Ship Gangways: Rigging Right, Staying Safe

The gangway, or accommodation ladder, serves as the vital artery connecting a ship to the shore or another vessel, facilitating safe passage for crew, visitors, and supplies. While seemingly straightforward, the correct rigging and maintenance of these heavy and often cumbersome pieces of equipment are paramount. Any deviation from established procedures can lead to severe accidents, injuries, or even fatalities. This comprehensive guide delves into the intricacies of gangway operations, highlighting the critical importance of proper rigging, adherence to international standards, and the human element in ensuring maritime safety.

What is a Ship's Gangway?

At its core, a gangway refers to a platform, walkway, or ramp specifically designed to provide safe access between a ship and the land, or between two vessels during ship-to-ship (STS) operations. Its primary function is to facilitate the safe embarkation and disembarkation of personnel. However, a gangway's effectiveness and safety are heavily reliant on its proper rigging and continuous maintenance. Given the dynamic environment of a port or open sea, the gangway must be able to counteract movements arising from tidal streams, swell, ongoing cargo operations, and surge movements caused by other ships in the vicinity. Failure to account for these variables can render the gangway unstable and dangerous.

The Perils of Improper Rigging

Surveyors frequently report instances where a vessel's gangway or accommodation ladder has been rigged incorrectly, leading to significant safety hazards. These errors often stem from a lack of attention to detail, insufficient training, or simple complacency. The consequences can range from minor slips and falls to severe injuries or even drowning. It is not merely about having the equipment in place, but ensuring it is rigged and maintained to the highest safety standards.

Common Rigging Mistakes and Their Consequences

Several critical components of a gangway can be compromised if not handled correctly. For instance, rope guard rails must be kept taut to be effective; slack rails offer little protection against falls. Similarly, all stanchions must be properly fitted and securely in place. Neglecting these details can create dangerous gaps or weak points in the gangway's protective barriers. Furthermore, the walking surfaces – steps, handrails, and platforms – must be consistently kept free of oil, grease, and ice. A slippery surface is an accident waiting to happen, particularly in adverse weather conditions or during night operations. When the gangway is landed on the quay, careful attention must also be paid to the lifting bridle and/or davit arm, ensuring it is kept well above head height or moved completely clear to prevent personnel from being struck.

The Crucial Role of Safety Nets

One of the most common and dangerous rigging errors involves safety nets. These vital pieces of equipment are often found to be secured incorrectly, typically along each side of the ladder for its entire length. This method causes the net to hang uselessly below the steps, offering no protection whatsoever. For a safety net to be effective, it must lead away to the side of the ship, creating a broad catch area designed to intercept anyone unfortunate enough to fall off the gangway. An improperly rigged net provides a false sense of security, potentially exacerbating the risk rather than mitigating it.

Legal Framework and Best Practices

Adherence to international maritime legislation and guidelines is not just a matter of compliance; it's a fundamental pillar of safety. These regulations provide a clear framework for the construction, installation, maintenance, and inspection of embarkation and disembarkation means, aiming to standardise safety across the global fleet.

International Regulations and Guidelines

For ships constructed before or with gangways replaced after 1 January 2010, the IMO circular MSC.1/Circ.1331 – 'Guidelines for Construction, Installation, Maintenance and Inspection of Means of Embarkation and Disembarkation' – should be followed to the greatest extent possible. This circular works in conjunction with the Safety of Life at Sea (SOLAS) regulation II-1/3-9, which specifically addresses the means of embarkation on and disembarkation from ships. These IMO guidelines are indispensable for understanding the technical specifications and operational requirements that ensure the safety and reliability of gangways and accommodation ladders.

Ensuring Structural Integrity and Safe Arrangement

Beyond the legal framework, practical considerations for gangway arrangement are paramount. Every accommodation ladder must be of sufficient length. Even when tilted at its steepest permissible working angle, its lowest platform must remain less than 600mm above the waterline, even when the ship is empty and at its lightest draught. This ensures that access remains safe and manageable under various loading conditions. Furthermore, the gangway arrangement should facilitate direct access between the ladder and the landing on the ship's deck. The platform itself must be securely guarded by handrails and provide adequate handholds. When the gangway overhangs the water in port, a robust net or other suitable protection must be provided to prevent personnel from falling into the water. Each gangway must also clearly display a cautionary notice on each side, indicating the maximum and minimum permissible designed angles of inclination, along with the design and maximum load on the bottom end plate. Personnel using the gangway must be aware of the maximum number of persons allowed on it at any one time to prevent dangerous overloading. If the maximum operational load differs from the design load, this distinction must also be clearly noted on the marking plate.

Human Factors: Training and Vigilance

Even the most robust and well-designed gangway is only as safe as the people operating and using it. The human element, encompassing training, experience, and vigilance, plays a crucial role in preventing accidents and ensuring smooth operations.

Competence and Supervision

Given that gangways and accommodation ladders are heavy and cumbersome, their operation requires considerable skill and experience. Operating instructions should always be prominently posted in the vicinity of the boarding arrangements. It is absolutely essential that personnel tasked with breaking out, rigging, or operating the lifting gear for these ladders are sufficiently experienced, understanding the severe consequences a mistake could entail. Anyone unfamiliar with such tasks must be closely supervised by a responsible and competent person until they are deemed proficient. If inexperienced crew members are required to assist with gangway operations, a thorough risk assessment or job safety assessment must be carried out beforehand. This proactive step identifies any additional measures needed to reduce potential risks before commencing the operation, ensuring that all personnel are protected.

