MAN Energy Solutions will supply the engines for a new heavy-lift crane installation-vessel for Oslo-based OHT, a heavy-transport-and-installation contractor.
MAN’s scope of supply covers four 12V32/44CR GenSets with a total output of 28 800 kW. The four-stroke engine has a bore and stroke of 320 X 440 mm.
The new Alfa Lift vessel will be built at the shipyard of China Merchants Heavy Industry in Haimen/Nantong with delivery due in the fourth quarter 2020. The order is for a single vessel, with options for three more.
“We are very pleased to have won this order,” said Lex Nijsen, vice president, head of Four-Stroke Marine at MAN Energy Solutions. “The MAN 32/44CR engine’s multiple references – as well as its excellent references for similar projects within this very segment – were a decisive factor in its selection.”
MAN Energy Solutions describes the MAN 32/44CR engine as future-oriented technology whose common-rail technology delivers significant fuel savings and low operating costs. Nijsen added that the engine meets the customer’s requirements for modern and reliable technology that would continue to deliver high outputs even at high ambient temperatures, a dynamic load response, and minimal exhaust emissions.
The Alfa Lift is a heavy installation crane vessel design with semi-submersible heavy transportation capabilities. The vessel is designed to install all types of bottom fixed offshore wind foundations and will also transport and install topsides and subsea modules, in addition to other heavy cargoes within oil and gas. Featuring a free deck length of 148 m, and a free deck area of 8,100 m² (main) + 2,470 m² (foredeck), the vessel has accommodation for 100 people.
OHT was founded in 2006 and has experience in complex projects serving customers from a wide range of industries, including oil & gas, offshore wind and marine infrastructure.
