We design and manufacture Energy Saving Devices (pre-swirl duct and PBCF), and deliver 24/7 main engine repair & maintenance and scrubber repair for all major brands — serving vessels at berths, anchorages and shipyards across China.
Custom-designed and manufactured propulsion efficiency devices. CFD-verified, class-approved and proven in service.
A Pre-Shrouded Duct mounted ahead of the propeller that pre-rotates the inflow, recovering rotational energy losses. Typically 3–8% fuel saving on full-form vessels.
Fins fitted on the propeller boss cap that eliminate the hub vortex, reducing energy loss and propeller cavitation. Typically 2–4% fuel saving, quick to retrofit.
Pre-swirl duct + PBCF combinations deliver up to 3–8% total fuel saving, supporting EEXI compliance and improved CII ratings.
Hull-form and propeller specific design, CFD verification, class-approved fabrication, and installation at Chinese shipyards — with docking or afloat.
Complete main engine and auxiliary engine repair and maintenance — in-situ afloat, at anchorage, alongside or in workshop.
Full M/E overhaul and scheduled maintenance: cylinder units, pistons, cylinder heads, liners, exhaust valves and bearings — in-situ or in workshop.
Turbocharger overhaul and repair: nozzle rings, blading, bearings and seals, performance testing and dynamic balancing.
Fuel pumps, injectors, camshaft and timing gear inspection and repair; precision restoration to maker specifications.
Crankshaft inspection and repair, deflection measurement, bearing renewal, and main engine alignment — supported by senior engineers.
MAN B&W, WinGD, Wärtsilä RT-flex & RTA, Mitsubishi UEC two-stroke engines; medium- and high-speed engines from Wärtsilä, MAN, Caterpillar, Cummins, Yanmar, Daihatsu, Weichai and Hudong.
EGCS repair and maintenance for open-loop, closed-loop and hybrid scrubbers, at anchorage, alongside or during drydock.
Scheduled and emergency EGCS overhauls, annual maintenance packages and class survey support for all system types.
Packing and demister renewal, spray nozzle replacement, blockage cleaning, corrosion treatment, coating and Inconel cladding repair.
Circulating pumps, valves and piping renewal, and scrubber water treatment plant service to restore full system performance.
Gas analyzer / CEMS calibration, sensor checks and data logging support — ready for class, flag and port state inspections.
Senior engineers averaging 15+ years on MAN B&W, WinGD and Wärtsilä engines — hundreds of successful M/E overhauls and scrubber repairs delivered.
Teams at Qingdao, Shanghai, Ningbo-Zhoushan, Dalian, Tianjin, Guangzhou and beyond — at berths, anchorages and shipyards.
One call or email and our engineers mobilize immediately. Afloat repairs at anchorage minimize off-hire and deviation.
From ESD design and fabrication to engine and scrubber service — a single accountable partner for efficiency and reliability.
Wherever your vessel calls, our service teams and spare parts network are already there — or on the next ferry out.
Energy Saving Devices (ESD) are hydrodynamic appendages that improve propeller efficiency. Our pre-swirl ducts and PBCF (propeller boss cap fins) typically save 3–8% fuel, verified by CFD analysis, and support EEXI compliance and CII rating improvement.
We repair and maintain EGCS scrubbers of all major brands, including Wärtsilä, Alfa Laval PureSOx, Yara Marine, CR Ocean Engineering, Langh Tech, Clean Marine, EcoSpray, VEIA and Chinese systems.
Yes. Our teams carry out M/E repair and maintenance afloat at anchorages and berths across Chinese ports, 24/7, keeping off-hire time to a minimum.
For vessels at Chinese ports, engineers and spare parts are typically mobilized within 24 hours of your call or email.
Wherever your vessel is in China, our engineers are one call away. Email or call us any time — day, night, weekend or holiday.
