Based on Experience

Based on many years of experience in the Norwegian maritime business, the company was originally founded in 2001 as an engineering consulting, project management provider, and inspection specialist in the cryogenic tank insulation field.

GTI has been involved in LPG/LEG/LNG projects worldwide and has a working established network in Japan, Germany, France, UK, Spain, UAE, Singapore, China, Korea, Nigeria, Norway, and the USA.

From 2010 we established a new head office in Hong Kong known as "GTI-Service Ltd". From 2013 to 2016 GTI formed a Joint Venture company in China called "Jiangsu Lanyu Insulation Technology, Co. Ltd" where GTI mainly focused on technology, design, and application. We created over 25 patents with Lanyu and several of them have achieved international acceptance and are in operation. Since 2019, the GTI group has focused on consulting services for demanding customers worldwide. We also take projects directly from shipowners or shipyards. Several new patents have been applied and become game-changer in its field. In 2020, we have established GTI-Shanghai that is a high-tech enterprise focusing much on research, class approvals, and 3rd party inspections.

We consist of a group of specialists with a large network of resources and experience in this field. We design cost-effective solutions and any of our products are designed to last the lifetime of the vessel with minimum maintenance.

GTI focuses on research and application of new insulation methods suitable for maritime environments.

We focus our ongoing research in the maritime market on the use of new proven materials and methods where the design will make the application easier.

The maritime market is conservative, however, it is also experienced. We aim to cooperate with clients and customers that value quality. Normally, we offer a five-year operational technical guarantee for our products.

Aerogels, vacuum systems, environmentally friendly PU Spray foam, reinforcements, and flexible mechanical outer barrier materials are our specialties.

We aim to deliver the lowest BOR in the market.

Insulation as Energy Conservation 

   Liquefaction of gases enables safer and more efficient storage and transportation, as it reduces volume over 600 times. It is commonly used in maritime transportation . To change a medium from a gas phase to a liquid phase, the media is deeply cooled. Huge super-coolers at refineries ensure the cryogenic temperatures required for producing the liquid phase of cargo's such as Liquid Natural Gas (LNG) at -163C, Liquid Ethylene Gas (LEG) at -105C and Liquid Petroleum Gas (LPG) at -46C.

LNG and LPG are recognized as clean energy sources and LEG is a major component in the plastic industry worldwide.

To be able to keep a liquified gas cargo cool and to maintain its liquid phase during transportation, adequate insulation is required. Insulation not only helps keep the cargo cold and tank pressure from rising, but also avoids cooling the ship's hull. Most common ship hull structures become brittle under -20C, and this can cause a ship hull structure to "break like glass". Insulation systems also reduce the risk of tank leakage, fire and explosion from these highly flammable cargoes. In recent years, environmental rules have also required a more green insulation solution.

Accordingly, any carelessness in cold insulation design and installation will cause huge problems for Liquid Gas Cargo ship operators. Heat is constantly transferred from energy sources ( Solar, Engine room, Ocean, Vibrations, etc. ) via radiation, convection and thermal bridging in materials.

 Huge amounts of vaporizing liquid from gas carriers and fuel tanks  can be saved every day by choosing the right materials and insulation system.

GTI’s mission is to avoid undue evaporation of your investment in cargo or fuel in a safe and cost-efficient manner.

Make the right choice.

To transport cryogenically cold liquids between tanks, adequate pipe insulation is required to avoid gassing in the pipe, maintain a rapid charging/discharging rate, prevent pressure build-up, and prevent ice formation and loss of cargo.

One of the main challenges in pipe insulation is the large thermal contraction and expansion of the pipe the insulation encases. Pipes are also almost always installed outside in harsh environments such as on ship decks and in seaside receiving terminals or compressor rooms with high temperatures and vibrations.

Pipe insulation is seldom more than 100mm thick and any carelessness during application and joining of pipe insulation segments can cause huge damage. Besides choosing the right materials, typical failures can include insufficient sealing of pipe insulation layers at insulation termination points and around gauges, lack of insulation contraction measures, poor workmanship, etc. A small crack in the insulation layers will allow humidity/water/seawater to enter into the insulation layers. Water will form ice that expands in a solid form and virtually "eats up" or crushes the insulation structure over time.

GTI has detailed experience in the design, manufacturing, and application of various cryogenic pipe insulation systems.

Pipe Insulation is often considered “low tech” and given little attention during the specification of new systems or repair projects, but it is anything but "low tech."

The cost impact and dangers of poor pipe insulation and supports can be much larger than expected any expected savings of "low tech."
