Div Diving Engineering is a Shenzhen-based underwater engineering specialist that has supported the marine, offshore oil and gas, and port infrastructure sectors in southern China since the year 2000. Headquartered in the Nanshan district, the firm sits within a broader corporate group structure that includes domestic offices in Tianjin, Shanghai and Zhanjiang as well as a Hong Kong branch, allowing technicians to mobilise quickly to vessels calling at major ports along the coast and on the Pearl River Delta.
Commercial diving sits at the core of the service portfolio, and inspections are carried out by class-approved diver-surveyors capable of producing reports acceptable to ABS, Bureau Veritas, CCS, DNV and Lloyd's Register. Routine work covers in-water surveys in lieu of drydocking, propeller polishing, sea chest and rudder examinations, anode replacement, cathodic protection checks, weld inspection on bilge keels and bow thruster grids, and underwater video documentation of hull condition. The team also handles hull ultrasonic thickness gauging, non-destructive testing and remote inspection assignments for owners scheduling intermediate or special surveys, with digital UT recordings made available to attending class surveyors.
Tightness and barrier work rounds out the topside scope, with ultrasonic hatch cover testing and watertight integrity checks delivered to bulk carriers, container ships and general cargo vessels. Through its sister entity D&R Subsea, DIV also undertakes EPCC underwater projects for offshore oil and gas production facilities, supporting installation, production and decommissioning phases of subsea fields. This breadth means the company is regularly engaged on assignments ranging from short port calls to long-term offshore campaigns, and it maintains a roster of trained personnel and specialised diving equipment suited to both class-driven survey work and engineering-led subsea interventions across the region.
