Military, State Orders Buoy Patrol Boat Market
Even before the events of 9/11, the patrol boat market for the Navy, Coast Guard and individual state law enforcement departments was very active. For example, in the 1980's Bollinger built 49 Island Class Patrol boats and 10 years later built 50 smaller patrol vessels also for the Coast Guard. These assets were immediately deployable to counter terrorism threats after 9/11. But with the entire nation on alert, it was obvious that the more sets of eyes and ears we could put on our 95,000 mile coast line the more secure we would be. In the last two years, hundreds of smaller patrol boats have been built specifically to increase security around ports and other facilities across the nation. The Navy has been very active ordering vessels to patrol Navy bases and other military installations.
POSCO to Reset Steel Prices
POSCO is rearranging its steel prices in response to fluctuating international prices and domestic demand. On May 1, the steel producer will lift prices of mini-mill products, stainless steel and cut steel plate prices. In a statement, the company said prices for mini-mill hot-rolled coil will rise by $21 per ton to $501 in the domestic market due to falling inventory levels but prices for steel plate and steel plates for shipbuilding will fall by $31 per ton to $661 and $623, respectively. Its move is affected by recent price cuts by Japanese steel makers. For orders made from May 3, the prices of 300 series hot-rolled and cold-rolled products will each rise by $213 to $2,581 and $2,869 per ton, it said.
