Process

Five auditable stages, governed by ISO 9001:2015

01

Briefing and assessment

We discuss the vessel's intended use, operating route, passenger or cargo requirements and budget in order to define a clear project scope.

02

Design and quotation

We prepare preliminary drawings, 3D renderings and an itemised quotation, together with a construction schedule.

03

Construction

Our in-house teams erect the steel structure, carry out welding and assembly, sandblast and paint the hull, and install the engines and onboard systems.

04

Trials and acceptance

We conduct operational trials and inspect all systems and safety equipment prior to delivery.

05

Delivery and after-sales support

We arrange vessel registration and licensing with the Marine Department, hand over the vessel, and continue to support you with steel ship repair services and spare parts.
