M/V “Lysblink” “Lysvik” and “Lysbris”

Ship lenghtening

The vessel LYSBLINK was built according to the rules and regulations of Det Norske Veritas (DNV) in AGB Shipyard in Surat, India, in 1998, as a paper carrier with the side-door loading system. The ship with two decks, one cargo hold, the engine room and the superstructure at the stern section, also designed for carrying containers on the main deck and on the tweendeck as well as on the inner bottom.

The main dimensions:

Scope of conversion works

  • lengthening of the ship after the hull cutting and placing an insert of 27,10 m long ,
  • strengthening of the existing double bottom,
  • installation of additional container sockets on the main deck, on the tweendeck and on the inner bottom including installation of strengthening under the sockets,
  • extension of the existing piping lines and of the electric wirings,
  • enlarging of the existing CO2 room at the bow section,
  • separation of wing tanks at bow section of cargo hold.

The ship’s lengthening operation was carried out with the use of a special equipment and instrumentation such as the rails, heavy lift trolleys, sliding rails, Teflon plates, frames and the floating pontoon. Prior to docking the vessel, the 600 mm sliding beams were laid on the keel-blocks foundations (for traction), on which the 370 mm high frames were set-up with 30mm wooden cushions on top of them. After the vessel was docked and cut into two sections, the bow section was moved out by sliding it from the dock onto a pontoon, on the frames laid on the sliding beams and Teflon used for better traction. At that time, the ready-made new insert was already on the pontoon. After the pontoon has been rotated by a 180° the insert was moved on the heavy lift trolleys into the dock, and joined the stern section. Thereafter it was secured against displacement. Again, after the pontoon rotation by a 180° was repeated, the bow section of the vessel was slide back onto the floating dock with the same sliding method used. Finally it was joined to the other end of an insert and secured against displacement. Welding was a completion of the job.

For the conversion, the ships’ steel of A, B and E Class was used, and the works were done under the supervision of Det Norske Veritas (DNV). The documentation of a numerical tracing and a batter chart of conversion were delivered by the Shipowner. Other ship’s documentation such as technical drawings, ship’s stability and ballasting documentation prior to and after her conversion, as well as the operation manuals plus workshop manuals were prepared by SHIPREPAIR YARD “NAUTA” S.A.

A number of conversions

 “NAUTA” S.A., has converted as well two sister ships to “LISBLINK”, namely “LYSVIK” and “LYSBRIS” and another ships belonging to the same shipowner such vessels as: “LYSTIND”, “LYSKOG”, “LYSFOSS”.
