Removal of TD Fuel pump.

(i) Removal of TD fuel pumps.

(ii) Post de-gutting/ removal of pipelines, blanking of the associated system pipelines to be undertaken to maintain system integrity (blanks are to be provided by the firm). Also, any damage while de-gutting has to be rectified by the firm upto Ship Staff satisfaction in stipulated time without any charges.

(iii) Decoupling of turbine assembly from fuel pump and removal of the unit including gear box to be undertaken.

(iv) Post removal of turbine and RG assembly from foundation shifting of turbine and gear box assembly from EBR to Jetty through designated route (soft patch/hangar) to be undertaken.

MD Fuel Pump.

(i) Shifting of MD fuel pump and electric motor from Jetty to respective location to be undertaken. The shipping-in route of proposed electric motor is same as shipping- out route. The proposed motor being small in size can be shifted in assembled condition

(ii) Fitment of electric motor with frame and securing of supporting frames on foundation using SV mounts.

(iii) Layout of cables from junction box to motor and connect cables from starter to electric motor to be undertaken by firm. Cable glands and trays of the existing Log system will be re-utilized for the cabling of proposed MD pumps.

(iv) Piping/ cable schedule will follow the existing system cables. Supply from the existing JBs to the Starters and from the starters to the Motors will be routed through existing cable routes. However, minor augmentation of the frame will be required to accommodate the three core cables.

(v) In-situ gauging, manufacturing and fitment of instrumentation and fuel pipelines along with associated components (unions and flanges) to be undertaken by firm

(vi) Pressure testing of all fabricated pipes upto pressure indicated above has to be undertaken in presence of NSRY(Kar) QC team/ SS reps. Pressure testing would be finally cleared by NSRY(Kar) QC team.

(vii) Welding of pipes/ frames on board, if required to be undertaken by certified and skilled welders. DPT of welds to be undertaken in presence of NSRY(Kar) QC team and SS reps.

Trials and STW

Trials of MD fuel pump will be undertaken post system integrity checks. Trial mainly entails performance checks of the pump including parameters checks (suction/ discharge pressure), vibration trial, insulation/ SPM checks on motor, motor starting and running current checks etc. in presence of OEM.
