17 [ PART II ] Rules for the construction and classification of steel ships, 2013 has been partly amended as follows:

18 [ PART II ] Chapter 1 General Paragraph 1.4 has been amended as follows: General (a) These test procedures are to confirm the watertightness of tanks and watertight boundaries, and the structural adequacy of tanks and which consist of the watertight subdivisions of ships. These procedures may also be applied to verify the weathertightness of structures and shipboard outfitting. The tightness of all tanks and tight water tight boundaries of ships during new construction and those relevant to major conversions or major repairs is to be confirmed by these test procedures prior to the delivery of the ship. new ships prior to delivery, and structures involved in, or affected by, major conversions or repairs is to be confirmed by these test procedures. (b) Major repair means a repair affecting structural integrity. (c) Gravity tank means a tank that is subject to vapor pressure not greater than 70 kpa Application (a) All gravity tanks and other boundaries required to be watertight or weathertight are to be tested in accordance with 1.4 and proven tight and structurally adequate as follows: (i) (ii) (iii) Gravity Tanks for their tightness and structural adequacy, Watertight Boundaries other than Tank Boundaries for their watertightness, and Weathertight Boundaries for their weathertightness. (b) The testing of the cargo containment systems of liquefied gas carriers is to be in accordance with standards deemed appropriate by the Society. (c) The Testingtesting of structures not listed in Table II 1-1 or 1-2 is to be specially considered Test Types of Tests and Definitions of Test (a) The following two types of test are specified in this requirement: (i) (ii) Structural ttest: A test to verify the structural adequacy of the tank construction of the tanks. This may be a hydrostatic test or, where the situation warrants, a hydropneumatic test. Leak ttest: A test to verify the tightness of a the boundary. Unless a specific test is indicated, this may be a hydrostatic / hydropneumatic test or an air test. Leak test with note [3] in Table II 1-1 includes A hose test as may be considered an acceptable medium of the test form of leak for certain boundaries, as indicated by [3] of Table II 1-1.

19 [ PART II ] (b) Definition The definition of each test type of test is as follows: (i) (ii) (iii) (iv) (v) (vi) (vii) Hydrostatic Test (Leak and Structural): A test by filling the wherein a space is filled with a liquid to a specified head. Hydropneumatic Test (Leak and Structural): A test combining a hydrostatic test and an air test. wherein the a space is partially filled with a liquid and air pressure applied on top of the liquid surface pressurized with air. Hose Test (Leak): A test to verify the tightness of the a joint by a jet of water with the joint visible from the opposite side. Air Test (Leak): A test to verify the tightness by means of air pressure differential and leak detection indicating solution. It includes tank air tests and joint air tests, such as a compressed air fillet weld tests and vacuum box tests. Compressed Air Fillet Weld Test (Leak): An air test of a fillet welded tee joint wherein with a leak indicating solution is applied on the fillet welds. Vacuum Box Test (Leak): A box over a joint with leak indicating solution applied on the fillet or butt welds. A vacuum is created inside the box to detect any leaks. Ultrasonic Test (Leak): A test to verify the tightness of a the sealing of closing devices such as hatch covers by means of ultrasound ultrasonic detection techniques. (viii) Penetration Test (Leak): A test to verify that no visual dye penetrant indications of potential continuous leakages exist in the boundaries of a compartment by the application means of low surface tension liquids (i.e. dye penetrant test) Test Procedures (a) General Tests are to be carried out in the presence of the Surveyor at a stage sufficiently close to the completion of the work with all hatches, doors, windows, etc., installed and all penetrations including pipe connections fitted, and before any ceiling and cement work is applied over the joints. Specific test requirements are given in (d) and Table II 1-1. For the timing of the application of coating and the provision of safe access to joints, see (e), (f) and Table II 1-3. (b) Structural test procedures (i) Type and time of test Where a structural test is specified in Table II 1-1 or Table II 1-2, a hydrostatic test in accordance with (d)(i) will be acceptable. Where practical limitations (strength of building berth, density of liquid, etc.) prevent the performance of a hydrostatic test, a hydropneumatic test in accordance with (d)(ii) may be accepted instead. as an equivalent method. Provided the results of a leak test are confirmed satisfactory, a A hydrostatic test for or hydropneumatic test for the confirmation of structural adequacy may be carried out while the vessel is afloat, provided the results of a leak test are confirmed to be satisfactory before the vessel is afloat.

