A Guide to Working on LNG and LPG Carriers

A High-Stakes Maritime Industry

Gas ships, specifically Liquefied Petroleum Gas (LPG) and Liquefied Natural Gas (LNG) carriers, are specialized vessels crucial to the global energy supply chain. Their operation demands a high degree of expertise and stringent safety measures due to the volatile nature of their cargo.

The maritime industry thrives on the transportation of vital resources, and natural gas plays a starring role. This article dives into the world of Liquefied Petroleum Gas (LPG) and Liquefied Natural Gas (LNG) ships, exploring career opportunities, safety protocols, and the unique aspects of working on these vessels.

LPG vs LNG: Key Differences

Both LPG and LNG are natural gas in a condensed state, ideal for transport. However, there’s a key distinction in temperature:

  • LPG: Liquefied at around -40°C, LPG includes propane, butane, and other hydrocarbons.
  • LNG: Cooled to a staggering -160°C, LNG is primarily methane.

This temperature difference influences ship design and safety procedures.

The Crew’s Credentials: STCW and Medical Fitness

To ensure safe operation, gas carrier crews require specific qualifications under the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW). Bridge and engine officers need:

  • STCW Basic Training Certificates including fire fighting, survival at sea, and medical care.
  • Additional Endorsements specific to gas carriers, obtained through approved training programs.

Regular medical examinations are mandatory to ensure crew fitness for the demanding environment.

Steam Turbine Endorsement for Gas Carrier Engineers

Many gas carriers, especially larger LNG vessels, are equipped with steam turbine propulsion systems. This is due to the efficiency of steam turbines in converting the vast amounts of cold energy from LNG boil-off gas into propulsion power. As a result, engineers working on gas carriers often require a steam turbine endorsement in addition to their main engineering qualifications. This endorsement covers the specific knowledge and skills needed to operate, maintain, and troubleshoot steam turbine systems.

Medical Certificates for Gas Ship Crew

Seafarers on gas carriers must possess a valid medical certificate, as required by the STCW convention. However, due to the hazardous nature of the work, additional medical examinations may be necessary, focusing on:

  • Respiratory function: To assess suitability for working in low-temperature environments.
  • Cardiovascular health: Due to the physically demanding nature of the work.
  • Mental health: To ensure seafarers can handle the stress associated with gas carrier operations.

High Salaries in the Gas Carrier Industry

The gas carrier industry offers some of the highest salaries in the maritime sector due to several factors:

  • Hazardous working conditions: The inherent risks associated with handling flammable and explosive gases demand higher compensation.
  • Specialized skills: The required training and certifications make gas carrier officers highly skilled and sought after.
  • Remote and challenging working conditions: Long periods away from home and exposure to harsh weather conditions contribute to higher wages.
  • Demand for qualified personnel: The growing global demand for gas has increased the need for gas carriers, driving up salaries.

The Salary Divide: LNG vs. LPG

Compensation can vary between LNG and LPG carriers. Generally:

  • LNG: Tends to offer higher salaries due to the extreme low temperatures involved and the potentially larger size of the vessels.
  • LPG: May offer slightly lower salaries, but the demand for qualified personnel can be high, leading to competitive packages.

Working with Gas: Friend or Foe?

While working on gas carriers isn’t inherently harmful, specific precautions are crucial.

  • Strict adherence to safety protocols minimizes exposure risks.
  • Modern gas detection systems provide early warnings of leaks.

There’s limited risk of gas elements accumulating in the body during regular operations. However, immediate evacuation is necessary upon leak detection to prevent inhalation risks.

A career on a gas carrier offers exciting challenges, high earning potential, and the satisfaction of contributing to the global energy sector. With the right training and a commitment to safety, it can be a rewarding path for qualified individuals.

  1. With due respect, one who has worked in the production plant of these two gases can fit into their transportation with a little brush up training.
    I am seriously considering that journey again after my failed attempt the first time.
