Will the repair fit the window alongside?
The ship has a few hours alongside. Add the repairs and see, hour by hour, whether a Tecmarine® team can mobilise, get the permits, weld, cool and test before she sails — without off-hire.

About this tool
01 / 03What it is
A planning tool for repairs done afloat, alongside or at anchorage. It turns a repair job into an hour-by-hour schedule — mobilisation from Santos, port approval, gas free, hot-work permit, welding, cooling, NDT and tests — and checks it against the ship’s window in port.
How to use it
- 01Choose the port and enter the berthing and sailing times (ETA and ETD).
- 02Set how early the order is placed, the welding stations and one or two shifts.
- 03Add the repair modules: crack, insert plate, pipe spools or weld seam, with size, space and position.
- 04Read the verdict and the Gantt; save the PDF or send the plan to Tecmarine® for a quote.
Why it matters
- See before the ship arrives whether the repair fits the call — or how to make it fit.
- Avoid off-hire: the work runs during cargo operations instead of holding the ship.
- Start the quote with a plan the superintendent, the owner and the yard all read the same way.

Crew and man-hours

≈ 177man-hours on board
2 shifts · 24 h. Per shift: 6 people on the welding stations (2 × 3: welder, fitter and fire watch) and 1 supervisor. Plus 1 NDT technician.
Off-hire
Enter the daily hire to see how much off-hire a repair during cargo operations avoids.
The hire stays in this browser: it is not in the link or in the request.
Planning figures, not a quote. Real durations depend on the ship, the access, the terminal's rules and the class surveyor.
How the planner works
The planner turns the job into a schedule the way a repair supervisor would: who has to arrive, which papers have to be signed, which spaces have to be gas-free, how long each weld takes and how long it cools. Every figure is a planning assumption, written out below.
Mobilisation
From the Santos base: 4 h in Santos (call-out, equipment, gate access). Up to 700 km, by road: 5 h plus the distance × 1.3 at 60 km/h. Beyond, by air: 8 h, the flight, and 4 h to the ship. River ports +6 h, inland ports +2 h.
Port hot-work approval
Applied for when the order is placed: 2 h in Santos, 3 h at other sea ports, 4 h at river ports, plus 4 h when the work is next to a fuel tank (marine chemist's certificate).
Boarding
1 h for boarding, safety induction and the toolbox talk — never before berthing.
Gas free
Ventilation starts on boarding and the gas tester certifies the spaces one after another: open deck 0.5 h, engine room 1 h, cargo hold 1.5 h, ballast tank 4 h, next to a fuel tank 8 h. The permit on board follows in 0.5 h.
Welding
Full-penetration butt welds, both sides, manual FCAW: (0.0036·t² + 0.05) × 1.3 h per metre for a plate t mm thick, × 1.35 vertical and × 1.75 overhead. Cracks: gouged out at 1.5 m/h, then 0.8 × that weld time. Inserts: perimeter 4√A, cut at 4 m/h, bevelled at 6 m/h, fit-up 1.5 h + 0.5 h per m². Pipe joints: 0.012 × DN + 0.3 h each, two per spool.
Cooling and NDT
Cooling before NDT: 1 h up to 12 mm, 2 h up to 25 mm, 3 h above. One NDT technician takes each module as it cools: UT/MT at about 5–6 m/h; pressure test 1.5 h per pipe module.
Scheduling
Modules go to the first free welding station in the order listed. A fire watch stays 30 min after the last hot work, then 1 h to close the permits and clear the equipment. The plan fits when it ends before the release time.
Shifts and times
ETA and ETD are in port local time (UTC−3; Manaus UTC−4 — Brazil has had no daylight saving since 2019). With two 12 h shifts the work never stops. With one shift, work on board runs from 07:00 to 19:00: each later morning, 30 min renew the permit and repeat the gas test before the first arc. Boarding, permits, NDT and tests are never split across two days; cutting and welding carry on the next morning. Ventilation, cooling, mobilisation and the port’s approval go on through the night.
Crew and man-hours
On each shift, every welding station has 3 people (welder, fitter and fire watch), plus 1 supervisor; 1 NDT technician covers the whole job. Man-hours add up the crew’s hours on board, boarding to close-out — on one shift, only the shift hours and the close-out — plus the NDT hours. Travel is not included.
Off-hire
Off-hire avoided is the repair time on board, boarding to close-out, × the daily hire ÷ 24: what stopping the ship for this repair alone would cost, before deviation, pilotage and port costs. When the plan does not fit, it shows the cost of holding the ship for the hours past the release time. The hire never leaves your browser.
Q.01Is the result a quote?
No. It is a planning estimate built from the figures above. A quote follows a look at the job and the terminal's conditions — use "Request this plan" to send it to us.
Q.02Why does ordering before berthing change the result?
Because mobilisation and the port's approval can run while the ship is still at sea. With enough notice the team boards at berthing and the whole window goes into the work.
Q.03Why don't two welding stations halve the time?
Gas freeing, permits, cooling, NDT and tests do not get shorter with more welders, and one module stays on one station. More stations help when there are several modules.
Q.04What does "segmented along the coast" mean?
The work is divided between port calls: what fits now is done now, the rest at the next port — where a Tecmarine® team can meet the ship — or by a riding squad on board between the two.
Q.05Can I send the plan to the owner or the charterer?
Yes. "Save PDF" makes one A4 page with the verdict, the times, the chart, the modules, the crew and the man-hours; "Copy plan link" opens the same interactive plan. The daily hire is not in the link or in the request.
