HSE Group, Full field development (FFD) Kashagan field HSE            October 2006 – Present

The giant Kasahagan field is in an environmentally sensitive part of the Caspian sea with high reservoir pressures and with sour gas (H2S) at 15%. This part of the Caspian is Ice covered in Winter. The development will produce 1.5 million barrels per day in full production.

During concept selection (to November 2007) the project team has selected novel contained process solution founded on rock islands. 

Responsible for engineering safety aspects of fires, explosions and toxic releases. Development of QRA rule sets for contained toxic process plant by consequence analyses relating to toxic gas dispersion, fire loading/response, risk management of internal explosions. 

Development of systems to manage compartment toxic gas releases, HVAC and ignition prevention. 

Other duties include, review of engineering design documents, development and maintenance of the hazards and effects register the basis of the Shell ‘HEMP’ system and QRA analysis of the production ‘hubs’ and minimum facility well-head platforms.

AGIP – Kashagan Design of explosion proof enclosures

Project Manager of this £0.25 million, 3 month project to design explosion-proof enclosures for the process facilities. The sour (H₂S) nature of the gas at the Kashagan field has meant that a re-assessment of the layout of the field has been necessary to reduce the operating risk and availability of the planned facilities. One solution was to enclose the process units consisting of pile supported barges, pre assembled units and modules founded on artificial islands. These enclosures must contain gas releases, fires and explosions as well as protecting plant under maintenance from the impact of these events on neighbouring enclosures.

The project team designed a number of enclosures to resist overpressures up to 8 bar to a level suitable for Feed.  Design and analysis of the enclosures was performed using SACS and ABAQUS. Constructability, transportation and installation issues were also addressed leading to cost estimates for this solution.

HSE/BP - Response Spectra LSL has just completed a project to develop Explosion Response Spectra. The main Objective was to derive static design pressures for sizing main structures and barriers. The HSE have supplied all the Spadeadam explosion test results and BP have supplied the corresponding FLACS simulations. Steve was the Project Manager for this project.

HSE - Sensitivity of response of offshore structures to fire and blast 1995 - 1996

Project Manager of a major study of the sensitivity of response of structures to explosions, fires and combined fire and explosion scenarios. The Direct Probability Method was developed and used to develop response surfaces and calculate directly probabilities of failure and other reliability measures. These measures were used to rank the resistance variables in order of importance.
