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.

Jack-up system for a working platform

Jack-up system for a working platform

Muns Techniek delivers another jack-up system for a working platform

For one of our customers in the Netherlands we are proud to have delivered another jack-up system. The system consists of hydraulic jacking cylinders, capable of elevating about 1000 mT. The hydraulic power unit is diesel driven (2x 180 kW) and the maximum speed during lifting is 2,0 m/min. The barge and also the jacking system is classified by Bureau Veritas.
Complete electric control is engineered and made by Muns Techniek. The in-house designed HMI (Human Machine Interface) is easy to operate and will give the jacking operator all the necessary information for lifting the barge safely in water depth of up to 30 meters.

Increased lifting capacity Aeolus van van Oord

Muns Techniek increases lifting capacity of van Oord’s Aeolus

With the recent modification of the Aeolus, where the crane capacity was increased to 1.600 tonnes and the accommodation was expanded to 99, the vessels jacking capacity also needed an upgrade.
As Muns Techniek is the original supplier of the jacking system, we were asked to perform this important part of the vessels modification. After a long preparation period that included a lot of engineering, reviewing of material specifications and software modifications Muns Techniek was able to deliver an upgraded system. The new system is capable of lifting an increased total weight, which is 40% heavier compared to the original design. The major part of the modification is due to intelligent control software. This is one of the known unique selling points of Muns Techniek.

At Muns Techniek we are proud that due to the good cooperation with the project team at van Oord the harbor and sea trials for the jacking system went according to the pre-determined commissioning planning. We would like to thank van Oord for giving us this opportunity and the professional team work. And of course, we wish the crew a safe journey and success at the Norther OWF project.
