Glossary term Description
flatrack (flat) Container without side walls and roof, with fixed or collapsible end walls.
flexural strength The ability of a material or a construction to withstand bending.

Floating liquid natural gas (vessel). Similar to a FPSO except includes the separation and liquefaction of LNG. The vessel will be stationed at a gas field and will be able to separate and store condensate, LPG and LNG as liquid products for export

Flow moisture point (FMP) Point at which the goods change from solid to liquid state.

Free on board - seller of goods pays for everything until goods cross the ship's rail on loading


Flag of convenience, term that is often used to describe states that have a shipping register that is considered lax about its standards and conditions for seafarers on board ships

fore and aft stowage Load stowed along the length of the container or the ship. Contrast athwartships stowage. In the context of load securing, it is of utmost importance whether a container is stowed fore and aft or athwartships on a ship. In the case of athwartships stowage, the greatest acceleration forces act on the actual container longitudinally rather than transversely. Load securing measures must then be taken with this in mind.

Floating production, storage and offloading facility. Normally a converted tanker, although many are now purpose-built, permanently moored where some refining of crude may take place on board. Offload tankers may moor either alongside (parallel) or astern (tandem) or via nearby SBM and load cargo to be taken for further refining elsewhere. See also SBM, SPM


Distance between waterline and uppermost continuous deck (deckline). Not to be confused with airdraught

freezer container This is a special type of refrigerated container which can maintain the temperature of the cargo at approximately -65°C. At approximately -62°C, the "eutectic point" is reached, i.e. as of this temperature, all the water in a product is completely frozen. No microbial activity can occur when there is no free water, and therefore the product does not suffer any further loss of quality. At these temperatures, the product has an infinite storage life.
