We consider the incompressible Navier-Stokes equations in a bounded domain with $\mathcal{C}^{1,1}$ boundary, completed with slip boundary condition. Apart from studying the general semigroup theory related to the Stokes operator with Navier boundary condition where the slip coefficient $α$ is a non-smooth scalar function, our main goal is to obtain estimate on the solutions, independent of $α$. We show that for $α$ large, the weak and strong solutions of both the linear and non-linear system are bounded uniformly with respect to $α$. This justifies mathematically that the solution of the Navier-Stokes problem with slip condition converges in the energy space to the solution of the Navier-Stokes with no-slip boundary condition as $α\to \infty$.
