Marine and offshore equipment operates in some of the harshest environments on earth, where components are exposed to heavy mechanical loads, continuous vibration, seawater corrosion, and demanding operating conditions. Reliable forged components are essential for ensuring the safety, durability, and long-term performance of ships, offshore platforms, and marine equipment.
Eternal (Wanheng) specializes in manufacturing custom open-die forgings for marine and offshore engineering applications. With more than 20 years of forging experience, we supply high-quality forged components designed to meet the demanding requirements of commercial shipbuilding, offshore oil & gas platforms, marine propulsion systems, and other heavy-duty marine equipment.
Our custom forgings are widely used in a variety of marine and offshore equipment, including:
• Marine Propulsion Systems – Propeller shafts, intermediate shafts, rudder stocks, hubs, couplings, and other critical drivetrain components.
• Offshore Platforms – Forged flanges, rings, structural connectors, support components, and customized forgings for offshore drilling and production facilities.
• Deck Machinery – Forged shafts, pins, rollers, gears, and structural parts for winches, cranes, anchor handling systems, and mooring equipment.
• Steering Systems – Forged rudder components, steering shafts, bearing housings, and heavy-duty mechanical parts.
• Marine Equipment – Custom forged rings, sleeves, cylinders, blocks, gear blanks, and other components manufactured according to customer drawings and technical specifications.
• Superior Structural Integrity – The forging process refines the internal structure, minimizes porosity and segregation, and produces dense, high-strength components for demanding marine environments.
• Enhanced Mechanical Performance – Optimized grain flow improves fatigue strength, impact toughness, and resistance to cyclic loading during continuous operation.
• Near-Net Shape Manufacturing – Forgings are produced close to final dimensions, reducing machining allowance, minimizing material waste, and improving manufacturing efficiency.
• Excellent Reliability in Harsh Environments – Forged components deliver long service life and dependable performance under heavy loads, continuous vibration, and corrosive marine conditions.
We manufacture custom forgings in carbon steel, alloy steel, stainless steel, duplex stainless steel, and other engineering materials according to customer drawings and technical specifications.
Our integrated production capabilities include open-die forging, heat treatment, rough machining, finish machining, ultrasonic testing, mechanical property testing, and comprehensive dimensional inspection to ensure consistent product quality.
All forged components are manufactured in accordance with international standards including ASTM, DIN, ISO, and customer-specific requirements to meet the demanding quality expectations of the global marine and offshore industry.
Whether you require forged components for new vessel construction, offshore platform fabrication, marine equipment manufacturing, scheduled maintenance, or emergency replacement parts, Eternal (Wanheng) provides customized forging solutions with consistent quality and dependable delivery.
Our engineering team works closely with customers to optimize material selection, forging processes, and machining allowances, helping improve equipment reliability while reducing total manufacturing costs.
