JOWA CLEANTOIL 9000 is a critical Oil Discharge Monitoring Equipment (ODME) system designed to ensure maritime compliance with MARPOL regulations regarding the discharge of oily water from tanker cargo areas. System Overview & Purpose

The CLEANTOIL 9000 functions as an automated supervisor for overboard discharges. It continuously measures the oil content in ballast water and slop tank discharges, calculating the "instantaneous rate of oil discharge" (liters per nautical mile) to ensure it stays within legal limits (typically 30 L/nm). Key Technical Components According to technical documentation found on , the system consists of: Computer Unit:

Usually installed in the Cargo Control Room (CCR) to process data and record discharge logs. Analyzer Unit:

Contains the oil content meter, measuring oil concentration in PPM (Parts Per Million). Flow Meter & Log Transmitter:

Provides input on the total discharge flow rate and ship's speed, essential for calculating the discharge rate. Overboard Discharge Valve Control:

An automated safety mechanism that shuts the valve if oil levels exceed limits. Operational Procedures

The manual outlines specific steps for system testing and operation: System Startup:

Change the operation mode from Auto to Manual (MAN) for testing. Input Simulation: Set flow rates (e.g., ) and ship speed (e.g., ) to verify calculations. Oil Content Calibration: Adjust the PPM settings. When the oil content is set to

(at standard flow), the system should trigger an alarm and automatically close the overboard valve. Maintenance & Troubleshooting

Effective maintenance is required to prevent "abnormal sample water pressure" alarms or sensor failures. Manual Cleaning:

While some JOWA models feature self-cleaning, the 9000 series manual provides specific instructions for manual sensor cleaning and resetting persistent alarms. Cable Checks:

Standard troubleshooting involves measuring voltages at specific points if an alarm remains after checking primary causes like blocked filters.

The JOWA Cleantoil 9000 is an Oil Discharge Monitoring and Control System (ODME) designed to ensure oil tankers comply with MARPOL regulations by monitoring the oil content of ballast and bilge water before discharge. Core System Components

The system is divided into modules to handle different environments on the ship:

Computer Unit: Installed in the Cargo Control Room (CCR); it processes data, controls other components, and logs all discharge operations for regulatory reporting.

Converting Unit: Located in the engine room, it converts electrical signals from the computer into pneumatic or electrical supply signals for the analyzing unit.

Analyzing Unit: Situated near the sampling point in a hazardous area, it contains the oil content meter, a sample feed pump, a fresh water valve for cleaning, and a pressure transmitter. Standard Operation Guide

Before starting any discharge, perform these essential pre-checks:

Valve Lineup: Ensure inlet and outlet valves for the flow meter and sample line are open.

Supplies: Verify fresh water supply and air supply (~6 bar) for pneumatic valves are available.

Mechanical Check: Manually rotate the sample pump shaft to ensure it moves freely.

Cleaning Solution: Check that the cleaning solution container is filled; the system features a unique self-cleaning function to minimize manual maintenance.

Initialization: Start the system from the computer unit. Confirm the overboard discharge valve opens only after the system stabilizes (typically about 1 minute after startup). Calibration and Testing

Measuring Range: The system monitors oil content from 0 to 1000 PPM.

Simulation Mode: To verify alarms, you can manually set flow rates and speeds (e.g., 1000 cu.m/hr at 10 knots) to confirm the system triggers an alarm and closes the overboard valve if the oil content exceeds 300 PPM.

Alarm Troubleshooting: If alarms persist, check for abnormal sample water pressure or measure cable voltages as specified in the manual's troubleshooting section. Finding the Manual

If you hear cavitation (a grinding noise from the pump) or experience low flow, the manual’s hydraulic diagram helps you trace the pressure drop back to a clogged inlet filter or a closed valve.

A: Section 5.2 of the manual explains: Green zone (0-3 Bar) = OK. Yellow zone (3-5 Bar) = Change filter soon. Red zone (>5 Bar) = Change filter immediately. If the gauge hits 6 Bar, the bypass valve opens, sending dirty oil downstream.
