Parnell Manufacturing Facility Upgrade

Rectification of Humidity Control Systems, Stability Rooms and Central Cooling and Heating Systems

Parnell are manufacturers of veterinary pharmaceuticals with FDA and EMA accredited sterile manufacturing facilities in Alexandria NSW. Parnell produces products for animals such as dogs, dairy and beef cows, and horses.

EPES were engaged by Parnell to investigate and resolve long running humidity control issues within product stability rooms, humidity control, central heating and cooling systems and central Building Management System controls.

It was recognised that there were problems with the performance of the mechanical systems, however our involvement was required to develop a methodology and contract design for resolution.

Project Information

Location: Alexandria, New South Wales, Australia 
Client: Parnell Veterinary Pharmaceuticals
Engagement: Design Consultant
Sectors: Buildings, Pharmaceuticals
Services: Building Services, Commissioning Assistance, Construction and Design Consulting, Independent Reviews and Audits, Specialist Analysis
Year: 2016

The Problem

Unreliable system controls and mechanical services performance made demonstrating compliance challenging for the various critical certifications that the facility holds. Of primary concern were stability rooms which are required to control within tight limits for long durations of product testing, as well as the reliability of central heating and cooling systems in delivering humidity control to the various sterile rooms. 

Analysis and Implementation

EPES studied and tested the existing system to ascertain the shortcomings in system configuration versus what space conditions control was required for the certification process. Performance issues were identified, and design documentation prepared to enable rectifications works to be undertaken with supplementary equipment for humidification, greater reliability in controls and modifications to central heating hydraulics to improve flow circulation and availability.

EPES assisted the client in tendering the works, reviewing tender submissions and supervising the construction works with witness testing of the commissioning process for validation of performance in accordance with the design.

Outcome

The client achieved a predictable and reliable system performance following the works and greater control over the space conditions throughout the facility.

Taking time at the start of the project to study and test the existing systems enabled greater clarity in defining the rectification solution as well as ensuring that the contracted scope that was tendered was tight, mitigating cost escalation risks.

Kenya Water Treatment Plant – Brine Discharge Pipeline

Engineering Design

The Kenya Water Treatment Plant is located outside of Chinchilla in Queensland and treats by-product water from coal seam gas operations. Following the reverse osmosis (RO) process, reject is further concentrated in brine concentrators.

High temperature brine is discharged from the brine concentrators and is transferred via a pipeline to a storage pond. Various performance issues were related to the original design due to the elevated temperatures and corrosivity of the fluid.

EPES were engaged to design a replacement brine discharge pipeline to address the performance issues being experienced with the line. The objective of the design process was to ensure performance of the pipeline during discharge of elevated temperature brine discharge to the storage pond without impacting operation of the water treatment plant. Our scope included:

Year: 2016

The Problem

Several technical challenges exist with high temperature fluids in pipelines, particularly fluids with high chloride concentrations such as brine discharge. Non-metallic materials are typically unsuitable and metallic materials need to be carefully considered with respect to corrosion and durability of materials.

Pipeline leakage or rupture is not acceptable recognising the environmental risks.

Analysis and Implementation

Pipelines subject to elevated temperatures are designed in accordance with pressure piping standards to account for thermal expansion (temperature difference between non-operating and operating cases) as well as other static and dynamic load cases.

Once design loads cases are defined, the pipeline is subject to pipe stress analysis to ascertain both compliance of the pipeline allowable stresses, and primary support loadings to be used in the structural design of the secondary support system.  

Typical design considerations including liaison with stakeholders, safety in design, risk assessment and constructability reviews were incorporated into the design process. 

Outcome

The outcome for the project was a pipeline suitable for the intended duty offering users a robust and reliable transfer pipeline for delivery of concentrated brine to the storage pond. With careful consideration of the design requirements, durability issues, performance requirements and constructability, the pipeline offered a low impact construction with a superior outcome for the project.

Taking the time to properly understand the technical and construction constraints ensures that the project can be delivered within the stakeholder expectations in a reliable, practical and robust way.

Project Information

Location: Aimeliik, Republic of Palau
Client: Palau Public Utilities Corporation
Engagement: Detailed Design Consultant
Sectors: Industrial, Oil and Gas
Services: Commissioning Assistance, Construction and Design Consulting, Digital Engineering, Petroleum Engineering, Piping Engineering, Specialist Analysis
Year: 2017

The Problem

The existing pipeline was commissioned in 1983 from bare carbon steel piping and was showing extensive evidence of severe corrosion from exposure to seawater both internally and externally. Due to its exposed coastal location, significant undermining of supports from wave action was also evident.

Given the age and location of the existing facility, very little documentation was available to understand the design of the existing pipeline. Quality control of procurement and construction works is also a challenge in this region.

Analysis and Implementation

EPES with EIS undertook significant surveying works of the existing pipeline, geotechnical conditions and ground levels along the pipeline alignment. This was necessary due to the absence of original design documentation.

We then undertook detailed engineering design with a key focus on simplifying the construction process and addressing further risk of corrosion by specifying coating technologies suitable for the exposed environment.

Design documentation including 3D model, plan drawings and Technical Specifications were prepared in combined SI/Imperial units to aid in communication with local Contractors and Clients. EPES also offered technical advice in maintaining quality control and supervision of the procurement and construction works.

Outcome

EPES were able to deliver a high quality and detailed set of design deliverables that assisted the Client in tendering and controlling the Procurement and Construction works. The Client can rely on high quality documentation with an emphasis on ensuring that construction works is completed with a high degree of commercial control.

Good quality documentation and diligent preparation of design in brownfield environments offers a high level of commercial control (i.e. de-risking).

