Planning Intermediate and Special Surveys in Eastern Indonesia
Surveys in eastern Indonesia do not overrun because the vessels are bad. They overrun because
nobody planned the access, the documents or the surveyor’s travel. A passenger vessel working Raja Ampat can complete
an intermediate survey inside a normal docking window — but only if the preparation starts three months out, not three days
out.
The cycle, in plain terms
A classed vessel runs on a five-year cycle. Annual surveys confirm the vessel remains broadly as classed. The intermediate,
falling around the middle of the cycle, goes deeper — typically including underwater examination and more internal inspection.
The special survey at five years is the heavy one: extensive opening-up, thickness measurement, tank internals, machinery
opening and a full review of the structure. Statutory and flag inspections of safety equipment, firefighting and lifesaving
appliances run alongside on their own schedule.
The practical implication for an owner is financial as much as technical: year five is expensive and it is entirely
predictable. Funding it across the four preceding years is the difference between a planned docking and a crisis — covered on
the budgeting page.
A three-month timeline that works
Twelve weeks out
Confirm the survey due window and the class or flag requirements that apply to your vessel’s service. Contact the society
and establish surveyor availability — in eastern Indonesia this is the binding constraint, because attendance means travel to
Sorong. Book the slipway or dock around the surveyor’s window, not the
other way round.
Eight weeks out
Agree the opening-up scope in writing: which tanks, which spaces, which machinery items, what will be accepted as evidence
for previous repairs. Order long-lead parts against the likely renewal list. Start assembling the document pack.
Four weeks out
Confirm staging, gas-freeing arrangements and insulation removal. Confirm the thickness measurement operator. Complete
outstanding conditions from the previous survey — arriving with open conditions turns a survey into a negotiation.
Survey week
Vessel on the hard, spaces open, documents on the table, machinery components open rather than reassembled, and somebody
technically competent accompanying the surveyor throughout. That last point matters more than it sounds: a surveyor walking a
vessel alone will write down what they cannot verify.
The document pack
Assemble it before the surveyor lands. Typically: registry and tonnage documentation; current class and statutory
certificates; previous survey reports and any outstanding conditions or memoranda; stability information; repair records and
material certificates for previous structural work; coating records; machinery history and running hours; crew certification;
safety-equipment service records; and port and syahbandar clearance for the docking movement.
Foreign-flagged vessels add temporary import status, cruising permit and agent coordination. Every item missing on the day is
a delay measured in lay days, and lay days are charged whether anyone is working or not.
Wooden passenger vessels
Phinisi and traditional wooden hulls carry a distinct survey emphasis: fastening condition, frames, floors and beam ends,
caulking and sheathing, deck structure, and the bilge and firefighting arrangements that matter disproportionately on a
passenger-carrying wooden vessel. Preparation normally means opening up specific areas beforehand so the surveyor forms a
judgement on evidence rather than on suspicion — because suspicion, on a wooden hull, expands the scope quickly. Detail on the
wooden hull page.
Close-out is the expensive half
Most owners think of the survey as the survey day. The cost sits in what follows: conditions of class, recommendations and
memoranda with deadlines. Each needs the repair executed and evidence assembled in a form the society will accept —
photographs, readings, material identification, welder qualification where relevant. Items closed properly do not reappear at
the next intermediate. Items closed loosely do, and they carry over onto the certificate that a buyer or a lender will read.
The five failures we see repeatedly
- Booking the dock before the surveyor. The surveyor’s diary is scarcer than the cradle.
- Tanks not gas-freed on arrival. Guarantees a partial survey and a second attendance.
- Insulation and linings still in place where readings were always going to be required.
- Machinery reassembled the day before the surveyor arrives to open it.
- Previous conditions still open. Everything after that starts from a defensive position.
Where we fit
We coordinate and prepare — access, opening-up, thickness campaign, document pack, defect close-out and the docking itself.
We do not survey and we do not issue certificates; those belong to the attending surveyor and the issuing body. The full scope
of that role is on the
survey and class coordination page, and where a survey
sits inside a larger programme it runs under
refit project management.
Talk to the repair desk
Send the vessel particulars — length overall, beam, draft, hull material, displacement, current location and the window you have available — and the Raja Ampat Shipyard Desk will come back with a written scope and a quotation in USD for intermediate or special survey preparation. Quotations name the yard, the slipway or dock, the work sequence and the assumptions behind every line.

Frequently asked questions
How early should I start planning an intermediate survey?
Three months for booking and preparation, twelve months for budgeting. The surveyor’s travel diary to eastern Indonesia is usually the binding constraint, so book attendance first and the docking window around it.
What causes most survey overruns in Sorong?
Access and documents. Tanks not gas-freed, insulation still in place where readings are required, machinery reassembled too early, or the certificate pack incomplete. Each of those turns one attendance into two.
Do outstanding conditions from the last survey matter?
Considerably. Arriving with open conditions changes the tone of the whole survey and often widens the scope. Close them out before the vessel is presented.
Is the special survey really more expensive than the others?
Yes, materially. It involves extensive opening-up, thickness measurement and structural renewal of anything deferred through the cycle. It is also entirely predictable, which is why it should be funded across the four preceding years.
