About Us

Engineering that gets to the point.

Crux Energy Solutions is a Cypress, Texas-based consultancy firm delivering design engineering, analysis, and documentation for subsea and surface oil and gas equipment.

We work directly with operators, EPCs, and OEMs who need senior-level engineering without the overhead of adding headcount. Every deliverable is produced by the engineer doing the work — no hand-offs, no layers.

Our approach combines deep industry experience with modern computational tools to deliver results in days, not months. The work is done to recognized standards: API 6A, API 17D, ISO 13628.

What we deliver.

Subsea and surface engineering services scoped to your project requirements.

Design Engineering

Component and system design for subsea trees, connectors, valves, and actuators. Full 3D modeling with design verification to API and ISO standards.

Stress & FEA Analysis

Finite element analysis, fatigue assessments, and pressure-containing boundary calculations per ASME and API requirements. Clear, auditable reports.

Technical Documentation

Design verification reports, qualification test procedures, interface control documents, and engineering change packages ready for client or third-party review.

Surface Equipment

Wellhead, flow control, and production equipment engineering. Design modifications, repair procedures, and field-problem resolution for surface assets.

Subsea Systems

Subsea equipment design, connector qualification, and intervention tooling. Work scoped to API 17D and ISO 13628 requirements.

Standards Compliance

Gap assessments, design reviews, and compliance documentation to API 6A, API 17D, ASME BPVC, and ISO 13628. Independent verification available.

Technology

Modern tools. Faster delivery.

We leverage advanced computational methods and 3D modeling to compress engineering timelines. What traditionally takes weeks, we deliver in days.

Parametric 3D CAD with simulation-driven design
Advanced FEA and computational fluid dynamics
Automated drawing and documentation generation
Our Approach

Simple. Direct. Done.

No layers of project management between you and the engineer. Here is how we work.

01

Scope the Work

You describe the problem. We define deliverables, timeline, and fixed cost. No ambiguity on what you are getting.

02

Execute Fast

Senior engineering, no hand-offs. Direct access to the person doing the analysis and modeling. Questions answered same-day.

03

Deliver Complete

Final deliverables include calculations, models, drawings, and documentation. Formatted for your internal review or third-party audit.

Built for depths you cannot reach.

Subsea equipment operates where failure is not an option and field repairs are impossible. That reality drives every calculation, every tolerance, and every design decision we make.
