Scope The scope of this UR includes the following main activities: 1.1 Examination of the parts of the ship covered by classification rules and by applicable statutory regulations for hull construction, to obtain appropriate evidence that they have been built in compliance with the rules and regulations, taking account of the relevant approved drawings. 1.2 Appraisal of the manufacturing, construction, control and qualification procedures, including welding consumables, weld procedures, weld connections and assemblies, with indication of relevant approval tests. 1.3 Witnessing inspections and tests as required in the classification rules used for ship construction including materials, welding and assembling, specifying the items to be examined and/or tested and how (e.g. by hydrostatic, hose or leak testing, non destructive examination, verification of geometry) and by whom. 1.4 Appraisal of material and equipment used for ship construction and their inspection at works is not included in this UR. Details of requirements for hull and machinery steel forgings and castings and for normal and higher strength hull structural steel are given in W7, W8 and W11 respectively. Acceptance of these items is verified through the survey process carried out at the manufacturers works and the issuing of the appropriate certificates. 1.5 In addition to above, for Tankers and Bulk Carriers subject to SOLAS Chapter II-1 Part A-1 Regulation 3-10 (Goal-based ship construction standards for bulk carriers and oil tankers), see also Appendix 2 to this document.  Note: 1. This UR is to be uniformly implemented by IACS Societies on ships contracted for construction on or after 1 January 2008. 2. The contracted for construction date means the date on which the contract to build the vessel is signed between the prospective owner and the shipbuilder. For further details regarding the date of contract for construction, refer to IACS Procedural Requirement (PR) No. 29. 3. The changes introduced in Revision 2 of the UR are to be uniformly implemented by IACS Societies on ships contracted for construction (as defined in IACS PR 29) from 1 July 2010. 4. The changes introduced in Revision 3 of the UR are to be uniformly implemented by IACS Societies on ships contracted for construction (as defined in IACS PR 29) from 1 July 2016. 2.

The surveyors are to be qualified to be able to carry out the tasks and procedures are to be in place to ensure that their activities are monitored. Details are specified in PR6 and PR7. 5. Survey of the hull structure 5.1 Table 1 provides a list of surveyable items for the hull structure and coating covered by this UR, including: 5.1.1 description of the shipbuilding functions; 5.1.2 classification and statutory survey requirements; 5.1.3 survey method required for classification; 5.1.4 relevant IACS and statutory requirement references; 5.1.5 documentation to be available for the classification surveyor during construction. 5.1.5.1 The shipbuilder is to provide the classification surveyors access to documentation required by classification, this includes documentation retained by the shipbuilder or other third parties. 5.1.5.2 The list of documents approved or reviewed by the classification society for the specific new construction are as follows: a) plans and supporting documents b) examination and testing plans c) NDE plans d) welding consumable details e) welding procedure specifications f) welding plan or details g) welders qualification records h) NDE operators qualification records 5.1.6 Documents to be inserted into the ship construction file. Refer to paragraph 10 for details. 5.1.7 A list of specific activities which are relevant to the shipbuilding functions. This list is not exhaustive and can be modified to reflect the construction facilities or specific ship type. 5.2 Evidence is also to be made available, as required, by the shipbuilder, to the surveyor whilst the construction process proceeds to prove that the material and equipment supplied to the ship has been built or manufactured under survey relevant to the classification rules and statutory requirements. 6. Review of the construction facility* 6.1 The society is to familiarize themselves with the yard's production facilities, management processes, and Safety for consideration in complying with the requirements of Table 1 prior to any steelwork or construction taking place in the following circumstances: 6.1.1 where the society has none or no recent experience of the construction facilities typically after a one year lapse - or when significant new infrastructure has been added; 6.1.2 where there has been a significant management or personnel re-structuring having an impact on the ship construction process; 6.1.3 or where the shipbuilder contracts to construct a vessel of a different type or substantially different in design.  *Footnote: Reference is made to Appendix 1 Shipyard review record, as an example. 7. Newbuilding survey planning 7.1 Prior to commencement of surveys for any newbuilding project, the society is to discuss with the shipbuilder at a kick off meeting the items listed in Table 1. The purpose of the meeting is to review how the list of specific activities shown in Table 1 is to be addressed. The meeting is to take into account the shipbuilders construction facilities and ship type including the list of proposed subcontractors. A record of the meeting is to be made, based upon the contents of the Table 1 the Table can be used as the record with comments made into the appropriate column. If the society has nominated a surveyor for a specific newbuilding project then the surveyor is to attend the kick off meeting. The builder is to be asked to agree to undertake ad hoc investigations during construction where areas of concern arise and for the builder to agree to keep the classification society advised of the progress of any investigation. Whenever an investigation is undertaken, the builder is to be requested, in principle, to agree to suspend relevant construction activities if warranted by the severity of the problem. 7.2 The records are to take note of specific published Administration requirements and interpretations of statutory requirements. 7.3 The shipyard shall be requested to advise of any changes to the activities agreed at the kick off meeting and these are to be documented. E.g. if the shipbuilder chooses to use or change sub-contractors, or to incorporate any modifications necessitated by changes in production or inspection methods, rules and regulations, structural modifications, or in the event where increased inspection requirements are deemed necessary as a result of a substantial non-conformance or otherwise. 7.4 Shipbuilding quality standards for the hull structure during new construction are to be reviewed and agreed during the kick-off meeting. Structural fabrication is to be carried out in accordance with IACS Recommendation 47, Shipbuilding and Repair Quality Standard, or a recognized fabrication standard which has been accepted by the Classification Society prior to the commencement of fabrication/construction. The work is to be carried out in accordance with the Rules and under survey of the classification society. 7.5 The kick-off meeting may be attended by other parties as defined in PR3 (owner, administrations, etc.) subject to agreement by the shipbuilder. 7.6 In the event of series ship production consideration may be given to waiving the requirement for a kick off meeting for the second and subsequent ships provided any changes are documented as required in paragraph 7.1. 8. Examination and test plan for newbuilding activities 8.1 The shipbuilder is to provide plans of the items which are intended to be examined and tested. These plans need not be submitted for approval and examination at the time of the kick off meeting. They are to include: 8.1.1 proposals for the examination of completed steelwork - generally referred to as the block plan and are to include details of joining blocks together at the pre-erection and erection stages or at other relevant stages; 8.1.2 proposals for fit up examinations where necessary; 8.1.3 proposals for testing of the structure (leak and hydrostatic) as well as for all watertight and weathertight closing appliances; 8.1.4 proposals for non-destructive examination; 8.1.5 any other proposals specific to the ship type or to the statutory requirements. 8.2 The plans and any modifications to them are to be submitted to the surveyors in sufficient time to allow review before the relevant survey activity commences. 8.3 In addition to above, for Tankers and Bulk Carriers subject to SOLAS Chapter II-1 Part A-1 Regulation 3-10 see also Appendix 2 to this Unified Requirement. 9. Proof of the consistency of surveys 9.1 The classification society is to be able to provide evidence, e.g. through records, check lists, inspection and test records, etc. that its surveyors have complied with the requirements of the newbuilding survey planning and duly participated in the relevant activities shown in the shipbuilders examination and test plans. 10.
