Cochin Shipyard Completes MODU Repair The repair and upgrade of Sagar Vijay MODU was the largest job ever completed by India's Cochin shipyard. India's Cochin Shipyard recently completed major repairs and upgrading of Oil and Natural Gas Corp. of India's Mobile Offshore Drilling Unit (MODU) Sagar Vijay. The project was the largest ever single repair project undertaken by the yard. The total work package consisted of cyclone damage repairs and an upgrading and enhancement of the capability of the vessel for deep- water drilling, in addition to major routine repairs. Sagar Vijay was built in 1984 by Hitachi Zosen. The unit suffered serious damage during a cyclone in 1996 while carrying out explorato- ry drilling operations in Bombay High. When the MODU arrived at Cochin, almost all major machin- ery had to be opened and inspected Drew Marine Provides For Repairs On The Go The Amerarc L-300 inverter arc welding machine from Ashland Chemical Company's Drew Marine Division is designed to efficiently handle typical shipboard repair and maintenance tasks. The unit offers advanced features for TIG welding, and both the LS-300 and LT-300 models are suitable for stick welding, and for TIG welding in the lift-start mode. Inverter technology provides safeguards against improper operation or abuse through short circuit, and overload protection and other elec- tronic controls help maximize the reliability of the machines.

The inspections found that major systems in need of repair included drilling equipment, riser handling, riser holding and support arrange- ment, compressed air, anchor han- dling and various subsea equip- ment systems. It was while Sagar Vijay was laid-up that the owner made the decision to enhance the vessel for deepwater drilling. The upgrading work involved extending the anchor cable length and increasing the length of the riser pipes and control cables; the provision of additional riser ten- sioners; the modification of the riser layout; the installation of additional mud pump, compressors and ventilation system; and the renewal of the subsea equipment control system. The entire upgrade cost approximately $13.2 million. When completed, steel work totaled more than 250 tons, and the vessel had been drydocked for 41 days. Circle 62 on Reader Service Card HAPS FREE!
