Sonsub - News - December 2, 2004
Sonsub has successfully utilized
and seal tested the first ROV installed deepwater
elbow clamp in the Gulf of Mexico. Working off
the HOS Innovator with the Innovator 09 ROV, the
clamp was used to repair two holes on a 4"
service line on a pipeline sled in 4200fsw.
Tasks for Sonsub included the design, manufacture,
assembly and testing of the required equipment
used to facilitate the remote installation of
the Team Industrial Services designed clamp; SIT
testing of the clamp; and installation procedures
which enabled the ROV to float the 980lb clamp
onto the elbow, install and torque the bolts and
pressure test the clamp.
Additionally, Sonsub designed and manufactured
an epoxy injection system which was successfully
employed to inject the Team Industrial Services
developed epoxy components into the clamp as a
backup sealant on the repair. This was another
first in the Gulf of Mexico.
