About Us >

Engineering Solutions

ECNZ brings together a team of skilled professionals across mechanical, civil, structural, electrical, instrumentation, and project engineering disciplines. Whether delivering oil & gas, power systems, civil & port infrastructure, or green energy projects, ECNZ applies unmatched experience, innovation, and practical solutions to every project.

Concept & Scoping

ECNZ works flexibly with clients — either delivering against pre-prepared scopes or collaborating directly to define required outcomes, constraints, and budget expectations. This ensures clarity from the outset and aligns design efforts with client priorities.

Feasibility

Studies

Our engineers investigate project feasibility and evaluate potential solutions against compliance requirements, providing clear recommendations and informed options to support confident decision-making.

Front-End

Engineering Design

Advancing a concept into FEED is critical to reducing design and construction risk. ECNZ delivers FEED solutions that provide clients with confidence in project outcomes, accurate cost estimates, and reliable construction timeframes, de-risking complex projects before execution.

Detailed

Design

ECNZ provides detailed engineering design for energy infrastructure, collaborating with constructors to ensure solutions are efficient, fit-for-purpose, and constructable. Designs are tailored to client and constructor requirements, with Safety in Design embedded throughout.

Construction

Support

ECNZ prioritises constructability to maximise efficiency and minimise cost. The team undertakes constructability reviews and provides on-site support, ensuring design anomalies or changes are addressed quickly and effectively, keeping projects on track.

Commissioning

ECNZ develops commissioning plans and provides commissioning engineers to ensure smooth, efficient start-up and handover of facilities, reducing risk and downtime.
