CLASS NOTATIONS (LR)- Lloyd’s Register (LR)
LR explained that the new class notations reflect the vessel's development and changing
service features, while retaining established notations.
LR maintains a Technical Committee, at present comprised of a maximum of 80 members, and
additionally an Offshore Technical Committee with specific responsibility for LR’s Rules for
Offshore Units, at present comprised of a maximum of 80 members.

- 100 This character figure will be assigned to all craft considered suitable for sea-going
service.
- A This character letter will be assigned to all craft which have been built or accepted
into class in accordance with LR's Rules and Regulations, and which are maintained
in good and efficient condition.
- 1 This character figure will be assigned to:
o Craft having on board, in good and efficient condition, anchoring and/or
mooring equipment in accordance with the Rules.

condition, anchoring and/or mooring equipment approved by the Committee as
suitable and sufficient for the particular service.
BULK CARRIER- This notation will be assigned to ships designed for the carriage of dry cargo in
bulk and built in accordance with the applicable requirements for carriage of cargoes of density of
at least 0.8 [t/m3 ].
3). ESP. This notation (Enhanced Survey Programme) will be assigned to oil tankers, combination
carriers, chemical tankers, bulk carriers and ore carriers.
4). CSR. This notation will be assigned to bulk carriers and double hull oil tankers compliant with
the IACS Common Structural Rules for Bulk Carriers and Oil Tankers (CSR).
For CSR bulk carriers, the ship’s longitudinal strength is to be evaluated by using the thickness of
structural members measured, renewed and reinforced, as appropriate, during the special Surveys
carried out after the ship reached 15 years of age (or during the special survey No.3, if this is
carried out before the ship reaches 15 years) in accordance with the criteria for longitudinal
strength of the ship’s hull girder for CSR bulk carriers specified in Ch.13 of CSR.
5). BC-A, {holds a, b, … may be empty} - This class will be assigned for bulk carriers designed
to carry dry bulk cargoes of cargo density 1,0 tonne/m3 and above with specified holds empty at
maximum draught.

Rules (CSR),
7). *IWS. This notation (In-water Survey) may be assigned to a ship where the applicable
requirements of LR's Rules and Regulations are complied with.
8). LI. This notation will be assigned where an approved loading instrument has been installed as
a classification requirement.
9). ShipRight ACS (B).
ShipRight( ). Where one or more of LR’s ShipRight procedures for the following have been
satisfactorily applied, then a notation showing the associated characters of the procedure(s) within
brackets will, at the Owner’s request, be entered in column 4 of the Register Book, preceded by
the word ShipRight, e.g. ShipRight(CM, SDA, FDA plus(25,NA)). The requirements pertaining
to these notations.
ACS() This ShipRight notation (Anti-Corrosion System) will be assigned when a specified area or
areas of the ship have been protected against corrosion in accordance with the relevant ShipRight
procedures. The ACS( ) notation with the extension of one or more of the following associated
supplementary characters shown in brackets, detailing the specified protected area or areas, may
be assigned;
B for protective coating system of water ballast tanks;
D for protective coating system of double-side skin spaces;
C for protective coating system of cargo oil tanks;
C* when corrosion resistant steel has been used in cargo oil tanks;
V for protective coating system of void spaces.
CM This ShipRight notation (Construction Monitoring), which complements the ShipRight SDA,
FDA, FDA plus() , FDA ICE, FDA SPR, and WDA notations, will be assigned when the controls
in construction tolerances detailed in the relevant ShipRight procedures have been applied and
verified. The ShipRight notation CM is mandatory upon application of any of the following ShipRight
notations: SDA, FDA, FDA plus(), FDA ICE, FDA SPR and WDA
The ShipRight Anti-Corrosion System notation ShipRight ACS (B) will be assigned when
protective coating system of water ballast tanks has been applied in accordance with the ShipRight
Procedure Anti-Corrosion System Notation.
Machinery: ✠LMC, UMS
1). ✠ LMC This notation will be assigned when the propelling and essential auxiliary machinery.
 the propelling arrangements for propellers, propulsion shafting and multiple input/output
gearboxes, steering systems, pressure vessels and electrical equipment for essential
systems have been constructed, installed and tested under LR’s Special Survey and are

 other items of machinery and gearing arrangements for propulsion and electrical power
generation and other auxiliary machinery for essential services are in compliance with LR
Rules and supplied with the Manufacturer’s certificate.
 the system arrangements of propelling and essential auxiliary machinery.

2). UMS This notation may be assigned when the arrangements are such that the ship can be
operated with the machinery spaces unattended. It denotes that the control engineering equipment
has been arranged, installed and tested in accordance with LR's Rules, or is equivalent thereto.
‘DESCRIPTIVE NOTES’:
Green Passport, Part Higher Tensile Steel,
ShipRight(BWMP(S+F),SERS,SCM)
In addition to any class notations, an appropriate descriptive note may be entered in column 6 of
the Register Book indicating the type of ship in greater detail than is contained in the class notation,
and/or providing additional information about the ship's design and construction. This descriptive
