  • Factors Driving Wreck Removal ApproachSUCCESSFUL WRECK AND POLLUTION REMEDIATIONCOSTSCHEDULETECHNICALMinimize Cost? Reduce schedule with innovative recovery approach/technology Increase schedule with proven techniquesMinimize Schedule? Apply innovative recovery approach/technology Increase workforce and equipmentMinimize Technical Risk? R&D innovative recovery approach/ technology before application Increase workforce and equipment

  • JACK-UP MODU - GoMDrifted 5000, capsized, and sank at 113 water depthMost fuel tanks damaged during IKEArrangement & depth allowed traditional recovery techniquesChallenges-Limited floating resources in wake of Ike responseLimited weather window

  • JACK-UP MODU - GoMSystematic inspection via divers & tapsExcavation required to access smaller tanks and barrel stores~36K gallons recovered 2008Additional pockets discovered & removed in 2009 when recovery efforts continued

  • Hot Tap Recovery

  • Hot Tap Recovery

  • Dredger Sri LankaMay 2009 Aground on tetrapod breakwater during monsoonWeather prevented recovery efforts until January 2010POLs observed released from May onward

  • Dredger Sri LankaWreck severely damaged during monsoonSurvey discovered one small hydraulic oil tank intact oil was removed via tapIn-situ Cut Up pieces sized to keep fuel/POL tanks intact

  • Challenges for World Wide Wreck RemovalCreate environment that encourages quick POL recoveryRecovery rates higher and costs lower when POLs recovered from wreck instead of waterLimit responder third-party liability exposureCost Effective Assets & Technologies for:Remote SensingSaturation DivingDeepwater RecoverySurface Platforms capable of operating in adverse weather conditions
