Narrative:

After takeoff in the initial climbout the right engine oil pressure began to increase beyond normal limits passing from green; into yellow; and then red numbers. The crew reduced power on the engine in an effort to reduce oil pressure without result. The oil pressure could not be maintained within limits. The crew contacted ATC to level off at an intermediate altitude to troubleshoot and consult the aircraft checklist. With the oil pressure steady at 70 psi (engine oil pressure limitation is 55 psi for 3 minutes) the crew declared an emergency and conducted a precautionary engine shutdown of the right engine. Requested and was issued a new ATC clearance to [a nearby airport] where we landed on the runway without complication or incident. On postflight no visible signs of damage or anything out of the ordinary were observed.in the process of diversion several unsuccessful attempts were made to contact the chief pilot to inform him of the event; but the flight phone was not picking up ground stations and the call could not be placed. Immediately after parking and engine shutdown the notification call to the assistant chief pilot was made.
