A Clean OVID Does Not Win the Charter
Fuel, position, lay-up and the water tanks — what the tender scores after the inspection
Three ships, or five, or thirty, can all show a current OVID, a current eCMID and a DP trial that passed. One is cheaper. One is already in the right sea. One burns less fuel in DP. The client is hiring a month, not a folder.
Inspection rules, bunker prices and IMCA figures below are from the documents linked. Day rates and fuel burns marked as illustrations are arithmetic, not a noon report. The Taiwan wind job and the UK lay-up are types of fixture, not a named ship. This is not legal advice and not a promise that any vessel wins the next tender.

A Clean Report Gets You Read. It Does Not Get You Hired.
OCIMF’s Offshore Vessel Inspection Database has been the oil-and-gas folder since January 2010. A member commissions an accredited inspector. The questionnaire in force is OVIQ4, version 7300, from 21 April 2025. The operator may comment. Other charterers can buy the report. OCIMF is explicit that each recipient decides what it means. There is no stamp that says the ship may be chartered.
The inspector cannot commission his own visit. A submitting company has to adopt the request, and that request can sit for 14 days. No willing member means no fresh OVID, however current the class certificates are.
IMCA eCMID is a different question: a safety-management check by an accredited inspector, valid 12 months, shared so the next client does not repeat it. The operator chooses who sees it. A DP supplement can be attached. That anniversary is not the DP-trial anniversary.
An FMEA proving trial shows the failures match the FMEA. An annual DP trial shows the redundancy you are selling still works. IMCA’s clarification of M 190 separates them. You redo the proving trial when the design changes. You repeat, every year, the tests that show the protective functions still trip. Charterers want that report on the ship.
At the 2022 IMCA DP conference, a review of renewable-vessel inspection supplements — twelve of them — found that only a third had the DP trials report on board, and more than 40 percent were not in the station-keeping reporting scheme. Twelve is a snapshot. It is also what inspectors already find.
IMCA’s 2025 DP conference put numbers on the 2024 reports: 217 submissions from 169 vessels. Of those, 59 were incidents (position or heading lost), 115 were undesired events (the vessel was no longer single-fault tolerant), and 43 were observations. IMCA’s Impact Report says that total was 22 percent up on the year before. Main causes reported for 2024: thruster and propulsion 38 percent, power 24 percent, computers 11 percent, position references 11 percent. Human factors were the largest contributor to the position-loss events, and they were involved in more than half of the undesired events. Inside the human-factor reports the split was decision 38 percent, action 38 percent, memory 15 percent, sensory 9 percent. A passed trial does not answer any of that. The next tender asks whether you report.
The same report is why a silent safety year loses. IMCA members’ total recordable injury rate fell from almost 2.5 per million hours in 2011 to 1.1 in 2024. Offshore fatalities fell from 2.38 to 0.18 per million hours between 2007 and the latest figures in that report. Line of fire was the most common lost-time cause, 52 percent. A ship with no near misses and no station-keeping reports does not look perfect next to an industry that is writing them down. It looks asleep.
Divers polishing the propeller before vetting can take a little off the transit burn. They do not change the DP fuel curve, the cabins, or an eighteen-day mobilisation.
Fuel Is the Bid
On 22 October 2026 the Ship & Bunker Global 20 Ports Average for VLSFO was $919 a tonne. Hubs that day were not the same price. Use the index, then the port you will actually lift in.
IMO’s CII letter is the wrong scoreboard for most of this fleet. It covers the cargo and passenger types IMO listed, generally from 5,000 GT. A PSV, an AHTS or a construction vessel does not receive an annual A-to-E just because a tender mentions carbon. From 1 January 2025 the EU MRV does cover offshore ships from 400 GT, including support vessels, pipe-layers and drillships, on European voyages. The tonnes are reported. They are no longer a private argument.
What moves the bid is the power plant. A mechanical ship with controllable-pitch propellers can be the right hull for a long tow. Alongside a turbine, a seismic line or a drillship, those engines often sit at a poor load so the redundancy stays intact. A diesel-electric ship puts power on a bus and thrusters on motors. A battery lets one generator run where it is efficient and covers the DP spike. A CPP hull from a lower-cost yard and a diesel-electric hull with a battery, the arrangement many North European owners now tender, are not the same offer. The day rate that says the CPP hull is cheaper has not read the fuel clause.
