28、 200 Machinery survey arrangements201 The different machinery survey arrangements are basedon the same inventory list established for the vessel.The dif-ference is the conditions for obtaining and maintaining the sur-vey arrangement.If a survey arrangement is not specified,Machinery Renewal is set a
29、s default.The following survey arrangements are available:Machinery Renewal,see B Machinery Continuous,see C Machinery PMS(Planned Maintenance System),see D Machinery CM(Condition Monitoring),see EB.Machinery RenewalB 100 General101 Machinery renewal is the default survey arrangement formachinery.10

32、3Instrumentation and automation for vessels without notation E0 or ECO2331)The survey methods are defined as follows:Survey method No.1:Visual inspection by opening up fully or partly.Function testing and or pressure testing to be carried out when relevant and found necessary by the surveyor.Survey
33、method No.2:Visual inspection without dismantling and performance test to be carried out.Opening up if found necessary.Last overhaul to be verified.Survey method No.3:Audit of maintenance history in the planned maintenance system and selected spot checks.Survey method No.4:Audit of condition monitor
34、ing results.Survey method No.4*:Audit of condition monitoring results.FFT analysis mandatory.2)As an alternative to Survey method No.1,a performance test and a condition analysis may be carried out.3)Selected bearings shall be examined.Gears and roller bearings may as far as practicable be inspected
35、 without dismantling complicated assemblies.4)Strainers to be opened.Selected pipes and main engine(s)system tanks to be surveyed for sludge.5)Valves,cocks and strainers to be opened.6)For steam pipes with temperature 450 C and above:Crack detection and/or thickness examination may be required.Selec
36、ted pipes to be pressure tested to 1.5 times working pressure.Steam pipes of copper to be pressure tested to 2 times working pressure7)To be pressure tested to 1.2 times working pressure if internal survey not possible.8)For piping systems outside machinery spaces,see Ch.2 Sec.2 C214.9)Settling tank
37、 and daily service tanks for both heavy fuel oil and diesel oil as well as lubrication oil circulation tanks shall be internally surveyed for as-sessment of tank condition and presence of sludge.If inspection and cleaning of above mentioned tanks have been carried out by the crew during the last 12
38、months and relevant log extracts are provided and confirmed,this may be credited as surveyed at the surveyors discretion.10)Valves where the function in the piping system is not evident are to be adequately and readably marked,see Ch.2 Sec.2 Table C5.11)Filters to be opened and system oil tanks inte
39、rnally surveyed for presence of sludge,dirt and particles.12)It is advised to take oil analysis at regular intervals and always prior to docking in order to ensure that there is no need for opening of the thruster(e.g.water in the oil).13)Survey of gear and bearings through inspection openings or by
40、 other means(may be carried out concurrent with bottom survey).14)Opening up and Survey of bearings,gear and shafts and other relevant parts if any indications of abnormalities are observed.Satisfactory maintenance according to manufacturers recommendations to be documented and considered as a base
41、for extent of possible opening.Any opening up of a thruster to be witnessed by a DNV surveyor.15)Hydraulic oil,lubrication oil,alarm and safety systems are to be surveyed as applicable for respective systems.16)In addition to the renewal survey for Machinery CM,a limited internal inspection shall be
42、 carried out on main steam turbines.(ref.CN 10.2 Ch.3.1)Table A1 Machinery surveys(Continued)ItemMachinery Renewal and Continuous MachineryMachinery PMS Machinery CMSurvey method 1)Rules for Ships,January 2003 Amended,Pt.7 Ch.8 Sec.1 Page 8 see Pt.0 Ch.1 Sec.3,January 2006DET NORSKE VERITASB 300 Ren

46、equipment are credited based on documented main-tenance history presented by the chief engineer under thefollowing conditions:1)The following information shall be available:name of the chief engineer licence number,date of issue and validity name of the Administration that issued the licence.The man
47、ager shall confirm,through a statement signed bya designated person in the company,the chief engineersthat can carry out surveys based on sub-items 2 to 5.Thisstatement shall be found onboard.Guidance note:A template for such a statement is available from DNV.For thedefinition of a designated person
