Finglow Consultants Limited have recently taken on a new long term lease of the office premises at Beane Bridge House in Hertford. Our address and contact details therefore remain as follows:

Earlier this year, CEI of Blue Springs, Missouri, USA acquired Finglow Limited and Finglow Research Limited, owners and distributors of the ‘Finglow Software’ products. Although CEI continue to use the ‘Finglow’ name under a license agreement, Finglow Consultants Limited and CEI are entirely separate entities with no formal links or associations
Many people in the pressurised equipment industry will know the FINGLOW name from the respected pressure vessel design software that has proved to be one of the most popular tools for the pressure vessel and heat exchanger designer over the past 40 years.
Fewer people will know about the capabilities of Finglow Consultants Ltd (FCL), who offer a comprehensive range of engineering consultancy services to those involved in design, analysis, assessment and safe operation of pressurised equipment.
FCL’s lead piping stress engineer, Ross Hartwig, is well versed in the requirements of the ASME B31.3 process piping design code and has extensive experience in using CAESAR II piping flexibility analysis software for both static and dynamic loading scenarios. He is also an advanced user of ANSYS finite element analysis software and has specific experience in the use of non-linear limit load analysis methods to predict collapse and buckling failure modes in marine structures.
Ross’ areas of expertise also cover the design and assessment of subsea flanges, particularly where the risk of hydrogen induced stress cracking (HISC) requires consideration, and the application of rules in DNVGL-RP-F112 are essential to avoid the onset of premature HISC damage.
Please do not hesitate to contact us if you would like more details of how FCL could be of assistance to your organisation. Either go to the Get in Touch page on our website or call us on 01992 585450. Alternatively, if you prefer, you can contact Ross directly by e-mail at email@example.com or via his direct line telephone number - 01992 585451.
We'd like to take this opportunity to thank Clive Major and George Hering at Ibis Marketing Ltd, and Roger Bamberough here at FCL, for their combined efforts in developing our new website. We're delighted with the finished product and much appreciate the tenacity and patience that has been required of all of you to get us to this point.
We're really pleased to have played a key part on this project by substantiating the entire pressure boundary of FET's new LR class rescue submersible. If you have a few moments we'd recommend that you grab a coffee and take in the video. It's a fascinating watch !
Still lots of work to do but we're really proud to be working with JFD on these projects. To read the full article just click on the link beneath the photo.
Congratulations to Michael Travers, our new Mechanical Engineering Intern, on successfully completing a comprehensive online training course covering the design of pressure vessels to the requirements of ASME Section VIII Division 1.
Michael joined us in September 2020 having gained a BEng with First Class Honours in Mechanical Engineering from the University of Hertfordshire.
Although COVID-19 restrictions have meant that he has been obliged to work remotely throughout his time with us, we are looking forward to welcoming Michael to the office when we fully re-open later this year.
So good to see the first signs of spring at Beane Bridge House...
...and very lucky that a swan decided to get in on the act for the photo.
In the meantime work continues on our riverside garden, with the aim of restoring it to it's former glory.
Buckling is one of the most important failure modes to consider in pressure vessel design as it can lead to a sudden and catastrophic collapse. The animation below shows the first buckling mode obtained from a linear elastic buckling analysis of a ring-stiffened cylindrical shell subject to external pressure. Overall collapse of the structure is predicted principally because of the short shell bay length and slender stiffeners used.
The bifurcation buckling load is determined by constructing a linear elastic stiffness matrix and geometric stiffness matrix. Although this type of analysis almost always provides an overestimate of the real-world buckling load, a reasonable prediction of the actual buckling load can be obtained using a design factor depending on the requirements of the chosen design code. The linear elastic buckling analysis method offers a fast, low cost solution, as the smallest eigenvalue returned can offer a quick indication as to whether the structure will be stable under the required service conditions. It can also be used to highlight the regions of a structure in which stability issues could occur, as well as drawing attention to meshing irregularities that can themselves produce unexpected behaviour. Linear elastic buckling analysis does have inherent limitations, however. Due to being geometrically linear, the method can be a poor predictor of the importance of geometric imperfections. It also cannot take material nonlinearity into account, although this isn’t necessarily an issue if the applied loading doesn’t result in any appreciable yielding.
In situations where linear elastic buckling analysis is deemed unsuitable, non-linear buckling analysis can be used. In this type of analysis the load is applied in a series of steps and, as the load is increased, the shape and, in turn, the stiffness of the structure changes, resulting in a solution that accounts for geometry and material nonlinearity. Although such analyses are much more time consuming and expensive to run, with careful attention to material property definition and use of actual geometry, very accurate predictions of buckling load can be achieved.
We are delighted to announce that we will be welcoming a new member of staff to our office at the end of September.
Michael Travers will be joining us fresh from having achieved a first class honours degree in Mechanical Engineering from the University of Hertfordshire, and will single-handedly reduce the average age in the office quite significantly !!
We look forward to gradually introducing Michael to the wide range of project work that we are engaged on, which currently includes:
- the design of 500msw rated rescue submersibles for the Vietnamese, Korean and Chinese Navies;
- the design of FCC (Fluid Catalytic Cracking) process equipment for oil refinery revamp projects in Mexico and India.
An excellent opportunity to have a look around inside LR5. This was the first rescue submarine project that we worked on back in 2004 when we developed and substantiated the design of the new command module, battery pods and dry transfer skirt as part of a major refit project
2020 is our 25th year in business.
In recognition of this we have created an advert (see below) for inclusion in the July edition of BENCHMARK magazine that is published by NAFEMS (National Agency for Finite Element Methods and Standards).
Information about NAFEMS and the BENCHMARK magazine can be found here. We are members of NAFEMS and this advert gives us at Finglow Consultants Ltd a chance to share some good news with the NAFEMS community.
Some time ago now but this video is well worth a watch. We designed the entire cyclone system for normal operating temperatures in excess of 750°C, which included setting the support nozzle / cyclone hanger angles to minimise differential thermal movements throughout the system to less than a millimetre and initiating a design change to the vessel head necessary to limit 'sag' due to cyclone weight and vessel operating pressure.
