Subsea & Mechanical Engineering Consultant
Design | Analysis | Assurance | Project Support
Lateral Engineering Solutions (LES) is a Texas-licensed engineering firm founded by Les Griffin, P.E., a subsea engineering veteran with nearly two decades of experience in offshore systems. We provide design, FEA, and consulting services to help operators, EPCs, and service companies reduce risk and deliver reliable results in extreme environments.
What We Do
Engineering Services for Subsea & Offshore Projects
Mechanical Design
Conceptual and detailed 3D CAD design using SolidWorks and Autodesk Fusion. Expertise in subsea hardware, ROV tools & interfaces, custom frames & lifting appliances, test fixtures, and heavy-duty equipment built for extreme loads and harsh environments.
Structural & Mechanical Analysis
Finite element analysis (FEA) using SolidWorks Simulation Premium to evaluate structural components and mechanical assemblies—including subsea hardware, tooling, and installation aids—for load capacity, integrity, and performance in extreme service conditions.
Independent Engineering Reviews
Objective technical assurance for mechanical systems. LES provides design reviews, compliance verification, and fitness-for-service assessments across fabrication and offshore operations.
Field & Fabrication Engineering Support
Practical engineering support that bridges design and execution. From vendor coordination to documentation and on-site oversight, we ensure readiness and reliability in procurement, fabrication, and offshore campaigns.
Deepwater Systems & Subsea Tools - Designed for Performance
LES supports the design, analysis, and readiness of critical subsea and offshore equipment. From drilling risers and wellhead systems to intervention tooling, we help ensure equipment is engineered, tested, and delivered to meet the highest standards for strength, fatigue, and field performance.
