A S Jessup-Bould: What I Can Do |
||
|
I can produce detailed Piping and
Instrumentation Diagrams representing equipment, interconnecting pipework, instrumentation
and control loops complete with tagging of instruments, line sizes, line
material / insulation, line fluid etc. |
|||
|
I
can produce heat and mass balances deriving them from either hand or
spreadsheet calculations as appropriate. |
|||
|
I can provide specifications in the form
of data sheets for most types of process equipment. I can provide process
information for instrumentation data sheets and produce system trip and
interlock ("kiss") charts. |
|||
|
Calculations In addition to heat and mass balance
calculations I have experience in a range of other process calculations:
These include; pressure loss (liquid and gas, including safety relief systems), heat transfer (exchangers, vessels, direct contact),
combustion (gases, liquids, solids), gas scrubbing and stripping,
distillation, utility requirements. |
|||
|
Equipment Specification and Bid
Appraisal I have prepared process specifications (eg
data sheets) and carried out technical bid appraisals for a wide range of
process equipment including; pumps, fans, heat exchangers, vessels, pipework,
columns, agitators. I have also provided process specifications for
instrumentation, control valves and relief valves. Specifications have generally included
definition of the process duty, process constraints or special
considerations, materials of construction, utility conditions. |
|||
|
|
|||
|
Hazard
Identification and Assessment I have experience in producing process
hazard and safety integrity assessments and the use of hazard severity
methods. I have applied these skills in fine chemicals and energy from waste
projects. |
|||
|
I can carry out hazardous area
classifications for flammable vapours and dusts. I have experience in using
BS5345 Pt2, BS EN 60079 Pt10, IP15, IGE/SR/25, BS6467 Pt2, BS50281-1-2. I have carried out hazardous area analyses
on coke works' by-products plants, sewage works (including digesters and
thermal hydrolysis plants), large battery installations, fuel storage and
natural gas applications. I have produced guidelines (in 1985 &
2001) and provided presentations on hazardous area classification for my
colleagues. I am aware of the need for risk assessments in the Dangerous
Substances and Explosive Atmospheres Regulations 2002 and have carried out
risk assessments where explosive atmospheres may be present. |
|
||
|
|
|||
|
I have both facilitated Hazard and
Operability Studies and participated in others as the Lead Process Engineer. As an independent Chairperson, I have
familiarised myself with Client's proposed processes, and their existing
practices in terms of plant design and operation before embarking on the
HazOp. As a result I have been able to provide appropriate guidance for the
Team enabling the study to be executed in an efficient manner. I am able to work with manual recording
systems and I have used Lihou HazOp software. |

|
|
|||
|
Pressure
Systems Regulations and Pressure Equipment Directive I have carried out the assessment of
pressurised systems to ascertain requirements for compliance with both the Pressure
Safety Systems Regulations (PSSR) and the Pressure Equipment Directive (PED).
I have checked manufacturers' PED assessments and ensured that the correct
documentation has been provided in accordance with PED. For PSSR assessments I have account for
the nature of the fluid, eg steam, compressed gas, its containment volume and
maximum working pressure. For PED I have taken in to account the
class of fluid contained by the equipment / pipeline / assembly, the size of
containment (eg volume or pipe diameter) and its design pressure. This has
enabled classification as either Sound Engineering Practice (SEP) or one of
the categories (I to IV) that require CE marking. The purpose of
classification being to determine, through the use of PED modules, the level
of inspection and control during manufacture, and the records to be kept. |
|||
|
|
|||
|
I have designed and checked safety relief
systems using API520/521, BS6759 and the IChemE Relief Systems Handbook. My work
has included determination of relief scenarios and required relief rates. I
have undertaken calculations for set pressure, checks for satisfactory
re-seat pressure, relief valve size and line sizing to meet acceptable inlet
and outlet pressure drops for relief valves / bursting discs. |
|||
|
I have raised the appropriate
documentation for the systems being considered, whether as part of a process
hazard assessment or through the use of RST forms. I have designed relief
systems for a variety of process fluids including compressed and liquefied
gases and for emergency venting of batch reactors. |
|
||
|
|
|||
|
|
|||
|
|
|||
|
|
|||
|
I have written operating instructions for
a variety of plants including sludge incineration and flue gas cleaning,
sewage sludge digestion and coke oven byproducts. |
|||
|
|
|
||
|
I have provided formal classroom and
practical on-the-job training for personnel at a number of process plants
including developing countries. These include tar and benzol refineries, coke
oven by-products and incineration. I have also provided training documentation
for flue gas cleaning and sewage sludge drying plants. |
|
||
|
|
|
||
|
I have had hands-on commissioning
experience both in the |
|
||
|
|
|
||
|
|
|||
|
Whilst working at Johnson-Hunt Limited I
provided programming expertise for their mechanical
design software. Furthermore I was responsible for administering the
Prime computer system used for engineering design and CAD. I am also versed in Microsoft Word, Excel
and PowerPoint as well as Lotus Notes, AmiPro, 123 and Freelance. I have had experience in the use of
proprietary software for process flow sheet simulation and heat exchanger thermal design. |

Heat
Exchanger Thermal & Mechanical Design I
can specify and carry out the detailed design of tubular and plate heat
exchangers. I spent over 3 years working as a design engineer for a leading |
|
||
|
I was also responsible for expanding the
company's in-house software library for mechanical design (eg shell and
nozzle design to BS5500, nozzle loadings to BS5500 and WRC, saddle supports
to BS5500). I also wrote software mechanical data sheet preparation which
enabled automatic extraction of stress data for use in mechanical design
programs. |
|
||
|
It should be noted that in-house
mechanical design software was not only subjected to in-house verification,
but the calculations performed using this software were checked by outside
agencies for insurance purposes. |
|
||
|
|
|
||
|
|
|||
|
I have provided Process Engineering input to
tenders in the form of process descriptions, writing of technical appraisals,
calculation of utility requirements and process guarantees. |
