Overview
Every time the Graviner MK6 oil mist detector system registers an alarm event, a channel reading, a system fault, or a user interaction, that event is written to the memory on the main PCB. This event log is not a convenience feature — it is the documented record of everything the crankcase protection system has experienced during its service life on board. It supports maintenance investigations, insurance claims, flag state incident reporting, and class survey documentation. But the memory that stores this record has a finite capacity. When the main PCB event log memory reaches its limit, the system requires a memory component replacement to continue logging — and that replacement component is the EEPROM or EPROM fitted to the MK6 main PCB.
The Graviner MK6 EEPROM (Part No. 44782-K182) and EPROM (Part No. P57100-113) are the OEM-referenced memory replacement components for the Graviner MK6 oil mist detector main PCB. The EEPROM 44782-K182 is replaced when the main PCB event log memory is full — restoring the MK6 system’s ability to continue recording system events, alarms, and operational data. The EPROM P57100-113 is the program memory component for the MK6 main PCB, carrying the firmware that governs the system’s detection logic and operational behaviour.
What makes these OEM-referenced memory components the correct choice for MK6 memory maintenance is straightforward: memory components are firmware- and hardware-specific. A non-OEM EEPROM or EPROM of the same physical format may appear compatible but carry incorrect memory addressing, incompatible data structure formatting, or mismatched firmware — any of which can result in a system that appears to function but is not logging correctly, or worse, is not detecting correctly. The Graviner part references 44782-K182 and P57100-113 confirm the components are the manufacturer’s own memory specifications for the MK6 main PCB — the only safe choice for safety-critical memory replacement on a SOLAS crankcase protection system.
Key Features
EEPROM 44782-K182 — Event Log Memory Replacement When Main PCB Memory Is Full
The EEPROM (Electrically Erasable Programmable Read-Only Memory) component 44782-K182 is the data storage memory on the Graviner MK6 main PCB that holds the system event log — the recorded history of alarms, channel readings, fault conditions, and system interactions accumulated over the MK6 system’s service life on board. When this memory reaches capacity, the MK6 system can no longer write new events to the log. Replacing the EEPROM with the 44782-K182 restores the event logging function — allowing the system to continue building the documented operational record that maintenance engineers, surveyors, and incident investigators rely on.
EPROM P57100-113 — Program Memory Carrying MK6 System Firmware
The EPROM (Erasable Programmable Read-Only Memory) component P57100-113 carries the firmware program that governs the Graviner MK6 system’s detection logic, alarm threshold processing, channel management, and communication protocols. Unlike the EEPROM which stores accumulated event data, the EPROM stores the fixed program instructions that tell the MK6 system how to operate. EPROM replacement is required when the program memory component fails, becomes corrupted, or requires a firmware update to address a known issue. Using the OEM-referenced P57100-113 ensures the replacement EPROM carries the correct MK6 firmware specification — not a generic or mismatched program memory.
OEM Part References — 44782-K182 and P57100-113
Both components are supplied under Graviner manufacturer part references — 44782-K182 for the EEPROM and P57100-113 for the EPROM. For a safety-critical application like crankcase explosion protection memory, OEM part reference sourcing is the only appropriate standard. Memory components sourced against manufacturer part numbers carry the specification assurance that confirms correct data structure compatibility, firmware version accuracy, and PCB interface compatibility — none of which can be confirmed for non-OEM memory components sourced by physical format alone.
PCB Blank 39862-K152 — Confirmed Main PCB Association
The image of the 44782-K182 component shows it mounted on the PCB Blank 39862-K152, Rev 1 — the specific MK6 main PCB board with which these memory components are associated. For marine engineers and procurement teams confirming component compatibility before ordering, the PCB blank reference provides an additional cross-check point to confirm the EEPROM and EPROM part numbers are correct for the specific MK6 main PCB revision installed on board.
