CO2 Tanker Careers: The Emerging Maritime Role You've Probably Not Considered Yet

A New Trade, a New Fleet, and Not Enough Experienced Crew to Fill It

The first commercial carbon capture and storage (CCS) shipping operation in the world, Northern Lights in Norway, began regular CO2 transport in 2024. BIMCO published CO2TIME 2026 in May 2026 — the first dedicated standard time charter party for liquefied CO2 transport — a signal that the trade has matured enough to need its own contract framework. The global pipeline of CCS projects requiring maritime CO2 transport is growing.

The supply of seafarers who understand LCO2 (liquefied carbon dioxide) vessel operations is extremely limited. That gap is an opportunity — but it needs to be understood clearly before acting on it.

What CO2 Transport Actually Involves

Liquefied CO2 is transported at approximately -25°C and 20 bar pressure — conditions that place it in the category of liquefied gas tanker operation, similar in principle (though not identical) to LPG transport. CO2 carriers are purpose-built pressurised vessels, typically smaller than LNG carriers but operated under the same gas tanker regulatory framework.

The current CO2 carrier fleet consists largely of vessels adapted from LPG carriers or purpose-built for the CCS trade. Ships in operation include those used by Northern Lights JV in Norway, operated by Knutsen OAS Shipping on behalf of the JV partners (Equinor, Shell, and TotalEnergies). These vessels transport CO2 captured from industrial sources in Belgium and Denmark to the Sleipner and Eos reservoir formation under the North Sea seabed.

The operational demands on crew involve:

• Cargo management of pressurised liquefied gas at sub-zero temperatures
• Tank pressure and temperature monitoring throughout loading, passage, and discharge
• Regasification handling during injection at the offshore terminal
• Emergency response for CO2 leak scenarios — CO2 is an asphyxiant, not flammable, which changes the emergency response profile compared to LPG or LNG
• Compatibility management: CO2 is an industrial product with specific impurity tolerances that affect injection compatibility — cargo specification knowledge is required

The BIMCO CO2TIME 2026 Charter Party

The publication of CO2TIME 2026 by BIMCO is a significant marker of the trade’s commercial maturity. BIMCO produces standard form contracts for well-established trades — SHELLTIME for oil tankers, GASVOY and GASTIME for gas carriers, BARECON for bareboat charters. CO2TIME is the trade’s equivalent for liquefied CO2 time charters.

For seafarers, the existence of a dedicated charter form matters because it signals that operators, insurers, and cargo interests are committing to the trade as a long-term commercial activity rather than a pilot project. When BIMCO writes a standard form contract for a trade, that trade has reached commercial scale.

Which Companies Are Building CO2 Fleets

Northern Lights JV (Equinor, Shell, TotalEnergies)

The world’s first commercial CCS transport operation. Vessels operated by Knutsen OAS Shipping. The first phase uses two purpose-built CO2 carriers; expansion phases are planned as capture facilities across Europe connect to the Eos storage site. website: northernlightsccs.com

Hoyer Maritime

Danish gas tanker operator with CO2 transport capability. Hoyer has been involved in the development of CO2 transport concepts and operates pressurised gas tanker tonnage suited to the trade.

Larvik Shipping

Norwegian operator with a fleet of pressurised gas tankers including CO2 carriers. Active in the Northern European short-sea CO2 transport market.

UK CCS Projects Coming Online

The UK has several large-scale CCS clusters at various stages of development that will require maritime CO2 transport:

• East Coast Cluster — Teesside and Humber industrial CO2 capture projects, with offshore storage in the Southern North Sea
• HyNet North West — CO2 from industrial sources in Cheshire and Merseyside, stored in Irish Sea formations
• Acorn CCS — St Fergus, Scotland — using existing North Sea pipeline infrastructure

These projects will require their own vessel capacity, creating demand for UK-based maritime CO2 transport operations — and for crew with gas tanker and CO2-specific experience.

Qualifications: What You Need

Advanced Gas Tanker Training — Gas Carriers (STCW V/1-2)

This is the foundation qualification. STCW Regulation V/1-2 covers the advanced training required for Masters, officers, and ratings with designated safety duties on gas tankers, including LPG and LNG carriers. CO2 tanker operators universally require this qualification as a minimum for cargo-handling roles.

UK approved providers for Advanced Gas Tanker Training include Warsash Maritime Academy and South Tyneside College Maritime, among others. The course is typically 3-5 days.

Basic Gas Tanker Training (STCW V/1-2 Basic)

Required for ratings and officers not directly responsible for cargo operations but serving on gas tanker vessels. The stepping stone to the advanced qualification.

CO2-Specific Familiarisation

Because CO2 presents different hazards from conventional LPG (primarily asphyxiation risk rather than fire/explosion risk), operators running dedicated CO2 carriers typically provide vessel-specific familiarisation training. This is not yet a separate formal qualification — but documenting any CO2-specific training you receive will be valuable as the qualification framework develops.

Why Now Is the Right Time to Position Yourself

The CO2 tanker fleet is still small but growing fast. The qualification requirements are clear (gas tanker training), the operational experience base is very limited (because the trade barely existed five years ago), and the companies building fleets are well-funded, backed by major energy companies, and committed to long-term operations.

For gas tanker officers looking to diversify, or for experienced seafarers on LPG tonnage looking for a move into a growth niche, CO2 carriers are worth targeting specifically. Get your Advanced Gas Tanker Training in place if you don’t already have it, research the Northern Lights JV operators and UK CCS project development timelines, and note CO2 tanker interest on your Crew Connect profile so operators can find you as fleet expansion creates recruitment demand.
