25、 All rights reserved vBS ISO 15016:2015ISO 15016:2015(E)IntroductionThis International Standard concerns the method of analysing the results obtained from speed trials.The primary purpose of speed and power trials is to determine a ships performance in terms of ships speed, power and propeller shaft
26、 speed under prescribed ships conditions and thereby verify the satisfactory attainment of a ships speed stipulated by Energy Efficiency Design Index (EEDI) regulations and/or contract. Ships speed is that realized under conditions stipulated by contract and/or EEDI regulations, which are usually; s
27、mooth hull and propeller surfaces, no wind, no waves, no current and deep water of 15C.In general it cannot be expected that all such stipulated conditions will be met during the actual trials. In practice, certain corrections for the environmental conditions have to be considered, such as for water
28、 depth, wind, waves and current12.The purpose of this International Standard is to define the basic requirements for the performance of speed trials, and provide procedures for evaluation and correction of speed trial data, covering all influences which may be relevant to the individual trial runs b
29、ased on sound scientific grounds, thereby enabling owners and others to have confidence in the validity of the final results.This International Standard is intended to help the interested parties achieve the desired target accuracy of, within 2 % in shaft power and 0,1 kn in speed.The procedure spec
30、ified in this International Standard has been developed largely on the basis of published data on speed trials and on ships performance, the more important among them being listed in Clause 2.ISO has invited the International Towing Tank Conference (ITTC) to co-operate on the development of a new st
31、andard for speed/power trials taking into account the new guidelines issued by ITTC and approved by MEPC65 for EEDI. The contribution of the STA-group and the ITTC is highly appreciated.Substitution of terms clauseThis International Standard is generally applied to those ships for which survey and c
32、ertification of EEDI is required under International Maritime Organization (IMO) Resolution MEPC.214(63) as amended by MEPC.234(65). In the case of other ships, to which the above IMO resolutions are not applicable, the terms or phrases of this International Standard are deemed to be replaced as nec
33、essary (e.g. “agreement between the Shipbuilder, the Owner and the Verifier” shall be read as “agreement between the Shipbuilder and the Owner” etc.)vi ISO 2015 All rights reservedBS ISO 15016:2015Ships and marine technology Guidelines for the assessment of speed and power performance by analysis of
34、 speed trial data1 ScopeThe primary purpose of speed and power trials is to determine a ships performance in terms of ships speed, power and propeller shaft speed under prescribed ships conditions and thereby verify the satisfactory attainment of a ships speed stipulated by EEDI regulations and/or c
35、ontract.This International Standard defines and specifies the following procedures to be applied in the preparation, execution, analysis and reporting of speed trials for ships, with reference to the effects which may have an influence upon the speed, power and propeller shaft speed relationship: th
36、e responsibility of each party involved, the trial preparations, the ships condition, the limiting weather and sea conditions, the trial procedure, the execution of the trial, the measurements required, the data acquisition and recording, the procedures for the evaluation and correction, the process
37、ing of the results.The contracted ships speed and the ships speed for EEDI are determined for stipulated conditions and at specific draughts (contract draught and/or EEDI draught). For EEDI, the environmental conditions are: no wind, no waves, no current and deep water of 15C.Normally, such stipulat
38、ed conditions are unlikely to be experienced in part or in full during the actual trials. In practice, certain corrections for the environmental conditions such as water depth, surface wind, waves, current and deviating ship draught, have to be considered. For this purpose, during the speed and powe
39、r trials, not only are shaft power and ships speed measured, but also relevant ship data and environmental conditions.The applicability of this International Standard is limited to ships of the displacement type.In this International Standard, it was decided that the unit to express the amount of an
40、 angle should be “rad” (radian) and that the unit of speed should be “m/s” (metres per second). Nevertheless, “” (degree) as a unit for an angle and “knots” as a unit for speed may be used. However, the units for the angles and speeds which appear in calculation formulas are to be “rad” and “m/s” wi
41、thout exception. Moreover, for the convenience of the users of this International Standard, numerical values using the units of degree and knots are stated jointly at appropriate places.If it is physically impossible to meet the conditions in this International Standard, a practical treatment is all
42、owed based on the documented mutual agreement among the Owner, the Verifier and the Shipbuilder.INTERNATIONAL STANDARD ISO 15016:2015(E) ISO 2015 All rights reserved 1BS ISO 15016:2015ISO 15016:2015(E)2 Normative referencesThe following documents, in whole or in part, are normatively referenced in t
