When you try to NIntegrate your expression, the error messages include: "suspect one of the following: singularity, value of the integration is 0, highly oscillatory integrand, or WorkingPrecision too small". Your expression does not have a singularity, its integral is manifestly not zero, it is not oscillatory, so it must be a numerical precision problem. ...

Since your integrand does not approach zero but a finite positive number, Limit[Exp[-16.136 (1 - Exp[-0.012*t])], t -> Infinity] (* 9.82255*10^-8 *) the integral over {t, 0, Infinity} does not converge. By the way, the error in the NIntegrate[integrand, {t, 0, 1000}] should be about 10^-7, which seems better than R. In fact, the precision seems ...
