Our principal
Engineered by CSSC.
MAST Maritime Services acts as the main agent of the Shanghai Marine Diesel Engine Research Institute (SMDERI), a state-owned, high-tech enterprise of the China State Shipbuilding Corporation. SMDERI researches, builds and services high-tech marine equipment, with professional after-sales support.
Smart design
Split structure.
A special split-half structure and a no-bearing design let the SMDERI shaft generator mount directly on the intermediate shaft, instead of replacing the vessel’s shaft system. The split arrangement avoids dry-docking and brings installation down to about nine days, afloat at any berth.
- Mounted on the existing intermediate shaft
- No dry-docking required
- Installed in about 9–10 days, afloat
- Simple maintenance pattern
- Remote monitoring for operational safety
