Independent maritime advisors with deep roots in commercial and technical shipping operations.
DECKTANK was founded and led by a team of gas professionals whose careers span sea service on LPG carriers at Chief Engineer level, technical management of VLGC fleets, LPG chartering advisory and senior executive roles in gas carrier shipping companies. DECKTANK is not a consultancy that advises on shipping from a distance. It was built by someone who has stood inside propane cargo tanks, coordinated Special Surveys in Korean yards, led TC chartering teams through volatile LPG market cycles and managed gas carrier claims on behalf of international Hull Clubs and P&I Clubs.
Our name reflects that foundation. A decktank is a working part of a vessel — functional, integral, not decorative. We bring the same approach to our advisory work: practical, precise, and built for purpose.
We operate as a fully independent advisory firm with no ownership links to shipowners, LPG brokers, cargo traders or financial institutions. In a sector where conflicts of interest are common — brokers with fixtures to close, managers with fleets to fill, banks with loans to place — this independence is our most valuable asset. Every IRR model we build, every TC negotiation we advise on and every cargo system we inspect serves a single purpose: your best interest.
Our primary specialism is LPG, LEG and NH3 shipping — VLGC, LGC, MGC, semi-refrigerated and pressurised gas carriers trading propane, butane, LEG, NH3 and VCM cargoes worldwide. This is a sector that requires a depth of technical, operational and commercial knowledge that generalist maritime advisors simply cannot provide. From propane cargo chemistry and IGC Code compliance to PDH market demand cycles and BLPG route TCE economics — LPG, LEG and NH3 is where DECKTANK lives — with broad expertise across LPG, LEG and NH3.
No financial relationships with brokers, shipyards, banks or lenders. Our only obligation is to deliver honest, unbiased advice. We tell you what we find — not what you want to hear.
Every recommendation is supported by rigorous quantitative analysis. We build detailed financial models, stress-test assumptions and present findings with the precision that high-stakes maritime decisions demand.
Shipping moves fast. Markets shift overnight. We work with urgency and clarity, delivering analysis on the timescales that real investment and operational decisions require.
Before fixing a VLGC, LGC or MGC on time charter, charterers need to know the true condition of the cargo reliquefaction plant — not just what the owner's survey says. We conduct independent, hands-on inspections of LPG reliquefaction systems on behalf of charterers prior to fixture — assessing compressor performance and mechanical condition, motor and cooling water system integrity, condenser and evaporator efficiency, safety relief valve settings, P&ID compliance with design parameters and overall plant capacity versus rated output. Our reports identify deferred maintenance, hidden deficiencies and foreseeable failure risk — giving charterers the technical leverage to renegotiate terms, impose condition precedents or walk away from a substandard vessel before signing the charterparty. This service draws directly on our team's direct experience as Chief Engineers on LPG carriers and CTOs of VLGC fleets, where reliquefaction plant management was a daily operational and commercial reality.
We provide independent Sale & Purchase advisory exclusively for LPG gas carriers — acting on behalf of buyers, sellers or their representatives at every stage of the transaction. Our S&P advisory covers market valuation and fair price assessment for VLGC, LGC, MGC and pressurised carriers, identification of suitable candidates from the active secondhand market, technical evaluation of class records and survey status, MOA negotiation support including Saleform terms and addenda, co-ordination of pre-purchase surveys and Idwal/condition inspection reviews, and post-completion delivery condition assessment. Unlike generalist S&P brokers, we bring direct LPG technical expertise to every valuation — understanding how reliquefaction plant condition, IGC Code certification status, 5th Special Survey proximity, EEXI/CII compliance and cargo system integrity affect true market value and post-acquisition OPEX. With over 37 years of LPG carrier experience including hands-on newbuilding supervision and fleet management, we ensure our clients see the full technical picture before money changes hands.
