STBD TRANSFORMER TRENDS.pdf

This document contains operational monitoring data and system status reports for a dredge vessel, specifically displaying STBD (starboard) transformer temperature trends and AC chiller system status information.

The first three pages present temperature monitoring graphs for the OSDP STBD transformer spanning from June to late June 2021. Each graph displays multi-line temperature data with timestamps and temperature fluctuations measured in Fahrenheit, with readings ranging from ambient to approximately 300°F. The data includes historian records with tagged measurements for OSDP-2 trans secondary wind A, B, and C transformer parameters, along with minimum and maximum values set at 300°F, and server information. The fourth page displays an AC chiller STBD system status dashboard dated 07/04/2021, showing dredge pump operational parameters including overside and inboard dredge pump port and STBD configurations. The status indicators track alarm conditions, cooling water faults and warnings, pump operation metrics (RPM actual drive speed ranging from 288-289, drive current at 332-355A, drive volts at 2166-2190V), transformer temperature status, line supply presence, and power conditions. The transformer secondary winding temperatures are documented for three phases across both secondary and tertiary sections, with Phase A readings between 146-194°F, Phase B between 157-204°F, and Phase C between 160-192°F.
