LR notation equivalent to DnV DYNPOS(AUTR)

This notation may be assigned when a ship is fitted with automatic main and automatic standby controls for position keeping and with position reference system(s) and environmental sensor(s). It denotes that the machinery and control engineering equipment has been arranged, installed and tested in accordance with LR’s Rules, or is equivalent thereto.

LR notation.

This notation will be assigned to existing ships in service that will be accepted or transferred into LR class when:

the propelling and essential auxiliary machinery, see Pt 1, Ch 2, 2.9 Application notes 2.9.1, have neither been constructed nor installed under LR’s Special Survey. But the existing machinery installation and arrangement have been tested and found to be acceptable to LR during the TOC survey.

LR notation equivalent to DnV Clean (design)

This notation will be assigned when the environmental protection arrangements are in accordance with the requirements of another recognised classification society and are essentially equivalent to Rule requirements and the ship is operated in accordance with the relevant requirements of the Rules.

LR notation equivalent to DnV BIS-notation

This notation (In-water Survey) may be assigned to a ship where the applicable requirements of LR’s Rules and Regulations are complied with, see Ch 3,4.3; Pt 3, Ch 1,5.2and 5.3; Pt 3, Ch 2,3.5; Pt 3, Ch 13,2.8 and Pt 5, Ch 6,3.12.

LR notation

Hazardous andnoxious liquids system. Assigned to Offshore Support Vessels complying with theaspects relevant to classification of the Codefor the transport and handling of hazardous and noxious liquid substances inbulk on offshore support vessels (OSV Chemical Code)

LR notation.

Designed  where fire protection and fire-fighting equipment is provided. Type 1, 2 or 3  signifies the capacity of the fire-fighting equipment. The total discharge  capacity of the monitors in m³/h is shown in brackets. ‘With water  spray’ signifies that a ship is provided with a water spray system which will  provide an effective cooling spray of water
