THE TRADER
30,000 DWT international deep sea, 5 holds, wide hatch type multipurpose dry cargo and self trimming type, double skin bulk carrier with provision for grab handling, 14.3 knots, equipped with MAN B&W 6S42MC MK VII Marine Diesel Engine, 4 sets hydraulic level luffing cranes and hydraulically operated end folding hatch covers.
BASIS OF THE TRADER DESIGN
The design features of the TRADER vessels have been developed through research and consultations with our many internationally prominent and successful clients. The latest trends in type, parcel size and trade in international deep sea transportation, the future requirement of ballast handling in restricted waters, the latest trends in shipboard manning practices, latest regulations governing pollution, ballast management safety and communications have been incorporated in the TRADER design. Latest developments in structural analysis, ABS SAFEHULL and finite element analysis have also been incorporated in the design.

CHARACTERISTICS OF "TRADER" SERIES
Developed by the same organization that developed the ‘F’ series such as “FREEDOM”, “FORTUNE”, “FRIENDSHIP”, “FREEDOM MKII”, “FANTASY”, “FESTIVA”, “FORTUNE MKII”, “GALAXY” AND “VALIANT” type vessels. The well proven design philosophy of the ‘F’ series such as cargo flexibility, operational safety and economy and realistic capital cost by series building will be the basis of the “TRADER” series.

The following major characteristics shall be applied:
Worldwide transportation including Panama and Suez Canals Strengthened for heavy cargoes – cargo hold tank top is strengthened for grab handling
Five (5) Cargo holds all double skinned and corrugated bulkhead Tank top strength – 20 t/m2
Wide open hatches ( > 75% of beam) for easy spotting of cargoes Cargo hatch cover uniform load complying with IACS URS 21 (Rev. 3) recommendations
Self trimming grain loading Alternate loading in holds 1, 3 and 5
Ample cargo hold stowage factor of 42 to 55 cub. ft/LT at designed draught condition Provision for radio controlled grab handling
Flexibility of carrying various cargoes such as:   Other characteristics:   
  - Dry bulk and break bulk such as grain, metal concentrates, coal, iron ore, bauxite, salt, sugar, cement in bags and scrap metal Centralized fresh water cooling system in engine room
  - General cargoes such as steel products, forest products, packaged freight and palletized cargo Plate coolers for central cooling system
 
-
