MAY 31, 2017 — A wind service operation vessel (WSOV) under construction for France’s Louis Dreyfus Armateurs by Turkish shipbuilder Cemre Marin Endüstri A.Ş, will be equipped with four MAN 8L21/31 variable-speed gensets. The newbuilding will also feature MAN’s EPROX (Energy Saving Electric Propulsion System), significantly reducing its CO2 emissions and fuel consumption.

EPROX is an innovative, fuel-efficient, diesel-electric propulsion system. that combines innovative electrical technology with industry-leading diesel engines. EPROX will enable Louis Dreyfus to operate the WSOV’s engines at optimal efficiency through its energy-saving, diesel-electric propulsion system which has been developed on the back of recent advances in DC distribution technology.

As well as reducing fuel-oil consumption, the EPROX system also helps to reduce transient loads on diesel engines. In DP operation, this improves the propulsion system’s dynamic response significantly.

The MAN engines will be prepared for IMO Tier III and set up such that they can be retrofitted at a later time with MAN’s SCR system. This is to allow for the possibility of IMO TIER III NOx emission limits being introduced in NOx emission-control areas (NECAs) in the North and Baltic Seas before 2021.

“This new order confirms our solid foothold within the segment for small-bore, medium-speed engines powering specialized vessels,” said Lex Nijsen, Head of Four-Stroke Marine at MAN Diesel & Turbo. “I welcome this new reference and feel that it highlights the diversity of our product portfolio.”

The order follows the recent delivery of newbuildings constructed at Turkey’s Çeliktrans Shipyard for Icelandic fishing company, HB Grandi, where MAN Diesel & Turbo provided each of three trawlers with individual 6L27/38 main engines, SCR systems and MAN Alpha CP propeller plants.

The variable-speed gensets for the Louis Dreyfus newbuild will be assembled and tested at MAN Diesel & Turbo’s Aurangabad facility in India.

Salt Ship Design of Norway is providing the full design and engineering package for the new vessel, which is scheduled for delivery in fourth quarter

The new WSOV will be used for operations and maintenance work on German offshore wind farms, Borkum Riffgrund 1 and 2, as well as Gode Wind 1 and 2.

The 83 m × 19.4-m wide vessel will operate for Denmark’s DONG Energy.
