ANATOMY OF A REPAIR

ONE CREW.
EVERY SURFACE.

Most failures live on the same driveline. Select a zone to see how OSM restores it to OEM tolerance, in place and without removal wherever possible.

OUR PROCESS

FIVE STEPS.
ZERO SURPRISES.

Contact & Initial Assessment
STEP 01

Contact & Initial Assessment

Call our 24/7 line with details on your vessel, plant, or rig. We review the failure mode, operating constraints, and your schedule, then issue a preliminary action plan and a mobilization window.

Certified N.D.T. Inspection
STEP 02

Certified N.D.T. Inspection

On arrival, SNT-TC-1A Level II specialists run visual, ultrasonic, magnetic particle, and dye‑penetrant inspections. The condition gets documented in a class‑ready report accepted by DNV, Lloyd's, ABS, and Bureau Veritas.

Mobilization of Tools & Specialists
STEP 03

Mobilization of Tools & Specialists

We ship calibrated portable machine tools, alignment systems, and the right crew of machinists and technicians straight to your site. Caribbean shipyard, offshore unit, inland power plant: we set up wherever the work is.

Onsite Precision Machining
STEP 04

Onsite Precision Machining

We machine in‑situ to OEM or agreed repair standards. Components stay installed wherever possible, so you avoid heavy lifts, engine removal, and long dry‑dock stays and keep critical systems available.

Verification, Reporting & Support
STEP 05

Verification, Reporting & Support

Final checks combine dimensional measurements, NDT as needed, and functional tests. You receive a detailed report with before/after data for class and insurers, plus recommendations for future monitoring.

THE OSM DIFFERENCE

ZERO
DRYDOCKS
REQUIRED

Our portable machining equipment comes to you: dockside, at anchorage, or mid-operation. We restore class tolerances without the cost and delay of a drydock.

01

WE MOBILIZE IN 24 HOURS

When your engine is down, every hour costs tens of thousands. Our Miami-based team deploys globally with air-freight-capable portable machining equipment. We have mobilized to 28+ countries across the Americas, Caribbean, and beyond.

02

CLASS-CERTIFIED WORKMANSHIP

Our SNT-TC-1A Level II certified technicians produce inspection reports accepted by DNV, Lloyd's Register, ABS, Bureau Veritas, NK, and RINA. Every job is documented to classification society standards.

03

NO JOB TOO COMPLEX

A single journal restoration on a 2-stroke main engine. A full crankshaft rehabilitation on a 20,000 TEU container vessel. We carry the expertise and the specialized equipment to execute in any port, on any vessel.

"We don't send project managers. We send trained, seasoned specialists who turn the wheel and read the dial gauge themselves. That's the OSM difference. Your problem becomes our problem to solve."

ABOUT OSM

EXPERT ENGINEERING.
MIAMI SPEED.

Traditional workshop repairs mean disassembly, transport to shore, and long shutdowns. OSM brings precision onsite and in‑situ machining directly to your vessel, plant, or offshore asset from our base in Miami, serving ports and industrial sites across the Americas and Caribbean.

Cut Costs Up to 60%

Skip the heavy disassembly, the haul to an off‑site shop, and the long dry‑dock stay. In‑situ repair cuts total cost well below a conventional overhaul.

Minimize Downtime

Our in‑situ machining crews work on location while your operation stays online wherever safety allows. That cuts days or weeks off a traditional outage.

No Equipment Transport

We mobilize portable machine tools straight to your vessel, rig, or facility anywhere in the Americas and Caribbean. No shipping of large components required.

Class-Approved Results

Repairs performed to OEM or approved procedures, with documentation formatted for DNV, Lloyd's, Bureau Veritas, ABS, and other major class societies.
