MarineShaft is introducing a custom-made mobile lathe for in-situ shaft machining, designed to handle larger shaft diameters and reduce vessel downtime. As part of the company’s continued development of its mobile equipment and in-situ service capabilities, shafts of up to 1,100 mm in diameter can now be machined directly on board or on site, compared with the previous capacity of 800 mm.
The increased capacity is particularly valuable for tail shafts, where damage or wear can lead to costly delays. By carrying out machining operations in situ, shipowners and managers can avoid disassembly, transport logistics and extended downtime, resulting in a faster and more cost-effective repair process.
The upgraded mobile lathe is fully integrated into MarineShaft’s onsite service offering, covering inspection and repair through to installation, alignment and supervision. Combined with an in-house logistics setup managing mobilisation and coordination, the company says this provides an efficient process from start to finish.
According to MarineShaft, the increased capacity and flexibility of the upgraded mobile lathe strengthen its ability to respond to urgent repair requirements worldwide, particularly where traditional supply chains or workshop access would delay operations.
With this development, MarineShaft continues to expand its in-situ service concept, providing complete repair solutions where they are needed.
At SMM 2026, MarineShaft will present a smaller version of its mobile lathe, allowing visitors to experience the in-situ machining concept.
