This Barge LTS 3000 is being used by LTHE for installation of ONGC’s Cluster 8 jacket # D-30-2, 4 legged at Mumbai High. While lifting and lowering the Jacket in water it was dropped with crane boom collapsing.

It is reported that LTS 3000 CRANE BOOM fell like bullets on main deck and nearby area. Main hoist, apparently brake failure. Wire broke into pieces along with few structure parts.

LTS3000 is a first Indian flag, dual class (ABS & IRS) self-propelled offshore construction vessel built at ASL Shipyard, Singapore (Hull built in China).

Vessel is fitted with NOV Amclyde’s ‘PC-42 HVY’ fully revolving main crane having maximum lift capacity of 3000ST. The crane has 82 meter long boom. The main hook is capable of lifting 3000ST at 27 meter radius.

Going back on history of Barge LTS 3000, this vessel is jointly owned by L&T and Sapura as 60:40. During construction of this vessel, L&T insisted on buying the crane from source, what was installed in Sapura 3000 (Sapura’s other Vessel). It was said that Sapura was not happy with this decision but but that L&T did not take this into consideration. During MHN installation they were just lucky, wire came out of the drum, then it was replaced. Current flux causing all fuse burnt problem, right from the inception issues with the crane, major incident was waiting to happen.

LTHE is handling the installation campaign on their own without Sapura. The HLV is believed to be taken by LTHE on bare-boat charter from L&T – SAPURA JV (LTS) and Operations including Manning is by LTHE.

The Project is ONGC’s Cluster 8 Development, scope being:

  • Four Wellhead Platforms (B192-5A Bridge connected to existing B192-5, B192-10, D-30-2 and WO24-3) in water depth range 60 ~ 70 m
  • Clamp-on at B192-1
  • 9 segments of pipelines x 76 Kms,.
  • Associated modifications

LTHE was awarded this EPIC Contracts at approxi. US$ 223.29 million. Completion schedule is Platforms by May 2020 and rest of scope/final completion by Jan 2021.
This Jacket, D-30-2 is the first one to be taken up for Installation.

On March 11, 2020 night (Early hours of March 12, 2020), there were reports mentioning:

  • All PAX other than Marine crew were asked to evacuate the vessel
  • Jacket (floating in water) is constantly hitting the hull of LTS 3000.
