New Vessel Construction Phases: From Order to Delivery

A decision to build a new yacht or ship is not one payment + one delivery. The process unfolds in milestones — from pre-agreement through to the post-delivery warranty period. This guide walks through the typical phases of a newbuild project, what gets signed at each step, and how financing is coordinated.

The seven typical phases

A newbuild project typically progresses in this order:

1. Pre-agreement + yard selection

Owner needs (vessel type, length, intended use)
Technical + commercial proposals from candidate yards
Yard references, history, and financial standing reviewed
Draft technical specification prepared

Output: chosen yard + pre-agreement (LOI or MOA)

2. Spec + design finalisation

General arrangement (GA) drawings
Specification document detailed for all systems
Class society + flag choice decided
Architecture + interior design decisions

Output: finalised spec + GA drawings

3. Shipbuilding contract signature

Built on a standard template (SAJ, NSF Newbuilcon, BIMCO)
Price + milestone payments + delivery date set
Refund guarantee structure agreed
Penalty / performance guarantee clauses inserted

Output: signed contract + first milestone payment begins

4. Construction start (steel cutting)

Steel cutting ceremony (symbolic start)
Plate preparation, block production begins
Owner appoints an owner's representative (OR) at the yard
The OR oversees progress, reports, and decides on the owner's behalf

Output: second milestone paid (typically steel cutting + a percentage)

5. Blocks + main systems

Blocks completed
Main engine delivered
Systems (generator, navigation, HVAC) installed
Interior fit-out begins (on the yacht side)
Class society surveys progress

Output: intermediate milestone payments (tied to keel laying, launching milestones)

6. Sea trial + delivery preparation

Sea trial — performance + systems testing
Class society's final pre-delivery survey
Spec compliance verified
Outstanding items (punch list) listed + resolved

Output: successful sea trial + delivery approval

7. Delivery + warranty

Delivery protocol signed
Registration under the owner's flag
Final milestone paid
Insurance policy activated
Warranty period begins (typically 12–24 months)

Output: owner takes delivery; yard remains responsible during warranty

Milestone payment structure

A typical milestone payment structure (example — actuals vary):

| Milestone | Trigger | Approx % | |---|---|---| | 1 | Contract signature | 10–20% | | 2 | Steel cutting | 10–20% | | 3 | Keel laying | 10–20% | | 4 | Launching | 10–20% | | 5 | Sea trial / delivery | 20–40% |

These figures are indicative — real projects vary by yard strength and negotiation. Yachts typically use 5–6 milestones; commercial ships 4–5.

Refund guarantee — a critical protection

The owner carries risk on every milestone paid: if the yard goes bankrupt or fails to deliver, that money is lost. To manage this risk, a refund guarantee is used:

When the owner pays a milestone, the yard's bank issues a refund guarantee to the owner
If the yard fails to deliver, the bank refunds the paid milestone
Standard for European or Chinese yards
Possible for Turkish yards too, but structured project-by-project

For depth: Refund guarantee

Coordination with financing

Newbuild financing is typically structured as milestone drawdown:

Owner pays the first milestone from own funds (or bridge financing)
Subsequent milestones are funded via loan drawdowns
Bank requests progress reports from the yard before each drawdown
Refund guarantee is also assigned to the bank (collateral)
At delivery, final drawdown + mortgage perfection + full financing structure put in place

Owner's representative — why it's needed

The owner can't continuously inspect a distant yard. The owner's representative (OR) sits at the yard and watches:

Spec compliance
Quality oversight
Delay warnings
Owner-side approval process

Typically an experienced naval engineer or independent surveyor. Full-time on superyacht projects; visit-based on smaller projects.

Common pitfalls

Contract without sufficient technical spec → later changes (variation orders) get expensive
Milestone paid without refund guarantee → yard risk sits with the owner
Building without an OR → defects surface at the last minute
Tight delivery date → sea trial / punch list phases get compressed
Class society + flag uncoordinated → pre-delivery surprises

FAQ

How long does a newbuild project take?

Depends on length + type + yard backlog. Typical range: 12–36 months. On the yacht side, mid-size (30–40m) often takes 18–24 months; superyachts (50m+) typically 24–36 months.

Is the yard price fixed?

Most contracts use a fixed price. But variation orders (spec changes) bill on top. This is why finalising the spec before contract signature is critical.

When is an owner's representative needed?

From steel cutting through to post-delivery. On professional projects the OR is appointed at contract signature.

How does newbuild financing differ from purchase financing?

Two key differences: (1) milestone drawdown — the loan is not disbursed in one shot, it's tied to milestones; (2) the refund guarantee chain — collateral structure is more complex. Tenor, typical pricing and structure also differ.

What does the owner do during construction?

Very active at the start (spec + design decisions), low-activity in the middle (the OR runs progress), active again near delivery (sea trial + punch list + logistics).
