What is ship capacity plan? A plan of the spaces available for cargo, fuel, fresh water, water ballast, etc, and containing cubic or weight capacity lists for such spaces and a scale showing deadweight capacities at varying draughts and displacements.
What is a docking plan?
A docking plan is a document that is prepared for every ship during its preliminary design phase. All the information required to bring a ship to a dry dock are included in its docking plan.
How do you calculate deadweight?
To calculate the Deadweight tonnage figure, take the weight of a vessel that is not loaded with cargo and subtract that figure from the weight of the vessel loaded to the point where it is immersed to the maximum safe depth.
What do you mean by capacity planning?
Capacity planning is determining the ability of a production line, service department or function to meet a specified demand over a period of time. Inherent in this are actions required to adjust the capacity of the system to meet demand.
What is deadweight scale?
marine. A drawing used for estimating the additional draught or for determining the extra load that could be taken on board when a vessel is being loaded in water of density less than that of salt water.
What are the main docking and undocking operations?
Docking & Undocking
- Cast off lines and pull in fenders as the wind blows you away.
- When clear and safely away from the dock and other boats, shift to forward and depart at idle speed.
- Be careful to make sure you have been pushed safely away and that the stern will not hit the dock as you motor forward and turn.
How long does dry docking take?
The water is drained from the dry-dock (generally overnight) over the course of about eight to ten hours, depending on the size of the vessel.
Why is dry docking needed?
The main purpose of a Dry Dock is to expose the underwater parts for inspection, repair and maintenance. The ship to be repaired is hence manoeuvred into the lock and the gates are sealed post which all the sea water accumulated in the vessel is drained for better inspection and repairs.
How does deadweight work?
In a deadweight tester, the force is supplied by a mass in a gravitational field on top of a piston with a specific cross sectional area. … The pressure in the fluid is equal to the force exerted by the mass over cross sectional area of the piston.
What is deadweight loss example?
When goods are oversupplied, there is an economic loss. For example, a baker may make 100 loaves of bread but only sells 80. … This is a deadweight loss because the customer is willing and able to make an economic exchange, but is prevented from doing so because there is no supply.
What is the formula for calculating consumer surplus?
Calculating Consumer Surplus
While taking into consideration the demand and supply curvesDemand CurveThe demand curve is a line graph utilized in economics, that shows how many units of a good or service will be purchased at various prices, the formula for consumer surplus is CS = ½ (base) (height).
What is capacity planning with example?
On an assembly line in a car factory, for example, a painting robot might be able to paint 10,000 cars in a day. Considering this type of capacity is also important for workforce capacity planning; the workers on the assembly line are limited by the number of cars or parts a machine can process during a shift.
What are the types of capacity planning?
Types of Capacity Planning Strategies
- LEAD STRATEGY. The Lead Strategy involves an upfront investment in more capacity that is needed and is one of the most aggressive approaches used. …
- LAG STRATEGY. …
- MATCH STRATEGY. …
- DYNAMIC STRATEGY.
What are the steps in capacity planning?
How to develop an effective capacity planning process
- Select an appropriate capacity planning process owner.
- Identify the key resources to be measured.
- Measure the utilizations or performance of the resources.
- Compare utilizations to maximum capacities.
- Collect workload forecasts from developers and users.
What is displacement curve?
A displacement curve is one from which the displacement of the ship at any particular draft can be found, and vice versa. The draft scale is plotted on the vertical axis and the scale of displacements on a horizontal axis. As a general rule the largest possible scale should be used to ensure reasonable accuracy.
What is deadweight cargo capacity?
Deadweight Cargo Capacity (DWCC), or the net deadweight tonnage of a vessel, only expresses how much pure cargo can be loaded, without provisions, lubricant and fuels for the vessel.
Why does deadweight loss occur?
When supply and demand are out of equilibrium, creating a market inefficiency, a deadweight loss is created. Deadweight losses primarily arise from an inefficient allocation of resources, created by various interventions, such as price ceilings, price floors, monopolies, and taxes.
Does a boat move in idle?
Most boats have two 5 mph speeds. The first, with the throttle clicked just forward of neutral, is called “idling in gear” — so that the engine is turning at around 600 rpm. The second 5 mph speed is the one in which the engine is turning about 1,300 rpm.
What is dry docking a turtle?
DRY DOCKING TURTLES. There are illnesses and injuries involving the skin and shell that require maintaining aquatic or semi-aquatic turtles out of water until substantial healing has occurred; this is known as dry docking.
Which line should you secure first?
Secure the bow line. Put the boat in forward gear briefly, and slowly turn the steering wheel hard away from the dock—this will swing in the stern. Secure the stern line.
How much does dry docking cost?
An average sailboat costs between $800 – $1,800 per year. The price depends on location, season, and length of the boat. On average, a dock slip in the US costs anywhere between $12/ft per year to $240/ft per year, with an average of roughly $50/ft per year.
What is a dry dock period?
According to SOLAS regulation, every sea-going vessel has to undergo two dry docks within a period of 5 years. A ship in dry dock is a ship out of service. Dry dock is a complex process which is both expensive and time consuming. … Planning of dry docking starts several months before the scheduled date.
What is the largest dry dock in the world?
The largest roofed dry dock is at the German Meyer Werft Shipyard in Papenburg, Germany, it is 504 m long, 125 m wide and stands 75 m tall.
Where is the largest dry dock in the world?
Presently, Hyundai has the world’s largest dry-dock at Ulsan, South Korea which is 490m(1,600 feet) long, 115m across and 13.5m deep. A dry dock is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform.