A 2024 field study of a diesel-electric PSV (Applied Energy) used real load data and did not need a press release. Dispatching the generators properly cut fuel and CO2 by about 7–12 percent before any battery. Adding batteries took the full-mission saving to about 15 percent. Particulate matter fell much harder than the fuel. Treat 15 percent as that study’s ceiling for a whole trip, not a guaranteed DP peak.
Apply it to a planning burn of 10 tonnes a day in DP, which will not be your noon report. Fifteen percent is 1.5 tonnes. At $919 that is about $1,380 a day, about $248,000 over 180 DP days, before fewer running hours. A few thousand dollars of day-rate gap disappears if the charterer is paying the bunkers. If the project above you is a lump sum and the vessel is on a day rate, that fuel is your margin.
Methanol-ready and battery-hybrid lines are now normal on a new CSOV specification. The bunker barge is not. A ship that can burn methanol only on a coast with no methanol is a diesel ship. LPG as fuel is a gas-carrier practice, not the fuel of an AHTS, a survey ship or an SOV in 2026. LNG dual-fuel exists on some offshore support tonnage and still has to be lifted where the project is. Write the tender in the fuel the port actually has. Shore power matters for the same reason: port days should not be engine hours.
The Client Pays the Days You Spend Getting There
The vessel owner is usually selling days even when the contract above the ship is a lump sum. Working days, weather, standby, and the transit the client agreed to pay. A ship that is $10,000 a day cheaper and eighteen days further away is not cheaper.
Illustration. Ship A is $48,000 a day and two days from the field. Ship B is $38,000 a day and eighteen days away. Forty days on hire. The client pays mobilisation.
| Ship A | Ship B | |
|---|---|---|
| Day rate | $48,000 | $38,000 |
| Days paid (transit + 40 on hire) | 42 | 58 |
| Day-rate bill | $2.02 million | $2.20 million |
| Work starts | In two days | Sixteen days later |
Ship B is already about $188,000 more before bunkers. Sixteen extra steaming days at a planning burn of 12 tonnes, at $919, is about another $176,000. On a fifteen-day job, A is 17 × $48,000 = $816,000 and B is 33 × $38,000 = $1.25 million. The discounted ship lost.
Taiwan Wind: The Cable Does Not Wait
Taiwan offshore wind sits in strong current and a seabed that moves. Scour protection is a planned campaign. A cable that comes clear of the rock, in season, is not. The call goes to the vessel that can put rock down that month.
A Dutch owner had a split hopper and spent the money to turn it into a rock dumper: a fall pipe, DP good enough for the depth, a quarry it could load. When a Taiwan wind farm needed rock on exposed cables in the winter window, that hull could sail. Purpose-built ships that were excellent on paper were not in the Strait. The day rate on a scarce tool, in that season, is not the rate from the summer tender. Nobody needs the ship’s name to see the trade. The modification invoice, paid in a quiet month, is what made the yes possible.
The same logic is a battery container, a shore-power socket, or an inclined pipe for shallow water. Ten other ships will be available in spring.
The Client Is Also Buying the Beds
A service ship from about 2015 and a CSOV or walk-to-work ship from 2025 can both hold a gangway ticket. Newer ships are sold for large project crews, often on the order of 80 to 120 people, and many of them are technicians. A four-berth cabin and a galley laid out for forty shows up as missed rest and missed gangway hours. Feeding that shift is a capacity problem: range, stores, fridge, mess. MLC sets a floor for seafarers. It does not turn project crew into seafarers, and it does not enlarge the galley. The gangway earns its day only if people will live on board long enough to walk it.
Crew, Nationality and the Rate That Is Too Low
On project crew, and on most spot-market marine seats, the contract is the trip. People move from ship to ship. There is no irreplaceable rating in that market, and a full crew kept on wages all winter is an expensive way to insure a maybe. A cold ship is also not crewed by a phone call. Medicals, familiarisation and a DP certificate for this system take days. Keep the ship warm, in the region, with a small core who already know the DP, the crane and the client’s permits. Hire the rest when the fixture is real.
Tenders write language, medicals and local content in plain text. Some shelves want an OEUK or Norwegian medical on top of the flag medical. Taiwan wind has local-content rules. A dumped day rate with a crew the matrix will not accept dies in the first pass, and it pulls serious bids down while it dies. IMCA’s human-factor split is the commercial version of the same point: decision and action, not the thruster brochure, sit inside a large share of DP events. Familiarisation is a station-keeping number.
