Tier 2 #3 (Off Plot) – 14 March 2020 PROCESS SAFETY EVENT: What happened? 12” Pipeline Blind Flange Leak At a Remote Manifold Station a civil sub-contractor detected a leak by hearing a sound from inside the station. An operator visited the site and confirmed a leak from a blind flange in a dead leg of a 12” loop line. All connected wells were isolated and the line depressurized. The flange was opened, and both gasket and blind flange, showing signs of erosion-corrosion damage from scaling, were replaced. It appeared that earlier signs of a potential leak (through salt deposition found around the flange) had been observed but were not reported as the threshold limits of weep/seep leakages had not been met. How to prevent this at your site? Ø Ø Do you routinely check remote manifolds and other off plot assets for early leak symptoms. How do you ensure this is happening? Always report any indication of a leak even if it does not meet the weep/seep criteria Report any leak, even if it does not meet the weep/seep criteria Leaking point

Tier 2 #5 – 25 May 2020 PROCESS SAFETY EVENT: What happened? Crude Tanker Overfill During loading of crude oil from storage tanks into crude tankers, as the filling of the 1 st tanker had been finished, the operator started filling a 2 nd oil tanker from the 2 nd loading point, but forgot to close the isolation valve to the first (full) tanker. At a certain moment the tank supplying the crude to the 2 nd tanker ran empty and another tank had to be lined up. This also required the use of another loading pump. The discharge of this pump was lined up via a crossover valve to reach the 2 nd truck. However, that loading pump was also lined up to the 1 st tanker that was already full but had the valve left open, which resulted in an overflow of the tanker. How to prevent this at your site? Ø Ø Always before lining up equipment ‘walk the line’ to verify and validate the line up change. During crude tanker truck filling the level shall be regularly monitored Do not leave a critical transfer unattended (PSF-2)
