BKI Class, Kemenhub Approval and New-Vessel Documents

BKI class is generally required in Lombok for commercial vessels over 35 GT, steel or aluminium hulls, higher passenger capacities and for financiers or insurers who specify classed tonnage. All Kemenhub passenger vessels in NTB must meet separate safety, stability and manning rules overseen by the local Syahbandar, with a defined sequence of surveys and documents from Surat Ukur through to Pas Besar or Pas Kecil and safety certificates.

When BKI Class Is Required For A New Boat In Lombok

In Indonesia, Biro Klasifikasi Indonesia (BKI) sets classification rules for hull structure, machinery, electrical systems and safety equipment. Not every commercial boat built in Lombok needs full BKI class, but some clearly do.

BKI class is typically requested or required when:

• The vessel is above about 35–50 GT and will trade commercially between ports.
• The hull is steel or aluminium, or a composite hull that a bank or insurer wants classed.
• International or inter-provincial service is planned, with more scrutiny from Kemenhub.
• Project finance or leasing requires a classed asset as collateral.
• The owner needs structured maintenance and periodic surveys aligned with class rules.

Smaller wooden tour boats, dayboats and workboats in NTB often operate under Kemenhub and Syahbandar oversight without full BKI class, relying instead on local survey and safety certificates. The decision comes down to tonnage, route, construction material, and stakeholder requirements.

Kemenhub Passenger Vessel Approval In NTB

Separately from class, Kementerian Perhubungan (Kemenhub) regulates passenger vessels through directorate rules, circulars and technical guidelines. In West Nusa Tenggara (NTB), these are implemented via the local Syahbandar offices (harbour masters) in ports such as Lembar, Labuan Bajo, Bangsal and Teluk Nara.

For a new passenger boat built in Lombok, Kemenhub and Syahbandar will typically require:

• Approved general arrangement (GA) and structural drawings suitable for the intended passenger capacity.
• Stability calculations and, in many cases, an inclining test once the boat is launched.
• Fire-fighting, life-saving appliances and radio equipment matched to the trading area.
• Crew qualification and minimum manning that meet Kemenhub rules for the vessel type and GT.
• Operational documentation on routes, passenger limits and safety procedures.

Approval is not a single document. It is a series of surveys and endorsements culminating in a set of certificates that allow the vessel to carry passengers legally. Whether or not you pursue BKI class, these Kemenhub passenger requirements still apply to commercial boats operating around Gili Trawangan, Gili Meno, Gili Air, Senggigi, Sekotong and wider NTB routes.

Core New-Vessel Documents: From Hull To Legal Vessel

Indonesia treats a newly built hull as an object with dimensions and tonnage before it becomes a legal vessel in service. The document flow usually follows this order:

Stage	Key Document	Issued By	Main Purpose
1. Measurement	Surat Ukur	Authorized surveyor / Kemenhub unit	Official dimensions, GT/NT tonnage basis
2. Registration	Gross Akte	Ship registry office	Vessel registration and legal ownership record
3. Tonnage Pass	Pas Besar or Pas Kecil	Syahbandar	Navigation pass with name, GT, port of registry
4. Safety	Sertifikat Keselamatan	Syahbandar / Kemenhub surveyor	Compliance with passenger/safety rules
5. Operation	SIUPAL / SIOPSUS (where relevant)	Kemenhub / related ministry	Commercial sea transport or tourism operations licence

Together, these form the backbone of sertifikat kapal Lombok for a new commercial unit. Without them, a finished hull remains a private object; with them, it becomes a trading vessel recognised by the authorities.

Surat Ukur, Gross Akte And Pas Besar / Pas Kecil

The first legal step for a new hull is measurement. Surat Ukur records length, breadth, depth and tonnage. This is the basis for almost everything that follows, from GT-based fees to route limitations and manning requirements.

Once measurement is complete and the vessel has a hull identification (name and port of registry reserved where applicable), the owner can move towards registration:

• Gross Akte records ownership, tonnage and key particulars. It is the ship’s registration certificate.
• Pas Besar kapal Lombok is usually issued for larger GT vessels on longer routes.
• Pas Kecil applies to smaller vessels within defined local waters and GT thresholds.

Whether a new Lombok build ends up under Pas Kecil or Pas Besar depends on the design GT and the planned operating area. This needs to be considered at the design stage, not after launch, because superstructure and layout choices affect tonnage.

Sertifikat Keselamatan And Passenger-Specific Requirements

For a passenger vessel, the navigation pass alone is not enough. The safety regime adds further layers before commercial operation is allowed.

