On 26 June 2025, ship recycling stopped being a matter of conscience and became a matter of law everywhere. The Hong Kong International Convention entered into force that day — sixteen years after adoption —...

Sound is how the ocean sees. Whales, dolphins, fish, and even lobsters rely on hearing to communicate, find food, avoid predators, navigate, and reproduce — and into that acoustic world, commercial shipping...

Onboard carbon capture is the most pragmatic idea in shipping decarbonisation: rather than wait for green fuels to become available and affordable, capture the CO2 from a conventional ship's exhaust before it...

Ammonia is the alternative fuel with the strongest long-term case and the hardest near-term problems. It contains no carbon, so it emits zero CO2 when burned, and made from renewable hydrogen it can cut...

Methanol has moved faster than any other alternative marine fuel from concept to commercial reality, and the reason is practical: it is a liquid at ambient temperature and pressure, so it sidesteps the cryogenic...

Sewage seems like one of the more mundane waste streams on a ship until an inspector asks to see the discharge records, and the rules turn out to be precise, distance-dependent, and unforgiving of guesswork....

For a technical superintendent, the Ship Energy Efficiency Management Plan is no longer the box-ticking document it once was. Since the Carbon Intensity Indicator took effect, the SEEMP has become the...

A container ship sitting at berth for two days with its auxiliary engines running is burning fuel and pumping out emissions the entire time — and a striking share of port-area pollution comes from exactly...

Everyone agrees that automating marine admin saves time, but "saves time" is not a number a budget can be built on. The reason AI document and admin automation often stalls at the proposal stage is that the...

A fleet manager's day is full of questions that should take seconds to answer but routinely take an afternoon. Which vessels are overdue for maintenance? Which burned the most fuel last quarter? Whose...

Marine inspection is being rebuilt around artificial intelligence, and 2026 is the year the gap between AI-equipped fleets and the rest becomes decisive. The leading platforms no longer just digitise a paper...

An audit trail is the difference between a record an inspector trusts and one they question. When a class surveyor, flag-state examiner, or Port State Control officer reviews a vessel's logs, they are not just...

Every engineer knows the temptation, and every chief engineer knows the risk it creates. At the end of a busy watch, with maintenance running over and the relief due, the logbook gets filled in haste —...

Fuel theft at sea rarely looks like theft. There is no broken lock or missing cargo — just a delivery that was a little short, a consumption figure that runs a little high, a transfer that does not quite...

Two sister vessels on the same route, carrying the same cargo, can burn markedly different amounts of fuel — and without analytics, nobody knows why, or which one is the problem. That gap is where the savings...

Fuel is the single largest controllable cost on a commercial vessel, often a quarter to a third of total operating expense — and for most fleets the data describing that spend arrives days or weeks after the...

A fleet's procurement function is where millions of dollars and the availability of every vessel meet — and in 2026 the software running it has become the deciding factor in whether that spend is controlled or...

A critical spare runs out the same way every time: quietly, while everyone assumes there is still one on the shelf — until an engineer opens the locker mid-repair and finds it empty. What follows is the...

The gap between needing a part and ordering it is where marine procurement quietly bleeds time and money. A requisition raised onboard waits for an email reply, a quote sits unopened, an approval bounces between...

Every marine maintenance job has a true cost, and on most vessels that cost is a guess. The labor hours get rounded or reconstructed from memory at month-end, the parts get pulled from the storeroom without a...

Most fleets know their total maintenance spend to the dollar — and almost nothing about where it actually went. The annual figure arrives from accounting, accurate and useless, because it answers the wrong...

A planned maintenance system is not just good engineering practice on a ship — it is a regulatory requirement woven into the fabric of how a vessel stays in class and keeps trading. Under the ISM Code, every...

No amount of preventive planning eliminates breakdowns entirely. A bearing lets go on a laden passage, a generator trips in heavy weather, a hydraulic line bursts during cargo operations — and when it happens,...

Some shipboard tasks do not care how many hours an engine has run — they come due on the calendar, and they come due whether you are ready or not. Statutory drills, safety-equipment servicing, certificate...

A marine diesel engine does not wear out by the calendar — it wears out by the hour. A main engine pushing through a long laden voyage accumulates wear at a completely different rate from an auxiliary that...

Preventive maintenance is the single biggest lever a fleet has against unplanned downtime — and unplanned engine failure alone can swallow 10 to 30 percent of a vessel's operating expense once charter...

A 24-vessel fleet trading internationally tracks more than 1,200 individual deadlines per year. Each vessel carries 50 or more statutory certificates with their own expiry dates. Each vessel runs an annual ISM...

Maritime regulation in 2026 moves faster than any operator's spreadsheet can track. IMO MSC and MEPC committees adopt amendments at every session. IACS publishes Unified Requirements and Unified Interpretations...

Liberian Maritime Authority Notice 003/2026 launched a Concentrated Inspection Campaign on Machinery and Electrical Failures — the latest signal that 2026 PSC focus is squarely on the engine room. SOLAS...

Hull integrity is the single largest steel asset on a vessel — and the single most expensive failure mode. The Enhanced Survey Programme (ESP), mandatory for bulk carriers and oil tankers under IACS Unified...

SOLAS Chapter V Regulation 26 is unambiguous: every vessel must check and test all machinery within twelve hours before leaving port, and the fact must be recorded in the Deck Logbook. US 33 CFR 164.25 carries...

The minute an incident happens on a vessel, the operational record being created determines what happens for the next twelve months — insurance claim, ISM Code investigation, MAIB or USCG report, charterer...

A vessel defect that lives in a logbook note, an email to the office, and a line in the next handover report is a defect that will resurface as a PSC deficiency, a class survey finding, a charter dispute, or an...

Every commercial vessel sails under a Minimum Safe Manning Document issued by its flag state administration under IMO Resolution A.1047(27) Principles of Minimum Safe Manning, with the MSMD valid for a maximum...

The first three things a Port State Control officer asks for when boarding a vessel in 2026 are the crew list, the certificate file, and the rest hour records for the last month. In under ten minutes she knows...

The marine insurance landscape that closes the 2026 fiscal year is structurally different from the one that opened it. February 20, 2026 saw the International Group P&I renewal conclude in the 5% range with...

The financial truth of running a commercial vessel in 2026 is that the bill arrives daily — whether or not the ship moves, whether or not it carries cargo, whether or not the charterer pays on time. Drewry's...

Modern fleet operators are converging on a question that did not exist as a unified metric a decade ago: what is the health of every vessel in my fleet, right now, on a single screen? The answer used to live in...

The fleet operator who walks into 2026 without real-time KPI monitoring is walking into a year where EU ETS now covers 100% of eligible emissions, FuelEU Maritime begins active enforcement with the first...

The maritime CMMS landscape entered a new phase in 2026. Verified Market Research's Q1 2026 analysis identifies four converging forces driving rapid transformation: regulatory compliance pressure (SOLAS...

For the UK workboat sector, the most consequential inspection deadline of the decade arrives on 13 December 2026. After three years of phased transition, vessels still certificated under the...
