The sections in this template shaded yellow are for Guidance or description for the purpose of preparation of the STS Plan only. The user is to delete the contents of these sections or may in their place insert specific requirements that may pertain to the vessel for which the template is being developed. Furthermore, words and sentences with yellow shading are to be deleted. The entire document with or without shading is editable. The only linked fields are the contents of the footer and other locations which indicate the vessel’s name and IMO number.
This document is a template to assist the shipowner/operator/designer in preparing ship-specific Ship-to-Ship Transfer Operation Plan (STS plan), demonstrating compliance with the requirements of MARPOL Annex I, Chapter 8: “Prevention of Pollution during Transfer of Oil Cargo between Oil Tankers at Sea”, Regulations 40, 41 and 42.
Furthermore, this STS Plan template and format has been developed taking into account the guidance contained in the best practice guidelines for STS operations as identified by the International Maritime Organization (IMO) in the following two documents:
Users should be aware that the contents are subject to revision and amendments from time to time, and that partial extracts may be misleading. ABS cannot accept any responsibility for material that may be incomplete or out of date or otherwise in error.

The images and the sections detailing the IMO’s Manual on Oil Pollution and those from the CDI/ICS/OCIMF/SIGTTO “Ship-to-Ship Transfer Guide for Petroleum, Chemicals and Liquefied Gases”, 2013 (STS Guide) are copyright presentations. These may only be used specifically and only in this ABS STS Transfer Operation Plan Template by the user.The STS Plan must be approved by either the relevant flag Administration for the vessel or by a classification society authorized by the vessel’s flag Administration for MARPOL Annex I certification. As ABS is authorized by more than 100 Countries for MARPOL Annex I certification, the completed template should be submitted to an ABS Engineering Office for review.
This document has been developed solely as guidance for the shipowner/operator/designer preparing a Ship-to-Ship Transfer Operation Plan (STS plan) as required by the relevant sections of MARPOL Annex I. Users should refer to the applicable sections of MARPOL as necessary. Users are also urged to consult with their local ABS engineering office should more detailed interpretations be required. Any variation between applicable regulations and the information provided in this document is unintentional, and, in the case of such variations, the requirements of the regulations govern. This guidance does not constitute advice by ABS and may not be relied upon to create a contractual right or benefit enforceable by any person.
Preparation of the STS Plan
Turn on the “Show bookmarks” option: Click “File” tab, then “Options”, then “Advanced”, go to the “Show document content” section, and check “Show bookmarks” checkbox.
On the cover page of the STS plan
1) Insert the ship’s name and IMO number. Make sure that the modifications are within the bookmark brackets shaded in yellow.
2) Click “File” tab, then “Print” (without printing), then go back to the main document to continue editing. Then all the occurrences of ship name and IMO number will be updated.
3) All the subsequent pages where the ship’s name and IMO number are required will be automatically filled in.
4) On completion change the yellow shading to “No Color”
Part A, Section 1 is to include all ship specific details and the Appendices any other STS transfer operation related documentation with supplementary information concerning good practices, liabilities, vessels specific and relevant equipment. Similarly Part B Appendix I is to include vessel specific plans and procedures.
It is imperative that the user of this template tailors its contents to comply with the Flag the vessel flies in addition to the required compliance measures set forth in:
MARPOL Annex I, Chapter 8: “Prevention of Pollution during Transfer of Oil Cargo between Oil Tankers at Sea”, Regulations 40, 41 and 42.
IMO “Manual on Oil Pollution, Section I-Prevention” 2011,
and the guidance detailed in the
CDI/ICS/OCIMF/SIGTTO “Ship-to-Ship Transfer Guide for Petroleum, Chemicals and Liquefied Gases’, 2013 (STS Guide).
“Flag Administrations may have additional requirements for the STS Plan. Please consult with the local ABS Engineering Office”.
This STS plan template includes the latest guidelines. A vessel’s STS plan should not deviate from these guidelines in principle.
However, additional policies and procedures and instructions that are in line with these guidelines are expected to and may be inserted where appropriate. The checklist in the appendices of this document may be supplemented in addition with ship specific checklist that may be required to address particular items that have not been considered by the sample checklist. Supplemental Checklist to not require approval. Additions to the contents of the included Checklist may be permissible but not deletions.
Objectives of an STS Plan
• The STS plan being ship specific, includes all the necessary information and procedures that are required for the safe execution of STS operations.
• The STS plan is a subset of the vessel’s Safety Management System (SMS). Therefore, the objectives of the vessel’s ISM would also be applicable to the STS plan.
Renewal and Approval of an STS Plan
• When the vessel’s flag is changed, the STS plan is subject to be reapproved by the new flag administration.
• If the company of a vessel changes, since the STS plan is part of the SMS, it is expected to reflect the current tanker operator’s specific policies and procedures.
• Whenever a vessel is purchased second hand or a DOC management changes, a new and updated STS plan is to be prepared and approved by the flag administration or its authorized RO thereof.
• An exemption for the need for a re-approval could be considered for cases wherein, the flag of the vessel does not change and the DOC of the handing over company is identical to the DOC of the taking over company, both the companies having the same policies and procedures.
• An STS plan may require re-approval if the applicable guidelines change
In all the above situations confirmation from the tanker vessel’s Flag Administration is to be obtained on the procedure the vessel’s shipowner intends to follow.
Service Provider’s Familiarity of the Vessel’s STS Plan
• As applicable and in association with the IMO Oil Pollution Manual / 22.214.171.124 the vessel’s qualified POAC must have a thorough knowledge of the STS plan and it would be therefore beneficial to submit the STS plan to the service provider prior to the preparation of the Joint Plan of Operation.
Copies and Locations of a Vessel’s Approved STS Plan
• Copies of the STS plan should be available on the bridge, cargo control room and at the engine control room. See Part A/Section 2/126.96.36.199.