We provide full newbuilding supervision services exclusively for LPG and gas carrier construction projects — covering fully refrigerated VLGC and LGC, semi-refrigerated MGC, LEG bilobe Type-C, pressurised carriers and specialised gas units. Our supervision scope includes yard selection and contract negotiation support, steel cutting and keel laying attendance, structural and outfitting stage inspections, cargo tank fabrication and pressure testing, reliquefaction plant installation and factory acceptance testing, IGC Code compliance verification throughout construction, class survey co-ordination, sea trials attendance and delivery inspection. Our team has supervised the construction of more than 60 hulls over the last 20 years at leading Korean and Chinese shipyards — including 4 x 38,000 CBM fully refrigerated LPG carriers, 7 x 9,000 CBM semi-refrigerated LPG, 6 x 9,000 CBM LEG carriers and multiple bilobe Type-C tank units. This direct newbuilding experience means we know exactly where LPG carrier construction shortcuts happen, what yard claims look like and how to protect an owner's interests from steel to sea trials.
We investigate, evaluate and report on cargo damage claims and operational incidents involving LPG and gas carrier vessels — acting on behalf of P&I Clubs, underwriters, Hull & Machinery insurers, shipowners and charterers. Our claims services cover contamination and off-specification cargo investigations, reliquefaction plant failure and cargo temperature exceedance events, tank leakage and containment integrity incidents, cargo quantity disputes (B/L vs outturn), LPG vapour release and safety incident investigations, compressor damage and cargo system mechanical failure analysis, and Ship-to-Ship transfer incident assessment. We compile technical expert reports suitable for arbitration, court proceedings and settlement negotiations — drawing on direct experience performing gas carrier damage surveys for international Hull Clubs and P&I Clubs, and serving as Head Technical Advisor on gas claims for major European shipmanagement companies. Our reports are technically precise, commercially aware and prepared to the evidential standards required by P&I Clubs and marine insurers.
We provide a range of specialist operational and technical support services exclusively for LPG and gas carrier stakeholders. Vetting inspection support: we assist owners and managers in preparing for SIRE, CDI and private charterer vetting inspections on LPG vessels — reviewing SIRE records, identifying recurring observations, advising on corrective action and coaching officers on inspection readiness for gas-specific technical questions. Ship-to-Ship operations advisory: drawing on extensive LPG STS engagement experience at Eastern Mediterranean and other strategic anchorage areas, we advise on LPG STS operational planning, equipment requirements, mooring master briefing, compatibility assessment and risk evaluation for both VLGC and smaller gas carrier STS transfers. Expert witness and technical consultation: we provide independent technical expert opinions for maritime arbitration, P&I Club legal proceedings and commercial dispute resolution involving LPG carrier operations, cargo handling, reliquefaction system performance and gas carrier seaworthiness — to the standards required by English law maritime proceedings and international arbitration panels.

Technical fundamentals, regulatory framework, commercial structures and live market context — everything a ship owner, operator or investor needs to understand the LPG, LEG and NH3 shipping sector.
Gas carriers are specialised vessels designed to transport liquefied gases in bulk. Because gases occupy enormous volumes in their natural state, liquefaction — either by compression, refrigeration or a combination of both — dramatically improves transportation efficiency. Gas carriers are equipped with sophisticated cargo containment systems, temperature control equipment, pressure management systems and dedicated safety installations that distinguish them fundamentally from conventional tankers.
LPG is composed primarily of propane (C₃H₈) and butane (C₄H₁₀) — hydrocarbons that are gaseous at normal atmospheric temperature and pressure but can be liquefied by modest compression or refrigeration. LPG is derived from two sources: natural gas processing (approximately 60%) and crude oil refining (approximately 40%).
LPG is used across a vast range of applications worldwide: as a petrochemical raw material (propane dehydrogenation / PDH plants converting propane to propylene for plastics), as fuel for power generation, transportation, commercial and household heating, and as a clean energy alternative in developing markets where piped natural gas infrastructure does not exist.
Compared to heavy fuel oil, LPG significantly reduces emissions of CO₂, sulphur oxides (SOx) and nitrogen oxides (NOx), making it an important transitional clean energy source in the global decarbonisation pathway.
