Narrative:
On feb/thu/97 at XX16 I landed a bell 206 biii helicopter on an oil and gas platform in the gulf of mexico. Already on the platform was a BH206L helicopter, shut down with the blades tied down. I landed my helicopter next to the other one and shut it down and tied down the blades. I went down stairs to the quarters. While I was downstairs, the other pilot came upstairs and untied his rotor blade, but did not swing the blade out. He then went back downstairs. I then went upstairs and untied my blade and swung it out perpendicular to the helicopter. I did not know the other pilot untied his blades. He did not tell me this. I started my helicopter and was bringing it up to 100% N2 when the blade from the other helicopter swung around and made contact with my operating rotor disc. I then shut down my helicopter. 1 blade on each helicopter received minimal damage.
