Bachelors in Instrumentation & Control EngineeringBatch-2011From Vishwakarma Institute Of TechnologyPUNE - INDIA

My Journey of Dreams in Larsen & Toubro started on 27th August 2010when I got through the Campus InterviewsJoined L&T Hazira on 21st July 2011

Transferred to L&T Hydrocarbon IC Powai 24th August 2011

On 25th August 2011 I was offered transfer to L&T MFY Oman

Joined L&T MFY Oman on 27th November 2011

Prayag 2011PRAYAG was the best induction training I have been through so far.

It had lot of learnings and fun in package of a month.

We got introduced to all the Independent Companies(IC) that L&T owns.

The very first reaction after knowing span of L&T was I have got handful of Opportunities to groom myself in this Organization.

The Various small trainings which we been through during PRAYAGwere overwhelming our confidence to transform ourselves fromCollege Life to Professional Life and come out of unseen barriers.

The speakers were so enthusiastic about there ICs, which took usinto dilemma of which to choose, cause each IC had there ownlearning's.

The most important thing which PRAYAG gave us is Colleagues which we would have never met.

Joined the E&I Execution Department on 6th January 2012

Current Project Refurbishment Of ONGC Jack Up Rig SAGAR UDAY Sagar Uday is a ONGCs Oil Drilling Jack Up Rig.

Project was won by L&T FSBU.

L&T MFY OMAN was handed over this project for the construction.

Its was Built by Mazgaon Dock in 1990 in Mangalore Yard.

On 2nd July 2011 Sagar Uday was Docked at L&T MFY Jetty.

Jack Up Rig is in all an Offshore Huge drilling equipment which drills through the depths of ocean to explore OIL & GAS reserves.

Meggering and Contact resistance test was done for MCBsTotal MCB 257 Servicing and Overhauling of Lighting PanelsEmergency Shutdown System(ESD)Existing ESD system have to upgraded as one New Generator and other two equipments were installed which were to be linked with ESD.

ESD System was upgraded accordingly with CLIENT approvaland as built drawing was prepared by Vendor.

Functional Test of ESD was witnessed by ONGC.

Primary & Secondary Current Injection Test MCCB/ACB Test relay protection systems and their current transformers together.

Current level maintained though test circuit resistance may rise due to heating.

Built-in timer to record protection relay operation.

This Primary Current Injection Test Set is rugged, self-contained and designed for operation by one person, due to its portability.

The test set has a separate hand-held controller connected by an expandable cable. This allows the operator to work close to a protective relay while controlling a test. The maximum output current is 5000A - AC at line frequency. By changing the range switch, half the rated output can be obtained at twice the voltage.

Additionally, a separate auxiliary voltage output of 300 V, 2 A - AC or 125 V, 2 A - AC is available for testing voltage operated relay coils or checking the magnetization characteristics of current transformers. All outputs are fully variable and each test set has a nominal duty cycle when delivering full current and voltage. Continuous operation is possible at 40% of maximum current.

AOTC Visit14 No's of Jacking Motors & 4 No's of Anchor Winch motors Were sent to AOTC MUSCAT for overhauling.These motors were witnessed by Vendor ISPL and L&TFollowing Test were witnessed.


Cantilever Skidding OperationMicro switch are used for Brake Fail indication for Skidding MotorsThese switches were calibrated and functionally tested, as no failure indication should be raised while skidding operations.

Shutdown Valves7 numbers of new pneumatically operated shutdown valves are to be installed on salt water line.2 numbers of old shutdown valves were to be reused whichAre sent to AOTC MUSCAT for OverhaulingThese Shutdown valves are to be remotely operated from Tool Pusher & Control Room.

Existing Control Panels were to be reused for operation,For which old termination drawings were not available.Termination drawings for these drawings were prepared by myself.

Compressed air tapping's for operation of valves were identifiedAnd notified to piping department.

I am very much grateful to LARSEN & TOUBRO for trusting me andGiving such a overwhelming opportunityWhich will build my knowledge as an Engineer.

I promise to prove myself as a competent Employ to this OrganizationFor the upcoming years.

I am also thankful to my department colleagues for being supportive at every point of time


Thank You
