Hiring an independent marine surveyor in Lombok before you accept a new boat protects your final payment, your future operating costs and your compliance with Indonesian flag rules. A good surveyor will methodically check structure, systems, stability and documentation, then issue a defect list (snagging list) that the yard must address before you sign off and the vessel leaves the slipway.
Why an owner’s surveyor pays for itself
A new-build handover is when your financial risk is highest: most staged payments are made, but long-term defects are not yet visible. An independent marine surveyor in Lombok focuses only on your interests, not on keeping build schedules or margins. The fee is modest compared to latent defects in hull, machinery, fire safety or passenger arrangements that can cost many times more to rectify later.
Common areas where a surveyor can save you money include underspecified equipment, misaligned shafts, non-compliant passenger layouts, marginal electrical installations, and drainage or bilge arrangements that look acceptable at the dock but fail at sea. Identifying these at handover stage means they are corrected at the yard’s cost, not after you start operating.
What a pre-delivery survey in Lombok typically covers
The exact scope depends on vessel type (wooden phinisi, GRP fast boat, steel workboat, liveaboard, private yacht), but a competent marine surveyor in Lombok will usually combine structural, systems, safety and documentation checks.
Structural and hull inspection
- Keel, frames, floors and stringers for alignment, fastening and visible defects.
- Planking or plating thickness versus drawings or classification requirements.
- Transom, deck beams, bulwarks and railings for stiffness and proper fastening.
- Underwater fittings: seacocks, skin fittings, shaft logs and rudder ports.
Machinery and systems
- Main engines, gearboxes, shafting and propellers: alignment, mountings, exhaust routing.
- Fuel systems: tank construction, venting, filtration, accessibility and shut-off valves.
- Fresh water, grey and black water systems: materials, hose runs, venting, pump access.
- Electrical: main distribution boards, breaker sizing, cable routing, earthing and labelling.
Safety and passenger arrangements
- Lifejackets, liferafts, throwables and fire extinguishers count and distribution.
- Escape routes, signage, emergency lighting and muster points.
- Rail heights, stair treads, handrails, non-slip surfaces in critical areas.
- Guarding of rotating machinery and hot surfaces.
Documentation and regulatory basis
- Checking plans and calculations used for BKI or Kemenhub submissions.
- Verifying that the build matches approved general arrangement and safety plans.
- Confirming that serial numbers of engines and major equipment match invoices.
- Reviewing draft Surat Ukur and Gross Akte data for obvious inconsistencies.
How to scope your surveyor’s brief
You should give your surveyor a written scope that fits your contract structure, build method and intended trade. This avoids assumptions and clarifies what will be looked at before you reach the final milestone in your contract and payment supervision framework.
Key decisions on scope
- Level of access: Will the surveyor attend only at pre-delivery, or also during construction (keel, framing, mechanical installation, pre-closing of linings)?
- Test witnessing: Will the surveyor witness sea trials, load tests, bilge and fire pump tests, blackout simulation and emergency steering?
- Regulatory checks: Is the vessel intended for Kemenhub domestic passenger service, tourism-only operations, or private use?
- Owner preferences: Acoustic comfort, interior fit, finish quality, and vibration tolerance can be written into the brief.
Deliverables you should request
- A written survey report with photos, organised by system and compartment.
- A clear defect / snagging list with severity ranking and suggested remedies.
- Confirmation of any items that must be corrected before passenger approval.
- Suggested items for your planned maintenance schedule and spare parts list.
Timing surveyor visits in the build process
Having a marine surveyor only at final handover is better than nothing, but early-stage checks often prevent expensive rework. On more complex projects, owners often combine several visits aligned with the build phases described in our build process timeline overview.
| Stage | Build phase | Typical surveyor focus |
|---|---|---|
| 1 | Keel, frames, primary structure | Keel straightness, frame spacing, fastening, material selection, corrosion protection. |
| 2 | Hull closed, tanks and bulkheads in | Tank construction, watertight bulkheads, penetrations, limber holes, bilge layout. |
| 3 | Machinery and systems installation | Engine beds, shaft alignment (preliminary), piping runs, cable management, ventilation. |
| 4 | Outfitting and interior | Escape routes, stair geometry, handrails, joinery clearances, access panels to systems. |
| 5 | Pre-launch and pre-delivery | Full inspection, system testing, documentation review, snagging list preparation. |
Indicative cost bands for an independent surveyor
Fees vary by vessel size, complexity and how many yard visits you request. In Lombok and the surrounding region, owners typically budget surveyor costs as a planning percentage of the overall project value rather than a fixed fee per day.
