A World‑First Engineering & Cost Analysis Software for Silent Line Group

By Bilişim Atölyesi

Silent Line Group is a global leader in the maritime and engineering sectors, specializing in noise and vibration control solutions for yachts and commercial vessels. Known for its expertise in acoustic comfort, vibration isolation, fire protection, and thermal insulation, Silent Line has been at the forefront of integrating engineering principles into every stage of vessel construction — from early design to final fit‑out.

To support this highly technical mission, Bilişim Atölyesi partnered with Silent Line Group to design and build a bespoke software platform for cost and technical analysis of noise, vibration, and insulation systems — a tool that simply did not exist anywhere else in the world.

This platform also makes it possible to perform the high‑level engineering calculations required to build the world’s quietest yachts, transforming Silent Line’s unique expertise into a digital, scalable system.

The Challenge: Managing Complex Maritime Engineering Variables

Noise and vibration control in luxury yachts and commercial ships involves thousands of variables: hull geometry, machinery layouts, material properties, fire ratings, and installation techniques. Until now, most of these calculations and costings were done manually in spreadsheets or fragmented tools, which:

• Slowed down bid preparation and project planning
• Created risks of human error in weight, thickness, and compliance calculations
• Made it difficult to compare different engineering scenarios

Silent Line needed a single, integrated platform to perform:

• Dynamic material and cost calculations across entire vessels
• Technical compliance checks for noise, vibration, fire and thermal standards
• Real‑time scenario modelling for different configurations, suppliers, and vessel types
• High‑precision engineering computations to support the creation of the world’s quietest yachts

Expertise Provided by Sjaak van Cappellen

At the heart of this system lies the engineering knowledge of Sjaak van Cappellen, Silent Line’s founder and one of the world’s most respected authorities on noise and vibration control in the maritime sector.

Sjaak’s decades of research and hands‑on experience in acoustic insulation, vibration isolation systems, fire‑resistant and thermal materials informed the very logic of the software. His input went far beyond simply supplying data:

• He defined the acoustic target levels for different spaces onboard yachts (cabins, engine rooms, lounges, etc.)
• Mapped material properties and performance curves into a digital knowledge base
• Codified installation rules, overlap factors, and layering standards used in Silent Line projects worldwide
• Provided the compliance frameworks for international maritime standards (SOLAS, ISO noise limits, IMO fire protection requirements)
• Ensured that cost calculations and engineering outputs align with real‑world shipyard processes
• Guided the development of modules that enable the high‑level engineering calculations necessary for achieving the lowest possible onboard noise and vibration levels

This collaboration turned the software from a digital calculator into a living engineering system: every recommendation, every number reflects Silent Line’s unique know‑how distilled over years of yacht and commercial vessel projects.

The Solution: A First‑of‑Its‑Kind Maritime Engineering Platform

Working with Sjaak van Cappellen’s technical guidance, Bilişim Atölyesi engineered a modular platform that allows Silent Line to:

1. Model Material Requirements Dynamically

• Input vessel data, compartment layouts, or 3D references
• Automatically calculate required quantities, weights, and classes for:
  • Acoustic insulation panels
  • Anti‑vibration floorings
  • Fire‑protection layers
  • Thermal barrier components
• Handle multi‑layer builds, installation directions, overlaps, and fixing zones

2. Calculate Multi‑Level Costs in Real Time

• Compare material, labor, and logistics costs by zone, layer, or supplier
• Generate real‑time project budgets under different scenarios
• Produce accurate quotations for shipyards and yacht builders

3. Check Compliance Automatically

• Validate that proposed solutions meet target noise and vibration levels
• Ensure compliance with international fire and thermal standards
• Simulate material performance under vibration and shock loads

4. Perform High‑Precision Engineering Calculations

• Enable Silent Line engineers to model the acoustic and vibration performance of entire vessels
• Support “what‑if” scenarios to achieve ultra‑low noise thresholds
• Provide the computational backbone for designing the world’s quietest yachts

5. Generate Exportable Engineering Reports

• Create detailed PDF reports for technical and financial data
• Map Bill of Materials (BOM) by compartment or system
• Store configurations for future vessel classes or retrofits

Impact: Setting a New Industry Benchmark

With this platform, Silent Line Group has achieved:

• 90% faster estimation and proposal preparation
• Error‑free cost forecasting and technical compliance
• The ability to digitize and scale Sjaak van Cappellen’s engineering know‑how
• A stronger competitive edge with a proprietary, world‑first engineering tool
• The capacity to run the advanced calculations required to produce the quietest yachts in the world

This is more than a software tool — it is a strategic asset that transforms Silent Line’s intellectual capital into a scalable, data‑driven process.
