A Proud History in Creating Loading Arms

Loading arms are a type of equipment that loads fluids into tankers and tank trucks. In 1955, by becoming the exclusive Japanese distributor for US company Chiksan Corporation (currently FMC Technologies Inc.), the world's first developer and manufacturer of all-steel loading arms, our predecessor Tokyo Boeki Shokai became the first Japanese company to handle loading arms, and in 1959, started technical collaboration with Chiksan Corporation. Since then, we have moved forward with switching to Japanese production of loading arms and related equipment and facilities, as well as with active technical development. As a result, we now produce a wide line-up of products that can handle the safe loading and unloading of fluids that include petroleum and petrochemical products, high-pressure gas, and other special fluids at a range of temperatures that range from the very high through to the very low.

1.Marine Loading Arms

niikata2Marine loading arms were first made commercially available in 1956 by US company Chiksan Corporation. Until this point, rubber hoses were the main method used for fluid loading and unloading on ships, but loading arms have eliminated concerns regarding extension or bending, improving the safety and efficiency of loading and unloading operations, and enabling smooth, rapid operations even in difficult conditions. Loading arms are now consequently used in ports around the world for many of these operations. Our marine loading arms support small through to very large tankers, and can handle loading and unloading operations for cryogenic liquids such as LNG (-162°C) through to materials with high melting points such as molten sulfur (120°C) and asphalt (180°C), as well as sulfuric acid and caustic soda, or slurries combining solids with liquids.
Our loading arms are still in use 50 years after their installation, and have proved themselves to have outstanding functionality and durability.

We can handle all cryogenic fluid loading and unloading tasks. Cryogenic fluids require even more advanced technologies and support, and our Niigata loading arms have proven results. LNG loading arms are installed in most LNG thermal power stations in Japan.

LNG loading arms have been delivered to all LNG thermal power stations in Japan, and these are still actively being used even now half a century since being first installed, with a record of outstanding functionality and durability.

2.Emergency Release System

Emergency Release System

In the event of unforeseen situations occurring during loading and unloading, this system safely disconnects the loading arm from the tanker within a few seconds, without damaging either the loading arm or the fluid being transported within. This system comprises the emergency release system (ERS unit) itself, and its electrical and hydraulic control devices. The ERS unit is installed in all LNG marine loading arms delivered both in Japan and overseas.

        Natural gas can be used as a replacement for oil, and as such, has far fewer impurities, and higher reserves (reserve-production ratio). Worldwide demand is on the increase, with Japan relying on imports for 96% of its supply, and import from distant producing countries requires LNG tankers. When natural gas is cooled to -162°C, it becomes a liquid, becoming 1/600 of its original volume, enabling efficient transport by tanker. Japan is the world's largest importer of natural gas, and its loading and unloading depends on cryogenic loading arms. TBM provides loading arms as well as a range of related equipment used in loading and unloading in cryogenic environments.

By utilizing a double seal mechanism that increases sealing capability, and utilization of an "external pressure water seal" that works in the same way as a washer prevents entry of water inside the ball bearing section. The body is made of stainless steel because of its outstanding low-temperature characteristics.

2.Niigata Butterfly Valves

Niigata Butterfly Valves

Drawing upon our rich accumulation of technologies, these Niigata butterfly valves have internal diameters of up to 48 inches, and exhibit excellent performance and ease of operation even in cryogenic (low-temperature) environments. These are API607 fire-safe certified, and suitable for use in applications where fire resistance is required. Niigata butterfly valves are some of our best-selling products, and we are proud of their long history of installation, both in Japan and overseas.
