Maritime Terms, Abbreviations and Acronyms

Deck (OCIMF acronym)

Whereby a vessel discharges a quantity of slops to a dedicated slop receiving vessel within Port Limits or at a safe anchorage.

Whereby a vessel lands a quantity of items for the purpose of repair or storage ashore, or crew effects for personnel assigned to the vessel.

Diethanolamine. See ethanolamine

One leg of a move without a paying cargo load.Usually refers to repositioning an empty piece of equipment

A long ton of cargo that can be stowed in less than 40 cubic feet.

The standard measure of ships' carrying capacity. The trade usually abbreviates this term to speak simply of tankers "deadweight." This specification reports total weight, usually in long tons, of fresh water, stores, bunkers, and cargo a vessel can carry. For oil tankers, cargo averages 95 to 96 percent of the total.

Increasing production capacity of existing facilities through the modification of existing equipment to remove throughput restrictions. Debottlenecking generally increases capacity for a fraction of the cost of building new facilities.

Officer responsible for the safe navigation of a ship, as well as communications and safe loading, carriage and discharging of cargo and ship stability.

Products of a chemical or thermal break-down of a substance.

Place where loose or other non–containerized cargo is ungrouped for delivery.

The removal of dangerous goods from personnel and equipment to the extent necessary to prevent potential adverse health effects. Always avoid direct or indirect contact with dangerous goods; however, if contact occurs, personnel should be decontaminated as soon as possible. Since the methods used to decontaminate personnel and equipment differ from one chemical to another, contact the chemical manufacturer, through CANUTEC, CHEMTREC®, CHEM-TEL, SETIQ or CECOM to determine the appropriate procedure. Contaminated clothing and equipment should be removed after use and stored in a controlled area (hot zone) until cleanup procedures can be initiated. In some cases, protective clothing and equipment cannot be decontaminated and must be disposed of in a proper manner.

The "deep draft" of a vessel is measured from the surface of the water to the deepest part of the hull below the surface.

Definitely

The removal of natural oils from the skin by a fat-dissolving solvent

The product resulting from washing crude vegetable oil with water and/or steam for a specified period of time and then centrifuging the oil-and-water mixture to remove the phosphatides etc. The US Bureau of the Census requires crushers degumming crude soyabean oil to report the production of crude oil in terms of degummed weight.

All fats and oils contain small quantities of various non-glyceride entities. Included in this group are complex organo-phosphorus compounds referred to as phosphatides or more usually as gums. They are removed during processing by a variety of treatments collectively referred to as ""degumming"". The treatment applied varies but usually involves hydration with water, orthophosphoric acid, polybasic organic acids either singly or in combination, followed by centrifuging the precipitated material or by its adsorption on a bleaching earth or filter.

An organic chemical reaction in which a pair of hydrogen atoms are removed from a molecule.

Delivery

Delete

A coking unit (coker) which provides a drum where heated molecules crack and coke forms.

A condition in which there is a delay (usually hours or a few days) between acute exposure to a chemical and the subsequent development of lung injury.

Order to pick up goods at a named place and deliver them to a pier. Usually issued by exporter to trucker but may apply to a railroad, which completes delivery by land. Use is limited to a few major U.S. ports. Also known as shipping delivery order.

Demurrage (Quay Rent)

Demurrage and dispatch

Demurrage/Despatch money. (Under vessel chartering terms, the amount to be paid if the ship is loading/discharging slower/faster than foreseen.)

The cost of delaying a ship. Busy channels, occupied berths, commercial considerations, lack of shore tankage, pumping limitations, and a host of other eventualities related to how or where a charterer uses a vessel can prevent it from loading or unloading promptly. When they do, the ship's owner charges for a waiting time. Shall mean an agreed amount payable to the owner in respect of delay to the Vessel once the Laytime has expired, for which the owner is not responsible. Demurrage shall not be subject to exceptions which apply to Laytime unless specifically stated in the Charter Party.

(Quay Rent). Money paid by the shipper for the occupying port space beyond a specified _Free Time period.

The mass of a substance per unit volume. The density of a substance is usually compared to water, which has a density of 1. Substances which float on water have densities less than 1; substances which sink have densities greater than 1

A descripton of oil by some measurement of its volume to weight ratio. The industry usually relies on two expressions of oil's volume-weight relationship-specific gravity and API degrees. The larger a specific gravity number and the smaller an API number, the denser the oil.

Density is the mass of a unit volume of a substance. The density of an oil or fat is usually measured by determining its specific gravity.

Tank cleaning: Is the ratio of the mass of a volume of a product to the mass of an equal volume of freshwater (1.0). For a product with limited or no solubility in water the specific gravity indicates whether the product will float on water or sink.

Deodorisation is the removal of those trace components, present in all edible oils, which give rise to odours and flavours. Accomplished by the application of heat, steam and vacuum, deodorisation should be the final stage of treatment before packing or despatch.

Container freight station or a designated area where empty containers can be picked up or dropped off.

The depth to which a ship is immersed in water.

DEQ – Delivered Ex Quay (named port of delivery). This is similar to DES, but the passing of risk does not occur until the goods have been unloaded at the port of destination. Previous terms eliminated from Incoterms 2000

A Term of Sale which means the DDU term has been fulfilled when the goods have been available to the buyer on the quay (wharf) at the named port of destination, cleared for importa- tion. The seller has to bear all risks and costs including duties, taxes and other charges of delivering the goods thereto.

