Our business

We operate a versatile small-scale fleet of five ethylene capable vessels and one semi-refrigerated vessel as a vital part of the supply logistics value chain for liquefied gases.
HarpainGas carriers have been crossing the oceans for nearly three decades, resulting in profound experience and expertise in the handling and transportation of liquefied gases around the globe.

We live our corporate values: highest safety standards, technical excellence and mutual trust.

What we do

Our carriers serve the growth markets of liquefied petroleum gas (LPG), ethylene, ethane and ammonia. As a renowned enabler of safe and efficient transport and handling we are committed to the integrity of clean oceans and the environment.

We maintain outstanding quality and safety records by our firm zero-tolerance policy regarding incidents or breaches. Professionalism and passion have always distinguished us.

Our in-house ship management team offers solution-oriented handling expertise, as well as the highest quality and safety standards in seaborne gas transportation. The teams on board and ashore make the difference. Our comprehensively trained people provide all the gas logistics services necessary for the enduring success of our customers.

5 Ethylene Vessels, 1 Semi-Refrigerated Vessel

Our ships

Our vessels are able to carry a range of gaseous fuels, including ethane, ethylene and LPG, in the form of propane, butane, propylene and ammonia, and are contracted for spot and time charters.

Changes between products create new opportunities. LPG gases have a boiling point at temperatures between -104°C for ethylene and -0.5°C for butane. Varying low temperatures are achieved by pressure, refrigeration or a combination of both. Our versatile fleet provides all the key physical features and tailor-made cargo handling systems desired by our customers. Our highly professional staff are able to deliver customized solutions for every single voyage.

Our products

We are focused on finding transport solutions for the ambitious markets of liquefied gases. LPG, which ranks among the least-polluting fossil energy sources known in the world today, is classified for bridging technologies on the way to decarbonization of energy and industrial systems. Ethylene is one of the world’s most important chemicals and a key raw material for the plastics industry.
Ammonia is the main source of nitrogen, which is essential for plant growth and crucial for the world's agricultural industry.

Ammonia

Ammonia is a compound of nitrogen and
hydrogen, which is produced mainly on the basis
of natural gas. Ammonia is needed for fertilizers and
as a refrigerant in cold storage industries, as well as
widely used in many industrial processes. Ammonia
has a boiling point of –33°C and can be transported
on all of our vessels.

NH3

Ethane

Ethane is the second-largest component of
natural gas following methane. It is isolated on a
large scale or is a by-product of petroleum refining
and mainly used in the chemical indust- ry for the production of ethylene. Ethane has a boiling point of –88.5°C. It must be refrigera- ted to a low temperature, compressed to a high pressure or have both pressure
and temperature controlled in order to maintain it
in a liquid state. Our ethylene-capable vessels
are suited to the carriage of ethane.

C2H6

Ethylene

The annual production of millions of tonnes
of ethylene represents a vital part of the global
chemicals and plastics value chain. It provides the
raw material for textiles, electronic devices, automotive
parts and many other goods needed for widespread use throughout the world. It has a boiling point of –104°C.
Our sophisticated ethylene-capable fleet of
five vessels is our core business.

C2H4

LPG

LPG is a mixture of propane and butane and,
as a by-product of natural gas processing or oil
refining, rich in energy. LPG is used for heating,
cooking or powering cars, a feedstock for the production
of chemi- cals, a green fuel for farmers and growers and much more. Propane-based LPG is compressed into space that is 274 times, and butane 233 times, less than its
gases would occupy, with boiling points of –42°C and
–1°C respectively. All of our vessels can efficiently
carry LPG at varying temperatures.
