Oil major Shell has been handed an improvement notice by the HSE (Health and Safety Executive) after a gas leak earlier this year.
The company launched an investigation in January this year after a suspected gas leak near to the Curlew FPSO(Floating, Production, Storage and Offloading) vessel in the North Sea.
Shell has now been ordered to make improvements by the HSE following the incident.
Siem Offshore said it had received early termination for the vessel Siem Carrier after Petrobas failed to obtain an operating licence for it.
The company said the termination fee was not applicable to Petrobras as the vessel was blocked by a local tonnage.
