pact new L21/31. Initially slanted at marine genset drive applications, the type has made an auspicious commer- cial start through its nomination for the auxiliary installations in the exception- ally high capacity new breed of RoRo trailership contracted by DFDS for its

North Sea services.

In the meantime, Hyundai is readying the first examples of its home-grown

H21/32 medium-speed series for deliv- ery to China as the auxiliary units in two 37,000-dwt ballast barges under con- struction at Shanhaiguan Shipyard.

Each newbuild will be fitted with two six-cylinder models of the four-stroke design rated at 1,200-kW. The in-line

H21/32 covers the 800-1,800 kW range, achieving 160-kW/cyl at a running speed of 720-rpm and 200-kW/cyl at 900-rpm.

While propulsion and gas engine ver- sions are envisioned longer-term, the

Hyundai design is targeted at marine genset and stationary power applica- tions at the outset. Early market recep- tivity to the 210 mm-bore Himsen type was such that sales had reached about 30 sets by July, with the likelihood of steep growth in production on the back of HHI's considerable demand for auxil- iary engines deriving from its shipbuild- ing activities at Ulsan. Of course, shipowners opting for Himsen engines

Litton Avondale Industries, a subsidiary of Northrop Grumman, delivered Polar

Endeavour on April 30, 2001. The vessel is the first of five Millennium-Class dou- ble-hull crude carriers built for Polar

Tankers of Long Beach, Calif. It and its sister vessels will feature dual, separat- ed engine compartments, in order to maintain power in the event of flooding or fire. will be anxious to ensure that they have recourse to the requisite after-sales net- work.

The Himsen banner has also been raised over Hyundai's version of the more powerful medium-speed engine recently developed in collaboration with the Bergen arm of Rolls-Royce Marine.

Bearing the H25/33 designation, as the

Korean equivalent to the Bergen

C25:33, the series will initially be avail- able in 5,6,8, and 9-cylinder versions at 720-750 and 900-rpm crankshaft speeds, spanning unit powers from 1,160 to 2,610-kW. Like the H21/32, the

H25/33 has immediate relevance for

HHI as a genset drive. A six-cylinder

H25/33 is under test at Ulsan, and there is every prospect that the 250 mm-bore type will soon join the H21/32 in expanding the indigenous component of engine production.

Application versatility was a key goal in the Norwegian-Korean technical
