The True Cost of a Gangway

Why Purchase Price Is Only the Beginning

When marine equipment is being specified, purchase price is naturally one of the first numbers considered.

But for equipment expected to operate for years — often in demanding marine environments — initial purchase price can represent only a fraction of the eventual cost.

For gangways and accommodation ladders, the real financial equation includes installation, integration, inspection, maintenance, spare parts, repairs, downtime, upgrades and eventual refurbishment or replacement.

The better question is therefore:

“What will this system cost to own and operate?”

The Five Cost Stages

A useful way to evaluate a marine access system is to consider five stages.

1. Acquisition

This includes:

• equipment purchase
• engineering
• fabrication
• controls
• accessories
• certification
• freight

A lower initial price can appear attractive at this stage.

But it does not necessarily indicate lower lifecycle cost.

2. Installation and Integration

Installation may require:

• structural modifications
• electrical connections
• hydraulic connections
• control integration
• commissioning
• testing
• class or inspection activities

A system requiring significant vessel modification may carry substantially greater installed cost than its purchase price suggests.

3. Operation

The system then begins accumulating operational cost.

Consider:

• operator requirements
• deployment time
• energy consumption
• manual handling
• routine inspections
• consumables
• wear components

A system that is difficult to operate or requires extensive manual intervention can create operational costs that never appear on the original quotation.

4. Maintenance

Marine equipment operates in an aggressive environment.

Saltwater, corrosion, mechanical wear, hydraulic contamination, repeated loading and exposure to weather can all affect equipment condition.

Maintenance therefore needs to be considered during design.

Questions include:

• Are service points accessible?
• Are wear components replaceable?
• Are hydraulic components standardised?
• Is documentation available?
• Are replacement parts obtainable?
• Can faults be diagnosed efficiently?

5. Downtime and Failure

This can be the most expensive category.

A failed access system may affect:

• crew movements
• passenger transfers
• port operations
• maintenance activities
• vessel schedules
• offshore operations

The financial consequence is not necessarily the repair itself.

It can be the operational disruption created by the failure.

Reliability Has a Commercial Value

Reliability is often discussed as a technical characteristic.

It should also be viewed as an economic one.

If a system operates reliably and maintenance can be planned, operators gain predictability.

Predictability allows:

• planned maintenance
• controlled spares
• scheduled inspections
• reduced emergency call-outs
• better vessel planning

EHL’s marine service capability is structured around design, installation, inspection, maintenance, repair and lifecycle support rather than treating the equipment as a one-time supply item.

Design for Maintenance

A good access system should be designed with maintenance in mind from the beginning.

That means considering:

Access

Can technicians safely reach components?

Isolation

Can hydraulic or electrical systems be isolated?

Diagnostics

Can faults be identified without excessive dismantling?

Replacement

Can wear components be replaced efficiently?

Documentation

Are drawings, manuals and service information available?

Inspection

Can structural and functional condition be assessed?

These questions may have little impact on the appearance of a gangway.

They can have a major impact on its lifetime cost.

---

The Hidden Cost of Obsolescence

Modern access systems can contain:

• PLCs
• sensors
• hydraulic valves
• electrical controls
• HMIs
• remote controls
• specialised components

Technology changes.

A system that relies heavily on obsolete or proprietary components can become increasingly difficult to support as it ages.

Lifecycle engineering should therefore consider component availability and future maintainability.

---

Retrofit Can Be More Economical Than Replacement

An ageing gangway does not automatically need to be replaced.

Depending on condition, it may be possible to:

• upgrade controls
• replace hydraulic components
• improve safety systems
• refurbish structural components
• replace worn bearings
• modernise instrumentation
• improve handrails or surfaces

EHL’s engineering capability includes retrofit, upgrade, repair and lifecycle support, allowing existing systems to be assessed rather than automatically replaced.

---

A Better Procurement Question

Instead of asking:

“Who has the lowest purchase price?”

ask:

“Which system provides the strongest value across its expected operating life?”

That changes procurement from a simple capital expenditure comparison into a lifecycle assessment.

---

Conclusion

A marine gangway is not consumed when the purchase order is signed.

It begins its economic life.

The true cost is determined by how effectively the system can be installed, operated, maintained, repaired, upgraded and supported.

For vessel owners and operators, lifecycle value should therefore be considered alongside purchase price from the very beginning.

FAQ

What is the total cost of ownership of a marine gangway?

The total cost of ownership includes considerably more than the purchase price. It can include engineering, installation, vessel integration, commissioning, inspections, preventative maintenance, spare parts, repairs, downtime, upgrades and eventual refurbishment or replacement.

Why is the cheapest marine gangway not always the lowest-cost option?

A lower purchase price can be offset by higher installation costs, greater maintenance requirements, difficult access to components, expensive spare parts, downtime or limited lifecycle support. Comparing total lifecycle cost provides a more meaningful assessment of long-term value.

How can marine gangway design reduce lifecycle maintenance costs?

Maintenance costs can potentially be reduced through accessible service points, appropriate component selection, robust materials, maintainable hydraulic and electrical systems, clear documentation, condition monitoring and a preventative maintenance strategy established during design.

How often should a marine gangway be inspected?

Inspection frequency depends on the equipment, vessel, applicable requirements, operating environment and asset-management regime. Inspection should be based on the relevant standards and the manufacturer’s requirements, supplemented by condition assessment and operational experience where appropriate.

Is it better to repair or replace an old marine gangway?

Not necessarily. A structurally sound gangway may be suitable for refurbishment or upgrading rather than complete replacement. Controls, hydraulics, sensors, safety systems and other components may potentially be modernised while retaining suitable existing structure.

What is lifecycle support for a marine gangway?

Lifecycle support encompasses the engineering, inspection, maintenance, repair, refurbishment, modification and technical support required to keep an access system operational throughout its service life.

Why should lifecycle cost be considered when procuring marine access equipment?

Marine gangways can remain in service for many years. Considering lifecycle cost during procurement helps owners evaluate reliability, maintainability, component availability, service support and operational downtime alongside the initial capital cost.
