(Omitted as spent—E.R. 4 of 2023)
In these regulations—
Certifying Authority (核證當局) means the Director and any person authorized by the Director and includes Lloyd’s Register of Shipping, Bureau Veritas, Det Norske Veritas, American Bureau of Shipping and Germanischer Lloyd being persons so authorized; Director (處長) means the Director of Marine; lugless shackle (無吊耳卸扣) means a device used for joining cables which in use has an outline in shape and dimensions similar to the links of the cables which it joins; open link or short link cable (開口鏈環或短鏈環錨鏈) means cable constructed of links not having studs; Ordinance (條例) means the Merchant Shipping (Safety) Ordinance (Cap. 369); stud link cable (有檔鏈環錨鏈) means cable in which the links are fitted with studs or a similar component for minimizing deformation of the links when the cable is under load; Supervisor of Tests (測試監督) means an officer of a Certifying Authority who has been appointed as a surveyor of ships under section 5 of the Ordinance to supervise tests of anchors and chain cables in accordance with these regulations; testing establishment (測試場所) means any premises complying with the requirements of regulation 3(1); tonne (公噸) means a metric ton of 1,000 kilograms; verified testing machine (經核實測試機器) means a testing machine complying with and verified in accordance with the requirements of regulation 4.These regulations apply to all anchors and chain cables for use in ships registered in Hong Kong except—
anchors of 76 kilograms or less in weight;
chain cables of less than 12.5 millimetres in diameter;
anchors or chain cables manufactured outside Hong Kong before the coming into operation* of these regulations and first taken on board a ship registered in Hong Kong as part of its equipment not more than 6 months after that date;
anchors or chain cables exempted from these regulations by the Director.
The weight of any anchor shall for the purpose of these regulations be taken to be—
for stockless anchors, the weight of the anchor including its shackle if any; and
for stocked anchors, the weight of the anchor including its shackle, if any, but excluding the stock.
Testing machines used for testing anchors and chain cables in accordance with these regulations shall be installed in premises having proper protection from weather, handling facilities for the articles to be tested, adequate lighting and facilities for proper inspection of the anchors and chain cables after testing.
A testing establishment shall not be used for testing anchors and chain cables unless there is in force a certificate, issued by a surveyor of ships appointed under section 5 of the Ordinance, to the effect that he has inspected and approved the establishment for such use. The person making the inspection shall send a copy of the certificate to the Director, and may revoke the certificate if he ceases to approve the establishment on further inspection. A certificate shall not remain in force for more than 2 years.
Testing machines used for proof load test of anchors and for tensile breaking load test and tensile proof load test of chain cables and their accessories shall comply with the following—
Every tensile testing machine used in a testing establishment shall be of suitable design and construction for its intended duty and shall be subjected to a load verification—
in the case of a new machine or machines not verified under these regulations, before being brought into use; and
in the case of machines verified under these regulations, within 12 months of the last verification, (E.R. 4 of 2023)
and thereafter in both cases at intervals not exceeding 12 months. Verification shall also be made after any major overhaul or when any part affecting the accuracy of the machine is repaired or replaced or when the machine is moved to another site. Every verification required by this paragraph shall be witnessed by a surveyor of ships appointed under section 5 of the Ordinance. Any person undertaking such verification shall report the result to the Director.
The straining arrangement of every tensile testing machine used for tensile proof load tests of chain cable shall be such as to allow such a length of cable as defined in regulation 7(4) to be tested without the need to take a fresh hold to complete the test.
Testing machines used for impact testing of Grade 3 cables shall be suitable for Charpy tests and shall comply with the requirements for such machines specified in British Standards Specification No. 131 : 1959, Part 2, issued by the British Standards Institution.
Application for the testing of an anchor or chain cable shall be made to a Certifying Authority who if they agree to be responsible for the testing shall designate one or more Supervisors of Tests to supervise the testing.
The person applying for the testing shall make available to the Certifying Authority such information about the material from which the anchor or chain cable is manufactured and its method of manufacture as that Authority may require.
The anchor, including its shackle if any, shall be tested by subjecting it on a verified testing machine to the proof load specified as being appropriate to its weight in Schedule 1.