Derrick(s)

An inflammation of the skin

Despatch

DES – Delivered Ex Ship (named port of delivery). Where goods are delivered ex ship, the passing of risk does not occur until the ship has arrived at the named port of destination and the goods made available for unloading to the buyer. The seller pays the same freight and insurance costs as he would under a CIF arrangement. Unlike CFR and CIF terms, the seller has agreed to bear not just cost, but also Risk and Title up to the arrival of the vessel at the named port. Costs for unloading the goods and any duties, taxes, etc… are for the Buyer. A commonly used term in shipping bulk commodities, such as coal, grain, dry chemicals - - - and where the seller either owns or has chartered, their own vessel. Previous terms eliminated from Incoterms 2000

A Term of Sale where the seller fulfills his/her obligation to deliver when the goods have been made available to the buyer on board the ship, uncleared for import at the named port of destination. The seller has to bear all the costs and risks involved in bringing the goods to the named port destination.

A non propelled pontoon for the provision of desalination facilities

The design draft of a vessel is the maximum draft a vessel could potentially reach fully loaded whereas the operating draft is the typical draft that is employed since it is rare that vessels will sail at their maximum design draft.

Dispatch

DESPATCH ON ALL TIME SAVED shall mean that Despatch Money shall be payable for the time from the completion of loading or discharging to the expiry of the Laytime including periods excepted from the Laytime.

DESPATCH ON ALL WORKING TIME SAVED or ON ALL LAYTIME SAVED shall mean that Despatch Money shall be payable for the time from the completion of loading or discharging until the expiry of the Laytime excluding any periods excepted from the Laytime.

DESPATCH MONEY or DESPATCH shall mean an agreed amount payable by the owner if the Vessel completes loading or discharging before the Laytime has expired.

A Norwegian classification society which certifies seagoing vessels for compliance to standardized rules regarding construction and maintenance.

Diethylenetriamine. See ethyleneamines

A penalty charge against shippers or consignees for delaying carrier’s equipment beyond allowed time. Demurrage applies to cargo; detention applies to equipment. See Per Diem.

In simple terms a detergent is an aid to separation whether it be the separation of soil from a piece of cloth or the separation of olein from stearin in a fractionation plant. Alternatively classified as surface active agents, they work by lowering surface tension forces between two phases, in so doing allowing the more complete removal of the unwanted entity.

Chemically, oils and fats are quite stable, neutral substances. However, during storage and transport two types of deterioration can occur - a. Oxidation by atmospheric oxygen. This reaction is accelerated by high temperature, strong light and the presence of catalytic trace metals. b. Hydrolysis, resulting in splitting of the neutral fat to give free fatty acids. This is accelerated by the presence of water, by high temperature and by microbiological agents such as moulds and yeasts. Deterioration causes colour and flavour changes (rancidity) which eventually renders an oil unsuitable for food use.

DFDE propulsion is a relatively new technology for LNG carriers. Utilising electrical generators to drive the propeller, DFDE vessels are more fuel efficient and have lower carbon emissions compared to the conventional steam propelled vessels. The DFDE propulsion system uses either oil or gas, depending on the situation. It uses an electric motor like large cruise ships and submarines, not a steam turbine, which is the traditional propulsion system for LNG carriers. The DFDE propulsion system improves fuel efficiency, reacts quickly, and provides a smooth voyage.

Diameter

Refers to acids with two carboxyl groups, of which the most common have the general structure HOOC(CH2)nCOOH. They include (value of n in parenthesis): oxalic* (0), malonic* (1), succinic* (2), glutaric* (3), adipic* (4), suberic* (6), azelaic (7), sebacic (8), dodecanedioic* (10) and brassylic* (11). Systematic names such as nonanedioic acid indicate the presence of two carboxyl groups and the total number of carbon atoms in each molecule (in this case nine). Some of these are used in the production of polyesters and poly-amides. (*Azelaic, brassylic and sebacic are the only commercial dibasic acids from natural sources).

Diethylene glycol is a colorless liquid used as a solvent and in the manufacture of unsaturated polyester resins, polyurethanes and plasticizers.

Glycol ethers are manufactured from either propylene oxide or ethylene oxide reacted with an alcohol. Glycol ethers and glycol ethers acetates are both hydrophilic (soluble in water) and lipophilic (soluble in oils). They are excellent co-solvents, enabling non-miscible substances to be mixed with each other. They are mainly used as solvents, plasticizers and brake fluids, and in the composition of products such as cleaning and household products, glues, inks etc..

An amount added or deducted from base rate to make a rate to or from some other point or via an- other route.

The ester resulting from the chemical combination of glycerol and two fatty acids.

When an oil or fat is heated it expands and the expansion is called dilation. Dilation is the change in volume with varying temperature. The technique of observation is termed dilatometry. From the dilation observed on warming a solidified fat to a defined temperature, the solid's content at that temperature can be calculated. Dilatometry has been much used in the oils and fats industry for determining solid fat contents or indices of ingredients and blends in margarine and shortening manufacture. This technique has now been mainly replaced by solid fat content measurement using nuclear magnetic resonance spectrometry.

One member of the propylene glycols family, the most important of which is monopropylene glycol. Dipropylene glycol is used primarily as an industrial intermediate, but is also used as a substance in consumer products, and as an ingredient in pesticidal formulations. Uses of dipropylene glycol as a substance capitalize on its superior performance as a plasticizer as well as properties that permit dipropylene glycol to act as a functional ingredient of fluids.
