Masterplan Economic Development Acceleration and Expansion of Indonesia or familiarly called MP3EI are new things that may not be familiar spoken in Indonesia. On the day Friday, May 27, 2011 ago, President Susilo Bambang Yudhoyono, accompanied by the vice president attended the launch MP3EI 2011 to 2025 in the Plenary Hall, Jakarta Convention Center. One, of 17 groundbreaking project, which launched the Floating Storage & Regasification Project Unit (FSRU) in the District of Cilegon.
World energy demand, particularly also in Indonesia is increasingly rising. Indonesia, a country that can be said to be rich in energy resources, especially natural gas. Not all regions in Indonesia has natural gas resources but the demand for fuel is owned by nearly all regions in Indonesia.
Floating Storage and Regasification Unit or often abbreviated FSRU is one solution to meeting the needs of natural gas in order to prevent shortages. Basically, the FSRU is a temporary storage of Liquefied Natural Gas (LNG) aboard a ship is moored. On board the LNG regasification process also occurs, so that gas can be supplied directly to consumers.
Liquefied Natural Gas (LNG)
Natural gas is a gas that consists of several components of light hydrocarbons. The main component of natural gas is methane and the rest are ethane, propane, butane, pentane and nitrogen. The composition of each component varies depending on where natural gas is derived. Natural gas is cooled to a temperature of -162 ± ° C at atmospheric pressure will turn into a liquid so that the volume is reduced by about 1/600 volume of natural gas. Liquid is called the Liquefied Natural Gas (LNG).
Floating Storage and Regasification Unit
FSRU consists of two main component parts, consisting of a number of LNG storage tanks and a regasification system, which are on board. FSRU vessel typically has a length of 350-400 meters wide and up to 70 meters. These boats require a certain water depth (generally 160 ft) to stop. LNG tanks are embedded in the dome-shaped vessel moored on the seabed, with varying storage capacities. The number of tanks is usually more than one fruit. This tank that will accommodate LNG supplied from the outside. LNG from the supplier ships (LNG carriers) are temporarily stored in the storage tank before finally through the gasification process.

LNG regasification process carried out directly on board without having passed or taken to the port first. Regasification unit is usually placed on the main deck of the ship and are usually adapted to the conditions of receiving natural gas. In this process, LNG in liquid form to be heated so that gaseous return. Natural gas is then ready to be streamed to each user of natural gas.

Each piece is either FSRU vessel, LNG tanks, and regasification unit must meet the standards applicable regulations. Utilities and other systems needed to support the FSRU consists of power plants, insturmentasi and control, as well as systems and adequate safety standards.
Overall, the FSRU has a design and components is quite complex combination of shipbuilding technology, natural gas storage systems, and gasification technology. Of course in this article does not contain the FSRU in-depth detail. However, the authors hope this article gives an overview of one of the important projects the government in realizing MP3EI. Hopefully even this project can provide an outlet for gas supply deficit a threat to the industrial users of natural gas in Indonesia.