If for the purposes of—
the Merchant Shipping (Safety) (Cargo Ship Construction and Survey) (Ships Built Before 1 September 1984) Regulations (Cap. 369 sub. leg. R),
the Merchant Shipping (Safety) (Cargo Ship Construction and Survey) (Ships Built On or After 1 September 1984) Regulations (Cap. 369 sub. leg. S),
the Merchant Shipping (Safety) (Passenger Ship Construction) (Ships Built Before 1 September 1984) Regulations (Cap. 369 sub. leg. AL), or
the Merchant Shipping (Safety) (Passenger Ship Construction and Survey) (Ships Built On or After 1 September 1984) Regulations (Cap. 369 sub. leg. AM), (E.R. 4 of 2023)
an anchor of special type has been accepted by the Certifying Authority as being as effective as an anchor of conventional design but of greater weight, an anchor of that special type may at the request of the person presenting the anchor for testing be subjected to the test appropriate to an anchor of such greater weight: provided that the weight permitted for this purpose shall not exceed the actual weight of the anchor being tested by more than 33 1/3%.
The anchor, including its shackle, shall be deemed to have passed the test, if after the application of the test it is in the opinion of the Supervisor of Tests without material deformation, flaw or weakness.
Before any chain cable is tested the Supervisor of Tests shall satisfy himself as to the quality of the materials from which the cable is manufactured, the method of manufacture, and its grade ascertained in accordance with Schedule 2.
Chain cable shall be tested by subjecting it on verified testing machines to the tensile breaking load test and tensile proof load test specified respectively in subregulations (5) and (6).
Chain cable of Grade 3 shall in addition to the tests prescribed in subregulation (2) be subjected to mechanical tests in accordance with subregulation (7).
For the purposes of this regulation 27.5 metres of chain cable shall be a length:Provided that—(a)a complete chain cable shorter than 27.5 metres shall be treated as a length;(b)where a complete cable is not exactly divisible into lengths of 27.5 metres the piece remaining shall be treated as a length, except that where such a piece remaining comprises less than 2 complete links it may be included in the previous length.
Tensile Breaking Load Tests—
The number of samples to be taken from lengths of the same grade and diameter presented for testing at one time shall be that set out in Schedule 3 in relation to that grade.
Such tests shall be carried out in the following manner—
A piece of 3 links shall be selected by the Supervisor of Tests and cut from the cable, and the sample so obtained shall be subjected to the tensile breaking load specified in Schedule 4 in relation to cable of the relevant diameter.
If after application of such a test load the sample is unbroken and in the opinion of the Supervisor of Tests is without material flaw or other defect, such sample shall be deemed to have satisfactorily withstood the tensile breaking load.
If the selected sample fails to withstand satisfactorily the appropriate tensile breaking load the Supervisor of Tests shall select another sample of 3 links from the same length of chain cable, as that from which the first sample was taken, and it shall be tested in the manner specified in subparagraphs (a) and (b).
If either the first or second of the 3 link samples withstands satisfactorily the tensile breaking load, each of the lengths which the test sample or samples represent shall be deemed to have passed the tensile breaking load test.
If both the first and second of the selected 3 link samples fail to withstand satisfactorily the tensile breaking load, the length from which the samples were taken shall be rejected and no further testing shall be undertaken upon it.
If required by the person on whose behalf the tests are being carried out, tests may be continued upon any remaining lengths which the test samples represented (if any); in such case each remaining length shall be subjected to tests in accordance with paragraph (ii), and if either the first or second of any 3 link samples selected withstands satisfactorily the appropriate tensile breaking load, that length shall be deemed to have passed the tensile breaking load test.
Where the required tensile breaking load is in excess of 650 tonnes the Director may permit in lieu of the application of the tensile breaking load test specified above such alternative method of testing the tensile breaking load of the material of the selected sample piece as is at least as effective.
Tensile Proof Load Test—
When satisfactory tensile breaking load tests in accordance with subregulation (5) have been made on samples representing any length of chain cable the Supervisor of Tests shall then test every such length separately by subjecting it to the tensile proof load specified in Schedule 4 in relation to cable of the relevant diameter and grade.
The chain cable shall be deemed to have passed such test, if after the application of the test it is, in the opinion of the Supervisor of Tests, without material deformation, flaw or weakness.
Mechanical Tests—
Two mechanical tests—
to determine the ultimate tensile strength and related elongation; and
to determine the impact value,
of the material from which the chain cable is manufactured, shall be carried out on one sample in the case of the test at (a) and on one sample which shall be cut into 3 specimens in the case of the test at (b), taken at places selected by the Supervisor of Tests from every 4 or less lengths of Grade 3 cable of the same diameter presented for testing at one time. The samples shall be deemed to have passed the tests if the tests show that the material continues to be within the limits of mechanical properties set out for Grade 3 cable in Schedule 2.
If the sample fails in the case of test (a) or test (b) a further sample or samples as the case may be shall be selected by the Supervisor of Tests from the same 4 lengths or less as those from which the first samples were taken, and they shall be tested in the manner specified in paragraph (i).
