Experience - Safety EngineeringWe are intending to post a complete set of data from one of the HSE sponsored large scale explosion tests here together with a FREE trial version of the powerful software required to interpret the results (Dynatool from CREA Consultants Ltd.). Also see the free sample software page Free Software We also have a number of
specialists available to help if required. 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.

for the generation of a large databases and negotiation software for use in
assessing a number of large insurance claims. Steve has also been involved in
the framing of witness questions for depositions to Court and the preparation of
presentation material for negotiation purposes. Relevant
Experience
– all
completed insurance claims were settled out of Court As part
of Logical Software's commercial and legal support activities, Steve Walker has
been responsible for the examination of the Safety, Management and Operational
issues resulting in loss and subsequent insurance claims. Sinking
of the P36 semi-submersible production platform offshore Brazil. 2001
– 2006 For this dispute between the Operating and Construction Insurers, Steve acted for the Design Contractors and construction insurers. It was necessary to examine all the design documentation in order to assess Safety and Operational issues along with documentation of events leading up to the loss. The
activities undertaken during the four years of the project included:-
Steve attended and presented at the dispute
resolution meeting for this claim. Dispute
relating to coating failure on the Sable Tier 1 Platforms.
2003
- 2006 Engineering
drawings were used to rigorously calculate and record the areas of the
structural elements (members and plates) for each platform. An assessment of the
severity and extent of damage sustained by area was performed from the
photographic evidence. All the above information was brought together in an
interactive database to enable negotiations to proceed. The
bottom line costs/durations and manpower requirements were derived using a
purpose built cost model. Nigeria
– damage to swamp facilities
2004
- present Following
willful damage to a number of oil/gas installations in the Niger Delta region,
Steve was engaged to perform the following activities:- · Engineering assessments – assessment of the status of the equipment items before and after the civil action and during on-going repairs. · Inclusion of information relating to the process and instrumentation systems. These
activities have involved the generation of a number of linked equipment
databases for each installation to aid in costing, inspection, condition
assessment and repair. Semi-submersible
drilling rig – thrusters repair
2003 Following
damage to a semi-submersible and claims for two sets of repairs and loss of hire
revenue, the scope was to identify the costs associated with the necessary
repairs, to the exclusion of costs associated with maintenance, betterment and
unnecessary support services. A
‘Negotiation Spreadsheet’ was developed to enable a flexible interpretation
of the information available and designed to allow the loss adjusters to examine
the options for apportioning the claimed costs during subsequent discussions
with the assured. Sable
– delayed start up claim
2005 Evaluation of the lost profits sustained by a Sable partner resulting from delayed start up of production. Cost models were developed to estimate the lost profits under a number of ‘start of production’ assumptions.
