Teams of workers, aided by ships and aircraft, expected to complete on Monday the sea cleanup of 164,000 liters of oil that leaked off South Korea's southern coast, the coast guard said, after a pipeline run by GS Caltex Corp cracked at the weekend.

A cleanup of shore areas will take up to two weeks.

The crack and subsequent leak occurred on Friday at a quay off Yeosu, more than 300 km (185 miles) south of Seoul, while the 318,445 deadweight ton crude carrier Wu Yi San was preparing to berth and offload crude.