Passenger approvals normally involve:

• Structural and stability evaluation to ensure the boat can safely carry the intended passenger count.
• Verification of lifejackets, liferafts, buoys, emergency lighting and alarms.
• Fire detection, extinguishers and fixed systems where specified by rule.
• Machinery, fuel and electrical checks to reduce fire and flooding risks.
• Sea trials to confirm manoeuvrability, stopping distances and basic handling.

On successful completion of survey, the Syahbandar or appointed Kemenhub surveyor issues a Sertifikat Keselamatan. This certificate sets out route limitations, passenger capacity and equipment requirements. It sits alongside the Pas Besar or Pas Kecil as a core piece of boat certification Lombok for tourist and fast ferry traffic.

Commercial Operation Licences: SIUPAL And SIOPSUS

In addition to ship certificates, commercial operators may need business-operation licences. For many owners, the relevant documents are:

• SIUPAL (Surat Izin Usaha Perusahaan Angkutan Laut) for sea-transport companies operating Indonesian-flagged vessels.
• SIOPSUS or related tourism-operation licences for vessels used in tourism activities such as diving, day trips and charter.

These are not ship certificates; they are company-level licences connected to the fleet. For new passenger or charter vessels entering service around Lombok or Labuan Bajo, it is important to plan vessel documentation and company licences together so that the boat can be used as intended once construction is complete.

Who Lodges What: Builder, Owner, Notary And Surveyor Roles

New-build projects are smoother when it is clear who is responsible for each regulatory step. For a typical bki class boat Lombok project or a non-classed passenger vessel, responsibilities often divide as follows:

• Builder: provides drawings, specifications and construction records required for survey; coordinates on-site visits; implements technical changes requested by surveyors; supports measurement for Surat Ukur.
• Owner or owning company: appoints a notary and handles applications for Gross Akte, Pas Besar or Pas Kecil, and business-operation licences; pays regulatory fees and taxes.
• Surveyor (BKI and/or Kemenhub): examines the hull, structure, machinery and safety equipment; conducts sea trials and stability tests; recommends issuance of certificates.
• Notary and ship registry office: prepare ownership instruments, register the vessel and issue Gross Akte.
• Syahbandar: issues the Pas Besar or Pas Kecil and safety certificates once all technical and legal conditions have been met.

On our side, the build team focuses on the technical file, survey readiness and physical compliance, while owners or their appointed agents manage the legal and business paperwork. This division is normally formalised at contract stage, alongside commercial terms described in the contract, payment and supervision framework.

Suggested Timeline From Design To Certificates

Regulatory work needs to be integrated with the physical build. A typical indicative sequence for a new commercial or passenger vessel from Lombok is:

1. Concept design and route planning, including tonnage and passenger-capacity targets.
2. Naval architecture and structural design, optionally using rules suitable for BKI class.
3. Submission of drawings to BKI and/or Kemenhub technical units where required.
4. Keel laying and hull construction with periodic survey visits.
5. Pre-launch measurement scheduling to prepare for Surat Ukur.
6. Launch, inclining test and sea trials, often coordinated with surveyors.
7. Issuance of Surat Ukur, then registration and Gross Akte.
8. Safety surveys, equipment checks and finalisation of Sertifikat Keselamatan.
9. Issuance of Pas Besar or Pas Kecil and activation of SIUPAL/SIOPSUS as applicable.

Detailed durations depend heavily on vessel size, specification and surveyor availability. When we outline a build window, we factor in regulatory steps within the broader build process and timeline, including monsoon-season launch constraints in Bangsal, Teluk Nara or Lembar.

For fast passenger ferries, there are additional constraints on powering, structural loading and sea-keeping. These are addressed during design and in the fast boat build planning phase to align with both class rules (if applied) and Kemenhub passenger regulations.

Frequently Asked Questions

What documents does a new Lombok-built boat need?

In sequence: measurement producing the Surat Ukur, registration — Pas Kecil for vessels under 7 GT or Pas Besar above — then the safety certificate and crew licences, each issued through the harbourmaster (Syahbandar) and transport-ministry offices. Commercial passenger service adds its own approvals before guests board.

When is BKI class mandatory?

Class applies by service and size thresholds — qualifying passenger vessels and larger commercial tonnage — while small private craft follow the registration route only. Whether a project needs class is settled at the brief stage because class changes the build itself: surveys during construction, approved drawings and material certificates, not paperwork bolted on later.

How long does the paperwork take?

Honest processing ranges run from weeks for measurement and small-craft registration to considerably longer where class and passenger approvals are involved. The desk starts the file during construction and has each stage verified as part of build supervision — see the inspection programme — so launch day is never paperwork-blocked.

Are the government fees expensive?

No — statutory fees are modest and stated factually in IDR in every quotation. The expensive failure is sequencing: a finished boat stranded ashore because measurement was never booked, or a passenger service delayed a season because class involvement started after the hull was planked. Sequence discipline, not fee size, is what this page protects.
