Among the many on-going LNG projects at SSPA is one that investigates the possibilities of developing a more effective infrastructure for access to LNG for the mari- time market.The aim is to identify potential locations of new maritime terminals for import of LNG to Swedish ports. Location criteria and important parameters In order to find out which of these ports are the most appropriate location of a new LNG terminal, several areas need to be taken into account. Perhaps the most important factor is the strategic geographic location of the port, which includes not only the amount of suitable and interested traffic in the port, but also the possibilities of offering quick, effective and customised bunkering solu- tions to all types of traffic. One of the main parameters that a port must con- sider before deciding to establish a LNG terminal is the available market for bunkering of LNG.The potential maritime market must not only be evaluated on the basis of the current situation, but also with a future perspective in mind. Depending on the political incentives and the outcome of the current discussions on how the future regulations on emissions of SO X and NO X will actually be fulfilled, the number of LNG fuelled vessels may vary. One should also consider that a ship based import of LNG can further improve the supply security and flexibility for other users of natural gas, which are today dependent on a working pipeline network or truck deliv- eries (e.g. industry and land transport). Synergy effects, however, are highly dependent on an effective distribution system on the landside. From big scale to small scale Currently, the most common type of LNG tanker is the import type of vessel, with common sizes in the range of 80 000 m 3 – 260 000 m 3 These vessels are used for large scale import of LNG and they typically travel from producing countries, such as Qatar, to end users in USA, Europe or South Korea.These vessels are too large to be used for import to smaller terminals, and the only terminal planned for in Northern Europe for this type of import tanker is Świnoujście in Poland. Among the smaller LNG tankers, feeder vessels, with sizes between 7 500 m 3 – 20 000 m 3 are becom- ing more common, especially in Northern Europe.These types of vessels are ideal for the smaller coastal and inland waters traffic and they can be used for distribut- ing LNG to smaller terminals in ports along the Swedish coastline. The key issue for maritime use of LNG as a fuel is still bunkering. Onshore installations could be difficult to integrate with a port infrastructure and trucks can only supply smaller amounts of fuel within a given timeframe. Thus, a bunker vessel is most often needed in order to achieve an effective bunkering solution that can provide sufficient amounts of LNG within a reasonable time.

Due to the upcoming regulations on sulphur emissions, LNG as a marine fuel has become a more interesting alternative in the last few years. However, in order to become a realistic alternative to today’s oil products, LNG must also be available for bunkering in ports. Hence, an effective infrastructure for LNG is essential in order to make it feasible as a new fuel for the mari-time market. LNG related studies have been an important area at SSPA for many years and a large share of today’s LNG fleet has passed SSPA’s tests and design support. Clients have consulted SSPA for studies and advice on LNG key issues such as terminal layout, port operations, risk analysis, bunkering operations, and infrastructure devel-opment.
