What is valve actuation?

In marine applications, valve actuation refers to the process of opening and closing various types of valves on ships and other marine vessels to control the flow of fluids (such as water, oil, fuel, or gases) within the vessel’s systems. These valves play a crucial role in ensuring the safe and efficient operation of different systems on a ship, including those related to propulsion, ballast control, cooling, heating, and various other functions.

Valve actuation in marine applications typically involves the use of mechanical, hydraulic, pneumatic, or electrical systems to operate the valves. Here are some common types of valve actuation mechanisms used in the maritime industry:

  1. Manual Valve Actuation: This involves manual operation by a person turning a valve handle, wheel, or lever. Manual valve actuation is often used for smaller and less critical systems on board ships.
  2. Hydraulic Valve Actuation: Hydraulic systems use pressurized fluid to control the movement of valves. Hydraulic valve actuators are suitable for larger and high-pressure applications, such as those found in the ship’s propulsion system or steering system.
  3. Pneumatic Valve Actuation: Pneumatic actuators use compressed air to operate valves. They are commonly employed in less critical marine systems, such as those for cargo handling.
  4. Electric Valve Actuation: Electric actuators use electrical power to control the valve’s position. They are used in a wide range of marine systems, including ventilation, water treatment, and other automated processes.

Valves can serve various purposes on a ship, including regulating the flow of fluids, isolating different sections of the ship’s systems, and providing emergency shut-off in case of a system failure or emergency. Proper valve actuation is critical to maintaining the safety, performance, and efficiency of a vessel’s operations. Valves need to be regularly inspected, maintained, and operated to ensure they function as intended.

SIT partners with Emerson to provide valve actuation for customers in various marine applications. As the exclusive partner for Emerson offshore applications in North America, SIT has the local presence to provide excellent customer support as well as the backing of a globally recognized manufacturer.

Myth vs. Reality – Use of ROVs in Subsea Drilling Operations

Myth vs. Reality – Use of ROVs in Subsea Drilling Operations

Supreme Integrated Technology, Inc. is proud to partner with many clients to deliver equipment necessary for subsea drilling operations. One of the interesting technologies we are able to assist with is underwater remotely operated vehicles (ROVs) which have replaced the need for human divers in many operations.

Myth: ROVs are not reliable for subsea drilling operations.

Reality: ROVs have proven to be extremely reliable for subsea drilling operations. They are equipped with advanced capabilities such as high-definition cameras and sophisticated manipulator arms, which allow them to carry out a wide range of tasks with precision and accuracy. In addition, ROVs can be remotely operated from the surface, which eliminates the risk of human divers needing to work in dangerous and harsh underwater environments.

Myth: ROVs are too expensive.

Reality: ROVs offer a number of benefits that can offset the cost. For example, they allow companies to drill in deeper waters, where traditional drilling methods are not possible. Additionally, the use of ROVs can improve the efficiency of drilling operations, as they can be operated around the clock and are not subject to the limitations and risks associated with using human divers.

Myth: ROVs are not as effective as human divers.

Reality: In many cases, ROVs are more effective than human divers for subsea drilling operations. ROVs are equipped with the following technologies:

High-Definition Cameras: show live video feeds to the operator on the surface. This allows the operator to see what the ROV is seeing in real-time and to make decisions based on that information.

Manipulator Arms: allow them to manipulate objects and carry out a wide range of tasks, such as retrieving samples, cutting cables, and installing subsea equipment.

Thrusters: deliver precise and efficient propulsion and maneuverability. The thrusters are designed to allow the ROV to move quickly and smoothly in any direction, which is essential for many subsea tasks.

Navigation Systems: provide precise position and orientation information. This is critical for tasks such as subsea survey and inspection, where accuracy is essential.

Communication Systems: allow the operator to control the ROV and receive real-time data and video feeds from the subsea environment.

Power Systems: power ROV’s various systems and components. This allows the ROV to operate for extended periods of time without needing to be recharged.

ROVs are critical for avoiding the limitations and risks associated with human divers, such as decompression sickness and other health risks associated with working in harsh underwater environments.

SIT has worked on various systems for ROVs including valve controls, deck controls and hydraulic power units. We specialize in tough applications and have the ability to design lightweight systems that can withstand harsh environments of saltwater and deepwater operations.

Specification of Hydraulic Power Units

Step #1 Start with the carefully understanding the application. A hydraulic power unit (HPU) supplies fluid power to various hydraulic actuators including cylinders and motors. The requirements of the items that the HPU looks to power will dictate the max working flows and pressures.

  • Defining max working flow: calculated by the number and types of cylinders and motors that are operating at the same time, at the required speed.
  • Defining pressure: calculated by determining the necessary force needed to perform the duties of each actuator.
  • Calculations: pressure & flow can be determined through straightforward formulas, see our reference sheet.
  • Size constraints: HPU location may factor into the size of components, reservoir, and other design decisions.

