Are IMO regulations tough enough to keep national governments from imposing stricter measures?

Only partly
No--expect a slew of regional regs!

MAN B&W 14K98ME-C7

APL orders world's most powerful diesels

APL has ordered eight MAN B&W 14K98ME-C7 engines, each generating a massive 84,280 kW or 115,000 BHP at 104 rpm, to power eight 10,000 TEU ships from Korean builders.

When built, the diesel engines will be the most powerful in shipping history.

In placing its order, APL aligns itself with other major containership owners such as Hapag Lloyd, NVA, OOCL, NYK and K-Line who have also selected MAN B&W K98ME-C engines with electronic controls.

The 14-cylinder engine has been specially developed to meet APL's operational and environmental requirements.

Commenting on the engines, Goh Teik Poh, APL's Senior Vice President, Operations & Network, said: "When we made the decision to build a new generation of large container vessels that will combine high-speed performance with the most advanced environmental features, we naturally looked to MAN Diesel. After working with them for many years, we have the utmost confidence in their ability to provide engines of the very highest quality. The 14K98ME-C7 will allow us to fulfil our customers' needs for speed and reliability as well as paying attention to the quality of life of the global community."

Advantages of the MAN B&W ME-C range of engines include:

  • appropriate fuel-injection pressure and rate-shaping at any load
  • operating mode easily changed during operation
  • a simple mechanical system with well-proven, traditional fuel-injection technology familiar to any crew
  • a control system with precise timing that gives good engine balance with equalized thermal-load in and between cylinders
  • comprehensive monitoring and engine diagnostics contribute to longer time between overhauls
  • lower rpm possible for maneuvering
  • good acceleration, astern and crash-stop performance
  • software upgrades available over engine lifetime

MAN B&W ME-C engines are also environment friendly.

Their advanced, electronic user-interface is intuitive and monitors engine performance, allowing precise adjustment of lubricating oil and fuel variables. Electronic control of fuel injection and exhaust valves, which is optimal at all steady and transient loads, leads to lower fuel consumption, lower cylinder-oil consumption and improved emission characteristics with smokeless operation at any load, and low NOx and soot values.

The new engine can optionally be changed over to different low-emission modes where its NOx exhaust emission can be reduced below IMO limits if necessary to meet to local emission regulations.

Smoke values for the most recent generation of MAN B&W engines are so low that exhaust plumes are typically invisible. The Alpha Lubricator also comes as standard, ensuring a very low lube-oil consumption that in turn reduces particulate emissions.

The APL order follows on the heels of that for a gigantic MAN Diesel engine that entered service early last year. Rated at over 100,000 bhp, it was the largest engine ever designed by the company at the time. On that occasion,

Hyundai Heavy Industries in Korea built an MAN B&W 12K98MC engine with 101,640 BHP for one of a series of container ships of over 9,000 TEU capacity.

The new APL order demonstrates how global demand for container vessels has continued into 2007 with the construction of newbuildings remaining at a high level, particularly in Korea.

Hyundai Heavy Industries (HHI) and Daewoo Shipbuilding and Marine Engineering Co., Ltd. (DSME) will each construct four of the new APL ships, with delivery scheduled for 2011.

With this latest order, MAN Diesel's 98-bore program has now reached a total number of 460 engines built or ordered to date, with an aggregate output of 28,699 MW. Of this number, MAN Diesel has received orders for an incredible 87 (5,823 MW) just this year to date.
