The latest 13F filling for Temasek Holdings has showed a few new investments into the oil & gas sector. The new stakes include Cameron International Corp, McDermott International‎,  Halliburton and most interestingly Transocean‎, the company that was involved with the doomed Deepwater Horizon rig. Temasek must have picked these shares up right before or right after the explosion since the form covers between April 1 to June 30 of this year.
