Signal International announced
it has been awarded a contract to upgrade the Atwood Oceanics Richmond submersible drilling unit. Upon completion of drilling the current well, the Richmond is anticipated to arrive at the Signal Mississippi Dry Dock yard late September for a life enhancement upgrade.
The Atwood Oceanics Richmond was originally built in 1982 and has seen previous upgrades in 1986 and 2000. As a column stabilized submersible drilling unit, the Richmond is towed to drilling location, then ballasted to land its pontoons
on the seabed. The maximum water depth limitation for the Richmond is 70 ft.
