LPG Tanker semi-refrigerated vacancies

 Semi-refrigerated type gas truck: features and characteristics, subtleties of employment

Among the many types of specialized vessels engaged in the transportation of liquefied gases, semi-refrigerated gas carriers occupy a special position. These vessels combine the ability to refrigerate cargo and maintain it under pressure, which makes them versatile in terms of transporting various types of gas. They are in demand in many regions of the world and provide stable logistics for the oil and gas, chemical and energy industries. Let's see how they differ semi-reefer gas carriers, what characteristics they have, and what specialists are required to work on board.

What's happened semi-refrigerated gas tanker?

Semi-reefer gas carrier is a specialized vessel for transporting liquefied hydrocarbon gases (LPG), ammonia, propylene and other chemical products. Unlike fully refrigerated ships, a combined method of storing cargo is used here: cooling to relatively low temperatures combined with maintaining pressure inside the tanks.This design makes it possible to transport cargo at temperatures of -11 – -50 °C and pressures from 4 to 7 bar. This is useful when transporting substances that do not require cryogenic conditions (such as LNG), but still require controlled cooling and stabilization.

Design features of the vessel

The basis of the gas carrier is cylindrical or spherical tanks (type C), made of durable steel and equipped with thermal insulation. The following systems operate inside each container:

• cooling;

• pressure control;

• emergency release;

• inert gas;

• fire extinguishing

The vessel is also equipped with pumping units that provide both loading and unloading and transfer of cargo between tanks. An important feature is the presence of gas detectors and alarm systems, which significantly increases safety on board.Semi-refrigerated vessels usually have moderate sizes (from 5 to 25 thousand cubic meters in capacity), which makes them convenient for working in ports with average infrastructure and on routes between developed industrial regions.

Advantages of vessels of this type

The main advantages include the following: 

1. Flexibility in operation: the ability to transport different types of gas without significant equipment modifications.

2. Cost-effective: Compared to fully refrigerated vessels, semi-refrigerated vessels are cheaper to operate.

3. Increased safety: pressure and temperature stabilization systems reduce the risk of leaks.

4. Compact dimensions: facilitate maneuvering in ports with limited water area.

Due to these advantages, such gas carriers are actively used for coastal and international transport between refineries, chemical plants and gas terminals.

Who works on semi-reefer gas carriers?

To operate the vessel, a crew who has undergone special training is required. In demand on board:

• captain and chief officers (control navigation, safety and work with dangerous goods);

• gas engineers (specialists responsible for the condition of tanks, cooling and safety systems);

• senior mechanic, watch mechanics, electromechanics (ensure proper operation of technical systems);

• sailors, boatswain, cook, ship electrician (service the ship on a daily basis).

Working on such vessels requires not only professional skills, but also strict adherence to international standards for handling hazardous substances.

Conditions of employment

To get into the crew of a semi-refrigerated gas carrier, you must:

• have a maritime education and a valid diploma for their position;
  undergo training under the “Gas Tanker Familiarization” or “Advanced Gas Tanker” program, depending on the position;

• have experience working on tankers or chemical tankers (desirable);
  have a good level of English, especially for officers;
  undergo a medical examination and have a full package of maritime documents (sailor's passport, certificates, safety certificates, etc.).

Sailors planning a career on such vessels must be prepared for strict discipline, attention to detail and high responsibility.
