Holeby has sold the first of its recently upgraded Mk. 2 L23/30H four-stroke generator sets
In connection with MAN Diesel & Turbo’s recent repositioning of Holeby GenSets to within its Copenhagen-based Low Speed business unit, the company earlier announced the uprating of its classic L23/30H workhorse.
Doosan reports having sold the first uprated model to Samjin Shipbuilding Industries (SSI) in Korea for a European operator with delivery due in November 2012, while MAN Diesel & Turbo says that several other of its licensees have already signed technical agreements for the production of a L23/30H Mk. 2 for another European operator.
In a recent interview with DieselFacts, MAN Diesel & Turbo’s technical customer magazine, Mikael C. Jensen, Vice President and Head of Engineering for the Low Speed Business Unit, confirmed the uprating and stated it was the first of many technical adjustments planned for the Holeby four-stroke programme.
MAN Diesel & Turbo states that the L23/30H Mk. 2 has already had a positive response and increased orders for an engine that originally entered the market in the mid-1960s – to date, over 10,000 such engines have been manufactured.
The MAN L23/30H Mk. 2 generating set has undergone some significant design changes and now has:
an increased power yield of just under 10%
; a TCR turbocharger for greater efficiency and more service friendliness
; a simplified, integrated nozzle cooling system that reduces installation costs
, and the introduction of a monocoque design to reduce weight and cost.
