Question 1

TEU

Accepted Answer

Twenty-foot Equivalent Unit

Size of a standard 20' shipping container; 20 ft x 8 ft x 8 ft

Max gross mass: 52,910 lb (including selfweight)

Question 2

Port

Accepted Answer

An area on both land and water, whether on the sea or river, that provides facilities for shipping vessels to load & unload their cargo.

Typically man-made.

Question 3

Harbor (Harbour; Haven)

Accepted Answer

Tends to be a physical (naturally occurring) area where water meets land and results in a sheltered bay. 

Considered a 'safe space,' where ships can shelter from weather or where they are stored.

Question 4

Quay

Accepted Answer

Wharf or bank where ships & other vessels are loaded. Typically parallel to shoreline.

Structure built along the bank of a waterway (such as a river), especially one of solid masonry,  used as a landing for loading/unloading vessels.

Question 5

Terminal

Accepted Answer

Single man-made facility that may have several berths, that handles vessels and possibly more than one type of vessel or cargo.

Question 6

Dock

Accepted Answer

Is dug out and usually has gates so that the water level is kept up even when the tide is out, for mooring ships for cargo or passenger exchange, & sometimes repair. Access may only be at certain times of the tide.

Question 7

Dry Dock

Accepted Answer

Can have the water evacuated so the ship rests on the bottom for easy access to the hull.

Question 8

Wharf

Accepted Answer

Fixed platform, commonly on pilings, where ships are loaded/unloaded. Sometimes referred to as a quay, although they are supposedly different.

Typically parallel to shoreline

Question 9

Marina

Accepted Answer

Dock/basin for pleasure boats that has docks, moorings, supplies, and other facilities for small boats.
- Offers: water, fuel, repair, lifting/launching, supplies, electrical outlets, dry berthing
- Berths/quays = slips/fingers

Question 10

Seiches

Accepted Answer

Waves from storms with long period oscillations with periods usually > 30 sec. 

Can cause resonance period problems, and 1 to 3 min. periods cause problems for taut mooring lines.

Question 11

Seiching mitigation

Accepted Answer

- Adequate port/harbor basin area for dispersing wave energy.
- Beaches in suitable locations for absorption.
- Absorbing wharves/docks to dissipate wave agitation.

Question 12

DOF

Accepted Answer

Surge, sway, heave
Roll, pitch, yaw

Question 13

Capstan

Accepted Answer

Electric device for winding mooring lines

Question 14

Displacement Tonnage

Accepted Answer

Total WEIGHT of the volume of water a ship displaces

Question 15

Standard displacement tonnage

Accepted Answer

Displacement tonnage without the weight of fuel & potable water onboard

Question 16

Dead weight tonnage (DWT)

Accepted Answer

Sum of the WEIGHTS of cargo, fuel, freshwater, ballast water, provisions, passengers, & crew. Displacement tonnage minus lightweight tonnage.

Question 17

Lightweight tonnage

Accepted Answer

WEIGHT of the ship bare bones

Question 18

Gross tonnage

Accepted Answer

Total interior VOLUME of the vessel

Question 19

Net tonnage

Accepted Answer

Total CARGO SPACE interior VOLUME

Question 20

Gulf

Accepted Answer

Large body of water which can sometimes be considered enclosed by land

Question 21

Bay

Accepted Answer

Smaller than a gulf & with a wider entrance.

Question 22

Strait

Accepted Answer

Narrow water-body interconnecting 2 much larger water-bodies. Water flow in both directions, formed NATURALLY

Question 23

Channels

Accepted Answer

Larger than straits, more navigable

Question 24

Canals

Accepted Answer

Man-made straits

Question 25

Dolphins

Accepted Answer

Only found ashore. Independent platforms on the jetty with hooks or bollards to moor