| Vessel size | Example vessel type | Indicative surveyor budget (USD) | Notes |
|---|---|---|---|
| Up to 15 m | Private yacht, small fast boat | 3,000 – 6,000 | Usually one to two visits plus sea trial witnessing. |
| 15 – 30 m | Day boat, small liveaboard, workboat | 6,000 – 12,000 | Multiple build-stage visits, full documentation review. |
| 30 – 45 m | Liveaboard, phinisi, passenger vessel | 12,000 – 25,000 | Extended attendance and detailed stability / systems checks. |
These figures are indicative planning ranges only. The actual fee will depend on the surveyor’s day rate, travel, and the technical depth you request.
From survey findings to a formal snagging list
The main product of your pre-delivery survey is a structured defect list. This becomes part of the handover process and links directly to your final payment and acceptance documentation. It is important that defects and observations are written in clear, technical language that the shipyard can action.
Typical snagging list structure
- Location: compartment, frame station or deck level.
- System: hull, machinery, electrical, plumbing, safety, interior, paint.
- Description: objective statement of what is wrong or incomplete.
- Severity: critical (safety/operability), major (functionality), minor (cosmetic).
- Recommended action: repair, replacement, adjustment, additional testing.
Managing snagging before final payment
Owners usually link release of the final instalment to written closure of all critical and major items, with minor cosmetic items scheduled for completion before a defined date or prior to commercial operation. Clear communication between owner, surveyor and yard prevents these lists turning into disputes and keeps the focus on practical solutions.
How the survey ties into sea trials and handover
No survey is complete without observing the vessel underway. Your surveyor should attend sea trials and run through a structured test matrix. Owners often combine this with their own sea trial checklist before final payment so that both operational and technical perspectives are covered.
- Speed and fuel consumption at different RPM bands.
- Steering response, turning circle and behaviour in reverse.
- Noise and vibration in key cabins and passenger spaces.
- Bilge pump, fire pump and emergency steering operation under load.
- Generator loading, electrical system stability and battery charging.
The surveyor’s observations during sea trial often add further items to the snagging list: vibration requiring propeller balancing, shaft whine, overheating exhaust components, or inadequate drainage at particular trims. It is easier to correct these while the vessel is still in the builder’s control.
Selecting a marine surveyor in Lombok or nearby
When appointing a marine surveyor in Lombok, Bali or elsewhere in Indonesia, focus on experience with your hull material and intended trade rather than labels. A surveyor familiar with wooden phinisi construction may not be the best choice for a high-speed GRP catamaran, and vice versa.
- Ask for example reports (with client details removed) to see clarity and technical depth.
- Check whether they understand BKI and Kemenhub practices for your vessel type.
- Confirm they are comfortable working through an interpreter if required with yard teams.
- Agree in writing on report format, delivery time and what happens if sea trials are delayed.
For owners based overseas, it is often practical to combine the surveyor’s visit with your own handover trip, so decisions on any major findings can be made on site with everyone present.
Frequently asked questions
Do I really need an independent surveyor for a brand new boat?
A new vessel still benefits from an independent survey because construction tolerances, system integration and regulatory details are complex. Even competent yards can miss issues that only appear under systematic inspection or during sea trials. A surveyor gives you a structured view of risks before you release final payment or start carrying passengers.
Should my surveyor in Lombok be BKI or Kemenhub approved?
For an owner’s survey, formal approval is less important than practical experience with similar vessels and Indonesian flag requirements. BKI and Kemenhub will conduct their own inspections for statutory certificates. Your surveyor’s role is to protect your commercial and technical interests, not to replace or represent the regulators.
Who pays for fixes identified in the snagging list?
Defects that show the vessel does not meet the signed specification, drawings or class and flag requirements are normally the yard’s responsibility. Owner-requested changes or upgrades beyond the contract are usually for the owner’s account. This division should be clarified in the build contract so that survey findings can be allocated fairly.
Can the yard refuse access to my surveyor?
Access terms should be written into the build contract from the start. Most yards accept independent surveyors provided visits are coordinated and safety rules are followed. If a contract is already signed without this clause, you will need to negotiate practical access that does not disrupt critical production stages or sensitive subcontractor work.
When is the best moment to schedule the pre-delivery survey?
The pre-delivery survey works best when all major systems are installed and operational, but before the vessel is painted and fully furnished. At this point, structural and system details remain accessible, but the boat is close enough to completion that findings can be fixed without reopening finished spaces or rescheduling regulatory inspections.
