Builder Samsung Heavy Industries (010140.KS)
Harad is the first in a four-ship double-hulled series of VLCCs constructed for Hellespont of Greece by the South Korean builder Samsung Heavy Industries. During construction, the four vessels were re-sold to NSCSA of Saudi Arabia. The vessel, which incorporates a number of technical features to ensure high levels of environmental protection and high performance, holds a large main engine, improved strength by incr (NCR)
eased plate thickness, improved service lifetime for coatings by increased paint specification and advanced inert gas system.
The hull form of the vessel has been specifically remolded to meet Hellespont's requirements and differs from the conventional VLCCs, featuring a 'blunt' fore part and a breadth of 190 ft. (58 m) to reduce hull deflection. As a result Harad benefits from a reduction in hull deformation by around 10 percent. This has been achieved by strengthening the primary member, double structures and buttress. The hull structure has been designed in accordance with the requirements of ABS Safehull and LR' ShipRight, with a structural quality maintained with the usage of higher tensile steel to 45 percent of the total hull structural steel weight. In addition Z quality steel were used for outermost strake in the inner bottom and 'E' grade steel in the lowest hopper strake.
The number of individual components within the hull structures and the size of the painting area in the water ballast area have been reduced by using a construction method based on one internal bottom plate for each block. According to the shipyard, this reduces the number of maintenance points onboard the vessel. Local strength requirement means that the bottom longitudinal stiffener of the cargo well has to be 18 mm thick compared with conventional VLCCs, which tend to be 12 mm. This approach virtually eliminates the possibility of welding defects and subsequent paint damage since there is no welding seam.
HARAD is powered by an Samsung Wärtsilä NSD 8RTA84T-D engine developing (MCR) 33,300 kW (44,640 bhp) at 76 rpm. The service speed is 16.1 knots at main engine output of 26,780 kW (35,900 bhp) including 15 percent power margin. The main engine operates on heavy fuel oil with a maximum viscosity of 700cSt at 50°C. The large power main engine enables considerably higher speed when utilizing the NCR of the engine.
The ship has a total of 15 cargo oil tanks with a combined capacity of 342,510 cu. m. at 98 percent loading. In addition, there are two slop tanks fully coated in tar epoxy with a capacity of 7,030 cu. m.. The cargo pumping system allows for a maximum discharge rate of 15,000 cu. m./hr. at a head of 160 mlc via three main pumps. The maximum loading rate is 20,000 cu. m./hr. Three grades of oil can be handled simultaneously through a two-valve segregation arrangement.
The ship is outfitted with an inert gas system with
double scrubbers, which reduces the SO2 content to less than 2 ppm.
