Fully cellular container vessel. This is a vessel designed to carry a full load of containers in fixed cell guides.
FEU. Forty foot equivalent unit. This is a unit used to measure the space available for containers. One standard size relates to the external length of the box being forty feet or 12.2m. The carriers in the United States emphasise the FEU whereas in other parts of the world the TEU, “twenty foot equivalent unit” is more accepted.
Feeders - Grain. When grain was carried in bulk, feeders were erected to feed the different parts of the holds or compartments, thereby filling any free space which might result from settling of cargo during the voyage. Grain in bulk may settle as much as 5 per cent during a voyage; therefore, measures had to be taken to prevent the shifting of grain because of the settling and the void spaces created.
First Open Water (FOW). This expression in a fixture report or in a charterparty refers to the date when a port is free from ice conditions sufficiently to allow ships to enter, load /discharge and leave. For example, a ship can be fixed to “ . . . load at First Open Water St Lawrence Seaway . . . ".
FILO (Free in liner out). If a charterparty states that the cargo will be loaded free of expense to the shipowner or other carrier but that he will pay for the discharging, the discharging is on liner terms (or "gross terms"), hence the use of this abbreviation.
Note that for financial accounting, the abbreviation can also refer to the manner in which stock is valued, "first in, last out". This has no relevance to chartering.
