Introduction

This Guide is for optional application to ships under ABS Rules for Building and Classing Steel Vessels. It is applied to vessels having design features suitable to permit retrofitting at a future date to install a SOx scrubber system based on existing Class requirements.

The requirements for the arrangement and system design of all features of systems proposed are established in the ABS Guide for Exhaust Emission Abatement (EEA Guide).

It is of course recognized that after the retrofitting of a vessel installed SOx scrubber system, the arrangements and installations will still be subject to approval by the flag Administrations and the flag Administration will implement the IMO requirements in effect at the time of retrofitting. The requirements for the testing, survey, certification and verification of the SOx scrubber system to ensure the equivalent compliance of regulations 14.1 and 14.4 of Annex VI of MARPOL 73/78 are specified in the 2015 Guidelines for Exhaust Gas Cleaning Systems which adopted by International Maritime Organization (IMO) Resolution MEPC.259(68).

This Guide is to be applied to both new construction and existing vessel retrofitting, regardless of size, utilizing SOx scrubber for SOx emissions removal.
