General Requirements

1 Testing and Inspection

1.1 General

All materials subject to test and inspection, intended for use in the construction of hulls and equipment of

vessels classed or proposed for classification, are to be to the satisfaction of the Surveyor and in

accordance with the following requirements or their equivalent. Materials, test specimens and mechanical

testing procedures having characteristics differing from those prescribed herein may be approved upon

application, due regard being given to established practices in the country in which the material is

produced and the purpose for which the material is intended, such as the parts for which it is to be used, the

type of vessel and intended service, and the nature of the construction of the vessel.

1.2 Manufacturer Approval (2003)

1.2.1 (2019)

All products for hull construction are to be manufactured at steel works approved by ABS for the

type and grade of steel contemplated. The suitability of the products for welding and assumed

forming is to be demonstrated during the initial approval test at the steel works. Approval of the

steel works for rolled products is to be in accordance with Part 2, Appendix 4. Refer to 2-1-1/1.11

for structural pipe. Structural pipe for hull construction refers to stanchions, pillars and truss

members integral to the hull.

1.2.2 (2006)

It is the manufacturer’s responsibility to assure that effective procedures and production controls

are implemented during the production, and that the manufacturing specifications are adhered to.

Should any deviation from the procedures and controls occur that could produce an inferior

product, the manufacturer is to carry out a thorough investigation to determine the cause of the

mishap and establish countermeasures to prevent its recurrence. The complete investigation report

is to be submitted to the Surveyor. ABS reserves the right to request a closer survey until the cause

is resolved to the satisfaction of the Surveyor. Each affected piece is to be tested to the satisfaction

of the attending Surveyor prior to distribution from the steel works. In addition, the frequency of

testing for subsequent products may be increased to gain confidence in the quality.

1.2.3

Where the steel is not produced at the rolling mill, the procedures in 2-1-1/7.3 are to be followed.

3 Surface Quality (1 July 2018)

3.1 General

The steel is to be free from cracks, injurious surface flaws, injurious laminations and similar defects

prejudicial to the use of the material for the intended application.

The finished material is to have a surface quality in accordance with a recognized standard such as EN

10163 Parts 1 (General), 2 (Plates), or ASTM A6 or an equivalent standard accepted by ABS, unless

otherwise specified in this Section. In case there is conflict between the requirements, the more stringent

requirements are to be followed.

3.3 Manufacturer Responsibility

The responsibility for meeting the surface quality requirements rests with the manufacturer of the material,

who is to take the necessary manufacturing precautions and is to inspect the products prior to delivery. At

that stage, however, rolling or heat treatment scale may conceal surface discontinuities and defects. If,

during the subsequent descaling or working operations, the material is found to be defective, ABS may

require materials to be repaired or rejected.

3.3.1

The surface quality inspection method shall be in accordance with recognized national or

international standard agreed between purchaser and manufacturer, accepted by ABS.

3.3.2

If agreed by the manufacturer and purchaser, steel may be ordered with improved surface quality

over and above these requirements.

3.5 Acceptance Criteria

3.5.1 Imperfections

Imperfections, for example pitting, rolled-in scale, indentations, roll marks, scratches and grooves,

regarded as being inherent to the manufacturing process, are permissible irrespective of their

number, provided the maximum permissible limits of Class A of EN 10163-2 or limits specified in

a recognized equivalent standard accepted by ABS, are not exceeded and the remaining plate or

wide flat thickness remains within the average allowable minus thickness tolerances specified in

2-1-1/15. Total affected area with imperfections not exceeding the specified limits are not to

exceed 15% of the total surface on each side.

3.5.2 Defects

Affected areas with imperfections with a depth exceeding the limits of Class A of EN10163-2 or

the maximum permissible limits specified in a recognized equivalent standard accepted by ABS,

shall be repaired irrespective of their number.

Cracks, injurious surface flaws, shells (over lapping material with non-metallic inclusion), sand

patches, laminations and sharp edged seams (elongated defects) visually evident on surface and/or

edge of plate are considered defects, which would impair the end use of the product and which

required rejection or repair, irrespective of their size and number.

3.7 Repair

3.7.1 Grinding Repair

Unless otherwise agreed, grinding may be applied provided all the conditions below are adhered

to:

i) The nominal product thickness will not be reduced by more than 7% or 3 mm (0.12 in.),

whichever is the less.

Part 2 Materials and Welding

Chapter 1 Materials for Hull Construction

Section 1 General Requirements 2-1-1

ABS RULES FOR MATERIALS AND WELDING • 2022 11

ii) Each single ground area below the minimum thickness does not exceed 0.25 m

(2.7 ft

iii) All ground areas below the minimum thickness do not exceed 2% of the total surface in

question.

iv) Ground areas lying in a distance less than their average width to each other are to be

regarded as one single area.

v) Ground areas lying opposite each other on both surface shall not decrease the product

thickness by values exceeding the limits as stated under i.

Defects or unacceptable imperfections are to be completely removed by grinding and the

remaining plate or wide flat thickness shall remain within the average allowable thickness

tolerance specified in 2-1-1/15. The ground areas are to have a smooth transition to the

surrounding surface of the product. Complete elimination of the defect can be verified by visual

inspection, Magnetic particle (MT) or liquid penetrant (LT) testing. Note: The NDE technique

initially used to detect a defect is to be applied after grinding to verify defect removal. NDE

operators are to be qualified to the satisfaction of the attending Surveyor.

NDE can be carried out in accordance with the manufacturer’s conformance standard, provided

the conformance standard is submitted to ABS Materials for acceptance.

3.7.2 Welding Repair

Weld repair procedures and the method for repair are to be reported and be approved by ABS. To

confirm defects have been removed prior to weld repair, MP or LP may be required. Repair of

defects such as unacceptable imperfections, cracks, shells or seams shall be followed by MP or LP

testing.

Local defects which cannot be repaired by grinding as stated in 2-1-1/3.7.1 may be repaired by

welding with the agreement of ABS subject to the following conditions:

i) Any single welded area shall not exceed 0.125 m

(1.35 ft

) and the sum of all areas shall

not exceed 2% of the surface side in question.

ii) The distance between two welded areas shall not be less than their average width.

iii) The weld preparation shall not reduce the thickness of the product below 80% of the

nominal thickness. For occasional defects with depths exceeding the 80% limit, special

consideration at the Surveyor’s discretion will be necessary.

iv) If weld repair depth exceeds 3 mm, UT may be requested by ABS. If required, UT shall

be carried out in accordance with an approved procedure.

v) The repair shall be carried out by qualified welders using an approved procedure for the

appropriate steel grade. The electrodes shall be of low hydrogen type and shall be dried in

accordance with the manufacturer’s requirements and protected against re-humidification

before and during welding.
