CLIA ACC · Get comfortable with the vocabulary.

CLIA

Cruise Lines International Association, the global trade body representing cruise lines, travel agents, and industry partners; it sets member policies, publishes research, and runs training and events.

Related: Member Cruise Line, CLIA Events and Membership
Member Cruise Line

A cruise company that has joined CLIA and committed to its membership conditions, including safety, environmental, and passenger-protection obligations that go beyond bare legal minimums.

Related: CLIA, CLIA Member Maritime Policies
CLIA Member Maritime Policies

The binding rules CLIA members adopt collectively, covering areas such as environmental stewardship, health protocols, safety management, and responsible tourism conduct across the fleet.

Related: Member Cruise Line, Cruise Ship Environmental Officer
Flag State

The country where a cruise ship is registered; it has legal authority over the vessel and enforces international conventions such as SOLAS, MARPOL, and MLC through its own inspectors.

Related: Port State Control, MARPOL
Port State Control

Inspection of foreign-flagged ships by authorities at the ports they visit, verifying compliance with international safety, security, and pollution-prevention standards independently of the flag state.

Related: Flag State, MARPOL
MARPOL

The International Convention for the Prevention of Pollution from Ships; its annexes regulate oil, noxious liquids, sewage, garbage, and air emissions, including sulphur limits on fuel.

Related: EGCS, Shore Power
EGCS

Exhaust Gas Cleaning System, often called a scrubber; it removes sulphur oxides from engine exhaust so ships can meet emission limits while using higher-sulphur fuel, with washwater managed under discharge rules.

Related: MARPOL, LNG Fuel
LNG Fuel

Liquefied natural gas used as marine fuel; it cuts sulphur oxides and particulates sharply and reduces carbon dioxide compared with conventional fuel oil, though methane slip remains a concern.

Related: EGCS, Methane Slip
Methane Slip

Unburned methane escaping from engines, especially gas-fuelled ones; methane is a potent greenhouse gas, so slip reduces the climate benefit of LNG and drives interest in alternative fuels.

Related: LNG Fuel, Net Zero
Shore Power

Also called cold ironing: plugging a ship into the local electricity grid at berth so engines can shut down, cutting local air pollution and noise in port cities.

Related: MARPOL, Destination Stewardship
Net Zero

The target of balancing greenhouse gas emissions produced with those removed or offset; CLIA members have committed to net-zero carbon cruising by 2050, requiring new fuels and efficiency gains.

Related: Methane Slip, IMO
IMO

The International Maritime Organization, the United Nations agency that adopts global shipping rules on safety, pollution, and greenhouse gas reduction; cruise ships operate under its conventions.

Related: MARPOL, Flag State
SOLAS

The International Convention for the Safety of Life at Sea, the core global treaty governing ship construction, fire protection, life-saving equipment, and emergency procedures for passenger vessels.

Related: Muster Drill, Port State Control
Muster Drill

A mandatory safety briefing where passengers assemble at their assigned station to learn life-jacket use and emergency procedures, required before or shortly after departure.

Related: SOLAS, Safety Management System
Safety Management System

A structured set of documented procedures, risk assessments, and responsibilities that a ship operator uses to run vessels safely and respond consistently to incidents.

Related: SOLAS, Muster Drill
Vessel Sanitation Program

A public health inspection programme, run in the United States by the CDC, that scores cruise ships on water, food, and hygiene practices and publishes results for consumers.

Related: Norovirus, Public Health Inspection Score
Norovirus

A highly contagious virus causing vomiting and diarrhoea; cruise ships follow strict outbreak protocols including isolation, enhanced cleaning, and reporting to health authorities.

Related: Vessel Sanitation Program, Public Health Inspection Score
Public Health Inspection Score

A numeric rating from 0 to 100 given to a cruise ship after a sanitation inspection, with a score of 85 or above generally considered passing and results published publicly.

Related: Vessel Sanitation Program, Norovirus
Destination Stewardship

The practice of managing tourism so that host communities, cultures, and environments benefit and are not degraded, including spreading visitor flows and working with local stakeholders.

Related: Overtourism, Cruise Passenger Spending
Overtourism

When visitor numbers exceed what a destination can absorb comfortably, causing congestion, pressure on infrastructure, and resident opposition; cruise lines respond with scheduling and dispersal strategies.

Related: Destination Stewardship, Berth Allocation
Berth Allocation

The scheduling of which ship uses which dock or anchorage at which time; cruise lines and ports coordinate it to spread arrivals and reduce crowding in sensitive destinations.

Related: Overtourism, Tender Port
Tender Port

A port where the ship cannot dock and passengers are ferried ashore in small boats called tenders; this limits capacity and shapes shore-excursion planning and passenger flow.

Related: Berth Allocation, Shore Excursion
Shore Excursion

A guided activity sold to passengers for a port call, ranging from city tours to adventure and cultural experiences; often delivered by local operators contracted by the cruise line.

Related: Tender Port, Cruise Passenger Spending
Cruise Passenger Spending

Money passengers spend ashore on tours, food, shopping, and transport; a key economic contribution of cruising to destinations, measured through passenger surveys and local data.

Related: Shore Excursion, Economic Impact Study
Economic Impact Study

Research quantifying cruise tourism's contribution to a region through direct spending, indirect supplier activity, and employment, often produced for CLIA to support advocacy.

Related: Cruise Passenger Spending, Crew Spending
Crew Spending

Money cruise crew members spend in homeports and ports of call on food, transport, and goods; a smaller but locally meaningful part of cruise tourism's economic footprint.

Related: Economic Impact Study, Seafarer
Seafarer

A person employed to work aboard a ship; cruise seafarers include deck and engine officers, hotel staff, and entertainers, covered by international labour standards and training rules.

Related: MLC 2006, Crew Spending
MLC 2006

The Maritime Labour Convention, sometimes called the seafarers' bill of rights; it sets minimum standards on wages, hours, accommodation, food, and medical care on ships.

Related: Seafarer, Flag State
STCW

The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers; it sets minimum competence and certification requirements for ship officers and crew.

Related: Seafarer, SOLAS
Travel Advisor

A professional who sells and advises on cruise bookings; CLIA offers training, accreditation, and events to help advisors build product knowledge and industry credibility.

Related: CLIA Events and Membership, Berth Allocation

Homeport

The port where a cruise begins and ends, where passengers embark and disembark; homeports generate concentrated economic activity from provisioning, hotels, and air travel.

Related: Cruise Passenger Spending, Turnaround Port
Turnaround Port

A port where ships exchange full passenger loads, requiring efficient terminal operations for disembarkation, baggage, provisioning, and embarkation within a single day.

Related: Homeport, Cruise Passenger Spending

A voyage focused on exploration and education, often using smaller ships and Zodiac landings to reach remote regions such as polar, tropical, or wilderness destinations.

Related: IAATO, Polar Code
Regional Cruise Market

A geographic grouping of cruise demand and deployment, such as the Caribbean, Europe, or Asia; each has distinct source markets, seasonality, and itinerary patterns.

Related: Homeport, Source Market
