MacGREGOR strengthens presence in Vietnam
MacGREGOR hatch covers for expanding Arctic minerals fleet
Four more icebreaking container ships ordered by Russian owner MMC Norilsk Nickel for Arctic service are specified with folding hatch cover sets designed by MacGREGOR to operate in temperatures down to -50oC
Following the successful introduction into service last year of the 14,500 dwt Norilskiy Nickel from Aker Finnyards Helsinki facility, MMC Norilsk Nickel has commissioned another four of the class from Aker Yards, Germany. For the latest newbuildings MacGREGOR will deliver the complete hatch cover sets and install the hydraulic piping and the tweendeck covers in a contract worth around u201a13 million.
Exploiting the double-acting icebreaking principle in conjunction with electric podded propulsion, the fleet is designed to transport nickel exports from Northern Siberia without assistance from icebreakers.
A container capacity of 648 TEU is arranged in three holds (389 TEU) and on deck (259 TEU), the holds served by an outfit of MacGREGOR hydraulically-operated high-stowing folding hatch covers on the weatherdeck and tweendeck.
The 13-panel weatherdeck hatch cover shipset comprises:
The 22-panel Foldtite hatch cover shipset for the tweendecks comprises:
Operation of the hatch covers in very severe Arctic conditions (down to -50oC) dictates special measures in designing the equipment and hydraulic system and in specifying materials, such as the rubber packing.
