1、 Guide for SOxScrubber Ready Vessels GUIDE FOR SOXSCRUBBER READY VESSELS OCTOBER 2015 American Bureau of Shipping Incorporated by Act of Legislature of the State of New York 1862 Copyright 2015 American Bureau of Shipping ABS Plaza 16855 Northchase Drive Houston, TX 77060 USA Foreword Foreword Inter
2、national, regional, national and local air emissions legislation is driving the development of primary machinery technologies to reduce exhaust emissions, together with the use of alternative cleaner fuels, such as LNG, and secondary exhaust emissions aftertreatment systems. Key amongst these emissi
3、ons drivers are the gaseous exhaust emissions legislated through IMO MARPOL Annex VI Regulations 13 and 14 for nitrogen oxide emissions from diesel engines and sulfur oxide emissions from all fuel burning equipment onboard. The IMO limits SOxemissions by regulating the sulfur content of marine fuels
4、 with 0.1% for the emission control areas effective from 1 January 2015 and the anticipated global sulfur limits to 0.5% effective from 1 January 2020 (subject to review in 2018). Additionally, all ships to use fuel with a maximum sulfur content of 0.10% when at berth (including at anchor) in EU por
5、ts since January 2010 and beginning in 2020, the EU will limit sulfur in fuel to 0.5% for operation in EU territorial seas irrespective of the outcome of any IMO determination in 2018. All these will promote increasing use of exhaust gas cleaning systems, such as SOxscrubbers as an alternative to lo
6、w Sulphur fuel. The air emissions performance testing, statutory certification, and statutory survey aspects are regulated through MARPOL Annex VI with any proposed alternative means of compliance, such as exhaust gas cleaning systems, permitted through Regulation 4 in association with any applicabl
7、e IMO Guidelines. At the time of issuance of this Guide, the applicable Guidelines for SOxexhaust gas cleaning systems are IMO Resolution MEPC.259(68) 2015 Guidelines for Exhaust Gas Cleaning Systems, adopted on 15 May 2015. Acceptance of an exhaust emission abatement system as an alternative under
8、MARPOL Annex VI is subject to approval by the flag Administration of the vessel. Users of this Guide should be aware that due to changing regulations, and depending on specific geographical uses, compliance with this Guide may not necessarily reflect all requirements in all regions at the time of co
9、nstruction or future retrofitting. The intent of this Guide is to provide guidance to shipowners and shipbuilders indicating the extent to which a ship design has been prepared or “ready” for the installation and operation of a scrubber for SOxemissions removal. The actual ABS requirements to be app
10、lied for a SOxscrubber are detailed in the ABS Guide for Exhaust Emission Abatement (herein after referred to as the EEA Guide). The purpose of this Guide is to indicate the extent to which a vessel has been prepared or “ready” for compliance with the EEA Guide. Compliance with the applicable editio
11、n of the EEA Guide in force at the time the “SOxScrubber Ready” service is provided does not guarantee compliance with the edition of the EEA Guide as may be applicable at the time of the SOxscrubber retrofit. The EEA Guide has been developed in order to provide guidance for the design and construct
12、ion of exhaust emission abatement systems, focusing on SOxscrubbers, SCR systems, and Exhaust Gas Recirculation (EGR) arrangements, and may be applied to all vessel types. An exhaust emission abatement system is considered approved upon verification of compliance with both the ABS requirements and t
13、he applicable IMO Regulations and Guidelines. Whilst compliance with the applicable IMO Regulations and Guidelines is a pre-requisite for ABS approval and notation, this Guide covers only the Classification approval aspects and statutory approval would be made by ABS as a separate parallel process i
14、n the capacity of a Recognized Organization for the vast majority of flag Administrations. Despite the foreseen trend of using SOxscrubbers, the decision of building a new ship or retrofitting an existing one is not simple, due to the current uncertainty with the entry into force of the 0.5% global
15、sulfur limit and the cleaner fuel alternatives such as LNG. However, considering the promise of the advantages that may be gained from use of SOxscrubber, the shipbuyers may decide to place ship orders with additional provision for using a SOxscrubber with the intention to complete installation in t
16、he future. This arrangement may be called “SOxScrubber Ready”. In order to facilitate future modifications, the shipbuyers and shipbuilders must make a significant effort to figure out what features should be incorporated on a vessel and incorporate these in the shipbuilding contract. ii ABSGUIDE FO
17、R SOx SCRUBBER READY VESSELS .2015 This Guide has been developed considering that the following elements may be desired by owners opting for features of SOxScrubber readiness in the Classification of their vessels. i) The first is an independent and public recognition that a vessel has been designed
18、 intentionally with feasible retrofit of a SOxScrubber in mind and that it has physical features that make it suitable for such a retrofit. ii) The second addresses the need for owners to specify instructions to the builder in terms of Class guidance and requirements. iii) The third provides confirm
19、ation to the owner and the shipbuilder that any vessel features agreed between the two parties have been approved by the Classification society based on their requirements that would be applied if the vessel had been built with a SOxScrubber to the concept proposed. This Guide becomes effective on t
20、he first day of the month of publication. This Guide becomes effective on the first day of the month of publication. The applicable edition of the ABS Rules for Building and Classing Steel Vessels (Steel Vessel Rules) is to be used in association with this Guide. Users are advised to check periodica
