PASCAGOULA, Mississippi -- The Noble Amos Runner is drilling in the Gulf of Mexico following Signal International's delivery of the upgraded semisubmersible drilling rig seven days early.
The shipyard work, done at Signal's Pascagoula East facility, primarily was to enhance the rig's ability to maintain station during severe weather.
The mooring was upgraded to a NC5 rating and the mooring equipment was enlarged from a nine-point spread to 12-point spread. To enhance stability, 520 tons of column water plane tanks were installed. 270 tons of windlass deck extensions were installed for added mooring winches. Column anchor bolsters were modified to accept larger-capacity anchors. Columns and diagonals were painted and a five year American Bureau of Shipping survey was completed.
