Heli Student
One of our semi submersible offshore facilities (soon to be installed) will have radar but it is weather radar combined with doppler to show approaching storms which can be very bad in the tropics.
Helicopter crews will be able to interrogate it before they depart for offshore, but it is not designed to "paint" a helicopter neither is there anyone qualified to provide any kind of air traffic advice. Pilots are responsible for their own obstacle clearance when in the vicinity of the field.
