Maintenance winchpontoon

Muns Techniek is a system integrator for Hydraulic systems and Electrical controls. With more than 25 years of experience we offer Hydraulic and Electric Solutions for projects in the Maritime, Offshore and Industry.

Customer

Our client’s winch pontoon was due for major maintenance. Because the pontoon has been in use for several decades, the owner wanted to have the winches inspected, cleaned, and maintained.

In addition, the HPU that controls the winches was experiencing start-up problems, and this installation was also due for major maintenance.

Muns Techniek solution

The winches were removed from the pontoon and transported to our workshop, where they were disassembled, inspected, cleaned, reassembled, and tested.

The HPU was also removed and inspected. Both the housing and the diesel engine were cleaned and repaired, and the control system was overhauled and upgraded.

The main control panel for the winches and the HPU was also upgraded and replaced.

Result

The pontoon’s winches, HPU, and control system have been thoroughly inspected and, where necessary, repaired or overhauled. Subsequently, all components were reassembled and a new control system was installed.

After extensive testing, the entire system is operational again. This ensures the pontoon can be reliably deployed for many years to come.

Hydraulic piping

Hydraulic piping

Muns Techniek is a system integrator for Hydraulic systems and Electrical controls. With more than 25 years of experience we offer Hydraulic and Electric Solutions for projects in the Maritime, Offshore and Industry.

Customer

Hydraulic piping is an essential part of hydraulic systems. These pipes must be custom-made and fitted to the rooms they will be placed in.

The piping must cross spaces as efficiently as possible, must be easily accessible and must be installed properly.

Muns Techniek solution

Muns Techniek has a lot of experience in making hydraulic piping.

Our employees can accurately design the piping on location. The pipes are then made in our workshop and pressure tested.

Once the pipes have been tested, they can be installed in on location. The system is then ready for a final test.

In addition to installing new systems, we also help in repairing leaks or overhauling systems.

Result

Muns Techniek has already provided hydraulic piping for many projects. These projects vary from a small number of pipes on hydraulic winches, to the piping of large ships such as hoppers and split barges.

In our workshop we can bend hydraulic pipes up to 60mm. If necessary, these pipes can be equipped with bördel or cutting fittings.

Control system filling machine

Control system filling machine

Muns Techniek is a system integrator for Hydraulic systems and Electrical controls. With more than 25 years of experience we offer Hydraulic and Electric Solutions for projects in the Maritime, Offshore and Industry.

Customer

In this project Muns Techniek was asked to modernize the control of a filling machine. The controls were very outdated and a number of parts were no longer available. A significant part of the controls had also become redundant due to adjustments to the machine over the years.

Revision

When overhauling and modernizing the drive and control system, Muns Techniek replaced the outdated PLC, frequency drive and thyristor controllers with new models. This allows for the availability and replaceability of the components, both now and in the future.

Additionally, unnecessary components, sensors and cables have been removed, and the remaining sensors and cables have been renewed.

Benefits: Innovation

Revising the control system has the advantage that the machine is now future proof for a longer period. Because the unnecessary components have been removed, the two cabinets of the original control could also be integrated into a single cabinet, which makes the system more straightforward.

Result

The system has been cleaned up, modernized and updated. The control system has been simplified and placed into a new operating panel. Future adjustments can now be easily integrated into the new control. This will keep the control simple and uncomplicated in the future.

Custom made diesel HPU’s

Customer

Our client was in need of multiple hydraulic power units for the opening and closing of shut-off valves. The HPUs must meet customer specifications, be user-friendly and as compact as possible. Additionally, all components must be easily accessible for future maintenance.

Muns Techniek solution

To meet customer specifications, we designed an HPU with a simple three-cylinder diesel engine. The HPU is easy to connect to the intended valves using the supplied hydraulic hoses.

The HPU has simple controls, which allows the user to open or close the intended valves without much effort.

During use, the control panel also clearly displays the status of the HPU. This gives the user a good overview.

Result

The HPUs are
fully designed and assembled at our workshop in Sleeuwijk. They have been thoroughly
tested to ensure they meet the customer specifications.

Dredger repair

Dredger repair

Muns Techniek is a system integrator for Hydraulic systems and Electrical controls. With more than 25 years of experience we offer Hydraulic and Electric Solutions for projects in the Maritime, Offshore and Industry.

Customer

During operation, our customer’s dredger had sustained major damage and was in need of repair. The damage resulted in a flooded pumproom and severely affected hydraulics and controls. Muns Techniek was approached to repair and, where needed, revise the hydraulic parts of the system.

Muns Techniek solution

The flooded pumproom was cleared of major hydraulic components. These components were transported to our workshop and thoroughly checked and tested. If possible, components were repaired. Components that were not fixable, and components that had to be replaced because of revision of the system, were replaced.

In addition to the repair of the hydraulics, the hydraulic piping has also been replaced at the request of the customer.

Result

The system has been completely repaired and revised and the hydraulics have been restored to good working condition. The steel hydraulic piping has been replaced by stainless steel piping. Muns Techniek has rerouted the piping and moved it from the floor to the walls

A-Frames

Muns Techniek is a system integrator for Hydraulic systems and Electrical controls. With more than 25 years of experience we offer Hydraulic and Electric Solutions for projects in the Maritime, Offshore and Industry.

