According to Wärtsilä internal checks have revealed irregularities in tests conducted in Trieste, Italy to measure fuel consumption in outboard engines.
The company said that the deviations were on the order of about one percent, and appeared in about two percent of all of the outboard engines it had delivered. It also noted that the discrepancies would have little impact on customers, adding that the products in question had otherwise met sea trial requirements.
Wärtsilä said that a group of workers had clearly violated the company’s guidelines and operating principles, and that it took the matter very seriously.
The company said that it had consequently reviewed all of its test procedures and "taken immediate corrective action". It did not indicate if any action had been taken with respect to the employees implicated in the case.
According to Wärtsilä, there was no indication of deviations in other operations and engines used by power plant customers were not affected.