​1. New custom design retracting hood configuration designed especially for the side loading engine dynamometer

2. Required to remove high volumes of fumes and heat during testing

The Problem

The engines tested in Dyno 3 produce extremely high volumes of heat and fumes during dynamometer testing in the facility. The current arrangement in use at the facility is not effective and inefficient.

Project Information

Location: Rockhampton, Queensland, Australia
Client: Hastings Deering Rockhampton
Engagement: Engineering Consultant
Sectors: Buildings, Industrial
Services: Building Services, Commissioning Assistance, Construction and Design Consulting, Digital Engineering, Specialist Analysis
Year: 2017-2019

Analysis and Implementation

EPES analysed that a retractable hood arrangement was the preferred solution to enable the engine under test to install and removed easily, making the changeover process more efficient.

The ventilation system consisted of Two (2) exhaust fans at 35,000L/s each, and one (1) supply air fan at 30,000L/s as well as natural ventilation openings for removal of heat and exhaust fumes during testing. Large exhaust duct was reticulated within the constraints of the adjacent building structures.

Outcome

The resulting design was a robust ventilation system design that offered flexibility or engine change overs and included bypass air to overcome high temperature issues with mechanical equipment. Recognising the operational challenges was crucial to the success of this design, our engineers have previous experience working with dyno test facilities and were able to prepare a practical and functional design solution for a unique problem.

Unique and complex problems are best resolved by engineers with experience.

4. Ventilation calculations, equipment selections and controls

Sell and Parker required better ventilation for occupants of the space.

The Problem

The source of contaminants (smoke) was associated with plasma and oxy cutting, and existing ventilation provisions were inadequate. Significantly greater air quantities were required to maintain acceptable internal air quality. Generally, the ventilation system was subject to the requirements of Australian Standards.

Analysis and Implementation

Ventilation air quantity calculations were performed based on a required air change rate for the space volume and process. Ventilation equipment and ductwork was designed to maximise pick up and minimise additional noise whilst moving the additional quantity of ventilation air. Intake air was positioned to ensure clean air was drawn into the building.    

Outcome

Compliant ventilation system custom designed for the space and the cutting processes being used, whilst minimising impact to current operations.

Year: 2019

The Problem

Pressurised services are complex on large construction projects and can be high risk in the event of a failure. They can also be highly problematic for construction works if they do not perform as required by the demands of the construction process.

Recognising the size and complexity of this project, as well as a need to ensure consistency across the various construction fronts, the objective of this design was to collate and coordinate all of the variable pieces of information and perspectives and achieve a common approach to pressurised services installation.  

Analysis and Implementation

Several meetings with stakeholders in design, project management, construction and procurement were undertaken to collate the different ideas and information associated with the works. Design documents were developed, along with robust and practical engineering design to ensure consistency, standardisation and a clear path toward compliance with standards.

Outcome

Through this process significant commercial advantages were achieved through standardisation and sharing of plant and equipment, enabling early ordering of piping and valves and exploiting the opportunities of economies of scale. 

Undertaking early planning and design concept development, as well as opening communication with various stakeholders early in the project life cycle there are significant commercial benefits as well as reduced level of risk.

Identifying the correct design loadings, as well as risks associated with operation in a live construction environment were considered in the engineering analysis. Relative conservatism is this type of design package is pragmatic, whilst understanding the temporary nature of the works.

Analysis and Implementation

EPES performed analysis is accordance with the mandated standards and codes such as AS1170 for loading, AS4041 for pressure piping and AS4100 for steel structures. Close consultation with site construction enabled coordination with actual installation constraints as well as a means of clarifying design cases, limitations and risks. 

Outcome

The outcome was a comprehensive design package with appropriate levels of buy in from temporary works managers, site teams and procurement. Design documents were prepared well ahead of the being required for site works which enabled proper planning to be undertaken and communication to respective site personnel.

Well organised and planned design work dramatically reduces both technical, safety and commercial risks for all stakeholders on a project.

8LWR Seismic Analysis, Water Treatment Facility, Waikari, New Zealand

Mechanical Structural Analysis

EPES were engaged by Pall Australia to perform an earthquake loading analysis of the 8LWR structure designed by Pall for support of water treatment equipment in the Waikari region of New Zealand.

Analysis was performed in accordance with NZS 1170.5 Earthquake Actions New Zealand and AS/NZS 4100 Steel Structures. The water treatment facility is required to remain operational following an earthquake with a design life of 80 years.

EPES were to determine of the structure would satisfy the standards requirements for seismic loading in this region.

Project Information

Location: Waikari, New Zealand
Client: Pall Australia
Engagement: Specialist Finite Element Analysis
Sectors: Industrial, Water and Waste Water
Services: Construction and Design Consulting, Digital Engineering, Infrastructure Engineering, Piping Engineering, Specialist Analysis, Water and Waste Water
Year: 2019

The Problem

The region has high seismic activity and high design loadings were calculated due to the stringent requirements of NZS 1170.5 and the requirement for the water treatment facility to remain in operation shortly after a design seismic event. 

Analysis and Implementation

EPES utilised AS/NZS 1170.0 and AS1170.1 to determine design loadings for the proposed VR structure and MF module rack assembly. Design analysis was undertaken following NZS 1170.5 and application of Finite Element Analysis (FEA) using SolidWorks.   

Analysis determined that for the MF Rack Assembly, higher than acceptable deflections were evident in the analysis and that in order to satisfy the design criteria, additional bracing was recommended.  The VR frame was within acceptable limits.

Outcome

We identified deficiencies in the designed structure and methods required to rectify in order to achieve compliance with the local New Zealand earthquake design requirements. This was validated using Finite Element Analysis (FEA).
