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 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

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

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 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 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 can be connected to the existing system using the included signal cables. 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.

Modified tensile tester

Modified tensile tester

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 had a functioning tensile tester that was in need of replacement of the HPU and control. The tester had worked for a long time, but started to show its age. With the replacement of the control system, the customer wished to upgrade the system to a more modern version.

Muns Techniek solution

To revise and modernise the HPU and control system, Muns Techniek replaced the existing system using two separate motors that were activated depending on the need with one motor operated by a variable speed drive. The previous components used for the regulation of the system were replaced by a PLC. The control panel has been upgraded to include a touchscreen panel with the Muns Operating System, our own HMI (Human Machine Interface) software.

Benefits: Innovation

The modernising and upgrading of the HPU and electric control has the advantage of making operation more controlled. The inclusion of the touchscreen gives the operator more information of the status and operation of the tensile tester.

Result

The system has been cleaned, modernized and upgraded. It now allows for more versatile operation and has added function, such as allowing for a number of pre-saved settings for different materials, that were previously not available.

Customized winches

Customized 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 client, a major contractor in the dredging industry, was looking for a winch for her dredging equipment. Everything that was available as standard in the market did not meet his requirements

Muns Techniek solution

Muns Techniek was approached and of course a solution was developed. Muns Techniek has also supplied several winches for various applications in the past. Customized and integrated with the hydraulic system that was already installed on board.

Benefits: Innovation

No major adjustments were needed on board, because the winch exactly met the demands of the customer. Full integration with the controls was also included.

Result

Customer was very satisfied, and has since ordered 3 winches from Muns Techniek. The customer realizes that they can entrust their technical challenges to Muns Techniek. Whether it’s a winch or a complete jack-up system, Muns Techniek delivers the solution.

Integration survey data

Integration survey data

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

Jack-up systems place the legs of a ship at the bottom of the sea. The strength of this soil has been partially mapped by so-called survey companies. The accuracy here is often insufficient, with the risk that the legs sink (too) deep into the seabed. During the positioning of the ship on the seabed, our customer was constantly bothered with necessary manual calculations to ensure the stability of the (standing) ship.

Muns Techniek solution

We were asked to propose a solution for this additional effort and since we saw this as a great challenge, we immediately started creating ideas. The result was a real-time visualization of the forces in the soil with respect to the penetration of the legs into the seabed.

Benefits: Innovation

Since the actual forces relative to the expected bottom strength are shown with a clear visualization, the captain has more certainty about the correct stability of the ship standing high on its legs on the seabed.

Result

Peace of mind at the customer because of the “real-time” image, and no more “stressful” calculations to check stability.

Integration hose reels

Integration hose reels

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

Jan de Nul has special winches on her WTIV “Vole au Vent” (hose reels) with hoses that transport jet water to the spud scans. This water serves to rinse the leg from the soil. Since the delivery of the vessel, there have been regular major failures with this system. Jan de Nul has asked Muns Techniek to make a proposal to make this part more reliable.

Muns Techniek solution

Our engineers have completely revised the controls of the frequency drives (VFD) and designed a new CT system. (CT = Constant Tensioning). In addition, we immediately integrated this sub-system into the existing HMI (development Muns Techniek). From now on, it is possible for the “hose reels” to move automatically (synchronized) with the jacking system.

Benefits: Innovation

As the new system has been extensively tested in our own workshop by means of a simulation, we were able to carry out commissioning in a relatively short period.

Result

Since our commissioning, the system has been operating fully automatically and without problems or issues. On board it saves 4 people who had to carry out the “hose reels” for this modification.
Nieuw, laatste zin: On board it saves local on the spot checking by 4 persons of the crew.

Re-activated Jack-up rig

Re-activated Jack-up rig

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 end customer owns an old jack-up rig that has been “cold-stacked” out of use for more than 4 years. As a result of changing market demands, our customer initiated to “activate” the rig again but with a different purpose. Muns Techniek was asked to perform a complete conversion of the hydraulic jacking system.

Muns Techniek solution

First of all, we replaced the old rusty piping on deck with new stainless steel piping. We then completely replaced the old operating system with modern components. A lot of wiring could be eliminated through a network of PLCs, and with the help of our (own development) Muns Operating System and HMI the jack-up rig can last for many years.

Benefits: Innovation

The latest techniques and technologies have been implemented. With the support of the internet we can, if necessary, offer full remote support to the crew.

Result

Customer was very impressed of the easy-to-use Muns Operating System and the user-friendliness of the HMI.
Commissioning was carried out completely in accordance with the pre-set time plan.