Customer

The customer’s vessel is equipped with two A-frames, each with two cylinders to move the individual legs of the frame. Our customer requested a solution to reduce the tension on the frame when the frame is moving.

Muns Techniek solution

To reduce the tension, both frames were equipped with equalizing valves. These valves reduce the speed of either cylinder when necessary. This keeps the frames straight and reduces tensions that would occur due to a difference in cylinder extension. The system is equipped with sensors. The feedback from these sensors is used to continuously correct the speed of the individual cylinders as necessary.

Result

The system works automatically, using the feedback from the sensors installed in this installation. The user can customize the settings of the system, allowing the user to set the limits and to a point control how the system should react to a difference in cylinder extension.

Subsea bomb detection

Subsea bomb detection

Muns Techniek is a system integrator for Hydraulic systems and Electrical controls. With more than 25 years of experience we offer Hydraulic and Electric Solutions for projects in the Maritime, Offshore and Industry.

Customer

In some waters it is not uncommon to find explosives in the soil. This can be a major problem for dredgers. Our customer asked our assistance to develop a system that was capable of finding these explosives, using a subsea magnetometer.

Muns Techniek solution

For this to work, the sensor will have to be near the soil at all times. This means that the sensor will have to be lifted and lowered depending on the changing water depth as the vessel moves along. Our engineers developed the hydraulic system and appurtenant controls to keep the sensor in the right position.

Result

The system is using winches to lower and raise the sensor into the water. Subsequently the sensor remains in the right position to search for bombs in the soil.

Muns Operating System, HMI Software

Muns Techniek is a system integrator for Hydraulic systems and Electrical controls. With more than 25 years of experience we offer Hydraulic and Electric Solutions for projects in the Maritime, Offshore and Industry.

Customer

In many of our previous projects that included software control and an HMI (Human Machine Interface), we ran into limitations of the HMI software. Often what we wanted to implement was either very difficult, or just not possible.

Additionally, when a customer wanted something added to their system, it happened that the software licence had to be upgraded. The additions would cause the HMI to exceed the limit of the current licence.

Muns Techniek solution

To ensure we did not have such issues in the future, our software engineers developed our own HMI software, the Muns Operating System software. Because the development is done in-house, we have complete control over the possibilities and extension of the software.

Benefits: Innovation

The advantage of our own software is that besides including the standard functionality of an HMI software, the software itself has been more specifically designed for our own systems. In addition, it allows us to add new functions when necessary.

Because the software is developed in-house, other software developed by our engines, such as the survey chart software, can easily be integrated. This ensures that the integrated software becomes a part of the HMI, instead of just a stand-alone program that is called upon by the HMI.

Result

This new software has now been installed in a number of our more recent projects. During the commissioning of the systems, the software has been thoroughly tested. This ensures that the HMIs of these systems are easy to use and work as intended.

Moonpool

Muns Techniek is a system integrator for Hydraulic systems and Electrical controls. With more than 25 years of experience we offer Hydraulic and Electric Solutions for projects in the Maritime, Offshore and Industry.

Customer

During the modifcation of an existing vessel a moonpool was incorperated in the ship. For the opening and closing of the moonpool doors, the customer wanted hydraulic cylinders and a appurtenant manifold. The cylinders and the manifold had to be easy to connect to the existing hydraulic system.

Muns Techniek solution

Muns Techniek designed the cylinders and the manifold completely according to the specifications of the customer. The manifold has the possibility to close the moonpool in an emergency situation. In order to make this possible, an hydraulic accumulator was included into the system.

Result

The manifold and cylinders have been tested extensively in our workshop by connecting them to the control cabinet of the customer. The system reacted as it should and cylinders can be moved according the commands issued by the control system.

HPU and Winches

Muns Techniek is a system integrator for Hydraulic systems and Electrical controls. With more than 25 years of experience we offer Hydraulic and Electric Solutions for projects in the Maritime, Offshore and Industry.

Customer

Our customer was in need of an HPU to control a number of winches. The customer already had an unused HPU with corresponding control cabinet, and winches that could be used. The HPU had never been used or tested, and the winches and HPU both needed to be revised and modified to fit the intended purpose.

Muns Techniek solution

Our engineers and mechanics overhauled and modified the HPU, and modified and tested the control cabinet. The electro motor of the HPU was replaced with a different one to meet the requirements, and specially developped valve blocks were added. The complete unit was mounted in a container for easy transportation.

The winches were also modified to better align with the requirements. The existing flexible hydraulic hoses were replaced with hard piping and valves.

Benefits: Innovation

As per customer request, the unit was designed in such a way that it can easily be integrated in their existing system. The unit was outfitted with specific hydraulic and electrical connection points for such a purpose. Additionally, a local control box was made that can control four winches separately. This control box easily connects to the outside of the container, if necessary.

Result

The containerized HPU is now suitable for the intended use. It is capable of controlling up to four winches simultaneously, and it can be connected to the existing system using the included signal cables. The winches can be connected to the HPU through the hydraulic connections on the outside of the container.

The local control box allows one operator to locally control the winches. Valves on the HPU and the winches allow the operator to use the winches in normal mode or in CT (constant tensioning) mode.
