Tanev gave the Kraken a 1-0 lead at 14:32 of the second period. It was the first time Seattle scored the first goal in a game.
After skating around Oliver Bjorkstrand in the right face-off circle, Tanev cut toward the net, faked a shot with his forehand to freeze Merzlikins, and lifted a backhand inside the near post.
Tanev scored two goals in the Kraken's first victory, 4-3 at the Nashville Predators on Thursday, but said his role is being a complete player.
"It's doing anything the team needs, whether it's blocking a shot, making a big hit or just playing simple," he said. "It's moments on the ice and understanding where you need to be that I bring every night."
Grubauer made the save against Laine on a breakaway at 12:06 of the second period and against Werenski on the rebound at 12:08, but for the second game in a row the Kraken struggled in the third period; they were outshot 13-1 by the Predators in the third Thursday.
"We've got to find an identity in the third period," Seattle forward Ryan Donato said. "That will come with time. We've got a lot of new guys on this team. We know we can't sit on our heels and take off the pressure."
The Blue Jackets finally broke through in the third when Robinson scored on their 21st shot.
"It's really nice feeling," Merzlikins said. "We still had our mistakes. We have to keep working."
After an 8-2 victory against the Arizona Coyotes in its season opener Thursday, Columbus coach Brad Larsen said he saw improvement in the second game.
"I thought we were a lot more plugged into this game," the first-year coach said. "It was a grind, but structurally we were better in a couple of areas we had addressed as a group."
NOTES: Alex Wennberg became the first Kraken player to face a former team. The forward played 415 games for the Blue Jackets from 2014-2020. He faced Columbus last season with the Florida Panthers. … The Kraken were not called for a penalty. The Blue Jackets were assessed one, rookie forward Cole Sillinger for cross-checking Joonas Donskoi 17 seconds into the second period.
