Shipbuilding industryEvery ship and every day bring new challenges

Shipbuilding: This includes passenger, container and freight vessels, tankers, floating oil rigs as well as naval ships. Operating conditions and thus the requirements of automation technology, particularly sensor technology/measurement technology, are similar whether at sea or on inland waterways. This also means an equally broad spectrum of measuring tasks to be solved in port terminals.

What is required:• Resistance to aggressive sea water• Reliable measurement even when there are vibrations• Constant and reliable operation also under high

temperature fluctuations from dry cold (in the polar zones) to the moist heat(in the tropics).

• Highest degree of safety in Ex-zones, e.g. on chemicals/liquefied

• natural gas tankers, in offshore areas (oil rigs, FPSOs etc.)

• Mechanical robustness and resistance to flooding• Reliability through electronic long-term stability• Highest degree of accuracy in stability-relevant

measurements, e.g. in ballast tanks

There is hardly any other means of transport where the standards of cost-effectiveness, functionality and reliability are as high as in ship-operating facilities.

To meet these standards, the measurement technology and control must be absolutely reliable.

This requires a reliable, experienced and competent partner who is aware of the demands and tasks posed in shipbuilding day by day. Endress+Hauser represents know-how in measurement technology, customer-oriented solutions and professional project planning and engineering.

Applications on boardReliable operation of a ship’s engine

Maritime and inland navigation vessels make high demands on the measurement technology Quality measurement on-board. The instrumentation on deck, in particular, is subjected to extreme mechanical and climatic demands. The pounding of the waves (flooding), salt water and vibrations test the sensors, as well as the tropical climate and ice formation in the polar circle.

The tanks on board a ship are often filled with products displaying the most diverse of characteristics. The products transported in the cargo and service tanks display varying characteristics in relation to density, consistency, reflective properties and conductivity. In addition to level and pressure measuring tasks, it is becoming increasingly important to determine flow, temperature and analysis measured values on ships to ensure efficient use of the facilities.

A complete solution from one supplier - Endress+Hauser develops and produces the sensor technology for all of these parameters themselves and thus offer all shipbuilding customers the maximum benefit of a full-range supplier.

Bilge/fuel system in the engine room

Bilge water (sea water, condensation) collects in the bilge, and is mostly mixed in with oil and fuel residue. The water is separated from the waste oil in an oil separation system. The medium independent Liquiphant T/M vibration limit switch controls the system and monitors the level limits in the bilge or waste oiltanks.

To ensure that the fuel cycle functions perfectly, sufficient fuel must always be available in the relevant tank. Levelflex M guided radar instruments are used in the day fuel tanks to provide information on the level during filling and operation. Liquiphant T/M vibration limit switches have proven effective in protecting from overfill and detecting minimum level in the daily service tanks, and in monitoring leakage of the pipes for fuel to the main and secondary units.

Promass E• Easy installation• No moving parts• Measurement without bypasspipe• Direct mass measurement

It is necessary to determine the current fuel consumption to ensure optimal operation of the engine at all times. The new Promass E mass flowmeters are used for this purpose. They deliver a direct signal on the consumption in tons per hour. The mass flowmeters operate independently of pressure and temperature and determine the current consumption with a precision that has never been achieved prior to this.

The position of the ship is always secureEfficient use of the space in the interior of a ship is essential as ships are at sea for several months as a general rule. Clever distribution of the fuel and ballast tanks will ensure that the ship will travel safely at sea even in adverse conditions.

Ballast/ servicetanks

Ships have to be balanced depending on the distribution and weight of the loaded freight. Ballast water is pumped into provided tanks on the ship. This water must be exchanged on high seas to avoid the pollution of flora and fauna at the port of destination. Therefore, it must be possible to monitor and control the complicated distribution of ballast water within the vessel.

Draft, trim, listThe position and draft of a ship changes when it is loaded and unloaded. It is therefore imperative that the draft, trim and list be measured reliably for there sulting ballasting.

Heel/listIf a ship heels, the occupants, cargo and environment are at risk. The reasons are manifold.Unstable conditions, brought about by wind pressure, load and swell for example, can be identified quickly and

safely using modern measurement technology and countermeasures can be implemented. The level and draft are recorded for this purpose and passed to the ship’s monitoring system.

Service tanksAn adequate supply of fresh water, stored in the relevant type of tanks, must be available for the crew and passengers. Wastewater (gray water/black water) that accumulates during a ship’s journey is partly treated directly on the ship or is collected in tanks and supplied to a wastewater treatment system in the port. Endress+Hauser provides measuring devices specifically developed for all of these tasks.

Level measurement in sounding pipesMost ship tanks have sounding pipes to check liquid levels by manual sounding. Additional electronic measurement is possible through these sounding pipes. This type of instrumentation avoids the need for expensive installation and can also be installed retrospectively.

Using instrumentation in the area of freight/cargoDifferent types of freight are transport in different types of ship. Typically, a distinction is quality measurement made between liquid maritime freight - e.g. oil, chemicals or liquefied gas - and solid freight -e.g. gravel, grain or coal. In addition to these traditional types of freight, containers have also become increasingly important.

Freight/ cargo

Water inleakage detectionThe cargo hold of bulk carriers must be continuously checked for leakage to protect the crew, the ship and the environment. Since excessive water in leakage may sink the vessel, the reliability of this measurement and timely alarms are of paramount importance.

The BULKGUARD water inleakage detection system offers three different measurement methods:• The hydrostatic measurement method with Waterpilot• the non-invasive radar measurement method with

Waterpilot FMX21• detection of limits using the vibration principle with

Liquiphant.

The measurement specified by the IMO is neither endangered nor distorted if cargo holds arefilled with fine or coarse material.* IMO = International Maritime Organisation

Cargo tanksThe levels of cargo tanks on board chemicals tankers must be monitored at all times due to the strict safety and environmental requirements. The consequences for the crew and environment could be devastating if the tanks were overfilled and the contents leaked on deck or into the sea.Micropilot M radar devices – used to monitor the level - and Liquiphant M vibration limit switches - used to detect high and high/high alarms, have proven extremely robust and low-maintenance for this purpose.

Exhaust Gas Cleaning and Ballast Water Treatment on ships: analytical measurements

Water treatment

Exhaust Gas CleaningThe IMO has implemented very strict regulations for sulphur dioxide emissions. With the use of an exhaust gas cleaning systems, shipowners can continue using heavy fuel oil instead of the more expensive marine gas oil. But due to these same regulations, the quality of the produced waste water has to be monitored closely. Some of the main analytical parameters are pH, conductivity and turbidity.

Ballast Water TreatmentThe loading of ballast water takes place in another port and sea then the discharge. Therefore, there is a risk of invasive aquatic species. Because of this risk, the IMO has implemented the Ballast Water Management Convention according to which the ballast water has to be disinfected. Main analytical parameter here are Free Chlorine, PSU measurement (conductivity) and UV extinction.

All Memosens sensors can be connected to a single Liquiline CM444 transmitter, providing the user accurate measurements with a minimum of maintenance.

Fresh waterThe quantity of fresh water required for daily hygiene purposes and cleaning varies depending on the type and size of ship. The fresh water quantity stored is generally insufficient and must be continuously supplemented with water from an on-board desalinization plant.

The water quality is monitored using Liquisys conductivity measurement. The fresh water quantity is recorded with FMX 21 Waterpilot probes especially approved for the area of drinking water.
