Incident Overview
Mobilisation Date:

28th April 2022

Location:

Cap Lopez, Port Gentil, Gabon

Cause:

Catastrophic failure of a crude storage tankreleasing 300,000 bbls (50,000m3) of Rabi crude oilmainly into the tanks bunded area

Response Type: 6 responders mobilized to provide technicalsupport, incident management and training of local
personnel

Crude contained mainly within the bunded area
High levels of VOC’s
prevented initial
response.
Once the VOC levels
were safe pumping
operationscommenced using
local resources totransfer the crude oilfrom bund to othertanks.
VAC trucks used torecover oil spilled
outside bund.
