Engineering services for safety instrumented systems and plant data
Each service is sold as a fixed-scope package with named deliverables, a stated price and one review round. Work is delivered remotely from your documents, under NDA.

Three ways to engage
Most work starts as a fixed-scope package. Day-rate support and retainers suit teams that need capacity over a longer period.
Fixed-scope package
A defined deliverable, such as SIL verification of ten functions, at a price agreed before work starts. Includes one structured review round.
Day-rate support
Booked in days for work whose scope moves: design reviews, document checks, answering a contractor's queries.
Monthly retainer
A fixed number of days each month for consultancies and engineering firms that need overflow capacity they can rely on.
Who the work is for
Functional safety consultancies that need an extra engineer during peak periods. Engineering and EPC firms that need SIL verification, SRS and test documentation during design. Plant operators without an in-house functional safety team who need existing safety functions re-verified. Maintenance and reliability teams who want their plant data to answer questions.
Confidentiality and conflicts of interest
Every enquiry is screened for conflicts of interest before a proposal is sent. Work that would conflict with existing obligations is declined.
Client documents stay inside the engagement. Plant projects on this site are described without names, plant data or tag numbers, and the functional safety examples use illustrative data.
Fully remote
Calculations, specifications, reviews and procedures are delivered from documents. Nothing requires a connection to a live control or safety network. All work is delivered online, through shared documents and video calls.
