Wake gives maritime operators an independent, confidential comparison of measured crew sleep and recovery against watch schedules and official work/rest records. Act before fatigue becomes a safety event, an audit finding, or an operational problem.
Designed for fleet managers, marine superintendents, DPA/ISM teams, safety managers, and operators responsible for crew scheduling and fatigue risk.
Contact us See how the audit worksWork/rest records can be compliant on paper while crews still accumulate fatigue. Records show scheduled rest. They can't show whether it became sleep and recovery. A confidential, time-limited measurement gives your safety team the missing half of the picture.
In a 2025 Cardiff University study of over 1,200 cargo seafarers, researchers found work/rest hour records are often falsified to conceal overwork, and the UK's Marine Accident Investigation Branch has concluded that rest-hour records on board many vessels "are not completed accurately."

More than a third of cargo seafarers surveyed in that same study reported not getting enough sleep in the previous 48 hours, driven by long hours, irregular patterns, port duties, and vessel motion. Even where the Maritime Labour Convention is followed, seafarers can still be left without enough rest.

Working outputs. All findings remain your confidential property.
Where fatigue risk concentrates, by role, watch, and rotation phase.
Measured sleep and recovery set against official work/rest records, with the gap quantified. An analytical exercise; it does not determine legal compliance by itself.
How fatigue risk accumulates across a rotation, and where the curve bends.
Practical scheduling, watchkeeping, and rest-environment changes, with rationale.
What to measure again after changes, so you can tell whether they worked.
Each consenting participant gets a personal summary of their own data. This goes to the participant, never to management.
The deliverables answer your scheduling questions. The process itself does three more things.
A documented, methodical measurement program shows fatigue risk was taken seriously. Useful material for incident investigations, vetting questionnaires, and conversations with your P&I club or insurer.
Voluntary participation, private personal summaries for each participant, and an explicit no-discipline rule show crews the company invests in their welfare. In a seafarer shortage, that matters.
Knowing which roles and rotation phases carry the risk means changes can be surgical: adjust the watch system where the data points, instead of disrupting the whole operation.
A short onboarding, then a 4 to 5 week measurement window covering a full crew rotation where possible. You see the full methodology before signing anything.
We agree on vessel, watch pattern, participant group, privacy controls, and success criteria up front, so everyone knows what the audit will and won't answer.
10 to 20 volunteer crew wear a standardized, screenless sleep/recovery band for 4 to 6 weeks, day and night, in non-hazardous areas. Data is read alongside watch schedules, operational context, and official work/rest records.
We map patterns by role, watch, rotation phase, sleep opportunity, and recovery, and compare measured sleep and recovery against recorded rest. Your reporting is aggregate; individual results are never used for discipline or performance review.
You receive the heatmap, the measured-versus-recorded comparison, and prioritized recommendations. We present to your safety team and agree on a re-measurement plan to check whether the changes helped.
A fatigue audit examines the gap between recorded rest and measured sleep and recovery. It is designed so you can ask the question safely.
Participation requires written informed consent, and any crew member can withdraw at any time without consequence. Data gaps from opt-outs are disclosed honestly, never filled in.
You receive anonymized, aggregate reporting only. Individual-level data is never shared with the operator, and results are contractually barred from use in discipline, performance review, or employment decisions.
All reports are your confidential property. Nothing goes to third parties without your written consent, and the engagement can be commissioned through legal counsel as part of a safety review.
Encrypted storage, retained for 12 months after the final report, then deleted. No audio, location tracking, or message content is collected. Participants can request a copy of their own data and deletion at any time.
No. Consumer-grade wearables, not medical devices. Sleep and recovery figures are estimates for operational trend analysis, not diagnosis or fitness-for-duty decisions.
One standardized, screenless sleep/recovery band per participant, so measurements are comparable. Lightweight, 8-day battery, worn day and night in non-hazardous areas. Bands are factory-reset between engagements.
That's fine. Participation is voluntary, with written consent and the right to withdraw at any time. Missing data is disclosed honestly; nothing is interpolated or filled in.
No. The operator receives aggregate reports only, by role, watch, or rotation phase. Individual summaries go to the participants themselves. Using results for discipline or performance review is contractually prohibited.
In 20 minutes, we'll determine whether a fatigue audit is suitable for your vessel, what it would measure, and what information would be required. No commitment and no preparation required.
Wake is accepting a small number of founding audit engagements for 2026-2027. Founding clients work directly with the principal, and their operational questions help shape the methodology.
