Witherby: Ship to Ship Transfer Guide for Petroleum, Chemicals and Liquefied Gases

This cross industry publication developed jointly by ICS, OCIMF, SIGTTO and CDI provides guidance on planning and execution of STS operations. It is applicable to all ships involved in transfer activities and to all types of bulk liquid cargoes, whether transferred at sea or in port. It will benefit Masters, Marine Superintendents and others, such as STS service providers and transfer organisers, involved in STS operations.

This industry guide provides recommendations on safety, minimum equipment levels and good operating practices for STS operations. It is a required publication on the SIRE Vessel Inspection Questionnaires (VIQ) for Oil Tankers, Combination Carriers, Shuttle Tankers, Chemical Tankers and Gas Tankers.

This book supersedes:

• Ship to Ship Transfer Guide (Petroleum) 4th Edition published in 2005
• Ship to Ship Transfer Guide (Liquefied Gas) 2nd Edition published in 1995
• LNG Ship to Ship Transfer Guidelines published in 201.1

This book builds on the previous recommendations and recognises experience gained in the industry of STS transfer operations, including transferring chemical (MARPOL Annex II) and liquefied natural gas (LNG) cargoes. The guide is applicable to transfers involving all bulk liquid cargoes, but where specific recommendations relate to a particular cargo type these can be found in the appendices. For transfers involving Annex I cargoes, the guide supports the requirements and recommendations developed by the International Maritime Organization (IMO).
