La Mancha Knutsen
Two LNG vessels, the ‘La Mancha Knutsen’ and the ‘Rioja Knutsen’, owned by Knutsen OAS Shipping have been successfully fitted with Wärtsilä LV shaft generator systems with step-up transformers. The commissioning and sea trials went without hitch in 2016. The Wärtsilä systems effectively reduce the auxiliary engines’ running hours by approximately 50 percent, meaning the time between overhauls can be extended from five years to ten. Maintenance costs and lube oil consumption are also notably reduced, and the overall efficiency of the vessels is increased.
