Vessel sensors for shipbuilding

Vessel sensors play a crucial role in shipbuilding, providing essential data for vessel maneuvering and performance monitoring. SenTec offer shipbuilding vessel level and pressure sensor solutions with accuracy and dependability.

Shipbuilding ballast tank

In ships industry, shipbuilding ballast tanks are an integral part of a ship's design and construction. These tanks are used to maintain the ship's stability by adjusting its buoyancy.

Typical application scenarios

Level measurements for the control of draught, trim and list

Among the most important measurements on board ships are those for determining draught, trim and list. In general, one measuring point is placed on the bow and another is used in the aft. On larger ships, two additional measuring points are installed on both the port and on the starboard. Accurate level measurements are required to determine the exact values of ship position and draught.

Level measurement in the forepeak, wing and double bottom tanks with ballast water

The ballast water measurements in the wing and double bottom tanks go directly into the control system for the ship trim, draught and list. Since these measuring points are virtually inaccessible during operation on board, reliability and stability are an absolute must. Pressure shocks, abrasive sand particles and seawater place additional heavy demands on the instrumentation.

Ballast tank liquid level and limit measurement

When the ship encounters wind and waves, asymmetry in cargo loading and unloading, or centrifugal force generated by rapid turns, the anti-heel system can correct the ship’s inclination. It consists of ballast water tanks connected by a piping system, which can resist the heeling of the ship caused by various reasons. Depending on the tilt of the ship, pumps or blowers (compressors) in the ballast tanks fill or empty the tanks with air. In order to achieve control of this anti-rolling system, reliable level measurement is necessary.

Pressure and liquid level measurement of ballast water tank of heavy-duty semi-submersible ship

A semi-submersible ship is characterized by having many ballast water tanks, which allow the ship to sink its deck into the water to carry large floating cargo. By pumping water out or moving air into ballast tanks, ships can lift their cargo and maintain balance. In order to prevent damage to ballast tanks due to overpressure or underpressure, it is necessary to continuously monitor the pressure and liquid level in the tank.

Shipbuilding cargo tanks

Cargo tanks for shipbuilding are specifically designed to store and transport various types of cargo, particularly oil. These tanks are equipped with inert gas systems and crude oil washing systems to ensure the safety and efficiency of oil storage.

Typical application scenarios

Ship cargo tank liquid level, limit and pressure measurement

According to strict safety and environmental regulations, it is imperative to monitor the liquid levels in cargo tanks on board chemical tankers, especially during loading and unloading operations. This is because if a tank full of cargo leaks, the medium may flow onto the deck or into the seawater, causing devastating consequences to the human body and the environment. In addition, in order to prevent damage to the cargo hold due to overpressure or underpressure, the pressure inside the cargo hold also needs to be monitored.

Pressure, level and level measurement for liquefied natural gas (LNG) applications

When LNG ships transport liquefied natural gas, they store it in insulated containers at -162°C. The measuring instruments used must be specially designed for this extremely low temperature environment. When transporting LNG, it is necessary to reliably measure the pressure, liquid level and limit of the cargo tank.

Loading and unloading pipe head pressure measurement

On a tanker, a manifold joint or Manifold is a part used to connect hard pipes or hoses when loading and unloading cargo. Monitoring of pipeline pressure at the Manifold secures installations both ashore and on board and controls the operation of pumps. For safe cargo handling, reliable pressure transmitters are indispensable.

Cargo oil tank liquid level and limit measurement

The extracted crude oil will be pumped directly into the cargo oil tank on the ship, and then the oil, gas and water will be separated by gravity to form layers. In order to maximize the capacity utilization of the oil storage ship and effectively control the operation of the oil pump, it is necessary to continuously measure the liquid level and monitor the limit.
