PR-MEY made its approached to the large structure ship Petrobras P37 with 8 pax and apparently due to the high wind turbulence behind the large structure, the helicopter lost its lift and made a hard landing.
After the hard landing the helicopter turned sideways and since the ship was moving too much the aircraft started sliding towards the edge of the helideck and the captain decided to deploy the floats, in case it hit the water.
No serious injuries.
