SCOPE
1.1 The guide provides information and clarity to support the health and maintenance of Marine Sanitation Devices (MSDs) on maritime vessels and platforms to promote effective operations and performance throughout the lifecycle. This includes identification of chemicals and their derivatives that can be detrimental to proper MSD operations. This guide will promote better understanding of the impacts of certain chemicals on the health and operations of MSD systems, plus provide guidance to inform operators of best practices and procedures for effective operations and maintenance. This guide is designed to assist both operators and MSD Original Equipment Manufacturers (OEMs) in collaboratively working to ensure effective operations and maintenance, and to reduce performance degradations that result from the introduction of harmful chemicals. The primary application of this guide is to Type II MSDs (described in Section 4), installed on larger ships and employing biological treatment of sewage and gray water.
Note 1: This guide does not constitute regulations or ship classification society rules, which should be consulted where applicable.  
1.2 Manufacturers preparing new product specifications or revising existing ones should follow the practices and procedures outlined herein, and be guided by the latest specifications covering similar commodities. Similarly, vessel owner/operators should consult this guide regarding in-service operations and maintenance.  
1.3 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.  
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.

SCOPE
1.1 Objectives—Guidelines are provided for the design, construction, and operation of an Accommodation Service Vessel (ASV) intended to provide accommodation services to an offshore installation. The goal of these guidelines is to focus attention on the safety aspects of design. These guidelines are recommended for each vessel providing accommodation service to an offshore installation for more than 36 persons.  
1.2 Relationship with Regulatory and Classification Standards—This guide covers information for designing, constructing and operating ASVs and includes considerations not generally addressed in classification or statutory requirements intended for traditional cargo or passenger ships. While portions of this guide may refer to standards, it is not intended to supersede any classification or statutory requirements.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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.  
1.5 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.

ISO 20283-5:2016 gives guidelines for the measurement, evaluation and reporting of vibration with regard to habitability for all persons on-board passenger and merchant ships, especially for crew. Overall frequency-weighted r.m.s. vibration values in the frequency range 1 Hz to 80 Hz are given as guideline values for different areas on ships. ISO 20283-5:2016 is applicable to passenger and merchant ships with intended voyages of 24 h or more. ISO 20283-5:2016 specifies requirements for the instrumentation and the procedure of measurement in normally occupied spaces. It also contains analysis specifications and guidelines for the evaluation of ship vibration with respect to habitability. The evaluation of low-frequency ship motion which can result in motion sickness is covered by ISO 2631‑1. For the evaluation of the global structural vibration of a ship, however, see ISO 20283‑2.
