Chevron Corporation has announced that the Big Foot tension-leg platform (TLP) will be moved to sheltered waters from its location in the deepwater U.S. Gulf of Mexico following damage to subsea installation tendons.
The tendons were pre-installed in preparation for connection to the Big Foot TLP. Between 29 May and 31 May several tendons lost buoyancy.
The Big Foot TLP was not connected to any subsea wells or tendons at the time of the incident and was not damaged. There are no producing wells at Big Foot at this time. There were no injuries and there has been no release of any fluids to the environment.
Damage to the tendons, which are not connected to subsea wells and are used to attach the TLP to the seafloor, is being assessed. First production will not commence in late 2015 as planned.
