Professional Practice, Ethics and Regulatory Compliance
This section tests judgement under commercial pressure: limits on your sign-off, honest disclosure, and knowing which code edition, permit and notification legally applies.
Core rules
- Public safety, health and welfare rank above schedule and employer profit. Sign or seal only work you are competent in and have personally reviewed; a seal is a personal attestation, not a departmental stamp.
- Disclose conflicts of interest in writing before advising. Keep client information confidential except where law or imminent danger to life requires disclosure; escalate internally first, then to the regulator.
- Negligence requires four elements: a duty of care, a breach of the reasonable-engineer standard, causation, and actual damage.
- Compliance is jurisdictional: the governing edition is the one adopted by the authority having jurisdiction, not automatically the newest. Work needs permits, inspections and as-built records before commissioning.
Worked example
A client asks you to skip the pressure test on a new vessel to protect a shutdown date.
- Identify the requirement: pressure-vessel codes require a hydrostatic test before service, typically 1.3 × maximum allowable working pressure adjusted by the lowest stress-ratio factor.
- Omitting it is a non-conformance, leaves a weld with no documented integrity record, and the operating permit depends on it.
- Respond in writing: decline the omission, cite the clause, and offer a code-compliant alternative - a pneumatic test with the prescribed exclusion zone and extra precautions - plus the schedule impact.
- Escalate to the engineer of record and the client's technical authority, and minute the decision.
Traps
'The client signs, so the risk is theirs'; sealing a drawing you did not check; accepting hospitality that creates obligation; assuming a superseded standard is acceptable because it was used before; relying on verbal approvals with no record.
