Claim 13:
14. The method according to claim 12, wherein the method comprises a tripping-out routine, the tripping-out 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;
raising the traveling block and the tubulars string while lowering the working deck;
engaging the slip device of the working deck to the tubulars string below an upper tubular, while the working deck, traveling block and tubulars string are being raised;
separating the upper tubular from the tubulars string using the roughneck device;
removing the upper tubular from the firing line using the tubulars handling device;
lowering the traveling block while simultaneously raising the working deck and tubulars string;
connecting the tubulars string to the traveling block and disengaging the slip device from the tubulars string thus suspending the tubulars string from the traveling block; and
raising the traveling block and the tubular while simultaneously lowering the working deck.
