Claim 12:
13. The method according to claim 12, wherein the method comprises a tripping-in routine, the tripping-in routine comprising the steps of:
connecting the second hoisting cable to the working deck using the connector so as to bring the hoisting system in the first configuration;
suspending the tubulars string from the traveling block;
engaging the tubulars string with the slip device on the working deck near a top end of the tubulars string and releasing the tubulars string from the traveling block thus suspending the tubulars string from the slip device;
lowering the working deck and the tubulars string while simultaneously raising the traveling block thereby creating a space for a tubular between the working deck and the traveling block;
placing a tubular in the firing line between the working deck and the traveling block by means of the tubulars handling device;
connecting, by means of the roughneck device, the tubular with the tubulars string while the working deck is being lowered by the second hoisting device;
lowering the traveling block and connecting the traveling block to a top end of the tubulars string;
releasing the tubulars string from the slip device thereby suspending the tubulars string from the traveling block; and
lowering the traveling block and the tubulars string while simultaneously raising the working deck.
