in good condition.

In order to get the system complete operational, we will require to renew all

the faulty items and must be addressed by maker before delivering to the

vessel.

Remark: We were unable to test the following 09 no’s sensors due to time

constrain and also located very high. There was no access. Had inform supt

regarding this.

B04, B05, D05, D06 and D07 – Located above M/E

D08, D09, D10 and D11 – Located above no 1, 2 and 3 generator

CC) Cargo Bilge Alarm System

Attended the vessel and check and test the cargo hold bilge level alarm system

as requested by supt. Total there are 6 cargo hold. Cargo hold 2 to 6 consist of

2 no’s bilge sensor each and cargo hold no 1 only consist of 1 bilge sensor.

There is also 2 no’s bilge sensor located at bow thruster room. So total there

are 13 no’s bilge level sensor in the system. Picture below indicating the

monitor of the system.

Page 7 of 16

All bilge sensor alarm is indicated on the computer monitor in engine control

room as in picture above.

We tested all the 13 no’s bilge sensor and found as follows

-In bow thruster room, tested both the fwd and aft bilge sensor and found

satisfactory.

-Cargo hold no.1 to no.6, total 11 no’s all found in very bad condition. Now

working.

Informed the supt. and requested all the following 11 no’s bilge sensor must

be renewed in order to get the system up and running.

NOTE: The system was then tested and simulated from the IS barrier to

confirm that the loop was working satisfactory and only sensor require

renewal.

Picture above indication the condition of most of the cargo hold bilge level

sensors.

ADDITIONAL JOB TO RENEW ALL BILGE LEVEL SENSORS AFTER CONFIRMATION

BY SUPT.

As requested and confirmed by attending supt. To renew all the faulty cargo

hold bilge alarm sensors. We proceed with the order and upon receiving the

new bilge alarm sensors, we carried out the renewal job accordingly at

anchorage.

Page 9 of 16

Since the bilge level sensors was in very bad condition, we had to knock out all

the bolt, drill and re-tap the bolt thread. Renew the bolts and also gaskets.

Finally we manage to renew all the faulty cargo hold bilge level sensor

accordingly and connect and secure the cables properly.

Supt had ordered total of 13 no’s bilge level sensors. Total 11 no’s had been

renewed for cargo hold and 2 no’s to supply as ship spare.

As picture beside indicating all the faulty

sensors was replaced and brought on top the

deck. All was found in poor condition.

Page 10 of 16

Finally the cargo hold bilge level alarm system was tested after renewal and

found in satisfactory condition. Ch engineer and second engineer was satisfied

with the system.

DD) Fuel Oil Flow Meters

As requested by supt to remove and bring out the fuel oil flow meters for

shore calibration on URGENT basis. Therefore the following flow meters were

remove and brought back to shore. The removed pipes was blanked with

flanges as requested and for safety reason.

- M/E Fuel Oil Flow Meter 01 unit

Make: NITTO

Serial no: 0166978

- G/E Fuel Oil Flow Meter 01 unit

Make: NITTO

Serial no: 0166979

- CONTOIL Flow Meter 01 unit

Serial no: 4668294

Picture below indicating the removal of flow meters locate inside purifier room

Page 11 of 16

The 3 no’s flow meters was calibrated and obtained meter factor accordingly.

Finally the flow meters was delivered on board and installed. After running for

1 day during vessel shifting to anchorage, second engineer complained that the

G/E fuel oil flow meter was not working. Therefore, when we attended the

vessel at anchorage, we opened up dismantled the counter assembly to

investigate the fault.

The counter assembly was removed from

the flow meter to investigate on the fault

complained.

We then dismantle the magnetic

gear shaft and found it was jammed

due to some small particle found

stuck inside. So we dismantle the

complete piece, serviced and

assemble back to original. Then installed back and tested to satisfactory. Ch

engineer and 2nd engineer was satisfied.

Finally all the flow meters was tested and found in satisfactory and ready for

operation.

EE) Installation of New Fuel Oil Leakage Alarm system

As discuss with supt. on board the vessel, we are requested to design, supply

and install a new fuel oil leakage alarm system on the existing fuel oil leakage

line located in the engine room platform. So we discussed, sketch a drawing

and agreed by supt that we will design according to drawing.

Upon confirmation, we start the fabrication of new oil tank with one inlet on

top, one outlet return line, one testing oil inlet on top of the tank and a

horizontal float installed to the tank. Picture below indicating the newly

fabricated oil tank.

Testing with oil inlet Oil leakage inlet

Outlet return line

We also installed a valve on the inlet line to oil tank and outlet return line as

requested by ch engineer.

So as requested by supt. we start to remove the main fuel oil leakage pipe

which was about 350mm diameter, and transport to the engine room

workshop where the hot works can take place. See picture below

Page 13 of 16

After dismantling the big pipe and lifting it down, we transported the pipe to

the engine room workshop. There, the ship crew assisted us in the hot works.

We cut the socket out and welded a 2 inch

pipe elbow pipe with a flange connection.

Page 14 of 16

After hot works completed, we transport back the big pipe to its original

location and fit in place so that we can start to fabricate the 2 inch pipe from

the flange connection to the new oil tank.

Newly fabricated 2 inch pipe new oil tank

After all pipe fabrication, we installed the

magnetic float switch and connected the

cable which we had run from engine

control room console to the engine room

bottom platform at the newly oil tank.

We also fabricated a new alarm panel with two alarm points (one as spare).

The alarm panel was installed on top of the engine room console as agreed by

ch engineer and supt. See picture below.

Newly fabricated alarm panel with two alarm points

We also run cable from the new alarm panel in engine control room to the

outside of engine control room where we had installed an external

audio/visual upon request. See picture below

Page 16 of 16

Finally upon completion, we tested the complete system with the presence of

ch engineer and second engineer by actually filling the new oil tank with oil.

The alarm activated accordingly and they also checked on the audio/visual

alarm locate outside engine control room. The sound was loud enough and can

be heard clearly in engine room. The system is found satisfactory and accepted

by ch engineer.
