Narrative:

On cruise climb to FL230 first officer noted the #1 oil temperature had increased into the yellow arc. Unsuccessful attempts were made to cool the oil temperature by increasing fuel flow. When it was obvious that the maximum time limitation of 15 mins with oil temperature in yellow arc was to be exceeded, we performed (using our FAA approved checklists) a precautionary engine shutdown of the #1 engine. We diverted to richmond (WX 300 ft overcast 2 mi visibility RVR more than 6000 ft) and landed without incident. An emergency was not declared, however the emergency equipment was asked to standby as a precaution. Because of our heavy fuel load (we were flying bwi-jax) and passenger load of 75 people, it was necessary to perform an overweight landing of 106300 pound weight (maximum landing weight 105000 pounds). Due to our fast landing speed and heavy weight our brakes were cooled with fans by the fire fighters. We were towed to the gate by maintenance. There were no injuries to passenger or crew and to my knowledge no damage to the aircraft.

Title: HIGH OIL TEMP PROMPTS CREW TO SHUT DOWN ENG AND DIVERT FOR LNDG AT NEAREST SUITABLE ARPT.

Narrative: ON CRUISE CLB TO FL230 FO NOTED THE #1 OIL TEMP HAD INCREASED INTO THE YELLOW ARC. UNSUCCESSFUL ATTEMPTS WERE MADE TO COOL THE OIL TEMP BY INCREASING FUEL FLOW. WHEN IT WAS OBVIOUS THAT THE MAX TIME LIMITATION OF 15 MINS WITH OIL TEMP IN YELLOW ARC WAS TO BE EXCEEDED, WE PERFORMED (USING OUR FAA APPROVED CHKLISTS) A PRECAUTIONARY ENG SHUTDOWN OF THE #1 ENG. WE DIVERTED TO RICHMOND (WX 300 FT OVCST 2 MI VISIBILITY RVR MORE THAN 6000 FT) AND LANDED WITHOUT INCIDENT. AN EMER WAS NOT DECLARED, HOWEVER THE EMER EQUIP WAS ASKED TO STANDBY AS A PRECAUTION. BECAUSE OF OUR HVY FUEL LOAD (WE WERE FLYING BWI-JAX) AND PAX LOAD OF 75 PEOPLE, IT WAS NECESSARY TO PERFORM AN OVERWT LNDG OF 106300 LB WT (MAX LNDG WT 105000 LBS). DUE TO OUR FAST LNDG SPD AND HVY WT OUR BRAKES WERE COOLED WITH FANS BY THE FIRE FIGHTERS. WE WERE TOWED TO THE GATE BY MAINT. THERE WERE NO INJURIES TO PAX OR CREW AND TO MY KNOWLEDGE NO DAMAGE TO THE ACFT.