Ethylene (C₂H₄) is one of the most important petrochemical raw materials in the world — a building block for plastics, synthetic fibres, packaging materials, antifreeze and countless industrial chemical products. When transported by sea, ethylene is liquefied by cooling it to approximately –100°C at atmospheric pressure, requiring purpose-built, cryogenically capable cargo containment systems (typically bilobe Type-C pressure vessels). Ethylene is primarily derived from naphtha cracking in Asia and Europe, and from ethane cracking (using US shale-derived ethane) in the Americas. The growing US ethane export market has created a significant new trade flow for LEG carriers on the transatlantic and US-to-Asia corridors.
Other important petrochemical gases transported by LEG carriers include:
Ammonia (NH₃) is one of the most widely produced chemical compounds globally — approximately 180 million tonnes per year. Traditionally used as a raw material for fertilisers and industrial chemicals, ammonia is now attracting intense attention as a zero-carbon fuel — it emits no CO₂ when burned, and serves as an efficient hydrogen carrier for the emerging green hydrogen economy. When transported by sea, ammonia is liquefied at –33°C at atmospheric pressure, or alternatively kept in pressurised tanks at ambient temperature. Most LPG carriers designed for semi-refrigerated service are inherently capable of carrying ammonia — making the existing LPG fleet a critical infrastructure asset for the energy transition. The anticipated growth in green ammonia production and trade is expected to be a major driver of future MGC and LGC fleet demand.
Type A — Self-supporting prismatic tanks (fully refrigerated VLGCs). Require full secondary barrier.
Type C — Pressure vessel tanks (semi-refrigerated, pressurised). No secondary barrier required. Bilobe configuration common for LEG.
Cargo boil-off vapour is compressed, condensed back to liquid and returned to the tank. Consists of multi-stage compressors, inter-coolers, condensers and oil separators. Critical for maintaining cargo temperature and pressure during the voyage. Failure during a VLGC voyage can cost $500K–$1.5M in cargo losses and off-hire.
Gas carriers carry multiple redundant safety systems mandated by the IGC Code: gas detection systems, emergency shutdown (ESD) valves, pressure relief valves with documented setpoints, inert gas/nitrogen purging systems, water spray curtains, and dedicated cargo pump room ventilation. All systems require periodic class verification and certification.
Liquefied Petroleum Gas (LPG) is a mixture of hydrocarbon gases — primarily propane (C₃H₈) and butane (C₄H₁₀) — that are gaseous at normal atmospheric temperature and pressure but can be liquefied by modest compression or refrigeration. LPG is derived from natural gas processing and crude oil refining, making it a co-product of the global oil and gas industry.
| Property | Propane (C₃H₈) | Butane (C₄H₁₀) |
|---|---|---|
| Molecular Formula | C₃H₈ | C₄H₁₀ |
| Molecular Weight | 44.1 g/mol | 58.1 g/mol |
| Boiling Point (1 atm) | –42.1°C | –0.5°C |
| Vapour Pressure @ 20°C | 8.4 bar | 2.1 bar |
| Liquid Density @ 15°C | 508 kg/m³ | 579 kg/m³ |
| Calorific Value (lower) | 46.4 MJ/kg | 45.8 MJ/kg |
| Flammability Range (air) | 2.1% – 9.5% | 1.8% – 8.4% |
| Auto-ignition Temperature | ~470°C | ~365°C |
| Liquid/Vapour Expansion | 270:1 | 233:1 |
Both propane and butane vapour are heavier than air (specific gravity 1.5–2.0). Leaks accumulate in low-lying areas — bilges, cargo pump rooms — creating explosive atmospheres. Ventilation design of gas carrier compartments must account for this fundamental property.
Fully refrigerated VLGCs carry propane at –42°C and butane at –5°C at atmospheric pressure. Semi-refrigerated carriers operate at intermediate temperatures and elevated pressures. The choice of containment system determines cargo flexibility, operational cost and vessel value.