A Lower Rate Is Not a Reason to Sail
Taking the cheap fixture before the ship is closed up can cost the hull and the people on it. One anchor-handler had just left a yard and was sent across an ocean toward a charter that did not start for several weeks. The forecast already put a hurricane across the track. There was bunker enough to alter course. The passage plan the office accepted did not treat that as a reason to wait. Inspection covers on the anchor-handling gear had been shut after the yard and had not been proven tight. The ship met the storm. The engine room flooded. She sank. Fourteen people sailed. Three were taken off a liferaft two days later. Eleven were not.
A reduced day rate does not pay for the week skipped in the yard, and it does not pay for the route around the storm. If the only way to keep the date is to sail a hull you have not closed, the fixture is priced below the crew.
Same Fight, Different Vessel
Lump sum shows up above the vessel. The ship underneath is still burning days. Vessel type already decides pay. It also decides why the cheap ship loses.
| Vessel | What the day is for | What a clean OVID does not fix |
|---|---|---|
| Survey | Sensor time in the weather window. Quiet DP. | A noisy plant, a high DP burn, a multibeam the online surveyor does not trust. |
| Seismic | Hours on the line. The spread stays out. | Fuel, and a ship that cannot hold the line in the current. |
| SOV, CSOV, W2W | Gangway hours, beds, a galley for the shift. | A 2015 hotel on a 2025 job. Four-berth cabins. |
| AHTS | Bollard pull, then fuel on the tow and in DP. | A CPP plant that only looks cheap until the fuel clause. Position, if the rig move is this week. |
| PSV | Deck, bulk, fuel the platform will take. | Dirty tanks, no shore power, the wrong basin. Methanol-ready does not help if the port has diesel. |
| Drillship, semi, jack-up | Station-keeping and a stack that is already warm. | Months of reactivation. A water system that fails the sanitation certificate. |
| Cable-layer | Carousel, jointing spread, the trencher the route needs. | The right ship in the wrong ocean. A joint waiting on a vessel that is still weeks away. |
| Construction, heavy lift | Crane curve, DP3, deck, people. | Fuel in DP, mobilisation, a hotel that cannot hold the project crew. |
| Dredger, rock dumper | Cubic metres or tonnes a day, draft, rock size, a quarry in range. | A fall-pipe ship that cannot load, or a hopper that was never fitted to dump. |
Standby and ERRV boats sell being close and crewed. A dumped rate from a ship laid up a long transit away is not a safety boat.
Warm, Cold, or a Crew Sitting on the Wage Bill
- Hot, sailing crew, ready inside an hour. Machinery is live. You are paying wages for a ship that is not earning. Right when the product is the response: a term AHTS, a standby ship, a gap of days. Wrong as a way to sit the winter hoping.
- Warm. DNV describes hot lay-up as machinery kept running, and cold lay-up as machinery taken out of service. Owners use warm for the middle: a reduced crew, some systems still turned, humidity and the water system still on a routine. Back in days. This matches a freelance market. The core stays. The rest are hired against the fixture.
- Cold. Electrically dead except safety power. Humidity is the failure mode, so dehumidification is the work. DNV’s lay-up guidance puts recommissioning at three weeks or more, longer if the ship sat for years or the preservation was a padlock. The daily opex wins a spreadsheet and loses the fixture you cannot start.
Legionella multiplies in stagnant warm water: unused calorifiers, dead legs, a system nobody has flushed. UK port health samples for it when they issue a ship sanitation certificate under the International Health Regulations. The HSE offshore water guide treats it as a COSHH duty on installations: assess, write a scheme, monitor, or you do not have a water system. A DP trial will not see it.
One pattern is enough. A vessel came out of a long cold lay-up into a UK port because the charter wanted a sanitation certificate. The potable-water counts were high enough to hold her. Tanks and dead legs that have sat still do not come back over a weekend. She was still alongside weeks later. The fixture moved on. The OVID folder was not the document that stopped the ship. A planned maintenance system during cold lay-up is the water being turned over, not a binder for the next vetting.
Have the Other Ship in Your Head
A useful October is a ship that can change jobs without changing oceans. Rock instead of sand. One generator at a proper load instead of three at 20 percent. Warm in the basin nearest the work. A modification already paid, so a cable that comes bare on a Taiwan wind farm is a fixture.
The other October is a clean OVIQ4, a polished propeller, and a call you cannot take: eighteen days away, the wrong power plant, a water system last flushed on the previous charter. The day rate is what the crew see. The charter is the costs around it.
