(as defined in the following codes DNV 2.7-1, DNV 2.7-2, DNV 2.7-3)

Offshore Container: Portable unit up to 25 tonnes for repeated use in transport of goods or equipment, handled in open seas, to, from or between fixed and/or floating installations and ships.

Offshore Service Container: Offshore container built and equipped for a special service task, mainly for temporary installation. (Examples are, laboratories, workshops, stores, power plants, control stations.)

Offshore Freight Container: Offshore container built for transport of goods.

Installation/Vessel: This is used as a short term and may be a fixed offshore installation, a mobile offshore unit or a ship on which the container may be located.

Prototype: An equipment item, considered to be representative for the product to be approved, used for prototype testing. The prototype may either be manufactured specially for type testing or selected at random from a production series.

Classification Rules: Rules developed by the classification authority which are the basis of the classification certificate for the ship/offshore installation.

Statutory regulations: Regulations imposed by governmental authorities in the actual country where the equipment is used.

Recognized Standards: Standards found acceptable by Det Norske Veritas. Examples are ISO, IEC, CEN, CENELEC.

Reference Regulations, Standards etc: Abbreviated term for the classification rules, the statutory regulations and the recognised standards which are basis for the Certification Note.

Primary Structure: Load carrying and supporting frames and load carrying panels. Side and roof panels (including corrugated panels) are normally not considered to be part of the primary structure.

Secondary Structure: Parts which are not load carrying (for instance doors, plates in sides and roof).

Structural mass1, TS:
The mass in kilograms (kg) of structural components, including both primary and secondary structure.

Equipment mass, TE: The mass in kilograms (kg) of insulation and all permanently fitted or installed equipment, etc.

Fitted out mass1, TF: The mass in kilograms (kg) of the container ready for use, including both the structural mass and the equipment mass, i.e. TF = TS + TE

Payload, P: The maximum permissible mass in kilograms (kg) of cargo or loose equipment which may safely be transported by the container.

Rating, R: Maximum gross mass of the container and its cargo in kilograms (kg). The Rating consists of the mass of the structure, fitted equipment and the payload, i.e. R=TF + P

Recognized Test Institution for Ex Equipment: Private or governmental testing laboratories who have obtained an international status as independent and recognized testing institution for electrical equipment in explosive atmospheres.

Ex Certificate: A certificate issued by a recognised test institution as proof that the equipment has been tested and conforms to a specified standard.

Ex Equipment: Equipment having an Ex Certificate

Basic and Safety Systems: Fixed installed systems and equipment for electrical power supply distribution, ventilation, heating, gas detection, fire protection and lighting.

Utility Systems and Equipment:
Fixed installed or portable systems and equipment for use by the operators to perform a service. Examples are equipment for well logging, tool machines, power engines, office equipment, various testing equipment, etc.

Portable Equipment: Equipment not permanently installed and electrical equipment connected to power or control systems by the use of plugs or sockets.

Non-Combustible Material: Material which neither burns nor gives off flammable vapors in sufficient quantity for self-ignition when heated to approximately 750ºC, according to IMO Res.A.472 (XII) or an equivalent test procedure. Any other material is a "combustible material."

Low Flame Spread Surface Material: Material which will adequately restrict the spread of flames. Testing of low flame spread is to be based on IMO Res. A.653(16) or an equivalent test procedure.

Primary Deck Covering:
Deck covering which will not readily ignite or give rise to toxic or explosive hazards at elevated temperatures. Testing is to be based on IMO Res. A.214 (VII) or an equivalent test procedure.

Standard Fire Test: Test in which specimens of the relevant bulkheads or decks are exposed in a test furnace to temperatures corresponding approximately to a standard time-temperature curve. Reference is made to IMO Res. A:517(13) - "Recommendation and Fire Test Procedures for "A", "B" and "F" Class Divisions".

"A" and "B" Class Divisions: Divisions formed by bulkheads and decks which comply with the requirements in DNV Rules for Classification of Mobile Offshore Units, part 4, chapter 6.

Total Flooding Fire-Extinguishing System: A permanently fixed system designed for extinguishing in the complete volume of an enclosure.
