Onshore structures

We closely integrate with our clients by understanding their specific challenges and needs. As long-term partners, we are often reappointed by our clients for the safe and timely implementation of fast-track projects.

Our full range of services spans from feasibilities study / concept development to the detailed engineering of the projects. Our highly experienced engineers, all with proven track record of major oil and gas projects, offer flexibility and reliability often exceeding our client’s expectation.

Eien has extensive knowledge and experience with the design, analysis and assessment of structures for the petroleum industry. We design solutions for onshore installations, terminals and pipelines for Oil & Gas and chemical plants.

We provide cost-effective structural design solutions focused on constructability, safety, and ease of installation.

App
Better design, faster delivery, cost effective solutions

We use building information modelling (BIM) to deliver exceptional value to our clients. BIM is a collaborative working philosophy that allows projects to be delivered faster, more efficiently and with significant cost benefits to our clients.

Explosion analysis and hazard management

Explosions can be critical to both the asset and its personnel. Our structural engineering specialists perform advanced explosion analyses to ensure sufficient structural capacity in all critical areas.

Cost estimation based on industry experience

With extensive experience in engineering solutions for the oil and gas industry, Eien provides highly qualified cost estimation. Our cost estimates are applicable throughout the project life cycle from early conceptual and feasibility studies to final design solutions.

Based on information about field output or facility capacity, our specialists develop flow diagrams, concept layouts and master equipment lists and Material Take Offs (MTOs). We have successfully developed the cost estimation for several green field and brown field projects.
