During operation, key areas of ships—such as the hull, deck, and inner cabin walls—are highly susceptible to corrosion caused by seawater exposure. Traditional manual grinding for rust removal is inefficient (only 20–30 m² per person per day) and often fails to remove rust completely, leading to poor coating adhesion and premature peeling. High-pressure water jet cleaning, on the other hand, requires large amounts of fresh water and may potentially damage the metal structure of the vessel.

PES LASER provides an efficient and environmentally friendly rust removal solution for the shipbuilding industry. For external ship hull surfaces, laser cleaning equipment combined with a lifting working platform can be used. With laser power ranging from 50W to 6000W, the system effectively removes rust layers of 30–50 μm thickness and can penetrate deep into oxidized gaps on the hull surface. After cleaning, the surface roughness reaches Sa2.5, fully meeting the requirements for subsequent coating processes.

For confined spaces inside ship cabins, portable handheld laser cleaning machines offer flexible operation. Equipped with anti-slip handles and protective goggles, operators can safely and efficiently clean common marine-grade steel such as AH36 and DH36 without causing any damage. The process requires no water, eliminating wastewater discharge and preventing marine pollution. In addition, the system supports battery-powered operation, allowing 4–6 hours of continuous use on a single charge. This significantly reduces dry dock maintenance time, minimizes vessel downtime, and lowers labor costs for rust removal by 30%–40%.
