Shipbuilding

Modern and efficient ships are the backbone of global economic development. 80% of all goods come to us via the seven seas.
The series construction of standard ships has shifted to the Far East for cost reasons. European shipyards are focusing on special shipbuilding in the high-tech sector. This includes ro/pax and ro/ro ships as well as mega yachts, cruise ships, work and research vessels.

A new ship combines a large number of materials and components: shipbuilding steel, mechanical engineering parts such as propulsion systems, pumps, valves, as well as electronics in the navigation systems etc. Modern shipyards create something unique: the individual components (around 300,000 for a passenger ship) are assembled into a floating city in less than twelve months.

Ships must comply with the strict regulations on maritime environmental protection and ship safety, SOLAS and MARPOL. In addition, all design and building phases are monitored and inspected by classification societies such as ABS, BV or RINA.

 

Ship classification societies

  • German Technical Monitoring Association (TÜV)
  • Lloyd‘s Register of Shipping (LR)
  • Bureau Veritas (BV)
  • DNV
  • Registro Italiano Navale (RINa)
  • American Bureau of Shipping (ABS)

Efficiency and emissions

Ships still mainly sail on fossil fuels: heavy fuel oil, marine diesel or LNG. There are various approaches to making propulsion systems more efficient. Diesel engines can be combined with wind energy propulsion, e.g. towing kite drives or Flettner rotors. In order to meet emission requirements without purchasing low-sulphur fuel, some diesel propulsions are retrofitted with exhaust gas purification systems ("scrubbers").

Hybrid propulsion systems with batteries are also being planned as a climate-friendly solution, which will allow the route or berthing time to be partly emission-free. Existing engines can also be converted to climate-neutral methanol, but this requires significantly larger fuel tanks. The first hydrogen tankers are also being developed, and fuel cells for maritime use are being researched (e4ships) and tested in practice.

 

Industrial valves for shipboard systems

Self-acting industrial valves from Mankenberg can be found in fuel or lub oil circuits and in water and waste water systems. Careful material selection is essential for use in the highly corrosive maritime atmosphere. Thanks to the deep-drawing process, the valves have a compact design and low weight for installation in hard-to-reach working areas.

Approvals from common classification societies such as DNV, LR, RINA or BV are possible.
