Shell raising North Sea drilling platforms by one meter
Shell Norway PR — public relations, Press briefing on offshore engineering
“Our offshore installations are engineered with conservative safety margins against natural North Sea wave height fluctuations.”
Shell / Statoil Troll Engineering Team — offshore engineering consortium, Troll Gas Field Specification Documents
“An extra one meter of platform air gap above high-tide level is incorporated specifically to mitigate projected 100-year sea level rise resulting from global greenhouse warming.”
The Split:Publicly, platform elevations were described as routine wave-height margins. Privately, Shell spent millions raising the physical concrete deck of the gigantic Troll platform by a meter explicitly to survive the sea level rise it claimed in court was unproven.
Watch what companies pour concrete for, not what they file in lobbying whitepapers.
