Renovations at Alyeska’s Ballast Water Treatment (BWT) facility in Valdez achieved an important milestone on January 30 with the startup of the vapor recovery system for tanks 93 and 94—known as the 90s tanks. Prior to the renovations, the BWT system released volatile organic compounds (VOC) that could have been a safety risk in certain situations. This new Vapor Control System dramatically reduces the risk of fire or explosion and will cut the plant emissions to nearly zero in 2008.

It has been over a year since Alyeska started moving oil at Pump Station 9 with the new equipment installed as part of Strategic Reconfiguration (SR). The SR project involves installing electrically driven crude oil pumps at four critical pump stations (1, 3, 4 and 9) combined with increased automation and upgraded control systems. PS 9 was the first station to receive new equipment.

Valdez project offers environmental, safety benefits

There are times when the job becomes more than a job— when it is not simply a matter of good engineering or regulatory compliance or cost savings. Sometimes, a job is the right thing to do. That is absolutely the case with the Ballast Water Treatment (BWT) renovations at the Valdez Marine Terminal.

Due to lower ballast water flow and the need for health, safety and operability improvements, the existing Ballast Water Treatment (BWT) system at the Valdez Marine Terminal will undergo renovation. The current structure is outdated and oversized for forecasted needs. The BWT system has two purposes: to recover oil from the ballast and to treat the ballast water for return to the sea.
