LPG Tanker Repaired, Modernized and Converted

September 16, 2003

The 977-ft. LPG tanker Matthew was docked on August 17 into dry dock Elbe 17 of Blohm + Voss Repair GmbH to be repaired, modernized and converted in 33 days. The ship will be berthed at the quay for another 12 days so that tests can be carried out and the equipment set to work in cooperation with the crew, which stayed on board during the docking period. The Matthew, a large order for the traditional Hamburg shipyard, has hundreds of people working around the clock, seven days a week so as to hand over the ship to Cabot LNG Corp as scheduled. The tanker is in service on the route from Trinidad to Boston transporting natural gas, which is taken on board in liquefied form at a temperature of -162°C. The special feature is that this temperature is maintained during transport just by the excellent insulation of the tanker. The MATTHEW was the first tanker allowed to sail into the port of Boston after September 11.

Blohm + Voss Repair installed a new 2,100 kW auxiliary engine with a weight of 52,000 kg to ensure a safer future power supply. For this, a new engine room was required, which was completely fitted out with all auxiliary equipment by the yard. Adjacent to the engine room a workshop was arranged and several modernizations were carried out to make the tanker commissioned in 1979 and laid out for a life of approx. 40 - 50 years fit for the coming years. Blohm + Voss removed an anchor winch with a capacity of 55,000 kg and four mooring winches and installed five new mooring winches each with a pulling power of 75 t. Two old life rafts were replaced by a free-falling rescue boat arranged at the stern. Extensive repair work was completed by Blohm + Voss specialists in all 26 ballast water tanks to meet the classification regulations. Gas loading systems and cargo pumps were overhauled. In addition, the propeller shaft was removed and the sealing system renewed using new Simplex seals produced by B+V Industrietechnik, a company located next to the yard. Furthermore, 34,000 m² of the outer skin were preserved and various pipes and valves of various systems such as the steam, ballast water and sounding system were renewed.
