Overview
Every MARPOL Annex I discharge operation on a tanker depends on an ODME system that can measure oil content accurately across the full range of oil types the vessel will encounter — not just the clean petroleum products used in laboratory approval testing, but crude oil residues, petroleum product blends, and increasingly, bio-fuel components that are now present in the bilge and ballast water of vessels transitioning to alternative fuels. The difficulty for operators is that many ODME systems currently installed on trading tankers were developed and approved under regulatory standards that predate the bio-fuel measurement challenge. They were not designed for the composition of water that modern tanker bilge and ballast systems actually produce.
The Brannstrom CLEANTRACK 1000B is a Fourth Generation Oil Discharge Monitoring Equipment system, developed from a well-proven ODME concept and further evolved to meet the demands of current and near-future shipbuilding trends. It holds type approval to IMO Resolution MEPC 108(49) as amended by MEPC 240(65), with explicit acceptance for all bio-fuel blends as defined in IMO Resolution MEPC.1/Circ.761 — the IMO circular that defines the specific bio-fuel blend categories that ODME systems must be capable of measuring under current MARPOL requirements. That reference to MEPC.1/Circ.761 is a technical detail that distinguishes the CLEANTRACK 1000B’s approval from ODME systems that claim MEPC 240(65) coverage but do not specifically confirm compliance with the bio-fuel blend definitions of the associated circular.
What makes the CLEANTRACK 1000B stand out in a market where multiple ODME products claim equivalent approval is the fourth-generation product architecture combined with a “smart” measuring cell design that allows field replacement without specialist technician attendance. On a trading vessel where drydock intervals are measured in years and ODME maintenance has to be managed by the crew or a port service engineer rather than the original manufacturer, a system with a replaceable smart cell is the difference between a maintenance event that takes hours and one that requires the vessel to wait for a specialist engineer — or worse, operate with a degraded ODME while waiting for support.
Key Features
Fourth Generation ODME Architecture — Purpose-Built for Current Shipbuilding Standards
The CLEANTRACK 1000B represents the fourth generation of the Brannstrom ODME product line — not a regulatory update applied to an older platform, but a purpose-developed system designed around the monitoring and control requirements of vessels built or operating under current MARPOL standards. Fourth-generation development means the system’s software architecture, measurement processing, data logging, and integration interfaces reflect the vessel system design assumptions of current tanker construction — including modern cargo control systems, digital navigation integration, and the data retrieval formats that port state control inspectors now expect to examine. For operators specifying ODME on newbuilding projects or major vessel upgrades, a current-generation platform reduces integration complexity and future-proofs the installation against near-term regulatory and classification society documentation requirements.
MEPC 108(49) + MEPC 240(65) + MEPC.1/Circ.761 — Complete Bio-Fuel Approval
The CLEANTRACK 1000B’s type approval explicitly covers IMO Resolution MEPC 108(49), the amendment under MEPC 240(65), and acceptance for all bio-fuel blends as defined in IMO Resolution MEPC.1/Circ.761 — the circular that provides the technical definitions of bio-fuel blend categories that ODME systems must handle under current MARPOL requirements. This three-layer approval reference is more specific than simply claiming MEPC 240(65) coverage. MEPC.1/Circ.761 defines the actual composition categories of bio-fuel blends — including FAME, HVO, and other blend types — that the ODME must measure accurately. An explicit approval reference to this circular confirms that the type approval testing covered the specific bio-fuel compositions that current vessel operators are using, not a narrower subset of bio-fuel types that satisfied a less comprehensive interpretation of the MEPC 240(65) requirement.
Suitable for Crude Oils, Petroleum Products, and Bio-Fuel Blends — Full Oil Type Coverage
The CLEANTRACK 1000B is confirmed suitable for crude oils, petroleum products, and bio-fuel blends — the three primary categories of oil-contaminated water that tanker bilge and ballast systems produce. For a crude tanker whose ballast water contains crude oil residues, a product tanker whose bilge water includes refined product contamination, and a vessel operating on FAME or HVO-blended bunkers whose machinery space bilge water contains bio-fuel components, the same ODME installation provides accurate measurement across all three compositions without recalibration or measurement mode changes. That full-spectrum coverage means the operator does not need to manage an ODME approval gap as cargo type or fuel type changes across the vessel’s trading life.
