MacRack technology for Greece
Each hatch cover panel will be operated by an electrically-driven MacRack unit
MacGregor, part of Cargotec, is to supply electric-drive systems for its side-rolling hatch covers for two new series of Greek bulk carriers.
The five 180,000 tonne bulk carriers will feature the company’s side-rolling hatch covers operated by its “economical and environmentally friendly” MacRack technology.
The order includes the design and supply of key components and the fabrication of the hatch covers.
"Technology that drives new standards of efficiency and minimises environmental impact is an essential element of today's market,” said Torbjörn Dahl, senior naval architect for bulk ships, MacGregor.
"The new orders demonstrate shipowners' willingness to invest in this type of technology and they are a testament to the confidence these particular owners have in MacGregor's ability to deliver this type of solution,” he added.
MacRack lifts the hatch cover panel from its closed position and rolls it away to its open, stowed position. The panels are automatically freed from their securing clients as they are lifted, giving an overall operating time of 2.5 minutes for one hatch.
Automatic motor brakes prevent the panels from unintentional rolling at all stages of the opening and closing process.
MacGregor says it expects MacRack to become the standard system for side-rolling hatch covers as more companies look to minimise their environmental impact.
The vessels are currently being built in South Korea by Sungdong Shipbuilding and Marine Engineering for two Greek owners. The first two are destined for Quintana Shipping and the remaining three for Alcyon Shipping.
The first vessel is due to be delivered at the end of 2014.
