, which was a prime driver for the investment. Pipe handling and connection work can now take place securely on deck, which will greatly reduce the risk of man overboard.”
These vessels are equipped with two large winches and two deck cranes to support dredging operations and a wide range of tasks including handling submerged and floating pipelines, anchor handling and logistics supply. They will minimise the need for assorted floating support equipment, such as derrick barges, towboats and anchor barges.
“These vessels will also enhance and improve our pipe and anchor operations,” says Mr Gunsten. “Further, the two cranes and multiple winch and wire tugger arrangements will significantly reduce manual work and the risk of soft tissues injuries,” he adds. “These vessels support our strong safety culture and give us the ability to dredge with the enhanced operating efficiencies needed to maintain our shorelines and waterways.”
