THE TOPSIDES destined for Chevron's North Nemba field in block 67 off Angola are stranded in Indonesian waters after a heavy lift vessel transporting the facilities capsized. Five of the 20 crew on board are missing presumed dead off Singkep Island, which lies south of Bintan in Indonesia's Riau province. Five personnel were injured in the mishap. Four were airlifted immediately to Singapore, while the fifth was less seriously hurt and was expected to make the same trip on Thursday.