Available in New and Refurbished Condition
Both the EEPROM 44782-K182 and EPROM P57100-113 are available in new and refurbished condition. New condition components provide factory-specification supply with full remaining service life. Refurbished condition — inspected and verified before supply — offers a cost-effective and often more readily available option for vessels where the age of the MK6 installation and procurement budget considerations make a tested refurbished component the practical choice. Contact Alright Engineering Solutions to confirm current stock availability for each condition and part number.

Benefits
Restores the MK6 event logging function when main PCB memory is full. A Graviner MK6 system with a full EEPROM is a system that has stopped building its own maintenance and incident record. Replacing the 44782-K182 EEPROM restores the event logging function — ensuring the system continues to document every alarm, every channel reading, and every fault condition from the point of replacement onward. For vessels where the MK6 event log is part of the planned maintenance system documentation, this is not an optional restoration — it is a required maintenance action.
OEM firmware in the EPROM means the MK6 system behaves exactly as designed. Replacing the EPROM P57100-113 with the manufacturer-referenced component ensures the MK6 system continues to operate with the correct detection logic, alarm threshold processing, and communication behaviour. A non-OEM or mismatched EPROM introduces the risk of incorrect system behaviour that may not be immediately obvious — but could result in missed alarms or incorrect threshold responses in a real crankcase oil mist event.
Preserves the investment in the existing MK6 main PCB. A full EEPROM or failed EPROM is a component-level failure on the MK6 main PCB — not an indication that the entire main PCB assembly needs to be replaced. Memory component replacement at the 44782-K182 or P57100-113 level addresses the specific fault at component cost, preserving the fully functional PCB assembly and avoiding the significantly higher cost of a complete main PCB replacement.
Supports ISM Code maintenance documentation standards. Sourcing and recording memory component replacements against Graviner OEM part numbers — 44782-K182 and P57100-113 — in the vessel’s planned maintenance system provides a clean, auditable maintenance record. For vessels audited against ISM Code safety management system standards, maintenance records that reference OEM part numbers are the expected documentation standard for safety-critical equipment.
New and refurbished options provide procurement flexibility across different vessel situations. Whether the vessel requires factory-new components for a newly commissioned MK6 installation or tested refurbished components for a long-service system where cost and availability are primary procurement considerations, both options are available — ensuring the correct component can be sourced against the specific requirements of the situation.
Who It’s For
The Chief Engineer or Second Engineer Managing MK6 Memory Capacity on Board
The MK6 system has flagged that the main PCB event log memory is full — or you have been advised during a service visit that the EEPROM is approaching capacity. You need to source the correct replacement EEPROM — the 44782-K182 — to restore the event logging function before the next class survey, where an inability to demonstrate current event logging capability could generate a survey observation. You also want to confirm the correct part number against your MK6 main PCB revision before ordering, to avoid receiving an incompatible component.
The Marine Equipment Service Engineer or Graviner Service Technician
You service Graviner MK6 systems regularly on vessels at port and during drydocking periods. EEPROM memory capacity issues and EPROM failures are component-level faults you encounter on long-service MK6 installations — often identified during a routine service visit rather than reported as an on-board fault. Having the 44782-K182 and P57100-113 in your service stock allows you to carry out the memory component replacement during the same service visit, rather than requiring a return visit once the spare has been procured.
The Fleet Technical Superintendent Managing Long-Service MK6 Installations
You manage a fleet with Graviner MK6 systems that have been in continuous service for a decade or more on several vessels. EEPROM memory capacity is a predictable maintenance item on long-service MK6 installations — systems that have been accumulating event log data since original installation will eventually reach memory capacity. Provisioning 44782-K182 EEPROM components as planned maintenance spares on your longest-service MK6 vessels is the proactive step that keeps event logging operational without a reactive scramble when memory capacity is flagged during a survey or service visit.
Possible Applications
- MK6 event log memory restoration after EEPROM capacity reached — EEPROM 44782-K182 replacement on long-service MK6 installations where the main PCB event log memory has reached its storage capacity and can no longer record new system events