Hazardous Area Installation Capability — Cargo Area Rated
The CLEANTRACK 1000B is confirmed suitable for installation in hazardous cargo areas — meaning the system is certified for use in the zone-classified spaces on tanker vessels where flammable vapours may be present. On crude tankers and product tankers, the ODME sample extraction point, detector installation, and associated wiring runs frequently pass through or are located within Zone 1 classified spaces including pump rooms and cargo area boundaries. An ODME confirmed for hazardous cargo area installation eliminates the design compromise required when a non-hazardous-area-rated ODME must be installed in a location that technically requires hazardous area-certified equipment — either the detector is located away from the optimal measurement point, or protective enclosures add bulk and maintenance burden to the installation.
Easy Replacement “Smart” Measuring Cell — Field Maintainable Design
The CLEANTRACK 1000B uses a “smart” measuring cell design that is specifically described as easy to replace in the field. The measuring cell is the component most exposed to the operational conditions that cause ODME degradation — contamination from oil films, solids deposition, and the cumulative effects of measuring oily water continuously over the vessel’s trading life. When a measuring cell requires replacement, a system with a field-replaceable smart cell means the replacement can be completed by a competent port service engineer or shipyard technician without specialist calibration equipment or manufacturer attendance. That field replaceability directly reduces maintenance downtime and the vessel’s dependence on manufacturer service scheduling — a material operational advantage for vessels operating away from major ports where specialist ODME service support is available at short notice.
Multiple Power Supply Options — 115/230VAC, 380/440VAC 3-Phase, or Air Supply
The CLEANTRACK 1000B supports power supply configurations covering 115/230VAC single phase, 380/440VAC three phase, and air supply — accommodating the electrical standards and available supply arrangements found across the range of commercial vessel types and ages where the system may be installed. Multiple power supply options are a practical consideration for retrofit installations where the available supply arrangement at the ODME installation point may not match a single-supply-only system’s requirement. The air supply option is particularly relevant for pump room installations on tankers where the provision of an electrical supply to a Zone 1 classified space involves additional wiring classification and protective measures — an air-powered option eliminates the electrical supply requirement at the installation point entirely.
LCD Display, USB Port, and Optional Printer — Flexible Data Retrieval
Discharge data is accessible directly via the LCD display for real-time monitoring during operations, downloadable via USB port for record transfer and ORB documentation support, and optionally printable via a connected printer for physical discharge record generation. The USB download capability is directly relevant for fleet management systems where ODME discharge data is transferred to shore-based compliance management software as part of the vessel’s MARPOL documentation programme. Having both real-time LCD display access and USB data download means the crew can monitor the discharge operation in progress and produce the documentation record afterward from the same device, without requiring a separate data management interface.
Optional Clean Water Connection — Discharge Start/Stop Management
The CLEANTRACK 1000B offers an optional clean water connection for discharge start/stop management — allowing the system to flush the sample path with clean water at the beginning and end of a discharge operation. This flushing capability ensures that residual oil from a previous sample does not affect the first measurement of a new discharge operation, and that the sample path is left in a clean condition after discharge ends. For tankers where discharge operations begin with water from tanks that may contain residual oil contamination from previous cargo operations, the clean water flushing option ensures the ODME’s initial readings represent the current discharge stream rather than residual contamination in the sample path.

Benefits
The most immediate operational benefit of the CLEANTRACK 1000B for tanker operators is that it closes the bio-fuel measurement gap that exists with older ODME installations — not just at the MEPC 240(65) headline level, but specifically across the bio-fuel blend compositions defined in MEPC.1/Circ.761. For operators whose vessels are transitioning to FAME blends, HVO, or other defined bio-fuel categories, the CLEANTRACK 1000B’s explicit Circ.761 coverage means the ODME type approval remains valid for the fuel types actually being used — not a general bio-fuel claim that may not cover the specific blend category on board.
The field-replaceable smart measuring cell reduces the maintenance lifecycle cost of the ODME installation significantly compared to systems requiring manufacturer attendance for cell replacement. Over the operational lifetime of a trading tanker, measuring cell condition is the primary source of ODME measurement degradation — a cell that can be replaced in the field by a port service engineer without specialist equipment means the vessel’s ODME can be maintained to measurement accuracy standard throughout its service life without dependence on manufacturer service scheduling or extended maintenance windows.
