OSM helps you understand what can be repaired and how before you commit to costly removal or replacement. We provide onsite machining, crankshaft damage assessment, NDT and workshop machining for marine, power generation, offshore and industrial equipment.
You do not need to know the machining process before calling us.
The setup is designed around the component, geometry and access.
The right repair location depends on the actual job.
Understand what we propose, why we propose it and how it benefits the repair.
Before you commit to costly removal or replacement, OSM works with you to understand the condition, the practical options and the most sensible repair route.
Sometimes the answer is onsite machining. Sometimes workshop machining is the better option. Sometimes replacement or another repair route makes more sense.
Our job is to look at the technical facts and help you make the right decision for the equipment and the operation. We base that on condition, geometry, access, repair feasibility, downtime, cost and the technical result. Safety is a baseline requirement on every job. We will not recommend work that does not make technical and commercial sense for you.
Portable machining equipment is flexible and modular. OSM uses the machine as a tool to solve the geometry, access and repair problem in front of us. The obvious repair is not always the only repair.
A dedicated OSM service following a failure or suspected damage. The aim is to establish the actual condition before deciding how the crankshaft should be repaired. Work may include visual inspection, failure history, geometrical measurements, journal dimensions, existing material removal, radius condition, hardness testing and Magnetic Particle inspection. The findings show whether the practical route is onsite repair, workshop repair, another method or replacement.
Bearing housings, aligned bores and other critical geometry can often be restored in place when the condition and access support onsite machining. OSM establishes the references and geometry first, then develops the setup around the component. Not every bore can be repaired onsite, and we will tell you when it cannot.
Damaged or corroded sealing surfaces on pipework, valves, exchangers and other equipment can sometimes be restored onsite without removing the entire component. The method depends on the geometry, material condition, access and the required final surface. This is also where custom setups matter most.
Journals, seal areas and other shaft features may be restored onsite when the geometry, material condition and repair limits support it. The route is set by the actual condition, not by an assumption that onsite machining is always appropriate.
Portable milling, drilling, tapping, stud removal, cold cutting and bevel preparation allow machining work to be done at the equipment when moving the component is difficult or unnecessary. Cold cutting gives a controlled cut and a clean bevel preparation, with less reliance on handheld grinding.
OSM provides Level II Magnetic Particle and Liquid Penetrant inspection. NDT can support damage assessment, repair planning, crack detection, technical evaluation and closeout documentation. The method depends on the material, component and scope.
Some components are better repaired in the workshop. Each component is received, identified and inspected, and its condition is checked against the customer instructions. Discrepancies are communicated before machining where appropriate. After machining the work is measured, documented, preserved and packaged for transport or pickup.
Customers do not always know which machining process they need. That is fine. Tell us what happened, what you are seeing and what you need to achieve. We will work through the options with you.
We look at the component, failure history, symptoms, drawings, photographs and any measurements already available. If more information is required, we determine what needs to be inspected before recommending a repair.
We consider condition, geometry, tolerances, access, safety, downtime, cost and the required technical result. The answer may be onsite machining, workshop machining, replacement or another repair route.
Portable machines are flexible. The skill is knowing how to reference, align, adapt and configure the equipment around the actual component and geometry. This is where field experience matters.
When OSM performs the repair, the work is completed to the agreed scope. Final dimensions and relevant photographs are recorded and the appropriate closeout documentation is prepared.
Examples of the type of technical problem OSM evaluates. Documented case studies will be added here.
Visual condition, operating history, geometry, hardness and Magnetic Particle inspection can establish whether a damaged crankshaft is a candidate for onsite repair, better handled in a workshop or beyond practical repair.
A damaged internal sealing surface does not automatically mean an entire piping or component assembly must be removed. Where geometry and access allow, custom portable machining equipment may provide another technically viable repair route.
OSM International Services Inc. is based in South Florida and supports marine and industrial customers across the Americas and Caribbean. For appropriate projects, additional resources can be coordinated through OSM Netherlands.
Inspection services and completed machining jobs require different documentation, but the objective is the same: give the customer a clear technical record of the condition, the work performed and the result.
OSM was built around hands on field experience, practical problem solving and direct technical access. The objective is not to sell a machining process. It is to help the customer understand the options and choose a repair route that makes technical and commercial sense.
Founder Mike de Graaf has approximately 25 years of technical field experience. His background began as an F-16 Crew Chief in the Royal Netherlands Air Force and developed through marine field service, onsite machining and crankshaft work. Earlier roles include Goltens, OSM Netherlands, MSHS Metalock Engineering and onsite machining activities related to Wärtsilä and ContiServe. OSM is a return to his roots in onsite machining and crankshaft work.
OSM works with clear scope, clear rates and clear terms, and recommends work only where it makes technical and commercial sense for the customer.
Send what you know. Tell us what happened, where the component is, what you are seeing and what result you need. Photographs, drawings, measurements and reports help.
OSM will review the situation with you and help identify the practical next step.
