Ever since ancient civilizations started build large vessels to transport good by sea the use of lightering to facilitate access into shallow water harbours has been a common practice. In more modern times, the lightering of oil and LPG have become well established practices boasting excellent safety records with industry recognized guidelines for such operations developed and refined over time by organizations such as OCIMF, ICS and SIGTTO.

Traditional trading patterns for LNG with dedicated vessels serving projects in point to point trades have until recently dictated that LNG ship to ship (STS) transfers have been restricted to a small number of operations performed for operational emergency or testing purposes. As trading patterns for LNG evolve and new technology is developed, new drivers to perform LNG STS transfers for commercial or routine operational reasons are emerging.

LNG transportation has to date also enjoyed a proud record with more than 40,000 voyages performed without a single major cargo release incident. For this to be achieved vessel and terminal designs have been evolved and operational procedures developed to ensure that a high degree of safety is applied to every step of the loading, carriage and offloading operations. Those involved in the operations are today highly trained and experienced. So, one could be forgiven for thinking that LNG STS will be a simple evolution from tradition LNG terminal operations combined with the principles behind oil and LPG STS operations. In fact, a number of factors related to LNG vessel design, LNG properties, equipment requirements and personnel training and familiarity clearly differentiate LNG from other products when it comes to STS transfers.

Failure to recognize those differences and to identify and mitigate risks associate with such operations could result in a serious incident that could do significant damage to the hitherto proud reputation of the LNG transportation industry.
