MAN Energy Solutions has won an order to supply the engines for a new heavy-lift crane installation-vessel for Oslo-based OHT (Offshore Heavy Transport), the specialist heavy-transport-and-installation contractor. MAN’s scope of supply covers 4 × MAN 12V32/44CR GenSets with a total output of 28,800 kW.

The new vessel will be built at the shipyard of China Merchants Heavy Industry in Haimen/Nantong with delivery due in Q4, 2020. The order is for a single vessel, with options for three more.

Lex Nijsen – Vice President, Head of Four-Stroke Marine at MAN Energy Solutions – said: “We are very pleased to have won this order. 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 design of the 32/44CR engine with its proven robustness moreover contributes to the highest reliability, simple maintenance and long maintenance intervals. Additionally, and for many years now, all medium-speed engines from MAN Energy Solutions have been prepared for Online Service, which offers several benefits to clients like increased availability of engines, rapid and comprehensive support for the operating personnel.
