Passenger ferry operators run tight maintenance schedules and high crew rotation. The navigation bridge is the operational centre of a vessel that may complete four, six, or more sailings in a single day. Bridge window fittings that fail compliance checks during a port state control inspection, degrade under repeated thermal cycling, or require unplanned replacement do not simply create a maintenance expense. They disrupt operations, create liability, and in a passenger ferry context, they attract more scrutiny than on most other vessel types.
This guide is written for passenger ferry operators specifying or reviewing bridge window fittings, and for outfitters procuring on their behalf. It covers the compliance requirement, the procurement risk of specifying incorrectly, and how SOLASOLV® Type Approved anti-glare screens are specified for passenger ferry applications across a range of operating conditions.
Why Passenger Ferries Have Specific Compliance Requirements
Passenger vessels operate under a more intensive regulatory framework than most commercial vessel types. SOLAS Chapter III covers life-saving appliances and arrangements for passenger vessels. SOLAS Chapter V covers safety of navigation and applies to all vessels, including the requirement under Regulation 22 that navigation bridge windows and their fittings do not impair the field of vision of the officer of the watch.
Bridge window fittings — including anti-glare screens and roller blinds — are within the scope of PSC inspection under SOLAS Chapter V. A fitting that lacks valid Type Approval from a recognised classification society can be recorded as a deficiency. On a passenger ferry operating regular scheduled services, PSC inspections occur frequently. A vessel completing multiple sailings per day in and out of ports covered by Paris MOU, Tokyo MOU, or other PSC regimes may be inspected multiple times each year. The deficiency record from a non-approved fitting does not disappear between inspections.
Passenger ferries are typically classed with Lloyd’s Register, DNV, or Bureau Veritas depending on the flag state and the operator’s preference. Classification society surveyors conducting renewal surveys also inspect bridge equipment. A non-approved fitting found during survey may result in a condition of class requiring replacement before the survey is closed.
The Procurement Risk for Outfitters Supplying Passenger Ferry Operators
An outfitter procuring bridge window fittings for a ferry operator carries direct accountability for the compliance of what they supply. If a non-approved fitting is installed and subsequently identified as a deficiency by a PSC officer or classification surveyor, the operator will look to the outfitter as the source of the problem. The documentation trail — or its absence — determines where liability sits.
Protecting a procurement decision requires verifiable documentation at the time of supply: the Type Approval certificate from the approving classification society, the certificate number cross-referenced against the society’s public register, and a record that the approval covers the specific product and specification supplied. Without this documentation, the outfitter has no evidence base for the compliance of what they installed.
Technical documentation for SOLASOLV® products, including Type Approval certificates from all four classification societies, is available from the Solar Solve downloads page.
The outfitter who specifies a non-Type Approved product for a passenger ferry navigation bridge is not saving their client money. They are transferring risk to themselves.
What SOLASOLV® Provides for Passenger Ferry Applications
Type Approval Across All Four Classification Societies
SOLASOLV® is the only marine anti-glare screen in the world to hold simultaneous Type Approval from Lloyd’s Register (awarded May 2001), ABS (awarded September 2001), DNV (awarded July 2002), and RINA. For passenger ferries classed with any of these societies, SOLASOLV® screens are certifiable without additional assessment. There is no need to check approval compatibility against the vessel’s class.
Performance in High-Cycle Environments
A passenger ferry completing multiple sailings per day subjects its bridge fittings to repeated thermal cycling as the bridge environment heats and cools with each departure and arrival. SOLASOLV® screens are manufactured to maintain dimensional stability and performance consistency under repeated thermal cycling. A fitting that warps, degrades, or loses optical clarity under cycling compromises both compliance and crew visibility.
Sustained Glare Reduction on Fixed-Route Operations
Passenger ferries often operate on fixed routes with predictable solar angles at specific times of day. A crew member completing the same route multiple times daily is exposed to the same glare conditions at the same points on each sailing. SOLASOLV® screens reduce solar glare by up to 93 per cent, directly reducing accumulated visual fatigue for crew on high-frequency fixed routes.
UV Protection for Crew on High-Frequency Routes
UV exposure for crew on regular sailings is cumulative. SOLASOLV® screens reject up to 99 per cent of UV radiation while maintaining a completely clear, undistorted outward view. This protects crew on high-frequency routes from UV accumulation without affecting navigation visibility.
