Case studies

Further to  the breaking of the cold water pipe at  Ambatovy Nickel plant, the SEANERGY OI team conducted the following steps:

• Cutting, disconnection and lifting the old section (300 m, 330 tons)
• Launching of the new section, implementation of lift bags
• Casting of new section and connection to the rest of the pipe despite significant swell conditions through an innovative procedure established by SEANERGY OI.BE (engineering design department)

• 8 hookah diving equipment
• 50 MBU 5 t (soft shell)
• Tug, Diving Support

Unprecedented operation. Ambatovy significant gains in terms of costs with the introduction of light resources, compared to a conventional solution which would have required substantial marine resources.
