Wärtsilä is supplying air/oil lubricated sterntube seals and bearings to Chinese shipyard Shanghai Waigaoqiao Shipbuilding (SWS) for a series of new tankers under construction by SWS for Singapore-based Ocean Tankers. A complete Wärtsilä package of JMT Airguard seals, sterntube bearings, and shaftline bearings, was ordered in October and December 2006 for installation in the first of 12 Aframax tankers. "We have established a very good relationship with Shanghai Waigaoqiao Shipbuilding, which today is the largest commercial shipyard in China. Since 2001 we have supplied seals and bearings to SWS for 32 bulk carriers and 16 crude oil tankers," said Wärtsilä Seals and Bearings regional sales manager Adrian Higginbottom.
