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.

What is a steering system?

A crucial, yet often overlooked, component that ensures the safe navigation of a vessel is the steering system. The steering gear is indispensable, whether it’s for a tug boat, supply vessel, cargo ship, state-of-the-art cruise liner or military vessel. Its primary function is to control the direction of the ship.

Reliability is paramount when it comes to considering a steering gear system. At SIT, we understand the importance of a quality product which can be fully compliant with all applicable customer, military, and industry standards including ABS and USCG requirements.

At SIT, we design and build a complete range of steering gear systems, including hydraulic ram with tiller and low-pressure rotary vane.

A-Frames: Functions & Applications

An A-frame is a distinctive framework that resembles the shape of the letter “A.” You’ll typically find it mounted on the deck of various types of vessels, from research vessels and offshore platforms to fishing boats and even some military ships. The structure is primarily made of robust steel beams, meticulously designed to withstand the harsh conditions of the open sea.

So, what exactly does an A-frame do?

  1. Lifting and Deployment: One of the primary purposes of an A-frame is to facilitate the lifting and deployment of heavy equipment and objects into the water. This could range from submersibles and remotely operated vehicles (ROVs) used in underwater exploration to large fishing nets and scientific instruments. The A-frame’s design provides a sturdy platform for controlled lowering and raising of these items, ensuring a smooth operation even in rough seas.
  2. Research and Exploration: Research vessels often use A-frames to launch and recover equipment for scientific investigations. Whether it’s collecting samples from the ocean floor or deploying sensors to measure environmental parameters, the A-frame’s robust structure ensures that delicate and valuable instruments can be handled with care.
  3. Subsea Construction: In the offshore industry, A-frames are utilized for subsea construction and maintenance. They enable the precise positioning of heavy structures, such as underwater pipelines, installation of oil rigs, and the assembly of various components required for offshore operations.
  4. Rescue and Recovery: A-frames are crucial in search and rescue operations, allowing swift deployment of lifeboats and rescue vessels. Their efficient design enables quick response times during emergencies, potentially saving lives in critical situations.
  5. Diving Operations: When divers are involved in maritime activities, A-frames can provide a secure platform for divers to enter and exit the water. These structures help in managing diving operations, ensuring the safety and comfort of divers during their missions.

Engineering Ingenuity and Design:

The engineering behind A-frames is a blend of strength, stability, and adaptability. These structures can be designed to withstand dynamic loads, intense vibrations, and the corrosive effects of saltwater. Their versatile design allows for customization based on the specific needs of the vessel and the tasks to be undertaken.

The next time you spot an A-frame on a vessel you’ll have a newfound appreciation for its significance. These seemingly simple structures are a testament to human ingenuity, contributing to safer, more productive, and possibly adventurous journeys across the vast oceans. Contact SIT to learn more about our A-frame capabilities.

SITs Defense Capabilities

SIT has a long history working on defense projects to deliver solutions including but not limited to launch and recovery systems, movable doors, hydraulic power units and ballast control systems. But what function do these provide on military vessels?

Launch and recovery systems: Launch and recovery systems on military ships play a crucial role in the operation of various aircraft and watercraft. These systems enable the efficient deployment and retrieval of aircraft, remote operating vehicles (ROVs), and other specialized equipment. Specific launch and recovery systems vary depending on the type and purpose of the military ship.

Movable doors: Movable doors on military ships serve various functional and strategic purposes. These doors are sometimes referred to as “watertight doors” or “bulkhead doors” and are designed to enhance the safety, protection, and operational capabilities of the ship.

Hydraulic power units – Hydraulic power units (HPUs) play a crucial role on military ships. These units provide hydraulic power, which is the use of pressurized fluid to transmit and control energy, for various functions on board. The effected equipment may vary depending on the type of vessel, its intended mission, and the technology available at the time of construction.

Ballast control systems – Ballast control systems on military ships are used for maintaining stability, buoyancy, and maneuverability of the vessel. These systems ensure that the ship’s center of gravity remains within safe limits during various operational conditions, such as loading and unloading cargo, changing sea conditions, and operating various onboard systems. Overall, the ballast control system ensures the vessel can operate effectively and safely in various conditions while performing its mission tasks.

What is an HPU?

A hydraulic power unit (HPU) is a mechanical system that generates power through the use of fluids, typically hydraulic fluid. It is often used to provide the power required to operate hydraulic machinery and equipment, such as hydraulic cylinders, motors, and valves.

An HPU consists of a hydraulic pump, a motor or engine, a reservoir for holding hydraulic fluid, filters to remove contaminants from the fluid, and control valves to regulate the flow of fluid to the hydraulic system. The pump is responsible for creating the pressure required to move the hydraulic fluid through the system and power the hydraulic components.

Hydraulic power units are commonly used in industrial, construction, and manufacturing settings to power equipment such as presses, cranes, lifts, and excavators. They are also used in mobile applications, such as hydraulic systems for trucks and other vehicles.

Overall, hydraulic power units are essential for providing reliable and efficient power to hydraulic systems, allowing them to perform a wide range of tasks with precision and control.

SIT provides the hydraulic calculation package, classification society approvals, operation manuals, integration testing, on-site commissioning and post-delivery service.
