Seniorofficerseksamen (Skibsfører) common mistakes
Seniorofficerseksamen (Skibsfører) · Understand the traps and how to avoid them.
At the medical examination the candidate treats the colour-vision requirement as a formality and reads the Ishihara plates from memory or under poor cabin lighting, then cannot explain which certificate limitation (e.g. 'must not serve as lookout at night' or restriction on watchkeeping) follows from a failed colour-vision test.
Colour-vision and vision standards in the lægebekendtgørelse are tied to specific service limitations, but candidates memorise 'passed/failed' instead of the consequence. They also confuse the requirements for the health certificate (søfartslæge) with the separate requirements for the radio/telegraphy certificate.
What to do instead
Learn the structure of the health certificate: which examinations are mandatory (vision incl. colour vision, hearing, general medical), the validity periods for different age groups and service areas, and exactly which limitations a colour-vision deficiency triggers for deck vs. engine officers. Practise describing the limitation in your own words, not just naming the test.
The candidate answers questions about who may issue or renew a health certificate and what happens when a medical condition arises during a voyage by guessing, e.g. assuming any doctor can issue the full certificate or that the master can extend a lægeattest indefinitely.
The rules distinguish between the candidate's own doctor, an approved maritime doctor (søfartslæge), and the situation where the master must arrange a new examination at the next port. Candidates blur these roles because they revise only the pre-sea medical, not the ongoing validity regime.
What to do instead
Build a one-page table: who issues, what validity, what happens on expiry mid-voyage, and the master's duty to send the seafarer for examination at the next port. Anchor each row to the specific provision in the lægebekendtgørelse so you can state the rule and its source.
When asked about renewal or re-acquisition (generhvervelse) of a sønæringsbevis, the candidate gives the general renewal rule but cannot state the conditions that apply after a long lapse, after a suspension, or after a period without valid fartstid, and mixes up which document is being discussed (sønæringsbevis vs. kvalifikationsbevis vs. anerkendelsesbevis).
The bevis family looks similar on paper, and candidates revise the initial issue path only. The re-acquisition rules (documentation of sea service, refresher requirements, possible re-examination) are the part that is actually tested, and they differ by certificate type.
What to do instead
Make a comparison grid with rows for sønæringsbevis, kvalifikationsbevis and anerkendelsesbevis and columns for issue, renewal, upgrade and generhvervelse. For each cell write the concrete condition (sea service, courses, examination) and the authority involved. Recite the grid aloud until you can distinguish the three documents without hesitation.
The candidate describes the sea-service requirement for an upgrade (opgradering) as 'enough time at sea' without specifying the required service in the correct capacity, the required watchkeeping or bridge service, and how service in a lower grade is counted.
Fartstid rules are written as combinations of total service, service in a specific capacity, and approved watchkeeping, and candidates remember only the headline number. They also overlook that service must be documented in the søfartsbog with the correct sign-on/sign-off entries.
What to do instead
For each certificate grade write the exact fartstid formula: total months, months in capacity, watchkeeping requirement, and which types of vessel service count. Then check your own søfartsbog entries against that formula and note any gaps you would need to close before applying.
The candidate treats service in the Danish Navy (Søværnet) or on other non-merchant vessels as automatically equivalent to merchant sea service, and cannot explain what documentation or assessment is needed for such service to count.
Candidates assume 'time at sea is time at sea'. In practice naval service must be documented and assessed against the requirements, and only certain service (e.g. watchkeeping on qualifying vessels) is credited. The documentation route is different from ordinary søfartsbog entries.
What to do instead
Learn what documentation Søværnet service requires (service records, vessel type, capacity held) and which parts are credited toward which certificate. When answering, state the principle: service counts only if documented and assessed as equivalent, and name the authority that decides.
The candidate confuses the radiobevis (GMDSS radio operator certificate) with the general certificate of competency, assumes it is renewed on the same cycle, and cannot say which GMDSS sub-certificates or courses are prerequisites for the deck officer certificate.
The radio certificate is issued under separate rules and has its own validity and renewal regime, yet it is often studied together with the sønæringsbevis. Candidates therefore merge the two and lose marks on the specific renewal and course requirements.
What to do instead
Separate the two in your notes: issue authority, validity, renewal conditions and required courses for the radiobevis on one page; the sønæringsbevis on another. Explicitly note which GMDSS course or certificate is a prerequisite for the certificate you are applying for.
When asked about crew complement (besætningsfastsættelse) the candidate answers with a generic 'the ship must be safely manned' and cannot explain who determines the complement, what the determination is based on, and when a dispensation is required or may be granted.
The safe-manning principle is easy to state but candidates skip the procedure: the determination is vessel-specific, considers trading area, automation and emergency duties, and is documented. Dispensation rules have their own conditions and limits.
What to do instead
Learn the procedure as a sequence: who applies, what documentation (manning plan, watch schedule, emergency duties), who decides, and the conditions and time limits for dispensation. Practise explaining a concrete example, such as a short-handed vessel on a short coastal voyage, using the correct terms.
The candidate discusses MLC as a general 'seafarers' rights' topic and cannot connect specific requirements (employment agreement, hours of rest records, repatriation, complaint procedure, accommodation and food standards) to the master's and company's concrete obligations and to survey/certification.
MLC is often revised from summaries that list headings without the operational duties. Candidates then recognise the topics but cannot say what the master must actually do, record or display, or how the certificate and survey regime works.
What to do instead
For each MLC title write one concrete master/company action and one piece of evidence (record, certificate, posted notice). Then link them to the maritime labour certificate and the survey cycle. Answer practice questions by naming the action and the evidence, not just the right.
On safety and survey questions the candidate answers from the general ISM/safety-management narrative and cannot distinguish the statutory survey regime (initial, annual, intermediate, renewal, and the associated certificates) from ISPS certification and from class surveys.
Survey types and certificate validity periods are detailed and easy to blur, and candidates revise the safety culture narrative rather than the certificate structure. ISPS and statutory certification are then merged into one undifferentiated 'the ship is certified'.
What to do instead
Draw a timeline for a vessel's five-year cycle showing each survey type, its window and the certificate it supports, then a separate short timeline for the ISPS certificate. For each entry note who surveys and what happens if a survey window is missed.
When handling a scenario involving dangerous goods or an accident at sea, the candidate jumps straight to the emergency response and omits the documentation and notification chain: the dangerous goods declaration and stowage/segregation check, the report to the authority, the accident investigation duty, and the records to preserve.
Scenario questions reward a complete sequence, but candidates rehearse the dramatic part (firefighting, evacuation) and forget the paperwork and notification obligations that the examiner is testing. Dangerous goods segregation and declaration checks are also frequently skipped.
What to do instead
For each scenario type (dangerous goods incident, collision, grounding, personal injury) memorise a fixed sequence: immediate action, notification to whom and how quickly, records and evidence to preserve, and the report/investigation that follows. Rehearse the sequence aloud so the documentation step is never omitted.
