Japanese consortium bets on building bobbing bit barns

A Japanese consortium wants to ease the datacenter space crunch by putting servers afloat - but keeping them moored safely alongside port quays. The group comprises shipping and logistics corporation NYK Line, engineering biz NTT Facilities, renewable energy developer Eurus Energy, and MUFG Bank. The quartet has also considered facilities farther out at sea, where they could draw on renewable energy sources such as offshore wind. Others are exploring wave power, including Oregon-based Panthalassa. However, the fab four acknowledge that offshore deployments still face practical hurdles, including maintenance access, high-capacity telecoms links, and independent power supplies. Keeping the floating facilities alongside a quay would let them use existing port infrastructure and nearby generation while the group works toward deployments well beyond the coast. Like others eyeing the waterfront, the consortium reckons bobbing bit barns could help meet growing compute demand without competing for scarce development land, though they would still need somewhere to plug in. We asked the consortium what capacity it expects the facilities to have, and when it anticipates these might be operational, but hadn't received a response at time of publication. NYK Line will oversee development, NTT Facilities will assess the designs, construction, and operation. Eurus Energy will explore renewable power supply, and MUFG Bank will consider financing related ventures. The consortium previously signed a memorandum of understanding with the city of Yokohama for a renewable-powered demonstration at the port. Testing began in March this year. The four may find they face competition in the floating compute farm stakes. Samsung Heavy Industries plans to dip a toe in, saying it expects to have its first facility operational by the second calendar quarter of 2028. (R)
