USCG advises for MARPOL deficiencies found on bilge alarm systems

During an inspection by the Marine Safety Detachment Port Canaveral Port State Control Officers, there were MARPOL deficiencies identified, related to the 15-ppm Bilge Alarm system of the Oily Water Separators (OWS) onboard four separate ships.

PSC FOCUS | 02/08/19

Specifically, the PSCOs discovered that the entries in the Oil Record Book (ORB) weren’t compliant to the Bilge Alarm Data being displayed by the bilge alarm, or also known as oil content meter.

[The Bahamas Maritime Authority has provided guidance on Oil Record Book keeping.]

Concerning the Bilge Alarm Data, it is required to record:

  1. date
  2. time
  3. alarm status
  4. the operating status of the 15-ppm Bilge Separator.

Moreover, the device is required to store the data for minimum of eight months, so that data is displayed or printed in a protocol for official system inspections as required by IMO Resolution MEPC.107(49)

In each case, the PSCOs issued a deficiency on the Port State Control Report of Inspection (Form B) requiring that each vessel needed to verify the validity of the entries in the Bilge Alarm data log against the entries in the ORB. Thus, the deficiencies were to be rectified to the satisfaction of Recognized Organization, Flag Administration, and the U.S. Coast Guard prior to the vessels’ departure from port.

Moreover, the monitor in this cases was the BilgMon 488 – as shown above –  model manufactured by Brannstrom, a Swedish company. The older model – see down below –  has a battery that is not replaceable by the crew inserted behind the circuit board of the Bilge Alarm.

The battery is used to maintain the stored data and Real Time Clock (RTC) when the unit is disconnected from a power supply. The system provides two contact points in which one can measure the battery voltage. In the four cases discussed, the USCG informs that the battery voltage was low and failed to provide the required 2.5 volts necessary to maintain the stored data without error.

As a result, when the data was viewed on the LCD screen it was scrambled and inaccurate.

According to the operators manualunder no circumstances should the battery be removed.

In light of the above, removing the battery may lead to an unrecoverable error, failure or data loss.

In the meantime, the newer model of Bilgmon 488, has a removable battery – as shown with the yellow arrow below -. Consequently, when the battery is ‘dead’ the cremembers can safely remove it.

USCG informs

To identify what model you may have note that the older type of master unit has serial numbers starting with “A,” “AE,” “BFA,” and “EDA.” The newer type of master unit has serial numbers starting with “4A,” “4AE,” “4BFA,” and “4EDA.”

Concluding, due to the discoveries above, the USCG recommends that ship owners and operators whose vessels use the BilgMon 488 to:

  1. Remind vessel engineers to routinely review the stored data available through the LCD display ensuring that the data matches the information recorded in the ORB and actual OWS operations.
  2. Maintain awareness that Port State Control Officers performing MARPOL examinations will verify that the BilgMon 488 is recording data properly and is aligned with the ORB entries. Avoid potential departure delays.

Concluding, ClassNK issued its annual PSC report, according to which there were 384 detentions recorded for year 2018.
