Application The req
23、uirements in this Guide apply to vessels equipped with propulsion and steering systems designed to provide enhanced reliability and availability through functional redundancy. Application of the requirements of this Guide is optional. When a vessel is designed, built and surveyed in accordance with
24、this Guide, and when found satisfactory, a classification notation as specified in Section 5, as appropriate, will be granted. It is a prerequisite that the vessels are also to be classed to either ACCU or eABCU notation in accordance with Section 4/11 of the Rules for Building and Classing Steel Ve
25、ssels. 2. Objective The objective of this Guide is to provide requirements which reduce the risk to personnel, the vessel, other vessels or structures, the environment, and the economic consequences due to a single failure causing loss of propulsion or steering capability. This is achieved through v
26、arying degrees of redundancy based upon the vessels Classification Notations as described in Section 5. The requirements in this Guide aim to ensure that following a single failure the vessel is capable of either; 1. maintaining course and maneuverability at reduced speeds without intervention by ot
27、her vessels, or 2. maintaining position under adverse weather conditions as described in 7.1 to avoid uncontrolled drift, and navigating back to safe harbor when weather conditions are suitable. In addition, this Guide addresses aspects which would reduce the detrimental effects to the propulsion sy
28、stems due to a localized fire in the machinery spaces. 3. Definitions For the purpose of this Guide, the following definitions are applicable: Auxiliary Services Sstem: All support systems (e.g., fuel oil system, lubricating oil system, cooling water system, compressed air and hydraulic systems, etc
29、.) which are required to run propulsion machinery and propulsors. Propulsion Machinery Space: Any space containing machinery or equipment forming part of the propulsion systems. Propulsion Machine: A device (e.g., diesel engine, turbine, electrical motor, etc.) which develops mechanical energy to dr
30、ive a propulsor. Propulsion System: A system designed to provide hrust to a vessel consisting of one or more propulsion machines; one or more propulsors; all necessary auxiliaries; and associated control, alarm and safety systems. Propuhoc A device (e.g., propeller, waterjet) which imparts force to
31、a column of water in order to propel a vessel, together with any equipment necessary to transmit the power from the propulsion machinery to the device (e.g., shafting, gearing, etc.). Steering System: A system designed to control the direction of movement of a vessel, including the rudder, steering
32、gear, etc. GUIDE FOR PROPULSION REDUNDANCY 1 Copyright American Bureau of Shipping Provided by IHS under license with ABS Licensee=Boeing Co/5910770001 Not for Resale, 08/07/2008 20:40:05 MDTNo reproduction or networking permitted without license from IHS -,-,- STD-ABS #BLi-ENGL 1777 m Ob51102 002OL

Plans and Data to be Submitted In addition to the pians and data required by the Rules for Building and Classing Steel Vessels, the following are to be submitted: 0 Results of computations showing that upon any single failure in the propulsion and steering sys
34、tems the vessel is able to meet the capability requirements of 7.1 , if applicable, with details of the computational methods used. (See Note * 1 .) 0 A Failure Mode and Effect Analysis (FMEA) or equivalent. The integrity of the propulsion systems, steering systems and auxiliary services systems is
35、to be verified by means of a Failure Mode and Effect Analysis (FMEA) or equivalent method, and is to show that a single failure will not compromise the criteria as specified in Section 7. 0 A Testing Plan to cover the means whereby verification of the redundancy arrangements will be accomplished. o
36、A general arrangement detailing locations of all machinery and equipment necessary for the correct functioning of the propulsion and steering systems, including the routing of all associated power, control, and communication cables. (Required for R1-S and R2-S only). o Operating Manual as required i

Classification Notations Where requested by the Owner, propulsion and steering installations which are found to comply with the requirements specified in this Guide and which have been constructed a
38、nd installed under survey by the Surveyor, will be assigned with the following class notations, as appropriate. R1 A vessel fitted with multiple propulsion machines but only a single propulsor and steering system will be assigned the class notation R1. R2 systems (hence, multiple propulsion systems)
39、 will be assigned the class notation R2. A vessel fitted with multiple propulsion machines and also multiple propulsors and steering R1-S A vessel fitted with only a single propulsor but having the propulsion machines arranged in separate spaces such that a fire or flood in one space would not affec
40、t the propulsion machine(s) in the other space) will be assigned the class notation R1-S. R2-S A vessel fitted with multiple propulsors (hence, multiple propulsion systems) which has the propulsion machines and propulsors, and associated steering systems arranged in separate spaces (propulsion machi
41、nery space and steering gear flat) such that a fire or flood in one space would not affect the propulsion machine) and propulsor(s), and associated steering systems in the other space) will be assigned the class notation R2-S. Example arrangements for each of the above notation are shown in Figure 5
42、.1. + (Plus Symbol) The mark + will be affixed to the end of any of the above class notations (e.g., R1+, R2-S+) to denote that the vessels propulsion capability is such that, upon a single failure, propulsive power can be maintained or immediately restored to the extent necessary to withstand adver
43、se weather conditions without drifting in accordance with 7.1. The lack of the mark + after the class notation indicates that the vessel is not intended to withstand the adverse weather conditions in 7.1, but can maintain course and maneuverability at a reduced speed under normal expected weather co

Single Failure Concept The degree of redundancy required t
47、o meet the objectives of this Guide are based upon a single failure concept. The concept accepts that failures may occur but that only one such failure is likely at any time. The final consequence of any single failure is not to compromise the propulsion and steering capability required in Section 7
48、 of this Guide, unless otherwise specified. For R1, the single failure criteria is applied to the propulsion machines, its auxiliary services systems, and its control systems. This notation does not consider failure of the propulsor or rudder, or total loss of the propulsion machinery space or steering gear flat due to fire or flood. For R2, the single failure criteria is applied the propulsion machines, propulsors, auxiliary services systems, control sys
