Career Seaman moved to Alberta shortly after graduating to work in the oil industry with his two brothers, Donald and Daryl Seaman. They first established Seaman Engineering and Drilling Co. Ltd. (shortened to Sedco). It became noted for providing the option of turnkey contracts at a fixed price, rather than bidding a price for every foot drilled. The company also covered a portion of the drilling costs to secure the contract, as well as for services like cementing and casing.

Under his co-ownership, the franchise won their only Stanley Cup in 1989. They reached two other Stanley Cup Final series in 1986 and 2004, losing to the Tampa Bay Lightning in seven games in the latter. one year after his brother Daryl died. He was also conferred the Governor General's medal.
