About Us
Decades of Field-Proven Expertise
At James Square Energy Advisors (JSEA), we believe that the most complex technical challenges require more than just data; they require the perspective of a seasoned practitioner with plant commissioning and operations experience.
Founded in 2010 by J. Mark Landrum, P.E., JSEA provides a level of responsiveness and tailored attention that massive consulting firms simply cannot match. Operating as an independent operations and safety consultant, Mark serves as a direct, senior-level resource for his clients. With a career spanning four decades (from on-site construction management to testifying in state and federal courts), Mark offers the rare combination of deep-bench technical knowledge and the clear, authoritative communication necessary for high-stakes dispute resolution.
Our Core Service Areas
Expert Witness & Dispute Resolution
Providing authoritative technical and safety analysis and testimony for complex litigation, including process licensing, patent infringement, trade secret theft, and industrial accidents. We bridge the gap between technical complexity, codes, and practices in industry, and the provisions of relevant contracts for the design and construction of process facilities.
Process Safety Management (PSM)
Protecting your assets and reputation through rigorous safety audits, risk assessments, and the development of OSHA-compliant PSM programs. We specialize in identifying hazards before they become headlines.
Project Advisory & Owner’s Representation
Helping ensure that large-scale capital projects are executed on schedule and with precision. From conceptual design to commissioning and start-up, we act as your technical eyes and ears during the design phase, contract negotiations, and on-site construction to mitigate risk and prevent cost overruns.
High-Stakes Experience. Proven Results
Strict confidentiality is maintained for all clients. The following highlights represent the scope and complexity of our work.
