Vessel in port. Inspection due. RWO part needed now.
Chief Engineer requesting emergency spare. Where to order???
Need genuine RWO part. Not a copy. Not grey market.
Coalescer failed. Vessel cannot depart. Need stock now!
OWS alarm triggered. Port State Control tomorrow!!!
WHY IT MATTERS
Grey market costs more.
A failed PSC inspection. An OWS that reads non-compliant. A part that doesn't fit. When your vessel is in port and time is the constraint - the premium you pay for genuine RWO parts is nothing compared to the cost of getting it wrong.
We supply only genuine RWO components. No substitutes. No grey market.