LPG (propane/butane) boils at –42°C to –0.5°C. LNG (methane) boils at –162°C. This fundamental difference drives entirely different containment technology, cargo handling systems, regasification equipment and crew certification requirements.
~60% from natural gas processing (associated and non-associated gas). ~40% from oil refinery by-products. Major producing regions: Middle East (Saudi Arabia, Qatar, UAE, Kuwait), US Gulf (fracking-driven growth), Russia (Yamal), North Africa, West Africa and North Sea.
Gas carriers are classified by cargo capacity and containment system type. Each system involves different trade-offs between cargo flexibility, capital cost and operational complexity.
The workhorse of global LPG trade. Fully refrigerated, bilobe or lobe tanks. Dominant on deep-sea USG–Asia and MEG–Asia routes.
Semi-refrigerated or fully refrigerated. Flexible cargo capability — LPG, ammonia, petrochemical gases. Regional and deep-sea routes.
Semi-refrigerated vessels serving regional distribution, coastal trades and niche petrochemical cargoes. High operational flexibility.
Cargo carried at ambient temperature under pressure. Simple technology, lower cost. Short-sea, coastal and river distribution trades.
Methane cargo at –162°C. Membrane (GTT) or spherical (Moss) tanks. FSRU units serve as floating regasification terminals.
3,500–6,000 CBM. European coastal distribution, gas bunkering support, terminal feeder services. Highly active short-sea market.
Traditional welded tank design. Used in fully refrigerated carriers. Requires full secondary barrier. Standard on most VLGCs.
Spherical independent tanks. Partial secondary barrier required. Better fatigue resistance. Used in some LNG carriers and older VLGCs.
Cylindrical or bi-lobe tanks. No secondary barrier required. Operate at elevated pressure. Standard on semi-refrigerated and pressurised carriers.
Gas carriers are among the most heavily regulated vessel types in international shipping. The International Gas Carrier (IGC) Code forms the cornerstone of the regulatory framework, supported by SOLAS, MARPOL and IMO environmental conventions.
The primary international standard for gas carriers. Mandated under SOLAS Chapter VII. Covers ship design, construction, equipment and cargo operations for ships carrying liquefied gases in bulk. The revised 2016 IGC Code (effective 2016) introduced updated hazard assessments and risk-based design approaches. All gas carriers built after 1 July 1986 must comply.
Incorporates the IGC Code by reference. Establishes flag state obligations for certifying gas carriers. Requires the issuance of a Certificate of Fitness for the Carriage of Liquefied Gases in Bulk — the primary operating certificate for all gas carriers without which no commercial employment is possible.
Regulates the discharge of cargo residues from gas carriers. Ammonia and certain petrochemical gases carried on multi-gas vessels fall under Annex II requirements. Gas carriers also fall under MARPOL Annex VI for air pollution control, particularly SOx and NOx emissions regulations.
In force from January 2023. EEXI (Energy Efficiency Existing Ship Index) is a one-time technical certification. CII (Carbon Intensity Indicator) is an annual rating (A–E) that assesses a vessel's carbon intensity per nautical mile. Gas carriers face specific challenges as aging VLGCs face CII rating degradation, restricting charterer acceptance and TC renewal potential.
Gas carriers must hold class maintained by a recognised organisation (LR, DNV, ClassNK, BV, ABS etc.). Class surveys for gas carriers are more complex than for conventional ships — tank inspections, cargo system function tests, safety system verification and in-service monitoring. 5-year Special Surveys for VLGCs are particularly intensive and expensive ($3–6M+).
Semi-refrigerated vessels carrying LPG alongside petrochemical gases (propylene, butadiene, VCM) may require dual certification under both the IGC Code and the IBC Code. This dual-certification capability significantly expands a vessel's cargo flexibility and commercial value.
Gas carrier operators must hold a valid Document of Compliance (DOC) under the ISM Code and each vessel must carry a valid Safety Management Certificate (SMC). Gas carriers operating at ports handling hazardous cargoes are subject to strict ISPS port facility requirements.
