Tienpont was removed from the team last weekend for what was only described by AkzoNobel officials as a breach of contract. The breach was apparently related to Tienpont's management company Steam, which had been contracted to manage all facets of AkzoNobel's entry.
His termination saw Jackson, a veteran of six Volvo campaigns, elevated to skipper a week out from the start of the race.
"This has obviously been an incredibly difficult time for everyone involved since we arrived here in Alicante just 10 days ago. I have now reached an agreement with AkzoNobel and all parties now want to put this behind us and focus on our campaign for the Volvo Ocean Race 2017-18," Tienpont said in a statement.
"I would like to thank Brad Jackson for stepping up at such a challenging time to keep team AkzoNobel moving forward with our preparations for the race," he added.