Multiple power supply options — including air supply — give the installation team genuine flexibility when fitting the CLEANTRACK 1000B into existing vessel electrical arrangements, particularly for pump room installations on tankers where the electrical supply arrangement in a Zone 1 classified space involves protective measures that add cost and complexity. The air supply option can eliminate the electrical supply requirement at the detector location entirely, simplifying the installation and reducing the associated electrical engineering scope.
For vessels where the ORB documentation programme includes electronic data transfer to shore-based compliance management systems, the USB data download capability provides the data extraction route without requiring proprietary software or manufacturer-supplied data management tools. USB download in a standard data format means the vessel’s MARPOL discharge records can be integrated into the operator’s existing fleet compliance management workflow without bespoke integration development.
Who It’s For
Technical Superintendents Managing Bio-Fuel Transition on Tanker Fleets
If you are managing a tanker fleet where vessels are progressively transitioning to bio-fuel blended bunkers — and where the existing ODME installations were approved only under MEPC 108(49) or hold MEPC 240(65) approval without explicit MEPC.1/Circ.761 bio-fuel blend coverage — the CLEANTRACK 1000B provides a replacement specification that closes the bio-fuel measurement gap with a documented approval reference that covers the specific blend categories your vessels will be using. When a flag state surveyor or PSC inspector examines the ODME type approval certificate against the bunker delivery notes showing bio-fuel blend composition, the CLEANTRACK 1000B’s Circ.761 reference gives you the approval documentation to confirm the equipment is correctly specified for the fuel actually on board.
Newbuilding Project Managers Specifying ODME for Modern Tanker Construction
For project managers specifying equipment on tanker newbuildings where the vessel will trade across a 20–25 year operational life during which bio-fuel use will become increasingly prevalent, and where the installed ODME must remain compliant through fuel type transitions without equipment replacement, specifying a fourth-generation system with explicit Circ.761 bio-fuel blend coverage and a field-maintainable smart cell design is a lower-lifecycle-cost procurement decision than specifying a system that meets today’s minimum compliance requirements but may require replacement as bio-fuel blend definitions and measurement requirements evolve. The CLEANTRACK 1000B is designed for the latest shipbuilding trends — which means it is the specification appropriate for vessels that will be trading in those conditions.
Chief Engineers on Tankers with Ageing ODME Installations
If you are operating with an ODME that was installed several years ago and is showing measurement accuracy degradation, producing inconsistent ppm readings, or generating maintenance calls that require manufacturer engineer attendance at inconvenient ports, the CLEANTRACK 1000B’s smart cell replacement design is the operational feature that directly addresses those maintenance problems. Being able to replace the measuring cell with a field-available replacement unit, without waiting for a specialist engineer from the original manufacturer, means you can restore the ODME to measurement standard during a routine port call rather than carrying a degraded system across multiple voyages while waiting for the right support to be available at the right port.
Possible Applications
Crude Tanker Ballast Discharge with Bio-Fuel Bunkers — Accurate oil content monitoring during ballast discharge on crude tankers operating on FAME or HVO-blended bunkers, where the ODME must measure crude oil residues in ballast water while operating with bio-fuel components present in the machinery space environment. MEPC.1/Circ.761 coverage confirms the measurement is valid for both the cargo oil residues and the bio-fuel environment.
Product Tanker Pump Room ODME Installation — Hazardous cargo area-rated installation in or adjacent to the pump room on product tankers, where the measurement location requires certified hazardous area equipment and the air supply power option eliminates the need for electrical supply into a Zone 1 classified space.
Tanker Fleet Bio-Fuel Transition ODME Upgrade Programme — Systematic ODME replacement across a tanker fleet transitioning to bio-fuel blended bunkers, where the replacement specification must cover all bio-fuel blend categories defined in MEPC.1/Circ.761 to maintain MARPOL compliance across the full bio-fuel transition.
Newbuilding ODME Specification — Future Bio-Fuel Ready — Fourth-generation ODME specification on tanker newbuildings where the installed system must remain compliant and field-maintainable across a multi-decade operational life that will involve progressive bio-fuel blend adoption.
High-PSC-Frequency Trading Route ODME Replacement — Replacement of ageing ODME installations on tankers trading Paris MOU, Tokyo MOU, or USCG high-inspection routes, where USB data download capability supports ORB documentation quality and the current type approval reference satisfies PSC approval status examination.
Remote-Trading Tankers Requiring Field-Maintainable ODME — Tankers trading routes where specialist ODME service support is not readily available at port calls, where the field-replaceable smart cell design ensures measuring cell maintenance can be completed by competent local engineers without manufacturer attendance.