SOLASOLV® vs ROLASOLV® — Which Product for Which Passenger Ferry Application
| Application | Recommended Product | Reason |
| Open bridge (high glare exposure) | SOLASOLV® anti-glare screen | Maximum glare and heat rejection; maintains clear outward view; Type Approved for navigation bridge use |
| Enclosed bridge (full climate control) | SOLASOLV® or ROLASOLV® depending on solar exposure level | SOLASOLV® where direct solar glare is the primary issue; ROLASOLV® for general solar management in fully enclosed, air-conditioned bridges |
| Mixed route (variable solar angle) | SOLASOLV® anti-glare screen | Consistent performance across variable solar conditions; no adjustment required between routes |
| Retrofit of existing installation | SOLASOLV® to match original Type Approved specification | Ensures compliance continuity; replacement product must carry same or equivalent Type Approval as the original |
| Newbuild specification | SOLASOLV® specified at drawing stage | Type Approval documentation available for classification society review during build; certified drawings available on request |

Procurement Documentation Checklist for Outfitters
Before supplying bridge window fittings for a passenger ferry, outfitters should complete the following steps and retain documentation for each.
- Obtain a current Type Approval certificate from the supplier, confirming the approving classification society, certificate number, and product specification
- Cross-reference the certificate details against the approving society’s publicly accessible product register to confirm the approval is genuine and current
- Confirm the Type Approval covers the specific product variant, size, and specification being ordered — approval does not automatically extend to related products
- Confirm the approving classification society is appropriate for the vessel’s class — check with the operator’s technical team if uncertain
- Record the certificate number, approval society, and product specification in the vessel’s procurement file
- Retain a copy of the Type Approval certificate with the installation record for the vessel
- Confirm with the operator that the documentation will be available for PSC inspection or classification survey on request
- For newbuild projects, request certified technical drawings from the manufacturer at the specification stage to support classification society review during build
What Ferry Operators Should Ask Their Outfitter Before Sign-Off
Does this product carry Type Approval from a recognised classification society?
This is the primary compliance question. The answer should be yes, with the approving society named and a certificate number provided. A product with CE marking but without classification society Type Approval does not satisfy the SOLAS navigation bridge requirement.
Is the Type Approval current and does it cover the exact product being installed?
Type Approval is product-specific and time-limited in some cases. A certificate that has expired, or that covers a different model or variant from what is being supplied, does not constitute valid approval for the fitted product.
Can you provide documentation I can present to a PSC officer or surveyor?
The documentation should be in a format that can be presented immediately during an inspection — the original certificate or a clear certified copy, referencing the specific product and the vessel installation.
Is the product appropriate for the vessel’s classification society?
While most major societies accept approval from Lloyd’s Register, DNV, ABS, and RINA, operators of vessels classed with a specific society should confirm that the product’s approval is recognised under their class.
What happens if this product needs replacing at short notice?
Understanding the outfitter’s ability to supply a like-for-like approved replacement at short notice is a practical operational question. SOLASOLV® products are manufactured in South Shields, UK and available through Solar Solve’s network. For enquiries, see the contact Solar Solve page.
Frequently Asked Questions
Are SOLASOLV® screens suitable for passenger ferries classed with Bureau Veritas?
SOLASOLV® screens hold simultaneous Type Approval from Lloyd’s Register, DNV, ABS, and RINA. Bureau Veritas operates its own approval process. Operators of BV-classed vessels should confirm with their classification society whether approval from one of the four societies whose approval SOLASOLV® holds is accepted for their vessel. Solar Solve can provide full Type Approval documentation to support that review.
How long do SOLASOLV® screens last in a high-cycle passenger ferry environment?
SOLASOLV® screens are manufactured to maintain dimensional stability and optical performance under repeated thermal cycling. Solar Solve’s quality management system has been in continuous operation since 1991 and is audited externally every year as part of the Type Approval renewal process. Specific product lifetime questions can be directed to Solar Solve’s technical team via the technical information page.
Can SOLASOLV® screens be retrofitted to replace existing non-approved fittings on a passenger ferry?
Yes. SOLASOLV® screens are available for retrofit installations. For compliance continuity, the replacement product should carry Type Approval from a classification society recognised by the vessel’s current class. SOLASOLV® holds approval from Lloyd’s Register, DNV, ABS, and RINA, covering the majority of passenger ferry operators. Contact Solar Solve with the vessel specification to confirm the appropriate product.
Does the high frequency of passenger ferry operations affect the compliance requirement?
The compliance requirement itself is the same regardless of sailing frequency — SOLAS requires that navigation bridge window fittings carry valid Type Approval from a recognised classification society. However, the practical consequence of non-compliance is greater for high-frequency operators. A vessel completing multiple sailings per day through PSC ports has greater exposure to inspection, and a compliance deficiency has a larger operational impact on a vessel that cannot be taken out of service without significant disruption.