20 [ PART II ] (ii) Testing Schedule for New Construction or Major Structural ConversionNumber of Structural Tests (1) A structural test is to be carried out for at least one tank of the same construction (i.e. tanks of the same structural design and configuration and same general workmanship as determined by the attending Surveyor) on each vessel provided all subsequent tanks are tested for leaks by an air test. However, where structural adequacy of a tank was verified by structural testing required in Table II 1-1, the subsequent vessels in the series (i.e. sister ships built in the same shipyard) may be exempted from such testing for other tanks which have the structural similarity to the tested tank, provided that the water-tightness in all boundaries of exempted tanks are verified by leak tests and thorough inspection. For sister ships built several years after the last ship of the series, such exemption may be reconsidered. In any case, structural testing is to be carried out for at least one tank for each vessel in order to verify structural fabrication adequacy. (2) For watertight boundaries of spaces other than tanks (excluding chain lockers), structural testing may be exempted, provided that the watertightness in all boundaries of exempted spaces are verified by leak tests and thorough inspection. (3) These subsequent tanks may require structural testing if found necessary after the structural testing of the first tank. (4) Tanks for structural test are to be selected so that all representative structural members are tested for the expected tension and compression. (1) The tank boundaries are to be tested from at least one side. The tanks for structural test are to be selected so that all representative structural members are tested for the expected tension and compression. (2) Structural tests are to be carried out for at least one tank of a group of tanks having structural similarity (i.e. same design conditions, alike structural configurations with only minor localised differences determined to be acceptable by the attending Surveyor) on each vessel provided all other tanks are tested for leaks by an air test. The acceptance of leak testing using an air test instead of a structural test does not apply to cargo space boundaries adjacent to other compartments in tankers and combination carriers or to the boundaries of tanks for segregated cargoes or pollutant cargoes in other types of ships. (3) Additional tanks may require structural testing if found necessary after the structural testing of the first tank. (4) Where the structural adequacy of the tanks of a vessel were verified by the structural testing required in Table II 1-1, subsequent vessels in the series (i.e. sister ships built from the same plans at the same shipyard) may be exempted from structural testing of tanks, provided that: - Water-tightness of boundaries of all tanks is verified by leak tests and thorough inspections are carried out. - Structural testing is carried out for at least one tank of each type among all tanks of each sister vessel. - Additional tanks may require structural testing if found necessary after the structural testing of the first tank or if deemed necessary by the attending Surveyor. For cargo space boundaries adjacent to other compartments in tankers and combination carriers or boundaries of tanks for segregated cargoes or pollutant cargoes in other types of ships, the provisions of paragraph 1.4.4(b)(ii)(2) shall apply in lieu of paragraph 1.4.4(b)(ii)(4).

