Heikki Kovalainen admits he was to blame for his crash in Practice One and has thanked his mechanics for getting him out onto track later in the day.
Kovalainen suffered a huge shunt when he lost control of his CT01, slamming sidewards into the wall at Turn 9.
The impact caused significant damage to his car and the session to be red-flagged as there was debris strewn all over the track.
But despite the massive repair job awaiting his mechanics, Kovalainen was back on track before the midway point of Practice Two and went on to set the 16th best time.
"First I want to say thank you to the team for doing a great job and getting the car fixed and ready for most of FP2," said Kovalainen.
"I made a mistake on the exit of Turn 9 and hit the wall, obviously doing some pretty substantial damage to the car but, thankfully, not to the chassis.
"As soon as we got it back to the garage the guys started work on rebuilding it so to get that job done and giving me FP2 track time was a very good achievement.
"Before the FP1 off the car had felt good pretty much from the first lap. In FP2 I had the same sort of positive feel from the balance and I think we look ok here - not quite as close as we were in Monaco but certainly close enough to have a good race on Sunday."
