Solbakken, chief executive of the Oslo-listed owner, bought 100,000 shares at NOK 32.64 ($5.29) each.
The purchase, which came at a 20% discount given a three-year lock in, takes his Ocean Yield stake to 700,155 shares.
Last week Ocean Yield raised NOK 400m ($65m) from a bond issue and netted a $250m loan.
