Common Questions

Frequently
Asked

What is IMO-certified marine interior design?

IMO-certified marine interior design means all materials, finishes, and structural elements meet the International Maritime Organisation's safety standards, including fire resistance, smoke toxicity, and structural load requirements. As an IMO-certified materials supplier, every surface, fabric, laminate, and fitting we specify has been tested and approved to these international maritime safety regulations.

How long does a cruise ship interior refurbishment take?

A full cruise ship interior refurbishment typically takes 2 to 6 months depending on scope, vessel size, and shipyard availability. We manage the entire timeline, from concept and AutoCAD documentation through fabrication, shipyard coordination, and final installation, minimising the vessel's time out of service.

Where does Irregular Lines Maritime operate?

We are headquartered in Singapore and serve clients across Asia-Pacific and the Mediterranean. Our fabrication network spans Singapore, Indonesia, China, Malaysia, and Greece, giving clients access to competitive, IMO-compliant supply chains across two continents.

What types of vessels do you design for?

We specialise in cruise ships and passenger vessels, including expedition vessels, river cruise ships, and offshore platforms. We handle full interior refurbishments, IMO-certified material supply, and bespoke marine carpentry for any passenger-carrying vessel.

What is sustainable marine interior design?

Sustainable marine interior design means selecting materials that minimise environmental impact over the full vessel lifecycle: low-emission finishes, responsibly sourced timber, recycled-content fabrics, and long-life surface treatments that reduce replacement frequency. All materials still meet IMO safety standards. We integrate sustainable sourcing as a core part of every project specification.
