A logbook (a ship's logs or simply log) is a record of important events in the management, operation, and navigation of a ship. It is essential to traditional navigation, and must be filled in at least daily.

The term originally referred to a book for recording readings from the chip log that was used to estimate a ship's speed through the water. Today's ship's log has grown to contain many other types of information, and is a record of operational data relating to a ship or submarine, such as weather conditions, times of routine events and significant incidents, crew complement or what ports were docked at and when.

The term logbook has spread to a wide variety of other usages. Today, a virtual or electronic logbook is typically used for record-keeping for complex machines such as nuclear plants or particle accelerators. In military terms, a logbook is a series of official and legally binding documents. Each document (usually arranged by date) is marked with the time of an event or action of significance.

Shipping

Most national shipping authorities and admiralties specify that logbooks are kept to provide a record of events, and to help crews navigate should radio, radar or the GPS fail. Examination of the detail in a ship's log is often an important part of the investigative process for official maritime inquiries, in much the same way as a "black box" is used on airplanes. Logbook entries are sometimes of great importance in legal cases involving maritime commercial disputes.

Commercial ships and naval vessels often keep a "rough log", – or "scrap log" – a preliminary draft of the ship's course, speed, location, and other data, which is then transcribed as the "smooth log", – or "official log" – the final version of the ship's record. Changes may be made to the rough log but the smooth log is considered permanent and no erasures are permitted. Alterations or corrections in an official logbook must be initialled by the authorised keeper of the logbook and the original data entries which have been cancelled or corrected must remain legible.

Other logbooks

The V5C motor vehicle registration document in the United Kingdom is often referred to as the "logbook".

In the fishing industry, a logbook is used to record catch data as part of the fisheries regulations. It is then submitted to the fishing authorities of the vessel's flag state.

For amateur radio, the logbook is where the hams register their contacts and other radio operations. There are several programs to help radio operators in the management of their logbook.

Aircraft pilots must maintain a pilot logbook to record their time spent flying and in a simulator.

In New Zealand, a logbook is used to register driver and operator work time for commercial heavy vehicles.[1]

Two different logbooks for scuba divers.

In scuba diving, the logbook documents the experience of a diver by logging a diver's dives.

In skydiving, a logbook serves as a parachutist's personal history in the sport and also serves as an identifying document. It also provides drop zones proof to back one's skydiving licenses, ratings and currency.

A logbook recording a project which is compiled while it is being done may be called a project diary.[2][3]

Use in fiction

  • The Hornblower series mentions logs to explain plot development, or to make the story more realistic.
  • In Star Trek, the captain's log, a form of ship's log, is used to fill in the audience as to the events in progress, and acts as a diegetic form of soliloquy. This is part of a larger log system that includes personal logs (a sort of journal) and other officers' official logs, for stories that could not believably be reflected in the official Captain's log.

journal de bord

> I've been keeping a daily journal since 1993. I had my system in place until Blurb arrived with their custom journal/notebook option which I'm loving. A few thoughts on the matter.


Combo Papeterie + DayOne

Depuis (mettre date ici des premiers moleskine et DayOne), je m'organise sur différents carnets en papier (détails sur http://ducamp.me/Fournitures#Carnets_de_notes). Fervent du Leuchturm1917, je cherche une solution alternative pour personnaliser des carnets.


L’article 240-2.07 de la Division 240 décrit le livre de bord comme "un journal de bord contenant les éléments pertinents pour le suivi de la navigation et la sécurité du navire”

Reconstitution de la table à carte d'une frégate du XVIIIe siècle, avec au premier plan le livre de bord

Le livre de bord est un ensemble de registres (journal passerelle, journal machine, journal radio)[1] dans lesquels le capitaine ou les officiers d'un navire, consignent chronologiquement les différents événements, manœuvres, caps, observations et paramètres concernant la navigation, la conduite des machines, la réception et l'émission de messages radios. La liste d'équipage est notée dans le journal passerelle. La liste de passagers est un document à part. Le journal passerelle inclut les opérations de chargement-déchargement (y compris les marchandises dangereuses). Un éventuel problème médical est également noté au journal passerelle.

En cas de problème, le livre de bord permet aux inspecteurs ou experts de retracer le déroulement des opérations. Juridiquement, il fait foi jusqu'à preuve du contraire. On lui ajoute fréquemment le journal de mer, dans lequel le capitaine écrit ses rapports de mer. Il peut être complété sur les grands navires par un enregistreur des données du voyage, équivalent maritime des boîtes noires utilisées dans l'aviation, mais reste pour l'heure un élément important de la sécurité maritime. Les navires de petite taille peuvent regrouper les registres en un seul.

  1. Sur tout navire, le journal de mer prévu par la loi n° 69-8 du doit être complété du livre de bord coté. Ce livre qui peut comporter en annexe tout registre requis au terme du présent règlement (exercices, inspections, inventaire…) est visé chaque jour par le capitaine. Le journal passerelle, le journal machine et le journal radio constituent le livre de bord du navire.
  2. Les faits relatifs à la sécurité du navire en toutes circonstances doivent être consignés par ordre chronologique sur le journal passerelle, ainsi que les conditions météorologiques et tous les événements intéressant la sauvegarde de la vie humaine en mer.
    1. Les renseignements relatifs à la conduite du navire et à la tenue constante de l’estime doivent y figurer avec précision.
    2. Le capitaine y inscrit ses consignes journalières à l’usage des officiers de quart sur la passerelle.
    3. Le livre de bord doit comporter la liste de l'équipage, passagers et cargaison.
    4. l'heure d'appareillage.
    5. les prévisions météo et le temps observé et mesures prises.
    6. le cap suivi et vitesse à intervalles régulier.
    7. incidents, panne et avarie à bord.
  3. Pour la plaisance[2], le livre de bord (nommé journal de bord dans la réglementation Article 240-2.07) fait partie des documents obligatoires (matériel d’armement et de sécurité semi-hauturier).
