Logbooks

The ship app keeps the logbook working when the vessel loses its connection. Entries are created, completed, corrected and ended offline, with comments and attachments, and are sent in the order they were made once the connection returns. A change that clashes with the server, such as one to a day signed meanwhile, waits for a decision on board.

Signing a day needs the connection, and only once the device has sent every change for that day.

Some events run for a while: a pilot on board, a sea passage, an ECA transit, a fuel changeover, a breakdown. The start entry stays ongoing until End Task logs its paired end entry, often with the subject already filled in, and deleting the end entry reopens the task.

The bridge records watch handovers with the watch team, position fixes, noon reports, weather observations, course changes, anchoring, mooring and pilots. The master's standing, night and company orders are logged, and each officer's acknowledgement is an entry of its own. Weather observations can be filled in with the current weather at the position, then corrected.

The engine room records machinery readings, tank soundings, bunkering, fuel changeovers and breakdowns. The daily fuel consumption is logged per consumer with the fuel remaining on board, checked against the previous entry and what was bunkered since, and it is the source of Voyage's emissions figures.

Part I records the oil and oily-water operations of the machinery spaces: bilge water discharged overboard or automatically, oil residue (sludge) disposed of or incinerated, fuel tanks ballasted or cleaned, overboard valves sealed, and the oil filtering equipment's failures. Part II records an oil tanker's cargo and ballast operations, from loading, unloading and crude oil washing to slop discharge and the oil discharge monitoring equipment.

The Garbage Record Book keeps Part I for garbage and Part II for cargo residues that count as garbage: discharged into the sea, landed to a reception facility, incinerated or lost by accident, by category. Sewage and graywater discharges are logged too. The Ballast Water Record Book records each uptake, treatment, exchange and discharge, and the ballast water management system's failures.

For ships carrying noxious liquid substances in bulk, the Cargo Record Book records loading, unloading, internal transfers, mandatory prewashes, tank washings and their discharge, and the surveyor's control.

The EGCS Record Book records when the scrubber starts and stops, its malfunctions and its residue. ECA entry and exit open and close the vessel's transit of an emission control area, and shore power connections are logged, as is a port call at berth without shore power, with the FuelEU exception that applies and the fuel burned instead.

The radio log records the daily, weekly and monthly tests of the GMDSS equipment, battery capacity tests and surveys, distress, urgency and safety calls, work on the equipment, and the radio operators who join and leave.

The ODS Record Book records refrigerants and halons recharged, repaired, released, landed or supplied. The Biofouling Record Book records hull and niche area inspections, in-water cleaning and risk monitoring under the IMO biofouling guidelines.

In the office, a map shows each vessel at its latest logged position, heading the way it was going, faded when that position is over 24 hours old. Choose one vessel or several to see their tracks over the last 24 hours to 14 days, with arrivals, departures, anchorages and bunkerings marked, and open any point's entry from the map.

The office reads each vessel's logbook day by day, grouped by event, activity, record book or status, and adds comments and files to any entry. No office screen creates or changes an entry: the log stays the ship's.

Each rank on each vessel gets view or edit access to the logbook, and the rights to sign or unsign a day are given separately, so the company decides which ranks keep the log and which sign it.
