Offshore Structure
The IHI Group independently developed SPBTM (Self-supporting Prismatic shape IMO type B) Tanks, which are “LNG Cargo Containment System for LNG Carrier and Floating LNG Unit”. The tanks serve on IHI-constructed LNG carriers that have served safely LNG transportation even in the world harshest sea condition between Alaska (Kenai) and Japan for more than 20 years. As LNG demand expands, companies are exploring the use of floating units to develop offshore gas fields. SPBTM systems have attracted attention worldwide as ideal LNG cargo containment system. FPSO (Floating Production Storage and Offloading) is a floating production system that receives fluids (crude oil and host of other things) from a subsea reservoir and produces, stores and offloads petroleum products to tankers. Our Aichi Works recently completed a one-million-barrel floating vessel that is now operating in Southeast Asia.

Mega-Float, others
The Mega-Float represents like a flat small island, which is actually a floating structural steel providing us with large area for various purpose at offshore location.
The Mega-Float is the most suitable solution in our recycling-oriented society eliminating land based development and achieving minimum impact with the environmental friendly floating structure. It is fabricated in a few shipyards to build large sized floating structures and towed to the offshore site to assemble them to make one purpose built Mega-Float to locate at the operation site. This Mega-Float can be relocated to other offshore site thanking of the nature of floating structure, even though it is huge in size. The Mega-Float is expected to expand its applications such as an airport, offshore power generation plant, disaster prevention stations and so on.
Urban Development
IHI optimizes the potential of our real estate holdings by redeveloping company offices and housing nationwide. We engage in leasing and sales, particularly in metropolitan Tokyo. A good example of this approach is in Toyosu, known for former shipbuilding yards, where we are undertaking a massive urban redevelopment project. We also prioritize using idle land, as part of which we operate Japan’s biggest mega solar generating business, in Kagoshima, thereby contributing to environmental and social sustainability.
