The hydraulic technology also gets used in many other ways. You will find it used in the platforms and passerelles, adjustable pitch propellers’ rotary operation, and the remotely operated doors, valves, ventilation flaps, etc. in both their linear and rotary operation. On certain large vessels, you may find the technology used in other ways. Of course, its application grows each day, so next year, you may find hydraulics applied to the marine industry in other ways.
While the equipment and machinery depend on the type of ship, hydraulics often run the cargo pumps and lines which includes many line valves. Manual operation of these would make for a time-consuming operation so ships automate using hydraulics so they can control all cargo, bunkering and ballast operations from a control room mimic diagram.
A variety of machines on the deck use hydraulic including the cranes, winches, and mooring drums. You will also find that hydraulics used in the operation of the capstans, emergency towing arrangements, windlass, hatch covers, and other equipment covers. The function of the hydraulic systems within these are to make the operation smoother. These typically heavy latches and covers benefit from a hydraulic hinge that makes it seem lighter. On bulk carriers, the derrick or deck crane uses hydraulics in the loading and unloading of cargo. You will also find the technology used in mooring winches and the anchor. These systems run on hydraulic oil transported under high pressure through hydraulic motors.
As ships increased in size, they increased in weight which increased the needs for propulsion. The use of hydraulic tightening enabled the use of large reciprocating pistons. The technology holds together the bed plate, cylinder heads, and entablature. It powers the stabilizers that keep the ship from rolling. This adds to the comfort of those on board. In smaller boats, the hydraulic system attached the rudder and steering wheel to make steering easier.
There are many different marine hydraulic applications, including automation and control systems, deck equipment, and critical valve systems. If these systems, and the various components that comprise them, are not maintained properly, the results can be both costly and unsafe — a bad combination for any business. However, regular maintenance, such as filter changes, hose replacement, lubrication, cylinder resealing, and more, can keep marine hydraulic equipment performing reliably.
Valves are extremely important to any hydraulic system, whether it is the simplest hydraulic cylinder or the most complex of rudder systems. Valves control the flow of hydraulic fluid, adjust pressures within different parts of the system, and keep pressures stabilized at safe levels. Some of these valves may be so small as to seem insignificant (they are not, though) while others may be extremely large. Valves are used to direct the operation of many different systems onboard ships, including engine systems, automation, control systems, cargo and passenger loading, and power. However, valves are also used for functions specific to different types of ships (e.g., oil tankers, cargo ships, yachts).
Depending on what the valve system is part of, a failure here ranges from a slight reduction in performance to life-threatening issues or environmental disasters (i.e., petroleum and chemical transport). If filters are not changed when needed or there is hydraulic contamination in the system, critical valves can become clogged and unresponsive. This could allow a dangerous buildup in pressure or cause other parts of the system to malfunction.
The use of hydraulics in the automation of the engine room, specifically in hydraulic automated control systems, reduced the need for large crews. A small crew of 13 to 15 individuals can now power the entire ship. Hydraulic automation opens and closes valves, maintains pneumatic air pressure, and, as a result, controls hydraulic oil flow. For many companies, this makes it more feasible to put more ships in the water which allows them to do more business whether that refers to oil rigging or oversea transports.
Today’s naval and commercial ships require immense power. Moving their cargo loads and controlling complex interior mechanisms requires heavy lifting. What once required massive crews now requires 15 or less individuals because of the use of hydraulic technology. Their high-power density coupled with their simple control systems make them a sensible choice for ships, regardless of their size.
They can easily interface with other systems such as Global Positioning System (GPS), radar systems, and the programmable logic controller (PLC) used to streamline control of most of the ships. The ease of integrating hydraulics into the shipboard computer makes the entire vessel easier to control and increase run efficiency.
Use of these systems also makes system redundancy simpler. The efficiency of design and implementation makes installation of a hydraulic pump and a standby pump reasonable. Similarly, control valves enable the installation of backups without taking up too much space or inhibiting motor function or slowing propulsion.
As hardy as hydraulics function, you cannot expect them to always run perfectly. You will have breakdowns on any ship. Rather than replace the entire system, let PEHEL Hydraulics repair it. Our company repairs hydraulic cylinders
, hydraulic hose repair
, and hydraulic hose guards
We go beyond repairs to providing education in our blog. This helps you learn how to prevent problems by knowing how to conduct simple maintenance checks yourself and how to recognize common problems that might cause a hydraulic breakdown. In these readable, simple to follow blogs, we make it easy to understand the inner workings of your hydraulic systems. This helps you discover developing problems before they cause a breakdown in ship operations. When you see something becoming an issue, you can call us. This lets the PEHEL Hydraulics team conduct preventive repairs and helps you maintain business continuity.
We service all sizes of ships and small watercraft. Whether you need repairs to your sailboat, yacht, or your company’s shipping vessels, we can repair it.
