OILCHIEF · Oilmaster coalescer-based bilge water treatment
What a DVZ separator code actually names
DVZ's bilge water treatment plants work by coalescing rather than spinning, and the two lines seen aboard are told apart by the designation stamped on the unit's own plate.
OILCHIEF bilge water plants
The OILCHIEF plants are bilge water treatment units rather than centrifuges, and the items that are renewed are the coalescer and filter inserts, the oil content monitor parts, level probes and solenoid valves. Quote the unit type and serial, and send the type approval certificate held aboard with the request. OILCHIEF is also catalogued under the fuller designation DVZ-FSU OILCHIEF, so a plate or stores list reading either name points to the same line.
OILCHIEF ST · stainless-steel execution
DVZ lists a second execution of the same separator, the DVZ-FSU OILCHIEF ST, in stainless steel. Parts for the two are not assumed to be common, so the plate reading has to show which one is fitted. DVZ's current oily-water range shows only these two; a stores list naming another DVZ separator line is checked against the plate before it is quoted.
Reading a DVZ separator plate
DVZ-SERVICES GmbH of Syke, near Bremen, founded in 1981, builds sewage treatment plants (the BIOMASTER range) as well as the OILCHIEF oily water separator and the BILGMON 488 15 ppm bilge alarm — so a plate or stores list reading only DVZ does not say which system a part belongs to. On board, the unit type and serial number stamped on the separator's own plate are what identify the specific plant and its spare-parts range.
An OILCHIEF line and an Oilmaster line are read the same way, quoted differently
Both DVZ lines share the same coalescer-based principle, but the plate reading that opens each enquiry is not interchangeable between them.
OILCHIEF and Oilmaster are both bilge water treatment plants built around coalescers rather than centrifuges, and neither is answered from the plant name alone — the unit type and serial number stamped on the plate are what actually identify the machine. Where a type approval certificate is held aboard, sending it with the request settles questions a bare plate reading cannot.
Oilmaster carries a figure and a letter group after its name, and that group is the execution rather than decoration — a request built from the figure alone risks the wrong insert or monitor. OILCHIEF's own type marking works the same way: the insert and the monitor are what an inspection checks first on either line, so naming them alongside the plate reading keeps the request from bouncing back with a clarifying question.
What a DVZ line resolves to
Grouped by line, because OILCHIEF and Oilmaster are inspected the same way but do not draw on the same parts.
- Coalescer and filter inserts for OILCHIEF
- Oil content monitor parts and level probes for OILCHIEF
- Solenoid valves for OILCHIEF
- Inserts for Oilmaster
- BILGMON 488 bilge alarm parts, where DVZ's own monitor is fitted
- Gaskets and the automatic valve set for Oilmaster
- Complete overhaul kits by unit type and serial
The insert and the monitor are what an inspection checks first on either DVZ line — naming the unit type and serial before the rest of the list keeps a request from returning with a question.
Plate data that makes a DVZ enquiry quotable
The unit's own plate is the fastest route to a correct match. With the items below an enquiry can usually be priced in one pass; without them it comes back with a clarifying question first.
- Unit type as on the plate — DVZ-FSU OILCHIEF or OILCHIEF ST (stainless steel) — and whether the type-approved FSU by-pass function is fitted
- Serial number stamped on the plate
- Type approval certificate held aboard, where one applies
- Which items are needed, and the make and type of the 15 ppm bilge alarm fitted with the separator — DVZ's own is the BILGMON 488, but another make's monitor may be installed
- Photograph of the unit plate and of the part being requested
A monitor part and a filter insert are not answered alike
Requests naming DVZ separator components arrive mixed, and the review differs by what the line actually touches.
The bilge alarm and the valves that stop or divert discharge are what a survey or port state inspection exercises, and DVZ itself warns that many of its spare and wearing parts are adapted to the plant they are supplied for in ways not visible from outside, and that non-original parts can affect compliance and the validity of type approvals. These lines go to an OEM-route review by default.
Coalescer and filter inserts, gaskets and other size-and-material consumables are ordinary supply questions, and a verified alternative can be reviewed on them where a buyer's approval requirements allow, with dimensional and material documentation checked at RFQ stage. Vessel Core is an independent spare parts supplier and marks the proposed route against each line on the list, so a mixed request naming both kinds of item is answered by line, not as one blanket route.
DVZ separator parts — questions from the engine room
Which DVZ product lines come up most often in spare-parts requests?
The DVZ-FSU OILCHIEF oily water separator, in its standard and stainless-steel (ST) executions, together with DVZ's BILGMON 488 bilge alarm. DVZ also builds BIOMASTER sewage treatment plants, so a request reading only DVZ needs the plate to show which system it is; quoting from the unit type and serial number is what actually opens the enquiry.
What is the difference between OILCHIEF and OILCHIEF ST?
DVZ lists the OILCHIEF ST as a stainless-steel oily water separator alongside the standard DVZ-FSU OILCHIEF, which DVZ states is type-approved to IMO resolution MEPC.107(49). The plate reading is what tells them apart, so send it rather than the name alone; parts are not assumed to be common between the two.
What parts are ordered on a DVZ separator request?
Coalescer and filter inserts, oil content monitor parts, level probes and solenoid valves are the recurring lines on OILCHIEF; inserts, monitor cell and lamp items, gaskets and the automatic valve set on Oilmaster. The insert and the monitor are what an inspection looks at first on either line.
What should a DVZ separator spare-parts RFQ contain?
A workable request lists the unit type (OILCHIEF or Oilmaster with its full designation) and the serial number, plus the type approval certificate held aboard where one applies. A photograph of the unit plate and of the part being requested settles most of the remaining questions in one pass.
Can an alternative element be reviewed instead of the OEM part?
Only against the approval. An oily water separator is type-approved as an assembled arrangement, so a verified alternative is reviewed against the certificate reference rather than against the OILCHIEF or Oilmaster name alone. The oil content monitor and its cell, together with the solenoid and automatic valve set that govern discharge, are the items a type approval renewal is most likely to check, and these go to an OEM-route review by default.
Is Vessel Core connected to DVZ?
No, and there is no agreement of any kind. Vessel Core holds no dealership, distribution, representation or partnership agreement with DVZ, and quoting a component against the OILCHIEF or Oilmaster names implies no approval by the maker and no claim of interchangeability.
