AES provides Pressure Vessel designs with in-house engineering and extensive experience in design, analysis and certification of vessels used in diving systems, refineries, chemical plants, power plants, nuclear plants and other processing facilities.

AES team have been appointed several Pressure Vessel for Human Occupancy (PVHO) projects and also have been involved with vertical and horizontal process vessels such as separators that are used in the Oil Treatment applications with the capability of handling large slugs of liquid.


Seven (7) different 445psi rated Saturated Diving System projects put AES into a unique position with regard to pressure vessel design.

Pressure Vessels deployed to Oil Rigs and mobilized on Diving Support Vessels require to be designed with additional design loads in order to survive the transit, operational and non-operational conditions under maximum operating pressure. Such pressure vessel designs for human occupancy specifically designed for offshore operations account for the mating vessel loads, such as punch, tension, bending and torsion loads in addition to the dynamic accelerations of the supply vessel. Design

AES completed seven (7) different 445psi rated Saturated Diving System projects which puts us into a unique position to design pressure vessels for offshore applications. The challenge with such projects is not to meet the ASME Section VIII rules only but also to meet the rules of ABS Underwater Vehicle, Systems and Hyperbaric Facilities rules for the external mating and dynamic acceleration loads of harsh offshore vessel operations in Sea State 5 and above conditions.

With years of practical work in the industry, AES offers solutions for pressure vessel projects that have mission critic requirements.

Using the state of the art Coadware Compress, ANSYS FEA and hand calculations in accordance with ASME Section VIII Div 1 & 2 rules AES has delivered several pressure vessel projects for

1.     Tall Columns,

2.     Vertical Pressure Vessels,

3.     Horizontal Pressure Vessels,

4.     Spherical Vessels,

5.     Heat Exchangers,

6.     Filters

We have experience in designing pressure vessels in accordance with

1.     ASME Boiler & Pressure Vessel Code, Section VIII, Div. - 1, Div. - 2 and Div. – 3,

2.     ASME I - Construction of Power Boilers

3.     ASME II - Materials

4.     ASME III - Construction of Nuclear Facility Components

5.     ASME IV - Construction of Heating Boilers

6.     ASME VIII-1 / VIII-2 - Construction of Pressure Vessels
