Introduction

Customer

Chevron – Oil Tanker (“Vega Voyager”)

Market

Oil & Gas

Situation

Because the oil tanker’s structure flexes while at sea, misalignment between the pump and its motor caused accelerated wear on the bearings and mechanical seals. This also caused vibration-related problems on the pump end.

The Solution

  • MagnaDrive installed a VTX-07 coupling on the oil transfer pump while the Vega Voyager was in port for routine service
  • Chevron noted at this time that they were replacing the system’s mechanical seals at least twice a year.

The Results

  • After the removal of the disc coupling and installation of the VTX-07, Chevron’s vibration expert measured a 75% decrease in system vibration.
  • The seals and bearings no longer needed replacement multiple times per year; Chevron’s annual maintenance costs for the system were reduced from $16,946 with the disc couplings to only $1,523 with the VTX-07 from MagnaDrive.