Combination Carrier ODME for Mixed Oil and Bulk Operations — OBO and combination carrier installations covering the full crude oil and petroleum product range under MEPC 108(49) with bio-fuel blend coverage for the vessel’s bunker operation, in a single system suitable for hazardous area installation in the cargo pump arrangement.
Trust & Certifications
IMO Resolution MEPC 108(49) — Core MARPOL Annex I ODME Standard
MEPC 108(49) is the foundational IMO performance standard for Oil Discharge Monitoring Equipment under MARPOL Annex I Regulation 31, covering measurement accuracy across approved oil types, system response time, overboard valve control, and data recording requirements. Type approval to MEPC 108(49) is the mandatory certification for ODME installation on tankers under MARPOL and is the primary approval document examined by flag state surveyors and PSC inspectors when verifying ODME compliance. The CLEANTRACK 1000B holds full type approval to MEPC 108(49), providing the certification baseline required for ODME installation on all MARPOL Annex I regulated tanker vessels.
IMO Resolution MEPC 240(65) — Bio-Fuel Amendment
Resolution MEPC 240(65) amends MEPC 108(49) to address the measurement accuracy gap for bio-fuel blend compositions in bilge and ballast water. Mandatory from 1 January 2016 for vessels using bio-fuel blends, MEPC 240(65) approval confirms that the ODME’s measurement system handles the optical and chemical properties of bio-fuel contaminated water accurately — not just conventional petroleum product contamination. The CLEANTRACK 1000B is type-approved under MEPC 240(65), maintaining MARPOL compliance for vessels transitioning to bio-fuel operation.
MEPC.1/Circ.761 — Bio-Fuel Blend Category Definitions
IMO Circular MEPC.1/Circ.761 provides the technical definitions of the bio-fuel blend categories that ODME systems must be capable of measuring under current MARPOL requirements — including FAME, HVO, and other defined blend types. Explicit type approval coverage referencing MEPC.1/Circ.761 confirms that the CLEANTRACK 1000B was tested against the specific bio-fuel compositions defined in this circular, not a general bio-fuel claim without reference to the composition categories. This distinction is increasingly relevant as flag state surveyors and PSC inspectors examine ODME type approval certificates for bio-fuel coverage specificity, particularly on vessels where bunker delivery notes confirm bio-fuel blend composition that must be covered by the installed ODME’s type approval.
Brannstrom Sweden — Marine ODME Development Heritage
Brannstrom Sweden is the developer of the CLEANTRACK ODME product line, with the 1000B representing the fourth generation of a system concept with a documented development history across successive IMO regulatory updates. The CLEANTRACK product series has an established installation base in the tanker segment, with each generation developed to address the compliance and operational requirements of the current regulatory and shipbuilding environment. For procurement teams evaluating ODME suppliers, a manufacturer with a four-generation product development history and a documented track record of maintaining type approval currency across MARPOL regulatory amendments provides a supplier relationship with demonstrated commitment to the ODME product category over time.
Accessories & Variants
Optional Printer — Physical Discharge Record Generation
An optional printer connection is available for the CLEANTRACK 1000B, allowing printed discharge records to be generated directly from the unit during and after discharge operations. Printed records support Oil Record Book Part II entries and provide a physical documentation trail for PSC examination. For vessels where the ORB documentation process relies on printed records rather than or in addition to digital ORB software, the optional printer eliminates the need for manual record transcription from the LCD display.
Optional Clean Water Connection — Discharge Start/Stop Flushing
The optional clean water connection allows the sample path to be flushed with clean water at the start and end of discharge operations — ensuring that the first measurement of a new discharge reflects the current sample rather than residual oil from the previous operation, and that the system is left in a clean condition after discharge ends. For vessels where the ballast or bilge water discharge sequence involves multiple tanks with varying oil content, the clean water flushing option improves measurement validity at discharge transitions.
Pump Model Selection — Flow Rate Configuration
The CLEANTRACK 1000B sample flow rate ranges from 240 to 900 litres per hour depending on the pump model selected. The correct pump model should be specified based on the vessel’s discharge piping arrangement, the sample extraction pressure, and the required sample flow rate for the measurement cell configuration. Confirm the appropriate pump model with your supplier at the time of procurement to ensure the installed flow rate matches the measurement cell’s optimal operating range.
Available Variant
