Measurement of Single W production and Triple Gauge Couplings in e+e-          
Collisions at centre-of-mass Energies up to 202 GeV                            
  
     Measurements of single W production in e+e- collisions                    
     have been performed using data collected with the OPAL                    
     detector at LEP, at centre-of-mass energies up to 202 GeV.                
     Measurements of the triple gauge coupling parameters                      
     of the gWW vertex are obtained from the total event rate                  
     and from the kinematic distributions of the selected events.
