A leading global Yacht equipment OEM partnered with ALTEN to tackle the integrating complex systems into confined spaces, ensuring flawless performance throughout a yacht’s lifespan and critical challenge of reducing unit manufacturing costs without compromising on safety, performance, and quality standards. ALTEN stepped in with a structured, design-led, and cross-functional approach delivering not just cost savings, but faster execution cycles and stronger collaboration across engineering.

Project Summary & Overview:

The Beach Club Platform project involved developing a hydraulic Actuators folding platform system that transforms the stern area of the yacht into a luxurious beach club zone, providing direct access to the sea.

The project required a custom-engineered, lightweight, and corrosion-resistant platform capable of withstanding marine conditions while ensuring smooth hydraulic operation, minimal noise, and seamless integration with the yacht’s hull structure and aesthetic.

• Retract flush into the yacht, remaining invisible when not in use.
• Operate quietly and smoothly, with proportional control.
• Integrate safety rails, lighting, and anti-slip surfaces.
• Be service-friendly and compatible with the yacht’s hydraulic power unit (HPU).
• Meet Lloyd’s Register safety and structural requirements

The Scope of Work:

Concept & Design Engineering:

• 3D modeling of the beach platform.
• Interface design with yacht hull and adjacent structures.

Structural Analysis:

• Load calculations (static, dynamic, and sea-load conditions).
• Verification of hinge points, hydraulic cylinders, and locking mechanisms.

Hydraulic System Integration:

• Selection and layout of hydraulic cylinders and control units.

Material & Component Specification:

• Use of marine-grade aluminum/stainless steel.
• Surface treatment for corrosion resistance.

Manufacturing & Assembly Support:

• Preparation of production drawings and installation guidelines.

Key Sections (Use Bullet Points)

Challenge:

• Complex Geometry & Limited Space: The stern curvature and compact integration zone required precise hinge alignment and compact hydraulic arrangement.
• Load and Stability: Platform needed to withstand wave impacts and personnel load without excessive deflection or vibration.
• Corrosion and Weight Optimization: Achieving lightweight structure without compromising strength and marine durability.
• Tight Tolerances: Ensuring exact matching of platform to hull when closed to maintain watertight integrity and yacht aesthetics.
• System Synchronization: Hydraulic cylinders needed synchronized motion for smooth folding and unfolding operation.
