FERRY

• A FERRY IS A BOAT OR SHIP USED TO CARRY PASSENGERS AND SOMETIMES VEHICLES & CARGO AS WELL ACROSS THE WATER.

• Other names water bus or water taxi.

• Depend on Length of route, passenger or vehicle capacity, speed requirement and water condition.

Types of ferries

1. Double-ended

2. Hydrofoil

3. Hovercraft

4. Catamaran

5. Ro-ro

6. Cruiseferry

Double-Ended

Double-ended ferries have interchangeable bows and stern, allowing them to shuttle back and forth between two terminal without having to turn around

Hydrofoil

• It have advantage of higher cruising speed, succeeding hovercraft on some English channel route.

Hovercraft

• Hovercraft are developed in 1960s to carry cars.

• The largest was massive SR.N4 which carried cars in centre section with ramps at bow and stern between England and france.

• It was superseded by catamarans which are nearly as fast and are less affected by sea

Catamaran

It is normally associated with high speed ferry service, water jetpowered vessels

Ro-ro

• Roll-on/ Roll-off ferry are large, conventional ferries named for ease by which vehicle can board and leave

Cruiseferry

• A ship that combines features of a cruise ship with a Ro-Ro ferry

Turntable ferry

• It Allow vehicle to load from side

• The platform can be turned

• When loading platform is turned sideways to allow sideways loading of vehicle

Pontoon:Carry vehicles across rivers and lakes

Transfer Bridge / Ferry Slip

• A ferry slip is a specialized docking facility that receives a ferry boator train ferry,

• A similar structure called a barge slip receives a barge or car float thatis used to carry wheeled vehicles across a body of water,

• In other cases, the ramp is installed at the ferry slip and is called alinkspan or apron,

• Such ramp is adjustable to accommodate varying water heights andferry loadings and to move it out of the way during approach and exit.

FLOATING LANDING STAGES

• It is a platform which is used for the purpose of loading and unloadingpeople and goods from ocean going vessels, including boats and shipsof all shapes, style and sizes

• In areas with shallow water or limited space, the landing stage may bedesigned for use with tenders and ship’s boats

• stage may also house customs warehouses, immigration offices, andother government facilities

• They can also house things like tourist information centers

TRANSIT SHEDS

These are covered temporary structures located adjacent or onthe pier or wharf for temporary storage of cargo.

PURPOSE:-

• To protect the cargo from rain, sun, cold, dust etc,

• To protect the cargo from damage or theft,

• To separate and stack the individual consignments,

• Storage of goods discharged from vessels and awaitingclearance through customs and distribution towarehouses,

• Storage of goods arriving by land and awaiting export.

WAREHOUSE

• Permanent structure, usually provided on shore or directly behindtransit sheds for relatively long term storage of cargo,

• Made of RCC, timber framing and siding with roofing covering ofappropriate roofing materials,

• It should be light in weight, fire resisting,

• It should be adjacent to pier or wharves to be served,

• Road and rail services are provided at the back and front of thewarehouses with roads at the end.

Apron

• The open space left immediately in front of a berth is known as apron,

• It is required for loading and unloading of cargo from vessels,

• The apron is utilized for the installation of railway tracks and variousother mechanical contrivances such as road trucks, cranes etc. useapron for the efficient discharge of the cargo

• The width of apron depends upon the factors like cost of construction,operation involved, needs of handling the cargo etc

• The width of apron should be such that it results in minimum traveltime of cargo to and from the ship and the transit shed.

• Width=10m for ports with light traffic to 25m for heavy traffic
