Know How

STAINLESS STEEL WORK

PMG Shipyard is unprecedented for its excellent stainless-steel craftsmanship. Countless competing shipyards use them for their excellence and know-how for the conception of various custom-made spare parts.

The Shipyard can provide any drafting requirement, the conception and production of any type of marine stainless-steel part. The highly experienced Thai workers are trained to cut the profiles. Then, the stainless steel is bent and worked by hand polishing out any marks or bumps left by the machines to obtain the best possible finish.

Only Marine quality stainless steel 316L is used for all steel pieces such as handrails, hinges, spools or any other stainless-steel accessories. They are all hand-made on site by the machine operator using German specialized tools of the METABO’s INOX brand including the polishing discs, paste and other cleaning agents.

CARPENTRY

The people of Siam are famous world-wide for their extremely refined wood-working skills and PMG Shipyard has been applying this extraordinary craftsmanship to its high standards of cabinetry.

The art of marine cabinetry demands certain materials and essences such as Teak, Redwood, Asian Walnut, Ash, Oak, Mahogany, Jampa, Takhian Thong to name a few in order to accomplish various special veneers.

Considered to be one of the most precious woods, the Golden Teak is selected according to a specific level of criteria. At PMG Shipyard, only material which is certified “Natural Golden Teak” is used for the carpentry. In order to ensure longevity, the greens are selected in the ground.

The workshop is equipped with a wide variety of specialized professional European brand tools (Festool from Germany, Jet from Switzerland, and Makita from Japan).

FAIRING & PAINTING

There is nothing greater than personalizing a yacht with an original color, a specific design or special effect or adding a touch of gloss for a smooth mirror-like finish.

The most recent products have to be made with environmentally friendly bio-chemicals. These regulated products stop marine life from sticking to the hull.

The brand SIKKENS is the more commonly used anti-fouling system. Unlike most products used in Asia, SIKKENS is approved by Western ecological standards. Combined with the ancient method of fairing with long boards, it provides an indisputable protection against the elements. It is very labor intensive and requires great skill, but it is still the best way to achieve a perfect gloss mirror-like finish.

PMG was the first company in Asia to have switched from using high VOC (Volatile Organic Compounds) Paints to more Eco-Friendly paints such as PPG’s Envirobase. Regulations in Europe, America and Australia have already forced several companies to use these paints as they have a far less impact on the environment and they contain far less harmful contaminants than regular paints, are very durable and produce top quality finishes.

For Final coating applications we use PPG”s CERAMICLEAR Clearcoats on all painted and veneer surfaces as our final coating. This paint contains NANOPARTICLES that bead on the surface and produces a much longer lasting gloss. This type of paint has excellent chipping properties and forms a glass (ceramic) like surface.

VACCUM INFUSION

The hulls, decks and structural bulkheads are constructed by means of vacuum infusion with a core sandwich, using Bisphenol A-type Epoxy Vinyl ester resin known for their excellent corrosion resistance and anti-osmotic properties.

A light weight closed cell PVC foam core is used in order to allow for a well-controlled resin impregnation of the entire structure during the infusion process, giving optimum weight, insulation, stiffness and acoustic properties.

Bellow the waterline the laminate is built up with Soric fabrics to allow for a solid bottom.

The structure is comprised of several types of Multi-axial fabrics, each with unique advantages to enhance the structural properties.

The “impact zones” have been especially addressed:

The hulls are infused with Soric core below the waterline to give a solid bottom for greater strength and impact resistance, in turn also allowing the vessel to be beached in the event of an emergency.
The fore-peaks are watertight with collision bulkheads and foam filled to maximize the hull integrity and buoyancy of the vessel in case of frontal impact
The aft compartment is closed with a watertight bulkhead to protect the engine compartment in the event of flooding.

Improved productivity through significant time savings, particularly with large parts.
Improved working conditions for shipyard staff and a further step forward as part of the sustainable development policy in place at the yard. The technique does not release any volatile organic compounds (VOCs). It contributes to improving the working environment for shipyard staff and reduces production waste.
In addition to the excellent mechanical qualities achieved, the hull weight is kept under control, which in turns means optimal boat speeds.

“First of all, the end product is stronger,” he says.

“To achieve the best mechanical properties, the typical resin content of a composite is 30-35% by weight.

The vacuum infusion process helps us achieve this by reducing the amount of resin, leading to a relatively higher fibre content.”

Still on the subject of strength, the vacuum infusion process can be combined with foam cores for more advanced laminates.

This greatly increase stiffness for a low weight penalty.

“Cores enable bigger panels, less internal stiffening and so a clearer internal layout. They are also better at absorbing impact damage.”

“Secondly, it produces even lighter products.

The fibres that we use with vacuum infusion are much more mechanically efficient compared to the chopped and woven fibres used in the classic hand lamination process.

Therefore, we require less fibre, as well as less resin, which leads to even greater material and weight savings for the same strength.”

This lightness has an impact on efficiency and speed:
“Operators can attain higher speeds, or carry more cargo with the same power and fuel consumption. Alternatively, they can decide to use smaller engines, or use less fuel for the same speed.”
