Actions from Previous FSA and Competent Authority Reports
A FSA Stage 2 was conducted on 19
th
June 2008 by Chevron (previous company name of
Valero). This assessment of the design was conducted for all Valero terminals as the design
intent was identical. No actions remain open from this assessment.
A FSA Stage 3 was conducted by way of a compliance document between March 2009 and
March 2010 the final issue being revised post installation. No actions remain open from this
assessment.
With regard to FSA Stage 4, Valero were in the process of conducting Stage 4 assessments
when the decision was taken to either sell or de-commission the terminal, so a FSA Stage 4
has not be conducted at the Shoreham Terminal.
In December 2012 a FSA Stage 5 was initiated for the de-commissioning of the SIS, this FSA
was only partly completed as Valero then sold the terminal as opposed to de-commissioning.
No actions are therefore relevant to the SIS.
On 30
th
July 2014 an assessment was conducted by the COMAH Competent Authority.
Nine actions were raised from the assessment of which:
actions one to seven were related to functional safety,
action eight related to Automatic Tank Gauging system which provides a layer
of protection albeit the system is providing a safety function of low/undefined
safety integrity as defined in HSE/SPC/Technical/General/51.
Action nine related to DSEAR.
The functional safety actions are detailed below, however, not to duplicate with other control
documents the action history is not detailed in the assessment, other than showing action
status.
Action control for this FSA is conducted utilising a live action tracker called ASANA. This
allows up to date status of all actions. A snapshot from ASANA will be appended to this FSA
for the status of each action relevant to the issue of the FSA.
