Taking your project to the next level

ENGINEERING SOLUTION PROVIDER

We are engineering design consultants, providing services to wide range of clients ranging from

civil, automotive to oil & gas industry. We have more than 30 years of combined experience be-

tween us in various engineering sectors. We invest in our people and technology to make sure

our engineering capability is top notch. Our services are affordable with reasonable charges yet

we do not take shortcuts that compromise the integrity of our design, or our attention to detail.

At EDSIL, our clients’ complete satisfaction is of paramount importance to all of us.

TAKING PRIDE IN WHAT WE DO

"At EDSIL we aim to establish meaningful relationship with our clients which ensures the delivery of high quality, cost effective engineering solutions every time.”

“We are committed to serving our clients and providing the highest quality services

and innovative solutions.”

DRAUGHTING SERVICES

We provide engineering design and Computer Aided Design services, using the latest tools avail-

able to keep us abreast with the latest technology in the industry. We provide 2D and 3D CAD

draughting services that suit your needs at competitive charge. We invest heavily in our design

software and facilities including several plotters to print your drawing of up to A0 size paper.

• Metal forming analysis- large displacement, plastic flow,

transient analysis.

• Highly nonlinear-material and buckling nonlinearity.

• Examples shown in the pictures are the analysis of

metal forming of sheet and tube by laser scanning. The

analysis can be uncoupled into sequential thermal and

stress analyses The thermal problem is solved first to

obtain the temperature field, which is then used as ther-

mal loading for the structural problem. The same mesh

is used for both thermal and mechanical calculations.

The problem can be represented by only half of the

plate modelled with symmetric boundary conditions. The

temperature field caused by a moving laser beam is

transient in nature. Laser heating is modelled as moving

heat flux used to incorporate the laser beam motion.

The temperature-dependant material properties are con-

sidered including thermal conductivity, specific heat,

thermal expansion coefficient, Poisson’s ratio, elastic

modulus, yield stress and density. The temperature dis-

tribution, deformations, plastic strains and residual

stresses were analysed.

Transient Sequential Thermal-Structural Analysis

Apart from engineering and Computer Aided Design services, we offer in-house state-of-the-art

simulation services for the stress analysis of solids and structures in statics and dynamics. The

analysis can be linear (small strain, linear elastic materials) or highly nonlinear. We take your

ideas and an understanding of the conditions they will be used in and create a set of virtual ex-

periments to show how the design responds to real world situations. We can examine deforma-

tion, stress and strain response to loading, in single parts or in assemblies with multi part contact.

We can look at mechanical events, motion of parts, kinematics, and impact.

The following shows the magnitude of examples of analysis that we performed.

Contact Analysis

Linear & Non linear Static Analysis

• Linear contact (glued), frictional, fric-

tionless, offset etc.

• Various type of contacts (ie; rigid to

deformable, surface to surface, sur-

face to edge etc)

• Gasket analysis

• Examples shown in the figure are

gears meshing used in rack and pin-

ion system. Frictional contact were

considered between the gears. Cylin-

drical boundary condition was used

to model gear rotation, with fixed

radial and axial direction. Also pivot

joint for a construction tying applica-

tion.

• Material non-linearity (bilinear strain-

stress behaviour, hardening, etc.)

• Elastic to plastic material transfor-

mation

• Geometric non-linear buckling or

material failure

• Large displacements or rotations

• Non-linear boundary conditions

• Example shown in the picture is a

drive carriage parts for a 5 tonne

capacity lift. The FEA was vital part

of the design where it enhances the

structural integrity of the compo-

nents due to its extreme loading

conditions.

Before After



Oil & Gas –Offshore bleed ring

Problem

Verification of the structural integrity of a non-standard

bleed ring for oil rig application. The task is to provide

mechanical design calculation to confirm the adequacy

of the thickness of body, bolt load and gasket operat-

ing performance. Analysis should ensure that the bleed

ring can withstand the subjected assembly load and

vibration during normal operating condition.

Analysis

Taking asymmetric advantage only half of the adapter

is modelled. Bolts pretension on the adapter body is in

accordance with the API Recommended Torques for

flange. Bolts pretension on the nipoflanges is derived

from requirement in B16.5. The analysis has consid-

ered two time steps; 1. bolts pretension and 2. applied

internal pressure of up to 5000psi.

The stresses were compared to those allowed for the

material used and assessed against industry standard.

Outcome

EDSIL analysis showed that the the proposed body

thickness is sufficient to withstand the combination of

bolts pretension and internal pressure and working

within its strength capacity.





“Let us do the THINKING for you”

Marina Bay Sands - Mobile Cladding Access Plat-

forms:

We were asked to provide design for cladding access

platforms for what is now the worlds most expensive

hotel, Marina Bay Sands, Singapore. One of which

was a mobile suspended platform for to provide ac-

cess to the underside of the Sky Park 200m above

ground level. The platforms had to run on two tracks

embedded in the structural steelwork and the platform

had to be fully clad which meant wind loading would

be a major factor in the design.

The platform was modelled using beam analysis.

Loads combinations including high wind loading were

considered according to national standard. The plat-

form was made of aluminium profile, and therefore

BS8118 was used as a verification method.

Also, a bespoke mobile trolley was design for the sus-

pended structure. As this is a one of the critical item in

the system, the trolley design was also verified by

FEA.

Problem

To verify the structural integrity of a sheet metal board

in accordance with BS EN12811-2. The actual boards

of 1.5, 2, and 2.5m length were supplied to us for in-

house testing and verification.

Testing & Analysis

EDSIL has conducted a series of in-house testing as

required by the code. Comparing with initial hand cal-

culations, the boards failed against the initial design

concept of a locked seam. Having to reassess the de-

sign as behaving with a far more complex geometry

has been difficult. We have then conducted a shell fi-

nite element analysis and ignoring the locked seam

effect.

Outcome

We have finally been able to analyse the section in a

manner that allows the seam to slip. This has drasti-

cally reduced the theoretical board capacity to a point

below the tested results. With the test results now be-

ing moderately above the theoretical design capacity

the tests can now be viewed as proving the capacity of

the design. This is a requirement for passing these

boards as certifiable to BS EN 12811-3 and giving

them a partial designation in accordance with BS EN

12810-1 clause 5.
