Shiro Technology Co., Ltd. is based in Zhenjiang, a long-established Jiangsu Province port and shipbuilding city on the south bank of the lower Yangtze with strong concentrations of lifesaving and lifeboat manufacturers and a steady flow of merchant tonnage calling at the city's terminals and at neighbouring anchorages used for crew change, bunkering and routine maintenance. The firm provides on-board technical attendance covering lifesaving, fire-safety and in-water survey scopes for commercial vessels in the Yangtze trading area and the wider East China Sea region. Lifesaving services cover lifeboat and rescue boat annual and five-yearly servicing, davit and launching system load testing, liferaft annual inflation and pressure testing, immersion-suit and lifejacket renewal and overhaul of associated release gear and on-load hooks together with hoist wires, falls and survival pack contents. Fire-safety work covers portable extinguisher recharge, recharging and overhaul of fixed CO2 foam and water-spray installations, fire main and hydrant pressure testing and breathing apparatus maintenance on EEBD and SCBA sets used during enclosed-space drills. Additional disciplines cover lifting appliance and gear surveys supporting cargo-gear certification, pressure vessel inspection on engine-room auxiliary vessels and underwater inspection by qualified diver-technicians supporting in-water surveys in lieu of dry-docking. Shiro Technology holds service supplier recognition by ABS, Bureau Veritas, DNV, the Korean Register and Lloyd's Register, allowing servicing records to be considered during periodical, intermediate and special surveys carried out under SOLAS and class rules on commercial tonnage trading through the East China Sea and Yangtze River corridor.
