QuantiCast Epoxy Resin Now Globally Available!




We are happy to announce that after the completion of extensive development and testing work, our very own epoxy resin compound is now globally available for purchase through the QuantiServ organization, starting from 01 January 2021 onwards.

The product is called QuantiCast. It was developed to suit a very wide range of applications in various industries. QuantiCast is an advanced chocking and grouting material for indoor and outdoor use.

This highly durable, non-shrinking material is characterised by high compressive and impact strength. It is absolutely non-poreous and is resistant to a wide range of chemicals, such as hydrocarbon fuel and lubricanting oils, solvents, sea water and many more.

Epoxy Resins that are to be used for marine applications do require classification society type approval. QuantiCast is type approved by DNV-GL and by Lloyds Register.

QuantiCast is priced very competitively. Do ask us for an offer!

Wrapping of a rudder shaft at QuantiServ Italy

New Video: Wrapping of Propeller Shafts and Rudder Stocks

Shaft wrapping is an activity that our specialists perform on a regular basis, mostly for new ships while they are under construction.

Whenever the design of a vessel mandates that the propeller shaft or rudder stock lies exposed to open seawater, then it should be protected against electro-chemical corrosion. This type of corrosion occurs in the presence of (sea-) water and air (or dissolved oxygen) and the usual way of avoiding it is to coat the shaft with a protective layer of fiberglass.

The following picture shows an example of a rudder stock showing severe signs of corrosion. This is the very outcome that wrapping prevents.

The wrapping process as such is very well established and the results are excellent. During dry docking, we have recently inspected some shafts that we have wrapped ten years ago. We found the wrapping in still perfect condition.

Witness here how our specialists are doing it:

Supplied Fifteen New Engines for Soil Sampling Drilling Rigs

QuantiServ, as the exclusive dealer for Deutz high-speed engines and spare parts in Hong Kong, has sold 15 new engines to Hong Kong’s premier construction company. The engines will be installed in soil sampling drilling rigs.

The first five drilling rigs were completed at the end of 2017 and have been taken into commercial use already. The next batch of three will follow in March 2018.

The engines have a nominal output of 58kW at 2300 rpm and a maximum torque of 273 Nm at 1500 rpm. They are compact, light weight and are thus very popular in agriculture, mining and construction machinery all over the world. They are Tier III compliant.

Our scope of supply consists of the following:

  • Engines, type Deutz D914 L04
  • Control systems
  • Installation of the engines and control systems into the newly fabricated drilling rigs
  • Commissioning and site testing

Protecting exposed rudder stocks with fiber glass

QuantiServ’s resin engineers are used to work on a very wide variety of equipment. They are equally versed in repair jobs as in new installation work.

The work shortly described here falls into the latter category. In December 2016 we received for fiber glass wrapping two rudder stocks from a multipurpose frigate currently under construction in an Italian shipyard. The shipyard used to carry out the wrapping by themselves, in the yard. But they lacked the expertise and the right equipment, so decided to give these two rudder stocks to QuantiServ for wrapping in our workshop in Genoa.

The work included the sandblasting of the area to be wrapped, the verification of the surface roughness, the wrapping and final coating itself, as well as the spark testing. The surveyor from the shipyard, who attended the whole process, appreciated the result and said that the speed as well as quality of the work was superior compared to the earlier ones done by the yard.

Because of the good service and result, the shipyard intends to have the next few rudder stocks done at QuantiServ Genoa too.

 

 

Rudder Stem Housing In-situ Machining on New Type of LNG Carrier

Rudder stem housing in-situ machining on a new type of LNG carrier

QuantiServ have a long-term and good cooperation with many newbuilding and repair shipyards.

Recently QuantiServ were requested to carry out in-situ machining (line boring) of a rudder stem housing on a new type of LNG carrier that is under construction in a Chinese shipyard. Our team were on-board to calibrate the inner diameter of the rudder stem housing and found that the ovality and parallelism were out of limit.

Thereafter, a laser alignment check of the rudder stem housing was done and the corrections to be made were calculated. Finally in-situ line boring of the rudder stem housing was carried out successfully.

A final check showed that the ovality, parallelism, roughness and centre line of the rudder stem housing were all within tolerance. The shipyard was very satisfied with our service and confirmed the final result.
