PRACTICAL SHIPPING VOCABULARYIncludes acronyms & names of organizations & non-profit bodies.
(For the purpose of this list only all the classification socieities will considered as non-profit societies)
WARNINGSBesides a succint or more developed explanation of items listed, some practical comments have been added. The choice of the terms listed is that they are in use on board commercial ships and should be part of the general knowledge of deck or engine officers, among many others. Terms and acronyms are permanently changing, errors are often found even in the most famous BA publications (ie: IBC Code). Therefore this list will be constantly updated, time and resources available, and the source(s) of the information will be mentioned when available. Any corrections or suggestion for improvement are welcome.Please Email them to [email protected]

Aframax Average Freight Rate AssessmentIn the past the largest tankers, now crude and product tankers with a deadweight between 45,000/70,000 and 80,000/100,000 tons.
Aldis lamp Aldis lamp Lamp with focused beam used for signaling with the morse code and which can be seen at a
distance of up to 20 miles. It was connected to the ship emergency electrical system in order to remain functioning when the main electrical power was down. Although its use as a communication device became rare due to the VHF, it is still very usefull to attract the attention of other ships at night.
ALRS Admiralty List of Radio Signals British admiralty publications (8 volumes, some of them in double or triple books) informing the navigators about all the radio stations and various kind of broacasted informations such as time signals, weather & navigational warnings, positioning systems, VTS procedures and many other. They are regularly updated through the weekly published Notice to Mariners, but this work is time consuming and the actual small staffs have hardly any time to do it. An affordable electronic publication with online updating is badly needed.

AWIWL Always Within Institute Warranties Limits For insurance purpose: the ship should sail only within sea areas in which she is always insured. For instance the Bearing Sea is outside these limits, while the southern part of it is almost always free of ice. Anyway the underwriter are often asking an extra premium to enter it.
Bravo
B B = signal letter and flag. Morse = ( - . . . ) Burgee flag= Red.When hoisted singly from a ship it means " I am discharging / loading explosives or flammable substances". Still widely used when bunkering.

BUTANE ButaneSee C4H10
BWT Bleeding Wing Tanks.In order to load the ship to full capacity with grain, the top ballast tanks are sometimes used as cargo spaces. Bleeding holes, normally closed by a flange when the tank is ballasted, allow the cargo to fall in the hold underneath, filling all the space available. This method of loading however involved a lot of extra preparation work, and a lot of cleaning work after the discharge.

DNV Det Norkse Veritas classification ASNorwegian Classification Society
DO Diesel Oil.Mainly used to run the auxiliary engines/alternator which provide the electrical power. On many large ships it used in the main engine during the maneuvers (berthing/sailing). When the main engine is stopped for a long time it is better, on some ships imperative, to have DO in all the system.
DOC Document of Compliance(ISM Code) Certificate provided by the Administration stating that the Owner/Management complies with the ISM Code
DOPDOSP Dropping Outward (Sea) Pilot (time)When the vessel leaves the last discharge port. It is often the time used as the end of a Voyage charter.
DOUGHNUT HOLES Doughnut Holes In Alaska these are water areas inside the chain of outer islands which are classiffied as "International waters" because they are further than 3 miles or 12 miles from any shore line, but they are entirely surrounded US territorial waters. (Lloyd's list A-52) Some ships are taking advantage of this legal trick to get rid of wastes which have otherwise to be dumped at sea at the same distance from shore. For many purposes the US uses the 3 miles limit for its territorial waters, which makes that these Doughnut Holes can also be found on the Gulf of Mexico coast.
DP Designated Person.For the ISM Code, any member of the Owner's staff who is aware of the problem of the vessels, and who has a direct access to the top management.
DSC Digital Selective Calling GMDSS System: MF/HF/VHF facility which allows for automatic access to coast stations equipped with the system. A short list to select the quickly the nature of distress is available, unfortunately the "pirate attack" had been forgotten, while it is one which need a a maximum of automation, and discretion.
DWT or DWCC DeadWeight Cargo CapacityWeights of the cargo which can be lifted, usually expresses in metric or long tons. Not to be confused with the deadweight itself which includes many other weights: bunkers, fresh water, provisions, stores, ballast, constant. They can add up to a few thousands tons on a Panamax bulker.
Echo
E E = signal letter and flag. Morse = ( . ) Flag= Blue over red.When hoisted singly from a ship it means "I am altering my course to starboard.
ECDIS Electronic Chart Display and Information SystemBased on vectorial representation of features, this system is the best available as it can be coupled to many other devices. Unfortunately since the availability of GPS positioning many hydrographic information have be found to be out of position by several miles at times (ie : Providence channel in the Bahamas), therefore many charts must be redrawn. It is only with these charts that electronic facilities, such as automatic alarms for shallow water, can be connected.

