What We Deliver Across the Full OT & C&I Project Lifecycle

At OTIS, we support every stage of an industrial project — from the earliest ideas on paper to long‑term operational excellence. Our approach blends deep technical expertise with practical, real‑world experience across energy, utilities, and complex industrial environments:

Feasibility & Concept Development

We help shape the foundations of your project with clear, strategic thinking:

• Defining operational needs and project direction

• Establishing OT, C&I, maintenance, and reliability strategies

• Developing high‑level control philosophies and system concepts

• Creating secure‑by‑design cybersecurity approaches

• Building early system architectures, network concepts, and control room layouts

• Producing conceptual budgets, execution plans, and design reports

• Providing independent technical authority and document reviews

Concept Design & Tender Engineering

We translate ideas into structured, tender‑ready engineering packages:

• Employer Requirements for DCS, SCADA, instrumentation, telecoms, and non‑control OT

• Instrument lists, datasheets, hook‑ups, and supporting documentation

• Architecture concepts, I/O estimates, and functional descriptions

• Cable diagrams, schedules, and termination details

• C&I inputs to plant layouts, PFDs, P&IDs, SDLs, and protection diagrams

• Hazard studies, SIL/LOPA assessments, and cause‑and‑effect development

• Interface matrices and packaged system requirements

• Detailed risk registers and maintenance/reliability requirements

• Ongoing technical authority support

Contracting & Vendor Engagement

We support you through procurement with clarity and confidence:

• Approved vendor lists for control systems and field devices

• Technical evaluation of tenders and supplier proposals

• Negotiation support and contract preparation

• Independent technical oversight throughout the process

FEED (Front‑End Engineering Design)

We ensure your FEED package is robust, aligned, and ready for execution:

• Full review of FEED deliverables

• Preparation of FEED‑level documents across all OT and C&I disciplines

EPC Delivery Support

We stay with you through execution, ensuring quality, compliance, and readiness:

• Participation in design reviews and technical workshops

• FAT and SAT involvement (systems and cybersecurity)

• Review of detailed design drawings and documentation

• Installation monitoring and supervision

• Commissioning criteria, cold/hot commissioning support

• Punchlist management and handover documentation

• System training and O&M manual development

• Continuous technical authority support

Operations & Maintenance

We help you run your assets safely, securely, and efficiently:

• Asset registers and technical summaries

• Standard operating and maintenance procedures

• OT maintenance frameworks and cybersecurity plans

• Compliance audits and regulatory reporting

• Reliability assessments and improvement strategies

• Ongoing technical authority and advisory support

Risk and Assurance

OTIS services are provided to mitigate technical, programme and compliance risk across industrial projects.

Because control systems often sit on the critical path, failures or delays can directly impact construction, commissioning and operational readiness.

Our approach ensures engineering integrity, regulatory alignment and secure-by-design implementation — safeguarding delivery from concept through to operations

Engineering Capability and OEM

At OTIS, all our services are aligned to recognised international standards and frameworks including:

• International Electrotechnical Commission IEC 62443 (Industrial Cyber Security)

• International Electrotechnical Commission IEC 61508 (Functional Safety)

• International Electrotechnical Commission IEC 61850 (Power Utility Automation)

• International Electrotechnical Commission IEC 61131 (PLC Programming Standards)

• BSI Group BS 6739 (Instrumentation in Process Control Systems)

Our approach ensures technical compliance, resilience, safety and secure-by-design principles across all project phases.