21 [ PART II ] (5) Sister ships built (i.e. keel laid) two years or more after the delivery of the last ship of the series, may be tested in accordance with 1.4.4(b)(ii)(4) at the discretion of the Society, provided that: - general workmanship has been maintained (i.e. there has been no discontinuity of shipbuilding or significant changes in the construction methodology or technology at the yard, shipyard personnel are appropriately qualified and demonstrate an adequate level of workmanship as determined by the Society) and: - an enhanced NDT programme is implemented for the tanks not subject to structural tests. (6) For the watertight boundaries of spaces other than tanks structural testing may be exempted, provided that the water-tightness of boundaries of exempted spaces is verified by leak tests and inspections. Structural testing may not be exempt and the requirements for structural testing of tanks in 1.4.4(b)(ii)(1) to 1.4.4(b)(ii)(5) shall apply, for ballast holds, chain lockers and a representative cargo hold if intended for in-port ballasting. (c) Leak test procedures (i) (ii) For the leak test specified in Table II 1-1, a tank air tests, compressed air fillet weld tests, vacuum box tests in accordance with 1.4.4(d)(iv) through to 1.4.4(d)(vi), or their combination, will be acceptable. A Hhydrostatic or hydropneumatic test may also be accepted as the leak tests provided that 1.4.4(e), and 1.4.4(f) and 1.4.4(g) are complied with. A hhose tests will also be acceptable for the such locations as specified in Table II 1-1[3], in accordance with 1.4.4(d)(iii) with note [3]. A joint air test Air tests of joints may be carried out in the block stage provided that all work on the block that may affect the tightness of the a joint is completed before the test. See also 1.4.4(e)(i) for the application of final coatings and 1.4.4(f) for the safe access to the joints and their summary in Table II 1-3. (d) Details of Tests Test Methods (i) (ii) (iii) Hydrostatic Test Unless other liquid is approved, the hydrostatic tests are is to consist of filling the space by with fresh water or sea water, whichever is appropriate for testing of the space, to the level specified in Table II 1-1 or Table II 1-2. In cases where a tank for cargoes with higher density cargoes is to be tested with fresh water or sea water, the testing pressure height is to be specially considered. All external surfaces of the tested space are to be examined for structural distortion, bulging and buckling, other related damage and leaks. Hydropneumatic test A hhydropneumatic tests where approved, are is to be such that the test condition, in conjunction with the approved liquid level and supplemental air pressure, will simulate the actual loading as far as practicable. The requirements and recommendations for tank air tests in 1.4.4(d)(iv) will also apply to the hydropneumatic test. All external surfaces of the tested space are to be examined for structural distortion, bulging and buckling, other related damage and leaks. Hose test A hhose tests is are to be carried out with the pressure in the hose nozzle maintained at least at Pa during the test. The nozzle is to have a minimum inside diameter of 12 mm and be at a perpendicular distance to from the joint not exceeding 1.5 m. The water jet is to impinge directly upon the weld. Where a hose test is not practical because of possible damage to machinery, electrical equipment insulation or outfitting items, it may be replaced by a careful visual examination of welded connections, supported where necessary by means such as a dye penetrant test or ultrasonic leak test or an the equivalent.

22 [ PART II ] (iv) (v) (vi) (vii) Tank air test All boundary welds, erection joints and penetrations, including pipe connections, are to be examined in accordance with the approved procedure and under a stabilized pressure differential above atmospheric pressure not less than Pa, with a leak indication indicating solution such as soapy water/detergent or a proprietary brand applied. It is recommended that the air pressure in the tank be raised to and maintained at about Pa for approximately one hour, with a minimum number of personnel around the tank, before being lowered to the test pressure of Pa. A U-tube with a height sufficient to hold a head of water corresponding to the required test pressure is to be arranged. The cross sectional area of the U-tube is not to be less than that of the pipe supplying air to the tank. In addition to Instead of using a U-tube, a master gauge or other approved means to verify the two calibrated pressure is to gauges may be approved acceptable to verify required test pressure. A double inspection is to be made of tested welds. The first is to be immediately upon applying the leak indication solution; the second is to be after approximately four or five minutes in order to detect those smaller leaks which may take time to appear. Compressed air fillet weld test In this air test, compressed air is injected from one end of a fillet welded joint and the pressure verified at the other end of the joint by a pressure gauge on the opposite side. Pressure gauges are to be arranged so that an air pressure of at least Pa can be verified at each end of all passages within the portion being tested. Where a leak test of is required for fabrication involving partial penetration welding is required and the root face is sufficiently large (i.e. 6-8mm), the welds, a compressed air test is also to be applied in the same manner as for a to fillet weld where the root face is large, i.e., 6-8 mm. Vacuum box test A box (vacuum tester testing box) with air connections, gauges and an inspection window is placed over the joint with leak indicator indicating solution applied to the weld cap vicinity. The air within the box is removed by an ejector to create a vacuum of Pa inside the box. Ultrasonic test An arrangement of an ultrasonic echoes transmitter placed is to be arranged inside of a compartment and a receiver is to be arranged on the outside. The watertight/weathertight boundaries of the compartment are scanned with the receiver in order to detect an ultrasonic leak indication. A location where the sound is detectable by the receiver displays indicates a leakage in the sealing of the compartment. (viii) Penetration test (ix) A test of butt welds by applying a or other weld joints uses the application of a low surface tension liquid to at one side of a compartment boundary. When or structural arrangement. If no liquid is detected on the opposite side of the boundaryies after the expiration of a definited period of time, the verification of this indicates tightness of the compartments boundary can boundaries. In certain cases, a developer solution may be assumed painted or sprayed on the other side of the weld to aid leak detection. Other test Other methods of testing may be considered by each the ssociety upon submission of full particulars prior to the commencement of the testing.

