SHIPBUILDING SHOP
“One of the important shops in the Production Department is the Shipbuilding Shop. Nearly 10,000 square meters are devoted to this shipbuilding facility, which includes two sizable work sheds where the ship's main hull is constructed. To carry out the fabrication operation efficiently, a variety of tools and machinery are available, including three CNC machines, bending machines, shearing machines, hydraulic press machines, welding machines, and plasma cutting machines. Additionally, the shipbuilding shop employs nearly 100 qualified welders and 200 highly skilled fitters. The ship building shop excels in working with steel and aluminum. According to the needs of the customer, the shipbuilding shop can manufacture a wide range of high-quality products (including IPV, FPB, high-speed sailboats, pontons, buoys, LCU, etc.). The shipbuilding workshop transforms the virtual hull model into a physical one.” Activities of the shipbuilding shop: The shop carries out numerous types of work, including the following tasks: 1. Prepare structure of hull and superstructure of different types of boat. 2. Repair works of hull and superstructure of vessels. 3. Prepare the nesting and programming drawings for CNC cutting. 4. Prepare different engineering structure (Buoy, steel foot over bridge, ramp etc.) 5. Prepare various outfitting items (Such as: Manhole, hatch, railing, mast, ladder, stair etc.)
DOCKING SECTION
The process of docking and undocking a new or repaired ship is carried out by the Docking Section. Docking is done with the aid of a series of drawings and plans, which designers prepare based on specific calculations. Hence, knowing docking processes, docking calculations, etc. DEW’s docking section plays a vital role by handling heavy machines (cranes, forklifts, etc.), which keeps the yard dynamic and alive. There are two main docking yards at DEW. One is situated on the Northside and the other one is on the Southside. The team of this section is formed by skilled Engineers, Divers, Dockers, Crane & Forklift Operators, Riggers, Heavy Machinery Operators and Helpers etc. Docking Section Features and Specifications: The capacity of Docking :1500 ton No. of slipway:13 nos. Length of slipway towards river:270 feet Main Machineries of Docking Section: 1 X 20 ton portal Crane 1 X 30 ton mobile Crane 1 X 25 ton mobile Crane 1 X 40 ton Floating Crane 1 X 100 ton mobile Crane 2 X 5 ton Forklift
PAINT SHOP
The painting plays a big role not only in improving the appearance of the ship but also in its safety by preventing corrosion and fouling on the bottom of the ship. Furthermore, painting standards are strengthened to comply with environmental problems, so painting is a very important process in shipbuilding. Our paint shop is capable of meeting the above-mentioned requirements with international standard. The paint shop has 32 skilled workers and all the tools and machines they need, like three air compressors with a capacity of 7–10 bars, three spray painting machines, and two sand blasting machines with a 6 mm nozzle with necessary tanks. Activities of paint shop: • Surface preparation of various types of hull (steel, aluminum) • paint the hull using spray painting or roller painting applications. • Mechanical disking, hand scraping, and degreasing • Surface cleaning by sandblasting or sweep blasting • adheres to proper air temperature and relative humidity • Apply cement or food-grade paint to a fresh water tank.
