Newbuild Supervision and Owner’s Representative at Tana Beru

Tana Beru Shipyard Desk · updated 18 August 2026

Supervision at Tana Beru means physical inspection at open stages, because there is no drawing to check the vessel against. An owner’s representative attends each milestone while the work is still visible, verifies timber and workmanship against the written specification, records evidence, and signs off before the stage payment is released. Work concealed by the next stage has, in practice, been accepted.

Why supervision here is different

On a conventional newbuild, an owner’s representative checks the vessel against an approved plan set. At Tana Beru there is no plan set — the hull’s form is carried in the master shipwright’s judgement, as set out in the Konjo method. Supervision therefore shifts from document compliance to physical verification: was the specified species used, is the scantling right, is the fastening pattern correct, is the caulking sound, is the frame actually there.

The timing constraint is absolute. Frames are fitted inside a closed shell; a sole laid over them hides them. Caulking disappears under fairing and paint. Every stage conceals the one before it, so inspection has to be contemporaneous. An inspection at handover finds cosmetics, not structure.

What is inspected, and when

The evidence that makes a sign-off worth anything

A milestone report that says “framing complete, satisfactory” protects nobody. What protects an owner is a dated photographic record with a scale in frame, measurements recorded against the specification line they relate to, defects listed with an agreed remedy and re-inspection date, and a signature from both the representative and the yard. That file becomes the vessel’s build history, and it is the document that matters at survey, at registration and at resale.

Those milestones map directly onto the payment structure described in stage payments — inspection first, release second — and onto the programme in the build timeline.

Scope of an owner’s representative

• Pre-contract. Reviewing the written specification for gaps before it is signed, which is where most later disputes are actually created — see commissioning a build.
• Timber acceptance. Attending deliveries, rejecting stock outside specification, retaining legality documentation.
• Milestone inspection. Attendance, measurement, photography, defect listing, sign-off.
• Progress reporting. Regular written reports to an owner who is not in Sulawesi, with the honest schedule position rather than a reassuring one.
• Pre-launch and pre-delivery survey. Independent survey before acceptance, including anything that will be inaccessible once afloat.
• Documentation handover. Build record, timber documents, equipment certificates and manuals assembled for registration — see registration and classification.

Independence matters

Supervision has value in proportion to its independence from the party being supervised. An owner’s representative who reports to the owner, is paid by the owner, and holds rejection authority under the contract is doing a different job from a yard employee showing a visitor around. Where supervision is engaged as a separate scope, it is contracted and priced separately from construction, with fees stated in USD.

Existing vessels

The same discipline applies to a vessel already afloat. Condition survey before purchase, and supervision of a refit while the planking is open, follow the same principle: inspect while it is visible. This is build supervision at Tana Beru, not a repair or refit yard service: for haul-out and refit work, owners are referred to the ecosystem’s dedicated repair channels. The maintenance cycle that determines a hull’s working life is covered on hull life.

Supervision, survey and construction contracts in this service class are issued by PT Komodo Galangan Nusantara. To discuss scope, see the contact page.
