2011: Anderson enhances coastline oil well decommissioning by introducing the Mobile-Island Model (MIM). The MIM would first be deployed along a diminished shoreline in southwest Louisiana. After successful completion of it’s inaugural project, the MIM would become a finalist for the contracting clients yearly innovation award.
About the Mobile-Island Model: With the diminishing Gulf Coast Shoreline, many oil wells which were once on dry land, are now situated in a shallow wetland. Common practices for re-plugging such wells included building a caisson around the wellhead and pumping out the entrapped water. This process results in a muddy, slippery working area nested below sea level; which also creates a dangerous confined space. Within these treacherous circumstances, workers then must perform a perilous task of dealing with compressed wellhead pressures while surrounded by water and threatening wildlife.
Anderson and its sub-contractor team pioneered a new approach that proved to be successful and much safer. Rather than removing the water, the Anderson team turned it into their ally. Engineering a customized river barge, Anderson created three “mobile islands” which allowed access to the wellhead. These mobile islands allowed for the easy transfer of large equipment and workers from a local dock to the shallow marshland. Work could then be completed above the well with no need for water extraction. This innovation was selected as a finalist for the client’s yearly international innovation awards and has been repeated on additional Anderson lead projects.
