PASCAGOULA, Mississippi -- Signal International has delivered the semisubmersible Frontier Driller after completing a major upgrade and modernization.

The work included a new derrick (single lift) and new BOP handling structure; addition of winch decks (four corners), new riser decks and new ROV deck; raising a mud pit roof; converting chain lockers to bulk mud tanks; and adding a new cement deck. A new helicopter deck and aft lifeboat deck were also set and secured, the company reports.

All pipe systems were renewed, modified, or completely replaced and tested, along with the rig’s HVAC systems. The entire electrical system on the Frontier Driller was completely re-powered, including all four mains, all new SCR, and MCC. All columns, under deck, exterior, and interior spaces were cleaned and painted.

The final phase of the project consisted of fabricating and installing 1,000 tons (907 metric tons) of steel, adding two pontoon sponsons and four columns to the rig. Signal fabricated one new column, while subcontracting and managing the fabrication of the remaining components. The three fabricated columns were each received in three unfinished sections. Each column was assembled and outfitted with ladders, man-ways, and vent piping, then blasted and painted internally and externally.
