Onomichi dockyard Co., Ltd. (ODC) completed construction of two 47,000 DWT type product carriers, Amazon
and San Jacinto, for OMI Corporation
in January and March 2002, respectively. The carriers are the 30th and 31st carriers of the 47,000DWT series built since the first in 1995. The company will build ten more product carriers, which are now one of the best sellers among standardized vessels built by the company.
The 47,000 DWT type series is designed under the policy of building “double hull product carriers at low cost for efficient oil product transport.” The series has a maximum beam of 32.2m, which can pass through the Panama Canal, and a dept of 19.1m, which is the maximum depth to retain the ship stability. The carrier has 53,600m3 cargo space, enabling segregation to load four types of oil products simultaneously. Bulkheads are provided along the centerline except in the Nos. 1 and 2 cargo tanks, two slop tanks, and one residue tank. Four cargo pumps with a capacity of 1,000m3/hr x120t/h are installed for efficient cargo handling. Other safety measures include a vapor emission control system, an inert gas system for the ballast tanks, safety accesses to the bow section, environmental safety (ES) routine, etc.
To cope with recent requirements, a service speed of 15.3 knots is guaranteed, faster than 14.5 knots of the previous 39,000 DWT carriers. Use of the Mitsui-MAN B&W 6S50MC type diesel engine and improved hull form enable high-speed navigation. The product carriers for OMI Corp. can load low corrosion chemicals and protective wear and eye washing equipment are provided for transport of sodium hydroxide in compliance with the IBC Code. To cope with low corrosion chemicals, cargo pumps are made of SUS and upgraded packings are used. Expansion loops are also used for the cargo pipes. The level gauges are the radar type and an inboard LAN system is installed to upgrade the carriers. A helicopter landing space is also provided.
