MacGregor mooring systems for Mermaid’s tender rigs
MacGregor, part of Cargotec, has won new contracts that will see electrically-driven versions of its mooring systems fitted to two new tender assist drilling rigs for Thailand-based Mermaid Maritime Public Company Limited.
The Self-Erected Drilling Tender (Hull No. CMHI (JS)-151-1 and Hull No. CMHI (JS)-151-2) are under construction at China Merchants Heavy Industry (Jiangsu) Co Ltd with delivery planned for 2016.
The order was booked into third quarter 2014 order intake.
MacGregor will provide each rig with an electrically-driven eight-point mooring system with a 95-tonne line pull, a 460-tonne brake holding capacity and a 1,400m x 64mm diameter wire drum capacity. MacGregor equipment deliveries are scheduled for June 2015.
“The electric winches have variable frequency drives, which consume around 20 to 30 per cent less energy when compared to hydraulically-driven winches,” notes Francis Wong, Vice President, Segment Sales, MacGregor Offshore. “This advantage will significantly reduce the carbon footprint and bring down the initial installation and operation cost.”
“MacGregor can offer comprehensive equipment packages for all types of specialist offshore units,” he adds. “Our portfolio for mobile drilling units has been strengthened with the addition of the Pusnes products.”