Step #2 – Selecting a pump. Many options for pumps exist – simple gear pumps, piston pumps, bent axis pumps and other options. Rotary gear pumps are generally the most cost-effective solution, and require less maintenance, but may not meet the criteria to achieve higher pressures and speeds. The style of pump may also be dictated by required flow & pressure as well as size constraints for the application.


Step #3 – Determine configuration. Pumps are usually mounted near the reservoir which allows for easier maintenance access. However this requires the pump to lift the fluid with suction before pressurizing the systems which may make the tank harder to clean. Pumps can also be mounted alongside the tank or below the tank.


Step #4 – Designing reservoir. ISO 4413 is commonly followed as the industry standard for design of HPUs, and it dictates the roles for the reservoir. The tank must dissipate heat generated during normal operations, must hold all fluid under normal system operation, and must allow for adequate room for thermal expansion. It also defines separation between incoming fluid and pump intake, allowing returning fluid to be able to release trapped air and permit contaminates to settle. Usually, a hydraulic reservoir is 3-5x the per-minute flow rate.


Step #5 – Pressure relief. A pressure relief valve is essential to limit max system pressure by allowing fluid to return to tank when the system is not using the full volume of flow from the pump. Determining the right size for a pump is critical because if the pump is too large for the system, the pressure relief valve will be constantly working, wasting energy and creating heat.


Step #6 – Filtration. Maintaining clean fluid is essential to any hydraulic system, and all HPUs must include a filtration system. Options include using filtration on the pressure side of the pump to protect for contamination in the rest of the system. Pressure side filtration can be cumbersome because of contamination build up across the pressure drop and the filter housings must withstand the pressures produced by pump. Return-line filtration is an option which helps keep contaminates out of the tank with lower pressure requirements.


These are just the initial steps to consider when sizing an HPU. HPUs often have sophisticated controls, valves, gauges and sensors. Supreme Integrated Technology designs and builds HPUs for a wide variety of applications including for the military, industrial, oil & gas, marine and civil industries.

What is included in a ballast control system?

Ballast control systems are an integral part of many types of vessels, including deepwater oil & gas drilling rigs, container vessels, autonomous spaceport drone ships, military aircraft carriers, landing support vessels, combat ships and much more. Depending on the vessel, the ballast control system has a variety of functions, but all have the same basic components. This article will review the basic components of a ballast control system and consider some of its functions.

Ballast Control System Components

Ballast tanks – these tanks hold the water that ballast the ship. They are located in strategic locations on the vessel to help balance the load of ballast and allow controllability of the ballast weight, depending on its function. Depending on its size, a vessel may use just one ballast tank to as many as over 16 strategically located throughout the vessel.

Valve/Actuator Assemblies – valves control the flow of water based on commands from the central control system. Actuators control the valve opening/closing and can be hydraulic, powered by a network of hydraulic lines running throughout the ship. In newer versions of ballast control systems, the valves are often electrohydraulic and only require an electric signal to change position, thus eliminating the need for hydraulic piping.

Flow Meters & Transmitters – sensors located inside the ballast tanks. These sensors detect levels of water and communicate messages back to the control center. These messages allow an operator to accurately operate the ballast system.

Control Stations – for the sake of redundancy, topside controls stations are usually located on the deck of the vessel, in close proximity to each ballast tank (I/O control cabinets). All control signals would also run to central control system, which is the primary used system and is usually located in the ship’s bridge or main control room.

Ballast Pump Skid Control – this is the main power unit with the suction pump to remove water from ballast tanks and control main power for valve actuators on each ballast tank.

Examples of Ballast Control System Functions

Deepwater platforms (7,000-20,0000 ft. drilling) may use ballast control systems for a couple different purposes. First, when the platform is static, it will be anchored to the ocean floor with a large cable system. The ballast system is used at the initial anchoring to ballast up to the cable system and provide small changes during the duration of the vessel anchoring to adjust for storms or other extreme weather conditions. Dynamic ocean platforms (not anchored, free-floating), which are typically used for the deeper oil & gas drilling, as well as autonomous spaceport drone ships to catch rockets, constantly use ballast control systems to balance deck loads despite changing sea conditions and keep the floating vessel in a secure location.

A second example of ballast control systems occurs with military vessels. For vessels transporting equipment from the water to the shore, the ballast control system is used to sink the front of the vessel and allow the equipment to easily offload into shallow water. In larger combat vessels, ballast systems are built to provide extra security in case the vessel encounters a strike during battle. The vessel can take on ballast in one area to counteract the damage in another area of the vessel.

Ballast systems are often complex and custom designed for each vessel. Supreme Integrated Technology, Inc. partners with customers in marine, aerospace and military industries to help design, build and test systems used in the most difficult operating conditions.
