Ocean has completed its line-up for this weekend's non-championship GP2 races at Yas Marina by signing sportscar racer Nicolas Marroc to partner Antonio Felix da Costa.
Frenchman Marroc, 24, has competed in a variety of sportscar series this year, becoming a class winner in the Formula Le Mans category of the Le Mans Series on his way to fifth in the championship, and winning twice in the International GT Open in a JMB Ferrari.
Despite admitting that his future lies away from single-seaters, Marroc believes this weekend's event will be beneficial to him in the long-term.
"It's a dream come true," said Marroc, who tested for Ocean at Yas Marina last year.
"Rejoining Ocean is an immense pleasure, all the more so since this time it will be to take part in two GP2 races. I will do everything to be up to the confidence Ocean's put in me.
"This will be a very important weekend for my career and whatever happens I am sure I will learn a lot of things that will help me meet the challenges awaiting me in the Le Mans Series."