23 [ PART II ] (e) Application of coating (i) (ii) Final coating For butt joints welded by an automatic process, the final coating may be applied any time before the completion of the a leak test of the spaces bounded by the joints, provided that the welds have been carefully inspected visually to the satisfaction of the Surveyor. The Surveyor reserves the right to require a leak test prior to the application of the final coating over automatic erection butt welds. For all other joints, the final coating is to be applied after the completion of the leak test of the joint. See also Table II 1-3. Temporary coating Any temporary coating which may conceal defects or leaks is to be applied at a the time as specified for the final coating. This requirement does not apply to shop primer. (f) Safe access to joints For leak tests, a safe access to all joints under examination is to be provided. See also Table II 1-3. (g) Any other recognized method may be accepted to the satisfaction of the Surveyor.

27 [ PART II ] Note : [1] Structural test is to be carried out for at least one tank of the same construction (i.e., same design and same workmanship) on each vessel provided all subsequent tanks are tested for leaks by an air test. However, where structural adequacy of a tank was verified by structural testing, the subsequent vessels in the series (i.e., sister ships built in the same shipyard) may be exempted from such testing for other tanks which have the structural similarity to the tested tank, provided that the water-tightness in all boundaries of exempted tanks are verified by leak tests and thorough inspection is carried out. In any case, structural testing is to be carried out for at least one tank for each vessel in order to verify structural fabrication adequacy. (See 1.4.4(b)(ii)(1)) Refer to 1.4.4(b)(ii) [2] The Toptop of a tank is the deck forming the top of the tank, excluding any hatchways. [3] Hose Test may also be considered as a medium of the test. See 1.4.3(b). [4] Including tanks arranged in accordance with the provisions of SOLAS regulation II-1/9.4.

[6] Where water tightness of watertight door has not been confirmed by prototype test, testing by filling watertight spaces with water is to be carried out. See SOLAS regulation II-1/16.2 and MSC/Circ [7] Where a hose test is not practicable, other testing methods listed in 1.4.4(d)(vii) through 1.4.4(d)(ix) may be applicable subject to adequacy of such testing methods being verified. See SOLAS regulation II-1/11.1. [87] As an alternative to the hose testing, other testing methods listed in 1.4.4(d)(vii) through 1.4.4(d)(ix) may be applicable subject to the adequacy of such testing methods being verified. See SOLAS regulation II-1/11.1. For watertight bulkheads (item 11.1) alternatives to the hose testing may only be used where a hose test is not practicable. [8] A Leak and structural test, see 1.4.4(b)(ii) is to be carried out for a representative cargo hold if intended for in-port ballasting. The filling level requirement for testing cargo holds intended for in-port ballasting is to be the maximum loading that will occur in-port as indicated in the loading manual. [9] Structural test may be waived where demonstrated to be impracticable to the satisfaction of the Society.

