Chevron Corporation orders G-type units with integrated exhaust gas recirculation G-type engines with integrated EGR system offer both high efficiency and low NOX emissions. MAN Diesel & Turbo has received an order from Chevron Corporation, the American multinational energy company, for two lightering newbuildings with each vessel to be powered by an MAN B&W 6G70ME-C9.2 prime mover. The newbuildings will each use an MAN Diesel & Turbo EGR (Exhaust Gas Recirculation) system to help their ME-C prime movers meet Tier III emission standards well in advance of requirements coming into effect. The engines will also retain the ability to switch to Tier II operation when outside the ECA (Environmental Control Area). MAN Diesel & Turbo states that the engine for the first vessel has a delivery date in December 2012, with the second due in early 2014 and the vessels due for delivery in 2014. Chevron has also ordered 1 × MAN 8L27/38 + 2 × MAN 7L21/31 gensets for each v... [More]

MAN Diesel & Turbo 6S46MC-C8 engine fulfils IMO Tier3 with SCR.

A testing programme with factory personnel commenced in January 20111 on a 6S46MC-C8 engine built by licensee Hitachi Zosen: the purpose was to commission the engine control system and optimize the integration of the SCR equipment. The engine develops about 7 MW at a speed of up to 129 rpm. The SCR removes NOx from the exhaust using urea as an activator. Further reduction of emissions in the exhaust system are achieved using Exhaust Gas Recirculation (EGR) techniques. On completion of the tests, MAN Diesel & Turbo claimed a world first as the engine met all emission requirements laid down in the IMO Tier 3 regulations effective 2016. [More]

Motoryacht Ark Angel

Sauter Carbon Offset Design recently introduced the superyacht Ark Angel with a design claiming to be faster and far greener than any megayacht in her class. The 78 m hull and decks are of Carbon/Kevlar composite construction, beam is 10 m and draft 2.4 m (at 50 per cent load): the superstructure is aluminum giving a displacement of 450 tons. The total propulsive power of the ship is 4,000 kW, split between three electric pods with counter rotating propellers (CRP).
The main engines ares four 400 kW diesel electric gensets powered by Daimler Bluetec Turbo Compound DD16 engines. BlueTec emission technology is a fully automatic system used for automotive applications to comply with the more stringent (than marine) emission regulations. A generous battery capacity of 3MWh permits propulsion solely on battery electric drive, electric power generation is also by solar cells Motion Damping Regeneration.

DNV Quantum 9000 Concept Container Ship

Yesterday in London, DNV announce the new Quantum 9000 concept container ship with twin island layout. Considerably larger than the Quantum of 6,200 TEU announced last year, the new 9000 model has a design speed of 22 kn and target capacity of 9,000 TEU yet will be able to use the post 2014 Panama Canal opening up routes from East Asia to the west and east coast ports in USA. The new ship is powered by a single slow speed dual fuel MAN B&W 9S80ME-C9.2-GI rated at 40 MW at 78 rpm. An Exhaust Gas Recirculation (EGR) system on the engine reduces NOx emissions substantially and the addition of a Waste Heat Recovery (WHR) system improves overall efficiency. The payback time for the increased cost of this ship with all its features is estimated to be five to eight years depending on the cost of fuel. [More]
