Standard Practice for Thermal Rating and Installation of Internal Combustion Engine Packages for use in Hazardous Locations in Marine Applications

ABSTRACT
This practice covers methods of testing, rating, and installation of internal combustion engine packages used in hazardous areas in marine applications. The purpose of this practice is to thermally rate engine packages, and provide additional installation recommendations to reduce the risk of igniting ignitable mixtures that may be present near the hazardous areas of marine vessels. In this specification, only a marine engine suitable for the service, designed and constructed in accordance with the requirements of 3.2.1, is considered. Thermal rating of the engine is determined by the actual readings of engine and exhausts system temperatures within hazardous areas, as defined by the requirements and references in Practices 2.2 and 2.3 or as designated by the authority.
SCOPE
1.1 This practice covers the method of testing, rating and installation of internal combustion engine packages for use in hazardous areas in marine applications. The thermal rating of the engine is determined by the actual readings of engine and exhaust system temperatures within hazardous areas, as defined by references in Section 2 of this practice, or as designated by the authority having jurisdiction, or both. The goal of this practice is to thermally rate engine packages, and provide additional installation recommendations, in order to reduce the risk of igniting the ignitable mixtures that may be present within the hazardous areas of marine vessels.  
1.2 Only a marine engine suitable for the service, designed and constructed in conformance with the requirements of 3.1.2, is considered.  
1.3 The system of units in this practice shall be SI (metric) form, along with the standard (English) system equivalent placed in parentheses, for example, 20 °C (68 °F).  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ABSTRACT
This specification covers the material, dimensions, and construction of a water trap for diesel exhaust. The diesel exhaust water trap system shall consist of a tank and baffles manufactured from a nickel-chromium-molybdenum-columbium alloy, with gaskets made of nonmetallic materials. A minimum of three baffles shall be installed. The traps shall withstand the maximum temperatures specified, be free of paint, and be so designed such as to prevent sea backwash from entering the diesel exhaust system. The trap and piping systems shall prevent dirt accumulation, with the welding being of small, even beading, free of slag and splatter. Pneumatic proof testing of each trap shall be performed with no visible seam leakage and shall conform to the requirements specified.
SCOPE
1.1 This specification covers the material, dimensions, and construction of diesel exhaust water traps, which shall be required whenever the exhaust is to be expelled through the hull of the vessel.  
1.2 The traps are designed to prevent sea backwash from entering the diesel exhaust system.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Main Propulsion Medium Speed Marine Diesel Engines Covering Performance and Minimum Scope of Assembly

SIGNIFICANCE AND USE
4.1 Comparison of brake horsepower developed and of specific fuel consumption rates from engine to engine may be made by use of data based upon a standard for composition of an engine assembly.  
4.2 The purchaser of the engine assembly will be fully advised of the minimum scope of assembly which the purchaser may rightfully expect to be encompassed by a response to a request for quotation and to be delivered in response to a purchase order unless the engine builder in the proposal or in the offer to sell has clearly advised otherwise.  
4.3 It will be made apparent to the purchaser that additional auxiliary and accessory equipment will be needed to supplement the defined engine assembly when full consideration is given to the application of the engine assembly as a prime mover in a specific vessel.
SCOPE
1.1 This guide covers performance and minimum scope of assembly of all medium speed marine diesel engines intended for main propulsion of single or multiple screw propelled marine vessels or for vessels using other than screw propeller-type main propulsion.  
1.2 This guide is intended to supplement the regulations of legally constituted regulating authorities. In the event of any conflict, which may become apparent after publication of this guide, with such legally constituted regulations, the latter shall take precedence, as may be applicable within the jurisdiction of such authorities and specific to each case, unless such latter regulations are formally waived by proper cognizant authority.  
1.3 This guide is not intended to relieve the purchaser of the obligation fully to advise the engine builder of all of the purchaser’s unique operational considerations to allow those considerations to be satisfied.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Insulation Resistance Monitor for Shipboard Electrical Motors and Generators

ABSTRACT
This specification covers monitoring devices (monitors) for the automatic detection and signaling of low insulation resistance values in idle electrical motors or generators, or both. Monitors are intended for permanent installation in both existing or new panels and controller enclosures designed for marine application. These insulation resistance monitors shall be classified in four types: Type I are alternating current generator monitors, Type II are alternating current generator monitors, Type III are direct current motor monitors, and Type IV are direct current generator monitors. The enclosure materials used in the construction of the monitors are to be flame-retardant and the current carrying terminals shall be made of corrosion resistant material. The monitors shall isolate their measuring circuit from the line voltage, while the motor is operating, by the use of an integral isolating relay. In the design of these monitors, environmental factors shall be considered: operating temperature range, sealing, inclination, humidity, and vibration. Also, the monitor relays, voltage characteristics and operating accuracy shall be considered in the design of these monitors. Each monitor shall be subjected to the following: visual and mechanical examination and operational test.
SCOPE
1.1 This specification covers monitoring devices (monitors) for the automatic detection and signaling of low insulation resistance values in idle electrical motors or generators, or both.  
1.2 Monitors are intended for permanent installation in both existing or new panels and controller enclosures designed for marine application.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.  
1.4 The following safety hazards caveat pertains only to the test method described in this specification:  This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