The lengths represented by the samples shall be deemed to have passed the mechanical tests if the samples referred to in paragraphs (i) and (ii) have passed both the test at (a) and the test at (b). (E.R. 4 of 2023)
For the purpose of Schedule 4 the diameter of worn chain cable tested in accordance with this regulation shall be the mean diameter where the cable is most worn.
Before any chain cable accessory is tested the Supervisor of Tests shall satisfy himself as to the quality of the materials from which it is manufactured, the method of manufacture, its grade ascertained in accordance with Schedule 2 and the size and grade of chain cable with which it is suitable to be used.
Subject to subregulation (5), every such accessory shall be tested by subjecting it on a verified testing machine to the tensile proof load test specified in subregulation (3) and samples of such accessories shall be subjected to the tensile breaking load test specified in subregulation (4).
Every such accessory shall be subjected to the tensile proof load test required by these regulations to be applied to the chain cable with which it is suitable to be used ascertained in accordance with subregulation (1).
Except as provided in paragraph (b) at least one from every batch of 25 or less of each type of such accessory of the same dimensions and materials presented for testing at one time shall be subjected to the tensile breaking load test required by these regulations to be applied to the chain cable with which they are suitable to be used ascertained in accordance with subregulation (1).
In the case of end or joining lugless shackles the maximum number in a batch for the purposes of the test referred to in paragraph (a) shall be 50.
If the person presenting the accessories for testing requests that they should be subjected to a tensile proof load only and it is intended that after testing the accessories shall be used as part of a ship’s equipment the accessories need not be tested in accordance with subregulations (2) and (3). In that event the strength of the accessories shall not be less than 40% greater than that of the chain cable with which they are to be used and every such accessory shall be subjected to a tensile proof load test at a load equal to the tensile breaking load test specified in the appropriate table for the cable. Where such tensile proof load test exceeds 650 tonnes regulation 7(5)(v) shall apply.
The accessories shall be deemed to have passed the tests if after application of the tests the accessories are in the opinion of the Supervisor of Tests without material deformation, flaw or weakness.
Mechanical Tests—
Every Grade 3 accessory and accessory incorporating a Grade 3 part which has been subjected to the tensile breaking load test in subregulation (4) shall be subjected to 2 mechanical tests—
to determine the ultimate tensile strength and related elongation, and
to determine the impact value,
of the material from which the accessory or part is manufactured. Such tests shall be carried out on one sample in the case of the test at (a) and on one sample which shall be cut into 3 specimens in the case of the test at (b), taken at places selected by the Supervisor of Tests. The samples shall be deemed to have passed the tests if the tests show that the material continues to be within the limits of mechanical properties set out for Grade 3 cable in Schedule 2.
If the sample fails in the case of test (a) or test (b) a further sample or samples as the case may be shall be selected by the Supervisor of Tests from the accessory or part, and they shall be tested in the manner specified in paragraph (i).
The accessory or part represented by the samples shall be deemed to have passed the mechanical tests if the samples referred to in paragraph (i) or (ii) have passed both the test at (a) and the test at (b). (E.R. 4 of 2023)
If an accessory or part incorporated in an accessory has passed the mechanical tests referred to above all the other accessories in the batch from which it was taken shall be deemed to have passed the mechanical tests.
Where an anchor or chain cable or any chain cable accessory has passed the tests prescribed in these regulations it shall be marked in accordance with the following provisions.
There shall be legibly and permanently stamped in a conspicuous place on every such anchor the particulars set out in Part 1 of Schedule 5 in the relationship and, so far as practicable, in the form set out in figure 1 in the said Part 1.
There shall be legibly and permanently stamped on every such chain cable accessory, and at each end and at intervals not exceeding 30 metres of every such chain cable, the particulars set out in Part 2 of Schedule 5 in the relationship and, so far as practicable, in the form set out in figure 2 of the said Part 2.
The letters indicating the Certifying Authority referred to in the said Parts 1 and 2 shall consist of not more than 4 initials, or 3 initials and a symbol.
Where any anchor, chain cable or accessory is marked in accordance with regulation 9 the Certifying Authority if requested within one month after such marking by the person on whose application the tests were made shall deliver a certificate showing at least the appropriate information as set out in Schedule 6, certifying that the anchor, chain cable or accessory has passed the tests specified in these regulations.
If the Director is satisfied that an anchor or chain cable, or class of anchors or chain cables, cannot appropriately be tested and marked in accordance with the provisions of these regulations, and that it has been tested and marked in an appropriate manner he may exempt that anchor or chain cable, or class of anchors or chain cables, from compliance with all or any of those provisions.
