Pilot Ladders at the heart of safe vessel transfers

Every day, pilots board and leave vessels under demanding conditions: moving water, limited visibility, varying freeboards and strict time windows. The pilot ladder is the single most important element in this transfer. International regulations such as SOLAS, IMO resolutions and ISO standards exist for one reason: to reduce risk in one of the most exposed moments of a vessel’s operation.

A pilot ladder must function reliably in ballast and loaded conditions, in calm seas and rough weather, and across a wide range of vessel designs. Any compromise in ladder quality, length, securing or certification directly affects the safety of pilots and crew.

Certified pilot ladders and practical guidance

Ned Marine supports shipowners with pilot ladder solutions that address both regulatory demands and operational reality.

• ISO 799-1 compliant pilot ladders, clearly marked and supplied with authentic certification
• MED-approved options for EU-flagged vessels and compatibility with class requirements such as DNV, Lloyd’s Register or ABS
• Different ladder configurations, including standard pilot ladders and robust Goliath pilot ladders with high-visibility, impact-resistant materials
• Guidance on correct ladder length, helping operators balance SOLAS compliance with safe, practical use
• Support for combination arrangements, ensuring correct overlap, clearance and independent securing of ladders
• Advice on inspection, ageing and replacement, including strength testing intervals and documentation management

By treating the pilot ladder as part of a complete pilot transfer arrangement rather than a standalone product, risks are reduced and compliance becomes manageable.

Discuss your requirements for pilot ladders

A pilot ladder is not a commodity. It is safety equipment that must match your vessel’s design, operating profile and regulatory framework. Contact us to discuss your pilot ladder requirements. Our specialists will help you select the right certified solution, ensure compliance with SOLAS, IMO and ISO standards, and support safe and reliable pilot transfers on every voyage.

Accommodation ladder applications across the maritime sector

Accommodation ladders are used in a variety of operational settings, including:
• Crew embarkation and disembarkation
• Boarding from service or tender vessels
• Shore access at ports, anchorages and terminals
• Boarding of surveyors, inspectors and technicians
• Controlled access during maintenance or operations
• Support for emergency evacuation procedures

Their versatility makes them an indispensable part of a vessel’s overall safety and access arrangement.

Why choose Ned Marine accommodation ladders?

Technical specifications

Accommodation ladders can be supplied with a range of technical features, including:
• Length options tailored to vessel size and freeboard
• Step width and tread surface variations
• Adjustable inclination to suit different quay and tidal levels
• Aluminium or steel construction

• Intermediate platforms and turntables
• Manual or electric winch arrangements
• Deck- or bulwark-mounted storage systems
• Optional lighting and lifeline attachment points

Specifications can be adapted to project requirements or class rules.

Installation and integration

Our accommodation ladders are designed for seamless integration with a vessel’s existing access arrangement. We provide guidance on:
• Mounting positions and deck reinforcement
• Safe deployment and retrieval procedures
• Winch system configuration and power requirements
• Inspection and maintenance routines in accordance with statutory rules
• Integration with gangways and other access systems

Proper installation ensures long-term reliability and reduces operational risk.

Accommodation ladder requirements

Accommodation ladders must comply with stringent international safety and performance standards to ensure reliable use in all operating conditions. According to IMO and SOLAS regulations, ladders must be constructed of approved materials, provide sufficient strength to support the expected load and be fitted with secure handrails, anti-slip steps and suitable platforms. The ladder must be capable of being safely deployed and recovered by a single trained operator, and the winch arrangement must include fail-safe braking mechanisms. In addition, vessels are required to maintain the ladder in good working order through regular inspections, lubrication and replacement of worn components. Class societies may impose additional requirements concerning structural integrity, mounting arrangements and periodic testing. These rules collectively ensure that accommodation ladders offer a safe, stable and compliant means of access throughout the vessel’s service life.

Vacuum Box Testing can be used on lap welds, shell to annular welds, butt welds, pressure vessels, piping systems, among many others. This method is great as it is capable of immediately locating any leaks. It can also detect the smallest leaks inside a given area.

Ned Marine’s professionals are trained and experienced in vacuum box bubble test methods in accordance with the ASME BPVC code, section V, article 10, Appendix II.

Please contact us if you require any more information or a quote.

What Is Vacuum Box Testing?

Vacuum Box Testing is a non-destructive method used to detect leaks and discontinuities in welds, tank bottoms, pipelines and pressure-retaining structures. By creating a controlled pressure difference inside a vacuum box and applying a contrast soap solution, even the smallest defects become visible as air bubbles. This technique is especially valuable in environments where safety and integrity are critical, such as maritime vessels, offshore installations and industrial storage tanks. It provides immediate, reliable visual confirmation without damaging the material.

How the Vacuum Box Method Works

The inspector applies a soap solution to the weld and places the vacuum box over it. When the vacuum pump creates negative pressure, any leakage path forces air through the defect, producing clear bubbles. This simple but effective mechanism allows rapid testing of long weld seams with consistent accuracy, even on irregular surfaces.

Where Vacuum Box Testing Is Most Effective

This method is ideal for large surface areas or components that cannot be pressurised internally. Typical applications include storage tank floors, ship hull plating, ballast tanks, pipelines, offshore skids, and pressure vessel attachments. It is particularly useful when other NDT methods—such as UT or radiography—are too costly, slow, or impractical.

Standards and Certification

Vacuum Box Testing at Ned Marine is performed according to recognised industry standards, including ASME BPVC Section V, Article 10, and applicable ASTM guidelines. Our inspectors are certified and trained to ensure precise execution and correct interpretation of all bubble indications. This guarantees compliance for marine, offshore and industrial inspection requirements.

Ensuring that hulls remain solid and clean.

Ned Marine is a proven industry leader in the field of cathodic protection, both as to anodes and ICCP. Designed to ensure that vessel hulls remain clean and organism free, our product range offers both customised and standard solutions, including many types of antifouling anodes, sacrificial anodes and Impressed Current Cathodic Protection (ICCP) systems. We understand how vital it is for seagoing vessels – or any ship, for that matter – to have high-quality, long-lasting anodes. That’s why Ned Marine anodes have a lifespan of up to five years.

Our in-house design and manufacturing capabilities enable us to supply customised anodes that can be installed anywhere on a ship’s hull, whatever the contours may be. We offer the full range of anode metals including zinc, aluminium and magnesium and they can be found on vessels all over the world.

Regular Inspections

Our experienced technicians provide regular inspections and maintenance programmes that are key to maximising the lifespan of anodes and ensuring effective protection against the corrosion that can result from electrolysis and biofouling organisms.

Ned Marine anodes are trusted worldwide, protecting ships, offshore structures, and critical maritime equipment from corrosion and biofouling. We offer three primary types of cathodic protection solutions, each designed for specific maritime applications.

• Sacrificial anodes: Made from zinc, aluminium, or magnesium, these protect vessels by corroding, leaving the ship’s hull intact, and extending the structural integrity of the vessel.
• Anti-fouling anodes: Releasing ions into the water prevents marine organisms like barnacles and algae from attaching to the hull, reducing drag, improving fuel efficiency, and cutting maintenance costs.
• ICCP: Impressed Current Cathodic Protection (ICCP) systems use an external electric current to prevent corrosion actively, automatically adjusting output to ensure optimal protection.

We also offer rope access inspections, a safe and efficient alternative for hard-to-reach areas, reducing the need for scaffolding or cranes.

Additionally, our NDT Training Centre provides certified training programs for personnel in ultrasonic, magnetic, penetrant, and visual testing.
