The first Tier-II compliant MAN B&W engine has finished production at HHI-EMD (Hyundai Heavy Industries Engine & Machinery Division) in Korea and is ready for delivery.
The low-speed, two-stroke MAN B&W 6S50ME-C7 type engine will power a shuttle tanker (hull number 1749), currently under construction by Samsung Heavy Industries, and ordered by Teekay. Ship delivery is planned for July this year.
Under the terms of the contract, the 6S50ME-C7 engine is intended for Teekay's Amundsen-class of ships. Teekay actively sought for production to meet DNV (Det Norske Veritas) Clean-Design Notation requirements that comply with the strict, IMO Tier-Il emission limits, setting in train the production of the first Tier-II compliant MAN Diesel engine.
Tier II shows the great advantage of MAN Diesel's ME-engines.
"Traditionally, lowering nitrogen oxide levels requires an increased fuel consumption but with ME-engines, this can be minimised due to their rate-shaping injection profile
capability,", Søren H. Jensen, Vice President and Head of Research & Development, Marine Low- Speed, MAN Diesel, said.
"This provides for unlimited possibilities to adjust the injection profile compared with the on-off method favoured by common-rail engines. The market should also know that despite being currently occupied with Tier-II compliancy, we are already looking beyond it to the next step, that is, Tier III, and full compliancy with its stringent emission levels by 2016."