30 [ PART II ] Chapter 25 Equipment Paragraph has been added as follows: Equipment for Offshore Service Units The requirements herein are intended for temporary mooring of a unit within a harbor or other areas of sheltered water. The Equipment Number equation is based on 2.5 m/s current, 25 m/s wind and a scope of 6 through 10, the scope being the ratio of length of chain paid out to the water depth. Anchors and chains are to be in accordance with Table II 25-1 and the numbers, mass and sizes of these are to be regulated by the equipment number (EN) obtained from the following equation: Equipment Number = hk(δ/h)2/3 + mσqcschaf + nσqcschap where k = 1.0 m = 2 n = 0.1 h = number of hulls or pontoons of the unit Δ = molded displacement of the unit in metric tons, excluding appendages, taken at the transit draft ΣqCsChAf = total frontal area exposed to the wind in m 2 at the transit draft q = 1.0 for hull, superstructure and deck houses = 0.3 for other wind areas Cs = shape coefficient, as shown in Table III 13-1 of Part III of the Rules Ch = height coefficient as shown in Table III 13-2 of Part III of the Rules Af = frontal projected area of each major element exposed to the wind, in m 2, including columns, upper structure, deck members, superstructures and deck houses, trusses, large cranes, derrick substructure and drilling derrick as well as the portion of the hull above the transit waterline, as applicable to the type of unit. Wind shielding in accordance with acceptable methods may be considered. ΣqCsChAp = total profile area exposed to the wind in m 2 at the transit draft Ap = profile area of each major element exposed to the wind, in m 2, including columns, upper structure, deck members, superstructure and deck houses, trusses, large cranes, derrick substructure and drilling derrick as well as the portion of the hull above the transit waterline, as applicable to the type of unit. Wind shielding in accordance with acceptable methods may be considered.

31 [ PART II ] In calculating the wind areas, the following conditions are to be considered: (a) Tiers of superstructures or deck houses having a breadth at any point no greater than 0.25B, where B is the molded breadth of the unit, may be excluded, provided that their projected area is less than 1/100 of the total projected area of the unit. (b) Screens and bulwarks more than 1.5 m in height are to be included. (c) In the case of units with columns, the projected areas of all columns are to be included (i.e. no shielding allowance is to be taken). However, a shape coefficient of 0.5 may be used for the column s cylindrical surfaces. (d) The block projected area of a clustering of deck houses may be used in lieu of calculating each individual area. In this case, the shape coefficient is to be taken as 1.1. (e) Large isolated structures such as cranes and derricks are to be calculated individually using the appropriate shape coefficients from Table III 13-1 of Part III of the Rules. (f) Small isolated structures with a projected area less than 1/100 of the total projected area of the unit may be excluded. (g) Open truss work commonly used for derrick towers, booms and certain types of masts may be approximated by taking 30% of the projected block areas of both the front and back sides (i.e., 60% of the projected block area of one side for double sided truss work). The shape coefficient is to be taken in accordance with Table III 13-1 of Part III of the Rules. Note: Lateral wind areas (larger side) of open truss work in dual derrick towers may be approximated by taking 25% of the projected block areas of both the front and back sides. In all open truss derrick towers, the wind areas in the V-door levels may be approximated by taking 20% of the projected block areas of both the front and back sides. Alternatively, the effective wind areas may be calculated by using the results of wind tunnel tests or recognized computational fluid dynamics (CFD) software with a representative model of the unit or designated item, including all the elements that can contribute to the wind resistance, and subjected to the wind conditions equivalent to 25 m/s or over. Documentation and calculations demonstrating the effective wind areas by the alternative methodology are to be submitted for review. Note: When the effective wind areas are obtained from the results of wind tests or CFD analysis and the percentage of wind area related to hull, superstructures and deckhouses cannot be estimated, a value not less than 75% (frontal) and 50% (profile) of the resulting effective wind areas may be used in the equipment numeral equation in lieu of the total frontal area and the total profile area, respectively.
