Description

1.2.NLV Pharos currently uses a SPEMOS (SpEed MOnitoring System), which is a proprietary relay system developed for Wartsila (Finland) engines to monitor engine speed, and perform several configurable relay functions. In August 2023, Wartsila issued Technical Bulletin WS23T546, "Lifecycle status announcement, DESPEMES and SPEMOS speed monitoring system" (Annex A), which advised that the SPEMOS system is entering obsolescence.

Annex C: Technical Bulletin WS23T644, "Lifecycle status announcement, Woodward 723 and 723 Plus speed control products".
