Hazira Ph1 C2 terminal
Since I was the project manager for tank farm at Hazira, the implementation of this Ethylene terminal was entrusted to me with PBMR and Charles D'Souza as my counterpart in construction. The turn key contract was awarded to L&T and LGA. The corresponding leaders were A S Deshmukh and Hugo Baumgartner. My team was SK Sharma, Manpreet Singh, AVN Murthy and SM Pathak. PBMR had the services of Sai,Kanniah, Anantha Narayan for execution and AJ Vyas for inspection. Hugo was supported by M/S Boltze, Shulte, Hermann. ASD had the back-up of L&T stalwarts -AM Naik, S Venkatramanan, Bhambani, VP Bajaj, Dakras, MR Shankar. In his project team he had Arvind Kumar, Fernandez, Dani, Shette, and many juniors. As that was the first turn key project to L&T GroupII in India, the complete focus was there in the execution but at the same time inexperience and lack of exposure in project implementation showed off.
Fortunately they left the tank design to LGA and VTV- that time Mr Raghavan,MD was personally involved in the design with Mr Shulte of LGA and they took complete care. When it came to civil, the project group left that aspect to ECC- that time a group company of L&T, and Mr HM Desai oversaw thecomplete task right from design stage. The team arrived at cost effective solution of selecting 9%Ni plate for inner shell of the double walled tank with only three layers of outer shell with 9% Ni and the rest killed carbon steel and outer blast proof concrete wall. Without going through any argument or check , we .struck to shell height of 20M high, the national statutte for tank height. Even on date, the debate is still on in design circles, whether that tank design will fall under single integrity or double integrity factor!! But the tanks are still in stable operation for the last 25 years. Also the project team selected in-tank submersible pumps from M/S Ebara. These decisions were arrived at to minimise the nozzles at shell side of the tanks.With enough back ground experience, Mr Shulte recommended to engineering to raise the tank pad by 1.2 M from grade level and make reinforced concrete pillars to rest the pad bottom. This he explained to us , such an arrangement will facilitate enough air circulation and will prevent the cryogenic cold temperature to go to mother earth. Of course the perlite insulation between the two shells was the obvious choice and turn key order was placed on a party from Ahmedabad . Mr Shreyas took complete charge and implemented. In those days M/S John Zink was the sole supplier of flare system and Mr Thiruwadi took care of the same.
When it came to fabricated equipments like drums,exchanger etc. typical of L&T they classified them into A,B,C category and sub ordered the B&C items on parties like Mistry Prabudas. There the trouble started. Though LGA was impressing L&T at every stage implying that ethylene in cryogenic state is a different animal and enough and due care has to be taken when choosing the tubes for exchanger in terms of metallurgy and tube sheet thickness and surface area calculation etc. L&T did not realise the seriousness of them. Mr PD Samant, head of exchanger design in L&T became a silent spectator and his voice was not heard by L&T top management. That made my life miserable and I had to pay a heavy price in my career growth!
Similarly , since no one other than LGA had any exposure in Detailed engineering of cryogenic state C2 transfer line, the issue cropped up for pipe supports and cold insulation. L&T identified M/S Swastik Engineers for pipe supports and M/S Lyoyd Insulation for cryogenic pipes insulation.
