International Forum on Ship to Ship transfer operations 2017
sponsored by TMS TANKERS Ltd.

13 September 2017, City of London


 Quality Criteria on STS Service Providers
The tanker owners' perspective

The event will discuss pertaining matters associated to the quality criteria of STS service providers in accordance to best industry practices. Such organizations should conform to requirements outlined by OCIMF and IMO, in order to effectively provide safety related services to ships involved in Ship-to-Ship transfer operations. Transparency in procedures, of such organizations, associated to their compliance and procedural structure will be presented and discussed.


The scope of the seminar is to establish a rigid conceptual ground for this audit scheme for Ship-to-Ship transfer organizations. Currently the audit of service providers is done only by Oil Companies and traders, as part of an internal procedure or charter party compliance. Lack of transparency neither helps an improved safety culture nor a fair competition amongst STS organizations. It is considered that the assessment criteria should be transparent and known to tanker operators, who bare the upmost responsibility in conducting safely these operations.

Transparency is the key for assisting an improved safety culture, which is the direct interest of tanker operators. Additionally, transparency will consequently improve the sustainability of these operations, which is to the benefit of all stakeholders, regardless the region of their operationd.
