22、nce speed and distance measuring equipment (SDME) required by Regulation 19 of Chapter V of the International Convention for the Safety of Life at Sea (SOLAS), 1974, as amended, and which is associated with IEC 60945. This standard is based upon the requirements of IMO Resolution MSC.96(72). The cla
23、use numbering of that resolution is indicated in parentheses in Clause 4 and all subclauses whose meaning is identical to that in the resolution are printed in italics. In the tests of Clause 5, the corresponding requirement of Clause 4 is indicated in parentheses. The cross-references between the I

28、are intended for general navigational and ship manoeuvring use. The minimum requirement is to provide information on the distance run and the forward speed of the ship through the water or over the ground. Additional information on ships motions other than in the forward axis may be provided. The eq
29、uipment shall fully comply with this performance standard at forward speeds up to the maximum speed of the ship. Devices measuring speed and distance through the water shall meet the performance standard in water of depth greater than 3 m beneath the keel. Devices measuring speed and distance over t
30、he ground shall meet the performance standard in water of depth greater than 2 m beneath the keel. Radar plotting aids/track control equipment require a device capable of providing speed through the water in the fore-and-aft direction. b) (MSC.96(72)/A1.3) In addition to the general requirements in
31、Resolution A.694(17) as detailed in IEC 60945, devices to indicate speed and distance shall comply with the minimum performance requirements of this standard. c) Where SDME information is generated by one unit of equipment and is displayed on another unit, the combination of the two units shall be r
32、egarded as forming the SDME and shall be tested as an entity. d) Any facility provided by the equipment which is additional to the minimum requirements of this standard shall be tested to ensure that its operation (and, as far as is reasonably practicable, its malfunction) does not degrade the perfo
33、rmance of the equipment. e) The system shall consist of a sensor and the necessary processing unit to convert the output signal of the sensor to speed and distance for display and for transmission to other equipment. 4.2 Methods of presentation a) (MSC.96(72)/A2.1) Speed information may be presented
34、 in either analogue or digital form. Where a digital display is used, its incremental steps shall not exceed 0,1 knots. Analogue displays shall be graduated at least every 0,5 knots and be marked with figures at least every 5 knots. If the display can present the speed of the ship in other than the
35、forward direction, the direction of movement shall be indicated unambiguously. b) (MSC.96(72)/A2.2) Distance run information shall be presented in digital form. The display shall cover the range from 0 to not less than 9 999,9 nautical miles and the incremental steps shall not exceed 0,1 nautical mi
36、les. Where practicable, means shall be provided for resetting a read-out to zero. c) (MSC.96(72)/A2.3) The display shall be easily readable by day and by night. d) (MSC.96(72)/A2.4) Means shall be provided for transmitting measured speed and distance run information to other equipment fitted on boar
37、d. (i) (MSC.96(72)/A2.4.2) When the equipment is used for measuring forward speed, then the information may be transmitted using closing contacts and, if so, this shall be in the form of one contact closure each 0,005 nautical miles run. The minimum contact closure time or equivalent pulse width sha
38、ll be 50 ms. (ii) (MSC.96(72)/A2.4.1) The information on all speed and distance parameters, including direction, shall be transmitted in accordance with the relevant international marine interface standards. The equipment shall support at least the sentences VBW and VLW to IEC 61162-1. e) (MSC.96(72
39、)/A2.5) If equipment is capable of being operated in either the “speed through the water“ or “speed over the ground“ mode, mode selection and mode indication shall be provided. Where automatic mode selection is provided, the mode in use shall be indicated. f) (MSC.96(72)/A2.6) If the equipment has p
40、rovision for indicating speeds other than on a single fore-and-aft direction, then both the forward and athwart speeds shall be provided EN 61023:2007 5 either through the water or over the ground. Resultant speed and direction information may be provided as a display-selectable option. All such inf
41、ormation shall clearly indicate the direction, mode and validity status of the displayed information. 4.3 Accuracy of measurement a) (MSC.96(72)/A3.1) Errors in measured and indicated speed, when the ship is operating free from shallow-water effect and from the effects of wind, sea bottom type, curr
42、ent and tide, shall not exceed the following: for a digital display 2 % of the speed of the ship, or 0,2 knots whichever is greater; for an analogue display 2,5 % of the speed of the ship, or 0,25 knots, whichever is greater; and for output data transmission 2 % of the speed of the ship, or 0,2 knot
43、s, whichever is greater. b) (MSC.96(72)/A3.2) Errors in the indicated distance run, when the ship is operating free from shallow water effect and from the effects of wind, sea bottom type, current and tide, shall not exceed 2 % of the distance run by the ship in 1 h or 0,2 nautical miles in each hou
44、r whichever is the greater. c) (MSC.96(72)/A3.3) If the accuracy of devices to indicate speed and distance run can be affected by certain conditions (e.g. sea state and its effects, water temperature, salinity, sound velocity in water, depth of water under the keel, heel and trim of ship), details o
45、f possible effects shall be included in the equipment handbook. 4.4 Roll and pitch (MSC.96(72)/A4) The performance of the equipment shall be such that it will meet the requirements of this standard when the ship is rolling up to 10 and pitching up to 5. Any degradation of performance at roll and pit
46、ch angles greater than those above shall be included in the equipment handbook. 4.5 Construction and installation (MSC.96(72)/A5.1) The system shall be so designed that neither the method of attachment of parts of the equipment to the ship nor damage occurring to any part of the equipment which pene
47、trates the hull could result in the ingress of water to the ship. (MSC.96(72)/A5.2) Where any part of the system is designed to extend from and retract into the hull of the ship, the design shall ensure that it can be extended, operated normally and retracted at all speeds up to the maximum speed of
48、 the ship. Its extended and retracted positions shall be clearly indicated at the display position. The handbook shall include the manufacturers recommendations on the installation of the SDME, in particular the positioning of the sensor, as it affects the overall accuracy of the SDME. 5 Methods of
49、testing and required test results 5.1 General The manufacturer shall, unless otherwise agreed, set up the equipment and ensure that it is operating normally before testing commences. 5.2 Test arrangements The general arrangements for the tests shall be as follows: EN 61023:2007 6 a) where applicable, the units of the equipment shall be inter-connected by the longest electrical links for which the equipment has been designed. A link may be real or simulated; b) for tests to determine speed and distance mea
