residuals not converging

i have an offshore structure(TLP-tension leg platform). when i am running simulation in star ccm+ i am unable to converge the solution. the inial residual for momentum(x,y,z) are high. after reducing the under-relaxation factors also, all in vein.

It seems the problem is because of low mesh quality.
But before that go to Continua/physics, click on the flow and turbulence model. Change them from second order to first order. If it started converging, let converge until getting uniform horizontal lines, then again change to second order.
Hope it will work
