Our Team

Our key engineers include:

Jeff Kazazi – Director / Principal Consultant

Jeff graduated from the University of Western Australia in 1976 with an honours degree in Civil / Structural Engineering. The first 5 years were spent in the commercial, industrial and domestic sectors before moving into the oil, gas and resource industries.

Jeff has extensive experience in lifting and rigging systems, offshore brownfield projects, front end engineering design (FEED) and management of structural projects. This experience includes site attendance and close contact with fabrication and construction activities. He has been a member of a number of teams carrying out investigation of incidents and understanding the reasons behind such incidents.

Jeff is keen to solve engineering problems and seek innovative solutions to engineering challenges. “There is no job that cannot be done” but equally “the devil is in the detail”. His experience and knowledge gained over many years are incorporated into his work.

Len Sgherza – Principal Structural Engineer

Len has over 25 years of experience in structural engineering in the resource industry through all life cycle phases including concept development, specification development, front end engineering, software analysis, detailed design, verification, fabrication support, loadout design, seafastening design, lift design, on-site installation support, upgrade design, design verification, assessment for life extension and decommissioning. This has included design of primary steel and secondary steel on major greenfield projects in the North West Shelf, Timor Sea, Gulf of Thailand and Bass Strait as well as a variety of brownfield projects ranging from fast track resolution of issues impacting on production to planned long term improvements.

This experience has encompassed subsea structures, jackets, risers, topsides, FPSOs, support vessels, marine facilities and onshore infrastructure.

Len has a keen focus on customer communication, and regularly meets with customers to identify needs and develop effective outcomes. His broad base of experience enables him to quickly come up to speed with facility requirements for projects and identify key issues relevant to fabrication, installation and operation that need to be considered.

Stephen Keating – Lead Structural Engineer

Steve has over 14 years of structural engineering experience in the oil, gas and resource industries involving structural analysis and design, offshore construction and installation engineering, rigging design and heavy lift planning. Steve also has extensive experience performing on-site inspection and structural assessment of damaged and aging structural assets.

Having worked on a myriad of onshore and offshore facilities including FPSOs, Offshore Production Platforms and onshore LPG/LNG Facilities, Steve’s diverse experience includes work on buoys, topsides, risers, jetties, berths, LNG marine loading arms, pipe racks, pressure vessel support structures, temporary living quarters and subsea structures.

Steve’s dedication to quality and relentless drive to innovate has seen him involved in projects in the North West Shelf (Western Australia), Indonesia, West Africa, Qatar, Ireland, Norway and Timor Sea. Having experience working with Operators, Construction Firms and Design Consultancies in numerous projects around the globe, Steve delivers innovative and cost-effective solutions to clients.

Nick Birks – Lead Structural Engineer

Nick graduated from UWA in 1997 and has 18 years of experience in structural and civil engineering. He has worked in the resource industry since 2005 and has spent the majority of this time working on innovative projects that have met or exceeded the client’s requirements. These include the Cape Lambert Port B Temporary Works (Australian Construction Achievement Award 2013), North Rankin Drill Derrick Deconstruction and Honeywell PNG LNG Local Equipment Rooms – refer to the case study section for details of AEC’s role in these projects.

Nick is committed to a strong HSE culture and applies this to all aspects of his work. His approach to engineering design can be relied on for practical solutions that save time on the construction site.

Nick has recently gained sufficient exposure to the offshore oil and gas environment to understand the key drivers that lead to successful implementation of offshore brownfield projects. This has expanded his capabilities and he is now able to carry out concept/select phase studies for complex offshore projects such as replacement of platform cranes.
