INSPECTIONS, TESTS AND TRIALS 1. Following inspections/trials/tests would be conducted:-

(a) In Line Inspections (ILI) (b) Technical Tests and Trials (c) Pre-Dispatch Inspections (PDI) (d) Joint Receipt Inspections (JRI)

2. In Line Inspections. This would be carried out by the Naval Overseer at the builders premises during construction of the boats and involve scrutiny of the methodology of construction, raw materials and dimensional checks. 3. Technical Tests and Trials 3.1 Builders Responsibilities

3.1.1 The builder shall prepare and forward to the Naval Inspecting Authority, a programme of trials before commencement of trials duly vetted by Class.

3.1.2 The builder shall arrange for the attendance of representatives of their subcontractors during the trials. However, the Naval Overseers would be positioned and maintained by the Navy.

3.1.3 The Builder shall lift or slip each boat after completion of all tests to enable examination of underwater hull and fittings.

3.1.4 The Builder shall be responsible for the provision of any spare parts, tools, equipment, etc. required during trials. Builder shall be responsible for replacement of any item/equipment damaged or found to be defective during trials without prejudice to any of the spare gear provided. The Builder shall also make good at his own expense, all defects found in the construction, fittings, machinery and electrical installations before the boat is accepted.

3.2 Sequence of Tests & Trials Unless prior IHQ-MOD(Navy) approval is obtained, all tests and trials shall be carried out in the same sequence as they are described in the following paragraphs and in a continuous manner. Wherever possible, the Inclining Experiment shall immediately follow the Weighing Test. 3.3 Swamp Test This test shall be carried out only for the first boat of the particular contract. The boat is to be fitted with sufficient buoyancy material to enable the satisfactory swamp test to be undertaken. The quantity and arrangement of buoyancy proposed shall be forwarded to IHQ MoD (Navy) for




REV. No 4



approval. The object of this test is to ensure that the boat will remain afloat, stable and upright at normal trim and with at least 10% reserve of buoyancy after it has been filled with water. This ensures that there is a positive freeboard all round the boat when it is swamped, thus enabling the water to be pumped or baled out. 3.3.1 Preparation 3.3.1.1 The boat shall be as complete as possible, but any

structure/equipment that would suffer from immersion in water during test shall not be fitted but represented by ballast of impervious material eg. Cast iron pigs. This ballast shall be arranged to represent the combined weight and CG of the missing items in the boat.

3.3.1.2 The total weight to be compensated is made up of the weights

in air of items which would be above water with gunwales completely awash, and the weights in water of items which would be below water in this condition.

3.3.1.3 The compensating ballast will usually be immersed during

the test and allowance must be made for its affective loss of weight in water. Suitable density corrections shall be made depending on the water used to swamp the boat.

3.3.1.4 The weight of an item in water can be readily determined if

the item is regularly shaped. If it is not, a reasonable estimate of its watertight volume should be made, based on measurement of its principal dimension from which an approximate loss of weight in water can be found.

3.3.1.5 The boat shall be weighed just prior to the swamp test, and

the weight recorded. The compensating ballast should then be placed onbroad and arranged so that its CG is in the correct position, as calculated.

3.3.2 Test 3.3.2.1 The ballasted boat shall be placed in a sufficient depth of

water allowing it to sink to the gunwales without grounding. It shall be held on slack lines, and if the water is deep, precautions shall be taken to prevent the boat from sinking completely.

3.3.2.2 The drafts forward and aft, and the density of water shall be

recorded prior to swamping.




REV. No 4



3.3.2.3 The boat shall then be swamped until the gunwales are awash, drafts recorded. Finally, the ballast shall be added progressively until it is equal to 10% of the total weight of the boat and drafts recorded. The boats should maintain positive freeboard in this condition.

3.3.3 Report of Swamp Test As soon as possible, after the test, the boat

builder shall forward the following detailed report to IHQ-MoD (Navy) through the Naval Overseer:-

(a) The weight of boat prepared for swamp test (without compensating

ballast). (b) Calculation of weights of compensating ballast and position of its

CG. (c) Draughts of boat just prior to test (with compensating ballast

aboard). (d) Draughts of boat with addition of 10% of weight of boat as ballast. (e) SG of water in which swamp test was conducted. (f) SG of water used to swamp the boat. (g) An amount of total buoyancy provided in the boat by means of

buoyancy tanks in cubic metres/feet. 3.3.4 If during the course of the test, serious doubts arise as to the

adequacy of boat's buoyancy or stability, the matter shall be reported immediately to IHQ-MoD (Navy) . If when swamped, the boat has excessive heel or trim, or is unstable, does not have at least 10% reserve of buoyancy, the matter shall be investigated and corrective measures taken. The swamp test shall be repeated until satisfactory results are achieved.

3.4 Drop Test First boat of the order shall be subjected to this test. The completed boat with compensating ballast for full complement, machinery and fuel shall be drop tested, as per the requirements of SOLAS 1983, by dropping the boat in water from a height of 3 meters. After the drop test the boat shall not suffer from any residual deformation/defect. 3.5 Impact Test. First boat of the order shall be subjected to this test. The completed boat with compensating ballast for full complement, machinery and fuel shall be subjected to an impact test as per the requirements of SOLAS 1983. For this test, the boat shall be subjected to a lateral impact against a steel impact. The boat shall not suffer from any residual deformation/defects. 3.6 Deflection Test First boat of the order shall be subjected to this test. The completed boat with compensating ballast for full complement, machinery and fuel shall be subjected to a deflection test as per the requirements of SOLAS 1983. For this test, the boat shall be supported at the ends and a load equal to




REV. No 4



twice the mass of the boat shall be placed at the centre. The boat shall not have any residual deflection on removal of the load. 3.7 Weighing Test All boats of the contract shall be weighed using a certified weigh-bridge. The boat shall be complete in all respect except that no crew, fuel or stores shall be onboard. Once weighed no further items or fittings shall be placed onboard until all tests and trials are completed. The report shall include list of items/fittings not on boat at the time of test and shall quote their individual weights. In addition Class approved Light Weight calculations based upon draft survey is to be submitted for each boat. 3.8 Inclining Experiment To be carried out as per Class requirements.
