ship and that by considering the ship’s speed and the rate of the effluent discharge, a conservative dilution factor (df) could be calculated as shown in (1.1). df = (width x draft x speed)/(discharge rate) (1.1) Using this formula, considering the beam and draft of three different large cruise ships, and an average discharge rate of 200 m. 3 ...
New building. The majority of new ships under construction are in the size of 120,000–140,000 m 3 (4,200,000–4,900,000 cu ft), but there are orders for ships with capacity up to 260,000 m 3 (9,200,000 cu ft). As of 2016, there were 451 LNG ships engaged in the deepsea movement of LNG.
The IMO adopted on 13 October 2006 the MEPC Resolution 157(55) which provides recommendation on standards for the rate of discharge of untreated sewage from ships, the text of which is set out in the Annex to the present document.
Self-unloaders are specialized ships equipped with onboard cargo-handling systems, enabling them to discharge without shore-based unloading equipment. Their rapid discharging rate, and reduced infrastructure and labour requirements, make this bulk cargo handling option an effective and competitive solution that helps keep costs down and minimize environmental impacts .
unstow or stow the cargo on the truck at a rate which enables the cargo to be moved as rapidly as may be accomplished by the Assignee of the Berth's, or his designee's, forklift machine and operator.

The following formulas are for calculating the rate at which a fluid will flow from a tank when the fluid level is maintained constant (h is constant). The discharge coefficient C d depends on the configuration of the outlet. Some typical values for discharge coefficient are shown below. Formulas for Calculating Flow Rate From a Vessel
A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would

Aframax is a medium-sized crude tanker with a dead weight tonnage (DWT) ranging between 80,000 and 120,000. The tanker derives its name from AFRA which stands for Average Freight Rate Assessment. AFRA system was created in 1954 by Shell Oil to standardise contract terms.

Tanker is proceeding en route. Instantaneous rate of discharge less than 30 litres per nautical mile. Total quantity discharge does not exceed 1/15,000 or 1/30,000 of the total cargo (depending on the age of the vessel) Oil discharge monitoring and control system and slop tank arrangement to be operating.
In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A.
The absorbent solution discharge rate is much lower than existing closed loop scrubbers and allows the Membrane Scrubber to store the absorbed effluent onboard for discharge ashore. If sodium hydroxide is used as the absorbent fluid, the effluent can be regenerated for reuse with a sulphuric acid by-product. ... The number of ships fitted with ...

A crane's discharge rate is limited by the bucket's capacity (from 6 to 40 tons) and by the speed at which the crane can take a load, deposit it at the terminal and return to take the ...
Cargo discharge plan ,draft survey & cargo calculation for bulk carriers The object of bulk carriers cargo discharge plan is to discharge cargo safely to reduce likelihood of ships structure overstressed during cargo work and to remain within the limitations as specified by the classification society .
Onboard procedures for loading LNG cargo - gas carrier guide LNG is liquefied natural gas, which is the very cold liquid form of natural gas.LNG carriers are generally specialised ships transporting LNG at its atmospheric pressure boiling point of approximately -162 degree C, depending on the cargo grade.LNG carriers were typically in the range 80-135,000 m3 up until 2006.