STCW 2010 Manila Amendments introduced mandatory specialised training and certification for officers serving on gas carriers. Officers must hold an Advanced Certificate in Gas Tanker Operations. This qualification requirement affects crew availability and cost, particularly for specialised gas carrier managers.
Fearnleys Weekly Report — Week 10 · 4 March 2026. All rates in USD/month unless stated. Source: Fearnleys AS / Fearnpulse.
EAST/WEST: The VLGC market showed continued firmness on USG–Asia corridors, supported by sustained PDH demand from Chinese petrochemical plants and an active freight enquiry programme out of the US Gulf. MEG supply routes remain partially disrupted following regional conflict escalation, redirecting cargo enquiries toward US and Algerian origins.
LGC and MGC segments improved week-on-week as regional distribution demand in Asia and Europe strengthened. Coaster rates in the European short-sea market remain supported by seasonal heating demand.

LPG seaborne trade is dominated by four key demand drivers: Asian PDH petrochemical production, Indian household fuel consumption, Middle Eastern refinery output and growing US export capacity driven by shale production.
Propane Dehydrogenation (PDH) plants convert propane into propylene for plastics manufacturing. China has over 30 operational PDH units with more under construction. These plants run to service debt obligations — making them price-inelastic, captive LPG buyers that sustain cargo demand even during LPG price spikes. PDH plants are the single most important structural demand driver for VLGC freight rates.
US LPG production from Permian Basin and Marcellus shale gas processing has grown dramatically since 2015. Enterprise Products Partners (Houston), Targa Resources and Energy Transfer operate major export terminals. +300 kbd of new US export capacity came online in 2026, fundamentally shifting the global LPG trade balance toward the Atlantic basin.
India's Pradhan Mantri Ujjwala Yojana programme has connected 90+ million households to LPG cooking fuel, driving structural import growth of 10–11% YoY in 2025. Indian Oil Corporation, Bharat Petroleum and Hindustan Petroleum are major importers. Indian LPG demand is relatively price-insensitive — government subsidies buffer end-consumer impact.
Approximately 28% of globally traded LPG transits the Strait of Hormuz from Gulf producers (Saudi Aramco, ADNOC, Kuwait). Regional geopolitical tensions create periodic supply disruptions that redirect cargo procurement toward Atlantic basin alternatives (US Gulf, North Africa), directly benefiting VLGC freight rates on non-MEG corridors.
The IMO's Carbon Intensity Indicator (CII) regulation, in force from January 2023, is reshaping the commercial landscape for aging gas carriers — affecting charterer acceptance, TC renewal prospects and vessel values.
Each vessel receives an annual CII rating based on CO₂ emitted per deadweight-tonne-nautical-mile. Rating is verified by class and reported to flag state. Required to improve by ~2% per year through 2030.
Vessels rated D for three consecutive years or E for one year must submit a corrective action plan. Major oil company charterers increasingly reject D/E rated vessels. TC renewal becomes difficult and rates compressed.
Vessels aged 23–27 years face CII rating degradation as engine efficiency declines and optimisation options narrow. This is a key risk factor in acquisition viability studies for second-hand gas carriers.
Most cost-effective near-term measure. Reducing service speed from 16 to 13 knots can improve CII rating by 1–2 bands. However, slow steaming reduces effective fleet supply and may conflict with TC performance obligations if minimum speed clauses apply.
EEXI compliance often requires an Engine Power Limitation device reducing MCR by 10–30%. This permanently restricts maximum service speed and must be factored into voyage performance calculations and TC negotiations.
Modern VLGCs can be retrofitted to burn LPG cargo as fuel (propulsion fuel — LPG ready). Several major VLGC operators have pioneered this conversion. LPG propulsion reduces CO₂ by ~15–20% vs HFO and eliminates SOx. Gas carriers using their own cargo as fuel have a natural decarbonisation advantage.