E&OC Errors & Omissions Excepted (Such as this list)
EPIRB Emergency Position Indicating Radio Beacon Small buoyant transmitter which should always remain afloat if the ship sinks, and send automatically a distress message via satellites.
EQUASIS EQUASIS European ship and operator information system which becomes operational in May 2000. Based on a French system, it will be an important tool for anybody with an interest in or responsibility for maritime safety, to select ships of high quality, and also an useful tool for PSC inspectors. (Commission of the European Communities). It will be really efficient when seafarers will be able to rely on it to have a good idea of the effective seaworthiness of the vessel to which they are sent by crewing agencies.
ETA Estimated Time of ArrivalSome agents assume it is the Expected Time of Arrival, or even the Exact Time of Arrival, so they are upset when the ship cannot keep the schedule. At times they require the "Earliest ETA", which is more reasonable. This time must be transmitted quite often to other services also: pilotage, shipowner, authorities, VTS...
ETC Estimated Time of CompletionEstimated time of completion of the cargo operations. Normally the agent should ask the captain how long he requires to make the ship seaworthy after the ETC. Very few agents adhere to this, order the pilot and the tugs for the ETC, and have to pay huge waiting times to these services if the ship needs more time to be ready.
ETD Estimated Time of DepartureEstimated time of departure of the vessel. Does not necessarily coincide with the time of completion for the reasons evoked here above, or because the ship has to wait for another reason: tide, daylight,...
ETR Estimated Time of ReadinessTime at which the ship will be ready to load, for instance when the crew has to clean the holds first.

FSW Frisian Shipyard WelgelegenNetherlands
FW Fresh Water Can designate either:1) Fresh water used by the ship for drinking, cooling system of various engine, showers, toilet.... Previously the amount was the biggest on departure in order to reach safely the port of destination. Nowadays most ships produce their own fresh water in an "evaporator" fed with sea water and using the heat of the engine. Often 25 tons a day is made, some 10 tons are used, so that 15 tons can be added to the stock with the result that the ship arrives with full tanks. This added weight is generally compensated by the consumption of FO and DO.2)Fresh Water as opposed to Sea Water regarding the density of the water supporting the ship. Normally the density of SW is 1.000, but in places like the Panama canal it can be 0.985 because it is warmer.

GA General Average.The cost incurred to bring the ship out of a dangerous position must be shared by all the
parties interested in the rescue, which means the cargo owners. These are then required to contribute to a General Average. This is quite easy with a bulker having one parcel of cargo, but a nightmare with a container vessel where thousands of parcels with different B/L are stowed in the containers.

Owner ShipownerThe formal owner of a ship. Although more and more he does not invest much money himself, but get a loan from financial institutions who trust his management. On some small ships the owner can be the captain. This was regularly the case in Greece, but recently the Dutch reverted to this system on some coasters as this is the best way to have a master highly motivated to defend the interests of the ship.

PDI Pre-Delivery InspectionValue added service by inspecting shipped goods when they leave the sea carrier.
Pilot Pilot Experienced local navigator who advise the master about the peculiarities of the port and its approaches. Practically the pilot directs himself the manoeuver of the vessel by giving steering
orders to the helmsman and engine orders to the ship mate. On some difficult waterways (Manchester, Scheldt-Brussels canals) the pilot or an assistant also steers directly the ship. The pilot is almost never responsible, except on Panama canal where his fault involves the liability of the canal authorities. Practically this is however limited by the numerous letters of "release of liability" if the ship has some handicaps such as a bad trim. When the liability of the canal is anyway involved, the serious delay caused by the investigation of any incident make that small damages to the ship are cheaper not to report.
PLIMSOLLMark PLIMSOLL MARK Mark carved and painted on both sides of the ship, at mid-length, showing the deepest draft at which the ship can be loaded. Imposed by Mr.Samuel PLIMSOLL in Britain in 1876.

RCDS Raster Chart Display SystemThe electronic chart display in use by the British Admiralty. Based on an image of the paper chart it is far inferior to the ECDIS, and is not accepted by SOLAS to ensure the seaworthiness of the vessel, so that a separate set of paper chart musts be carried and corrected.

RDF Radio Direction FinderNavigational instruments which was used to find out the direction of a radio broadcast. Although lacking some precision, it was very reliable when all the other means to fix the position were not available. Now it is mostly replaced by the GPS, only some coast station are using a kind of RDF working on VHF channel to locate small crafts. Once in the Windward passage between Cuba and Haiti I heard a small craft about to sink, calling with a portable VHF and which was totally unable to give a position to the closest USCG station, likely Guantanamo.

Roro Roll On / Roll offFerries with special doors through which large vehicles can be enter / leave the vessel. This type of ship is highly vulnerable if water submerge the main car deck, for instance after a
collision. Poor lashing of heavy trucks can also cause a dangerous list if some of them become looze in bad weather. Many roro capsized, usually drowning some or all crew members. BESMA which was in charge of the IFSMA working group on Roro still does not agree with the actual design of these ships.

STCW 95/98 Seafarer's Training, Certification and Watchkeeping Code 95IMO regulations on the minimum academic and training standards for deck and engine officers. These were necessary to fight certificates delivered by totally unqualified maritime schools. Together with the STCW the IMO publish a 'White List' of approved Nautical schools world wide. It remains that even those actual STCW standards are drastically low compared to those of three decades ago. With these STCW somebody can become captain after 24 months at sea only, thus less navigation time than some cadets of the sixties had when they became 4th mate not yet in charge of a watch. Even European nations are now joining the competition to lower the standards, assuming wrongly that anybody is able to sail or run a ship provided some minimum training has been offered. This goes against the increased complexity of the on board technology, against the variety and quantity of the dangerous and polluting goods transported, against the proliferation of rules which must be adhered to. Furthermore some training establsihment are urging the various national martime administration to reduce further the sailing time requirements by allowing 'virtual sailing time' to recruits who follow some special training or simulator courses!

WLTHC Water Line / Top of Hatch CoamingTo see if the load/discharge gear is large and high enough to reach the hatches. As the size of the ships increased faster than the size of the berth, this is often a problem. The ship can at
times be lowered by taking ballast, even if one hold if needed, but the depth can be a problem also. Giving a list can help in some cases.
