Sinopec Shanghai Engineering Company Ltd. (Horizon Oil Sands project)
Charge
Failure to ensure the health and safety of workers under the Alberta Occupational Health and Safety Act (steel-erection / collapse charges).
Penalty
Convicted under the Alberta OHS Act following a multi-year prosecution; significant financial penalties and creative-sentencing orders imposed at sentencing.
Two ironworkers were killed when a partially erected crude-oil storage tank collapsed during construction at the Canadian Natural Resources Horizon Oil Sands site north of Fort McMurray. The case became one of Alberta's most-cited OHS prosecutions and reshaped how upstream operators audit major-construction contractor safety programs.
What we'd do differently
We treat structural-erection sequencing the same way an operator's PSC team does — engineered drawings on site, daily verification by a competent supervisor, and a written hold-point sign-off before the next lift. A clean paper trail at every hold point is the difference between an incident investigation that ends and one that grows.