Ammonia (NH₃) is a leading candidate for zero-carbon marine fuel. Gas carriers — particularly those already handling ammonia cargo — are well positioned for dual-fuel ammonia propulsion. MAN and WinGD have announced ammonia-ready 2-stroke engines targeting gas carrier newbuilding orders.
Understanding the commercial structure of gas carrier employment is essential for owners, investors and operators. Key terms, common charter structures and market conventions are explained below.
Owner provides vessel + crew. Charterer pays hire rate (USD/day or USD/month) and covers voyage costs (bunkers, port costs). Fixed duration (6 months to 5 years). Most common employment type for VLGCs and LGCs. TC hire rate is the primary revenue driver in all acquisition models.
Owner provides vessel + crew + covers voyage costs. Charterer pays freight rate per tonne of cargo. Short-duration, single-voyage employment. VLGC spot rates quoted as USD/month equivalent for benchmarking. Higher risk, higher potential reward vs TC employment.
Owner provides vessel only — no crew, no management. Charterer is responsible for crew, insurance, maintenance and all vessel costs. Used for financing structures (Chinese banks, COSCO, leasing houses). BB hire is essentially debt-equivalent financing.
Agreement to carry a defined volume of cargo over a specified period using vessels of the owner's choice. Common for producers and traders with consistent cargo programmes. Provides volume certainty without vessel-specific commitment.
The daily or monthly rate paid by charterer to owner. For VLGCs: typically USD 1.5M–2.5M/month for 84,000 CBM vessels. 72,000 CBM vessels trade at a discount reflecting lower cargo capacity. Rate is the single most important variable in VLGC investment economics.
TC contracts specify a redelivery window (±30–45 days around the contracted end date). The redelivery position determines vessel availability for the owner's next fixture. Managing redelivery position against market rate trends is a key commercial skill.
Periods when the vessel is not at full charterer's disposal — drydocking, breakdowns, port delays beyond a defined threshold. Off-hire periods suspend hire payment. Charterers negotiate tight off-hire clauses; owners seek generous allowed off-hire provisions.
BLPG1: Ras Tanura → Chiba (MEG→Japan). BLPG2: Houston → Chiba (USG→Japan). BLPG3: Houston → Flushing (USG→Europe). These Baltic Exchange LPG routes are the primary TCE benchmarks for VLGC fixture analysis and freight derivatives hedging.
TCE = (Voyage revenue – voyage costs) / voyage days. Converts voyage charter freight into a daily rate equivalent for comparison with TC hire rates. TCE is the standard metric for comparing vessel earnings across charter types and routes.
Understanding the OPEX structure of a gas carrier is essential for evaluating acquisition economics, setting charter hire targets and assessing third-party management proposals. Costs below are representative of a modern VLGC (72,000–84,000 CBM) in 2026.
Officers and crew for a VLGC: typically 24–26 persons. Gas-qualified officers (Advanced Gas Tanker Certificate) command a significant premium — 15–25% above conventional tanker officers. Crew nationalities (Filipino, Indian, Greek, East European) significantly affect cost. Crew costs have inflated 6–9% annually since 2022.
5-year Special Surveys for VLGCs involve full tank entry, cargo system overhaul, main engine inspection and renewal of class certificates. Total cost: $3–6M+ for aging vessels. Survey scope and duration increase significantly after the 20-year mark. Unbudgeted Special Survey costs are the most common financial shock in VLGC ownership.
Annual OPEX for a VLGC typically escalates 5–8% per year as the vessel ages beyond 20 years. At age 25–27, maintenance and repair costs can increase by 30–40% vs. the Year 1 base. Any acquisition financial model must include a realistic OPEX escalation schedule — a flat OPEX assumption through a 5-year hold significantly overstates projected returns.
H&M (Hull & Machinery): typically 0.35–0.5% of vessel value per year, increasing with age. P&I (Protection & Indemnity): standard IG Club rates plus gas surcharges. War Risk insurance has escalated significantly with MEG regional tensions — currently adding $150,000–$400,000/yr for vessels transiting Hormuz-adjacent waters.
