What you have described is viewed as an unsafe procedure this side of the N Sea. To have the "approach" handling pilot look up at (M)DH aquire the runway/rig and then land is not good SOP. At a critical point of the flight you have one pilot switching from IF to visual in very poor conditions and nobody on instruments should inadvertent return to IMC take place. In the UK it is SOP for the "approach" handling pilot to call "decide" at (M)DH and the "approach" non handling pilot to call "visual I have control " and land the helicopter. This is particularly important on a rig approach where one pilot is usually unable to see the deck in the final stages of a landing. What you describe is feasible if you cloud break well above (M)DH but not in the usual conditions of a winter approach in the N Sea.
