Industry expert analysis, this year in the global economic recovery driven, future most ship shipbuilding market demand will be restored, but in view of the current shipbuilding market more serious overcapacity problem as well as most ship large orders in hand pressure, shipbuilding market the sustainability of the recovery remains to be further observation. Among them, product oil tanker is expected to take the lead in the recovery; container ship owners recently to profitability, drive the container ship market will restore to good: bulk carrier market oversupply situation, market prospect is not optimistic; motor boat ( PCC ), liquefied natural gas ( LNG ) and liquefied petroleum gas ( LPG ) demand will also slow recovery; cruise, ferry and other relatively stable demand, market supply and demand to maintain a relative balance.
This ship steel industry with new features, needs to be able to satisfy the requirement of new standard for shipbuilding industry high performance green plate. In large bulk carriers, container ships, oil tankers and marine engineering ship for use on high strength steel as an example, the bulk carrier, container ship steel plate ( A32-A36) using the ratio of more than 60%, tanker high-strength plate using the ratio is about30%. According to the end of 2009handheld shipbuilding order statistics, bulk carriers, container ships in China accounted for more than70%, the demand for high strength plate. Especially company of our country shipping orders are mostly large and high value-added ships, high strength plate using proportional in general about 50%.
Insiders said, steel enterprises to strengthen communication and manufacturing enterprises, production adapt to the real ship enterprises demand products. If the market once thought, more than 3.5 meters wide ship for help to reduce the weld and has obvious competitive advantages and great market potential, in fact this awareness has limitation, shipyard technical staff, to ensure the hull structure stress distribution and easy machining of curved surface, even in300000tons super large the ship,3.5 meters wide board using the ratio of no more than 40%,4meters above the deck is used sparingly. Recommendations for iron and steel enterprises rational treatment of high strength ship needs, to avoid the formation of a new overcapacity.
In addition, with the marine equipment were included in the strategic emerging industry, the shipbuilding industry of ship upgrades urgently. Offshore platform service ship class of high50%, the leaf must have high strength, high toughness, fatigue, lamellar tearing resistance, good weldability and corrosion resistance to sea water. From build at present a few platform, an offshore platform steel consumption of about 20000 tons, of which around 90% using the domestic steel, imported about 10% percentage; the varieties of steel is AH-EH grade ship plate, wherein the 6mm,8 mm,10 mm to several thickness specifications of high-strength plate accounted for more than 80%, according to rank, E board to total steel quantity is 70% ～80%; width 2.4meters specifications of steel amount is more, width 3meters above the specifications of steel consumption is less.
