Essential Marine Hydraulic Systems Every Ship Should Have

In the marine world, power, control, and safety go hand in hand. Whether it’s a cargo ship, fishing vessel, offshore rig or navy ship, marine hydraulic systems play a huge role in keeping everything running smoothly.

From steering to anchoring, lifting to stabilising – hydraulics are everywhere onboard. And choosing reliable Marine Hydraulic Systems Suppliers becomes critical for Indian ship owners who operate in tough sea conditions.

At Hindustan Marine, we help shipowners, engineers and fleet managers across India select and install high‑quality hydraulic systems that last long and perform even better. Let’s break this down in a simple way.

Why Marine Hydraulic Systems Are Essential on Ships

Marine hydraulic systems use pressurised fluid to create powerful movement. They are preferred over electric or mechanical systems because they:

• Deliver high power in compact space
• Work smoothly in harsh marine conditions
• Offer better control and safety
• Handle heavy loads easily

As per industry data, over 70% of ship machinery worldwide depends on marine hydraulic systems, especially in cargo and offshore vessels.

In India, with over 7,500 km of coastline and booming port activity, demand for reliable marine hydraulic system automation is increasing rapidly.

What Makes a Hydraulic System ‘Marine Grade’?

Not all hydraulic systems are suitable for ships. Marine-grade systems are specially designed to survive:

• Saltwater corrosion
• High humidity
• Strong vibrations
• Temperature changes

A true marine-grade system also:

• Uses corrosion‑resistant materials
• Has IP65–IP68 rated components
• Complies with DNV, ABS, CE, and BIS standards

At Hindustan Marine, we only supply systems tested for Indian coastal and offshore conditions.

Core Marine Hydraulic Systems Every Ship Should Have

Let’s look at the most essential hydraulic systems that every vessel should be equipped with.

✅ Steering Gear System

This system controls the ship’s rudder and direction.

Where it’s used:

• Cargo ships
• Passenger vessels
• Naval ships

Why it matters:

• Safe navigation in ports and narrow channels
• Emergency steering backup

Ships equipped with hydraulic steering systems show 40% better manoeuvring control in congested Indian ports.

✅ Anchor and Mooring System

These systems use hydraulic windlasses and capstans to drop and retrieve anchors.

Applications:

• Anchoring in deep waters
• Berthing and mooring at ports

Hydraulic anchor systems reduce manual effort and increase safety, especially during rough weather.

✅ Cargo Handling System

This includes hydraulic cranes, winches, and lifts.

Used for:

• Lifting containers
• Opening hatch covers
• Handling heavy cargo

A well-designed hydraulic cargo system improves loading/unloading speed by 25–30%, reducing port turnaround time.

✅ Stabiliser and Trim Systems

These systems help reduce rolling and pitching of ships.

Common in:

• Passenger ships
• Cruise liners
• Naval vessels

Hydraulic stabilisers improve onboard comfort and safety by minimising vessel movement by up to 60% in rough seas.

✅ Propulsion Control System

These systems manage:

• Thrusters
• Controllable pitch propellers
• Direction control

Used heavily in:

• Tugboats
• Offshore vessels
• Harbour support ships

Smooth hydraulic propulsion helps reduce fuel wastage and enhances control.

✅ Hatch Cover and Ramp Control Systems

These are hydraulic cylinder-based systems used to:

• Open and close hatch covers
• Operate loading ramps in Ro‑Ro vessels

They ensure cargo safety and weather protection.

✅ Hydraulic Power Unit (HPU)

HPU is the heart of any hydraulic system.

It includes:

• Pumps
• Reservoir
• Filters
• Cooling system

HPUs supply stable pressure to all hydraulic systems on board.

✅ Lifeboat Launch and Recovery Systems

These systems are used during emergencies.

They control:

• Davits
• Winches
• Lifeboat lowering

SOLAS regulations make these systems mandatory for passenger and naval vessels.

✅ Deck Machinery Systems

These include:

• Towing winches
• Rope tensioners
• Capstans

Very common in:

• Fishing trawlers
• Tugboats
• Coastal cargo vessels

Advanced Hydraulic Systems for Modern Ships

Modern vessels now use advanced marine hydraulic system automation, including:

• ROV (Remotely Operated Vehicle) deployment systems
• Hydraulic jacking systems for offshore rigs
• Automated gangways and boarding platforms

These systems improve efficiency and reduce manual workload.

Factors to Consider When Choosing Hydraulic Systems

Before choosing any system, check:

• Load capacity
• Pressure rating
• Spare part availability in India
• Compatibility with automation systems
• Warranty and AMC options

Choosing local and reliable Marine Hydraulic Systems Suppliers ensures faster support and better service.

Role of Marine Hydraulic Systems in Indian Defence and Offshore Sectors

Marine hydraulic is critical in:

• Indian Navy submarines and warships
• Coast Guard patrol vessels
• ONGC offshore rigs and platforms

India’s offshore fleet relies heavily on Marine Hydraulic systems for drilling, lifting, and safety operations.
