Nantong COSCO Shipyard, China: Repair work for Collision damage of MV “ AENEAS” 82,000 bulk carrier, TMA.
MV “ AENEAS” 82,000 Dwt bulk carrier vessel owned by TMA was undergone a collision with another container vessel at Shanghai pilotage on 2nd April. The vessel’s bow part (port side) was heavily damaged. After preliminary damage assessment at Shanghai the vessel was brought to COSCO Nantong Yard for the repair work. SMC was asked to do the Repair work assessment and the entire repair work supervision at the yard. Since no floating dock was available at Yard during that time and due to the urgency in carrying out the repair work it was decided to carry out floating repair work with trimming the vessel by aft. The repair assessment was carried out by SMC supervisor and DNV surveyor and the repair plan was finalized and accepted by the Class society. Damage was occurred on shell plate, web frames and stringers in way of fore peak tank, Void space and No.1 cargo hold(port). The vessel was Korean built and hence the lines plan for the hull form was not readily available and offsets for the double curvature shell plate was taken from the non-damaged starboard side shell plate using hanging platforms.
New shell plates were cut and formed and internal members were fabricated and the repair work was carried out successfully and timely by using a combination of hanging platform, floating crane and barge. All the NDT work(UT and RT) and air test were carried successfully and handed over to painting department for the coating work. Work was on-going in two shifts 24 hours during the last one week.
The repair work was completed on 28th April and the vessel sailed out on 29th April. The total steel weight renewed was estimated as approx. 57 tons
