MSHS On-site Services is known all over the world for on-site mechanical machining and for in-situ motor overhaul. MSHS is a highly recognized expert for the reconditioning of diesel engine components such as crankshafts, liner landing and sealing surfaces and main bearing pocket line boring.
When the journal surface is damaged by a bearing failure, the crankshaft is usually removed and machined on a stationary crankshaft grinding lathe causing dismantling and transport costs as well as asset downtime. With our on-site machining tool we offer on-site crankshaft journal repair, repairing the journal on-site, without disassembling the engine and the need to transport the crankshaft to ashore workshop facility.
Our on-site machining tool uses the fillet radii of the crankpin as a reference for adjusting the on-site repair machine. In case these fillet radii are damaged or not centered to the central axis, MSHS has developed a special machining method and the necessary devices to enable the processing of crankpins and main bearing journals to restore them in accordance with the manufacturer tolerances.
With this method, the fillet radii are first machined, then the damaged journal. It is necessary that the mobile device is as precisely as possible adjusted to the base line of the crankshaft using specialized electronic measuring instruments. This method can even be performed at sea, on-site your vessel.
Since we have a large number of special transportable mobile machining tools and or appropriate machines at our disposal, we are able to implement all types of mechanical machining in the field or on-site. The advantages of mobile machining include minimal disassembly and transport costs of large and heavy parts. On-site machining reduces down time and saves you time and money.
Completing repairs on marine diesel engines, auxiliary generators and other equipment is always time-critical. This being the case, our teams can be on duty 24 hours a day. All techniques, e.g. milling, turning, boring, optical device-guided boring alignment, grinding and honing can be executed on-site with our equipment. Our devices are designed so that they can be used on-site, in the smallest of spaces.
Plane surfaces that are no longer flat and therefore cause leakages, e.g. at flanges or damages at live rings, are mechanically machined on-site with mobile turning devices. The requirements for the tolerances are restored in the process.
Bearing channels, bores, turbine housing, threads etc. are mechanically processed on location with transportable drills and turning devices in order to ensure the required tolerances.
Presses, roll housing, turbine housing, machine foundations etc. that are no longer in accordance with the technical requirements are mechanically processed on-site through mobile milling units. The tolerances demanded are thus restored. Shaft and journal processing journals, crankpins, shafts etc. are turned and ground on location with mobile turning devices in order to restore the required tolerances.
Ball races on rotary kilns, paper or other cylinders etc. that no longer correspond to the geometrical prerequisites are turned and ground with our mobile grinding devices so that they again meet the requirements.
The cutting of large cross sections is often very time-intensive. We thus offer various saws for mechanical machining. The positive aspect lies in the fact that large cross sections are split while saving time and without the need for heat input.
It is often unclear as to whether damage to a machine has resulted from a geometrical fault. We offer a variety of measuring devices that are employed before, during and after processing. Included in these, among others, are lasers and optical devices for measuring center lines and surfaces. An engine failure on a vessel or stationary power plant can cause extremely high costs and tremendous downtime. Our on-site and in-situ machining services eliminate costs and save time as disassemble, removal and transport of the damaged parts are not required. Maintenance and in-situ mechanical machining is performed on site by our competent expert personnel to help you minimize your downtime, reducing your costs dramatically.
The repair of broken, cracked or damaged cast parts is always a great challenge, since cast iron is only weldable to a limited extent. Thanks to the procedure that we apply, we can offer an attractive alternative, which nowadays is the preferred method used in industry and marine shipping.
Cracks in various machine parts made of steel and steel casting are generally repaired by caulking, grinding or milling on-site and then welded by preheating. The most widely used welding process for such work is the manual arc welding method. During and after welding, additional heat treatments are generally needed.
We perform heat treatments in the widest variety of forms and sizes. An in-situ heat treatment can be implemented in stationary furnaces or directly at the location of the customer with our mobile annealing equipment.

Reconditioning and repairing presses and machine tools made by the widest variety of manufacturers. This includes presses of all tonnages, grinders, milling machines, boring mills, and turning machines of any size. Well-informed, trained experts are available to provide these services for you, either in our workshop or on-site. Support of the mechanics from a large machinery department is always ensured.
Machine tools are reconditioned according to DIN. This means that the original manufacturer quality is restored. In addition to these measures, a modernization of the control system can be implemented in the case of a major overhaul.
Our workshop is equipped with the widest variety of cutting machines, which allows for flexible and professionally qualified manufacturing.
Machines and production equipment are often utilized to their capacity limits. In the event of damage, the problem of having to acquire spare parts can arise. As an alternative solution, we can offer you the rapid manufacture of replacement parts based on samples or sketches.
Of course, we also offer the remanufacture and repair of components, as well as the realization of manufacturing segments of any kind.
