GLOSSARY
ADVANCED WASTEWATER PURIFICATION SYSTEMS (AWPS):
A biological treatment plant on board the vessel that treats the
wastewater generated on board to internationally established
standards.
ALTERNATIVE MARINE POWER: See Cold Ironing.
APPROVED CHEMICAL LIST: Company-specific list of
chemicals that have been approved for use on board by the
shoreside office.
BALLAST WATER: Fresh or saltwater stored in a vessel's tanks
to improve ship stability.
BALLAST WATER TREATMENT SYSTEM: System installed on
board a vessel to treat ballast water in order to prevent the
spread of non-native aquatic species.
BALTIC DISCHARGE STANDARDS: The Baltic Sea has been
recognized as a special area under MARPOL Annex IV and
prohibits the discharge of sewage effluent from passenger
ships operating in special areas, unless a passenger ship has in
operation an approved sewage treatment plant implementing
effluent standards and performance tests defined in the
2012 Guidelines on implementation of effluent standards and
performance tests for sewage treatment plants.

ISO 14001 STANDARD: A standard under the International
Organization for Standardization (ISO) which establishes
criteria for a company's Environmental Management System
(EMS) which maps out a framework that a company or
organization can follow.
MARPOL: International Convention on the Prevention of
Pollution from Ships. An international convention
regulating the disposal of bilge water, garbage, sewage, and
hazardous materials from ships and the emissions
generated from marine engines.
METRIC TONNE: Unit of weight equal to 1,000 kilograms
(2,205 lbs).
MULTISTAGE EVAPORATOR: System that produces fresh
water from seawater where the seawater is heated through
heat exchangers by steam produced by the boilers and heat
recovered from the exhaust gas of the engines.
NAUTICAL MILE (NM): Nautical Mile which is equal to 1.06
statute miles.

BERTHS: Double Occupancy per cabin (single occupancy per
studio cabin) even though many cabins can accommodate
three or more passengers.

OIL CONTENT METER: Part of the oily water separator system
on board a vessel that continuously monitors how much oil is
in the water.

BILGE WATER: Oily wastewater collected in machinery and
engine spaces.

OILY WATER SEPARATOR (OWS): Piece of equipment on
board a vessel that separates oil and water mixtures into
separate components.

BUNKERING: To provide fuel or water for a vessel.
COLD IRONING: The process of providing shoreside electrical
power to a ship at berth while its main and auxiliary engines
are turned off; also known as Alternative Marine Power.

PARTICULATE MATTER (PM): Mixture of organic and inorganic
particles that may be emitted from a vessel due to the burning
of fuel.

ENVIRONMENTAL MANAGEMENT SYSTEM (EMS): The part
of an organization's management system used to develop
and implement its environmental policy and manage its
environmental aspects.

PASSENGER CAPACITY DAY (PCD): Available Berths
multiplied by the number of cruise days for the period.

ENVIRONMENTAL OBJECTIVES: Overall environmental
priorities that an organization sets itself to achieve.
ENVIRONMENTAL POLICY: Overall intentions and direction of
an organization related to its environmental performance as
formally expressed by senior management.
ENVIRONMENTAL TARGET: Detailed performance
requirement, applicable to the organization or parts thereof,
that arises from the environmental objectives and that needs
to be set and met in order to achieve those objectives.
EXHAUST GAS CLEANING SYSTEM (EGCS): A system that
reduces the amount of sulfur oxide and particulate matter
emitted from the vessel by cleaning or scrubbing the fuel
before the emissions are released from the stack.
GROSS TONNAGE (GT): A measurement of total capacity of a
vessel expressed in volumetric tons of 100 cubic feet.
HAZARDOUS WASTE: Any waste material that is corrosive,
flammable, toxic, or reacts with other materials.
INTERNATIONAL CONVENTION FOR THE CONTROL AND
MANAGEMENT OF SHIPS' BALLAST WATER AND SEDIMENT:
Also known as the Ballast Water Convention, adopted in 2004,
this IMO convention establishes procedures for management
of ships' ballast and ballasting operations, in order to limit the
spread of non-native aquatic organisms.
INTERNATIONAL MARITIME ORGANIZATION (IMO): The
agency of the United Nations responsible for regulating shipping.
ISM CODE: The international code of standards for the
safe management and operation of ships, and for pollution
prevention. It was adopted by the IMO with the A.741(18)

50

resolution in May 1994 as a new chapter IX to the SOLAS
Convention. It entered into force for certain types of vessels on
1st July 1998 with others having to comply by 1st July 2002.

PASSENGER CRUISE PER DAY: The number of passengers
carried for the period multiplied by the number of days in their
respective cruises.
PERSONAL PROTECTIVE EQUIPMENT (PPE): Respiratory
protection, protective clothing, or other safety equipment that
ensures the safe handling of a chemical.
REVERSE OSMOSIS PLANTS: Plants that produce water from
seawater by utilizing high-pressure pumps and sophisticated
water filters and dosing (or treatment) components.
SAFETY MANAGEMENT SYSTEM: Systematic approach
to managing safety with established policies, procedures,
responsible parties, and organizational structure.
SHEARWATER: Long-winged seabird often found flying low
over the surface of the water far from land.
SHIPBOARD ENERGY EFFICIENCY MANAGEMENT PLAN
(SEEMP): Vessel-specific document and management tool
that outlines measures that can be implemented on board to
improve efficiency.
SOLID WASTE: Solid waste consists of aluminum and tin cans,
glass bottles, cardboard, office paper, food preparation and
table scraps, plastic bottles and containers, packaging, expired
light bulbs, paints and chemicals, refurbishment debris, and
medical waste.
SULFUR OXIDE: Vessel-related emissions as a result of fuel use.
TRIM: To distribute the load of a ship and assume a particular
position in the water so that the vessel sits well in the water
and/or to adjust with reference to the direction of the wind and
the course of the ship.