Essential Personal Protective Equipment (PPE)

Appropriate personal protective equipment (PPE) is non-negotiable when working with gangways. This includes personal floatation devices (PFDs) fitted with self-activating lights, whistles, and reflective material, especially when there is a risk of falling overboard. Safety harnesses of the arrestor type are crucial for anyone working at height, rather than mere fall restraints, which only limit movement. Fall arrestors must always be attached to suitable securing points fixed directly to the ship's structure. Many modern ships now feature dedicated gangway safety wires or fall inertia blocks, allowing for greater freedom of movement while ensuring safety. Importantly, a crew member's safety harness line should always be slightly taut, not fully slack. This slight tension can significantly reduce the impact of a fall, preventing an abrupt landing and mitigating the risk of severe injuries.

Dynamic Operations and Environmental Challenges

Gangway operations are rarely static. They are influenced by port regulations, specific vessel movements, and the ever-present environmental factors, all of which demand careful planning and execution.

Navigating Port Specifics and Ship-to-Ship Transfers

Ships must actively engage with local port authorities, as they may have varying interpretations and enforcement of safety requirements related to secure methods of access. Accidents frequently occur while rigging the gangway, particularly during the setup of stanchions or side ropes, especially when the gangway is overhanging the side and crew members are working at height. During ship-to-ship (STS) operations, the gangway should never be placed on a bulwark or the side railing of the vessel unless these structures have been specifically designed and certified to possess sufficient strength to support the gangway's weight and associated loads.

Securing Access: Lifebuoys and Pier Connections

As part of the gangway installation process, a lifebuoy equipped with a self-igniting light and a buoyant line must be readily available for immediate use in the vicinity of the embarkation and disembarkation area. This immediate availability is crucial for rapid response in the event of an overboard incident. Furthermore, positioning the gangway on the pier can present challenges, especially when bollards or other fixed structures obstruct the ideal landing spot. In such scenarios, various extensions, extra steps, small gangways, or portable walking bridges may be employed to connect the gangway seamlessly with the quay side. If such supplementary solutions are required, a comprehensive risk assessment must be carried out, and the solution must be formally approved by the Master. In some cases, obtaining class approval may also be necessary to ensure the integrity and safety of the improvised access arrangement.

Beyond Access: Gangway Security

While primarily a means of access, the gangway also serves a critical role in ship security, acting as the first line of defence against unauthorised boarding, particularly by stowaways.

Deterring Stowaways and Controlling Access

To effectively deter stowaways, vessels should conduct thorough risk assessments to systematically identify and address all onboard vulnerabilities, thereby managing the likelihood of security threats. The gangway is often considered the primary deterrent against stowaway incidents. In compliance with the Ship Security Plan (SSP) and the International Ship and Port Facility Security (ISPS) Code, ship crew members typically restrict access to the vessel to a single focal point – the gangway. All other unauthorised entry or exit points are secured and locked. This centralisation of access allows the crew to meticulously control boarding, conduct security checks, and perform routine inspections of baggage before permitting anyone on board. Stowaways sometimes attempt to gain access by disguising themselves as stevedores or other legitimate personnel. Therefore, gangway access must be a priority for security.

The Role of Watchkeepers

The gangway should be placed under the round-the-clock watchful eyes of dedicated gangway watchkeepers. Their duties include checking visitors' photographic identification (ID) and verifying them against the anticipated visitors list. The Ship Security Officer (SSO) plays a crucial role in identifying any unexpected visitors and taking appropriate measures to prevent potential stowaway incidents. Conducting a practical headcount helps the SSO track the number of visitors on board at any given time. While prevention is the primary strategy, the security level at individual ports may necessitate a combination of ship's watchkeepers, shore-based security personnel, or dedicated gangway watchmen, especially in high-risk locations. Vessel operators should always confirm specific requirements with local regulators and adapt their security protocols to the demands of each port. Furthermore, adequate lighting at night is crucial for gangway watchkeepers to monitor approaching small crafts or inconspicuous visitors effectively. In practical terms, vessels may raise the gangway during low tides or when they have a low freeboard, if permitted by the port authority, to further deter unauthorised boarding. While gangway watchkeepers significantly reduce the risk of stowaways, it is essential to recognise that comprehensive security extends beyond the gangway itself, embracing broader recommendations such as those in IMO Resolution FAL.13(42) – 'Revised Guidelines on the Prevention of Access by Stowaways and the Allocation of Responsibilities to Seek the Successful Resolution of Stowaway Cases'. This holistic approach is key to effective ship security under the ISPS Code.

A Comprehensive Guide to Gangway Safety

Ensuring gangway safety requires a multi-faceted approach, combining proactive hazard identification with diligent adherence to established safety practices.

Identifying and Mitigating Potential Hazards

Understanding the potential hazards associated with gangways is the first step towards preventing accidents. These include, but are not limited to:

• Loose or unsecured handrails.
• Insufficient lighting, particularly during night-time operations.
• Wet and slippery surfaces due to rain, spray, or spills.
• Unsecured or poorly positioned gangway netting, rendering it ineffective.
• The risk of falling off the gangway or ladders.
• Unforeseen movements of the gangway due to ship motion or external factors.
• Being struck by moving materials or equipment near the gangway.

Practical Safety Recommendations for Crew

To ensure the highest level of safety, the following practical tips and recommendations should be rigorously followed when using and maintaining gangways:

• The gangway should be free from any repair needs and particular attention paid to areas where aluminium meets steel. The absence or deterioration of an insulating gasket can lead to electrolytic corrosion, which will cause wastage and weakening of the gangway structure.
• Regularly inspect the gangway to ensure it remains in good condition and free from defects, such as cracks, corrosion, or damaged components.
• Maintain the gangway strictly according to the vessel’s planned maintenance system. This allows for the early detection of defective moving parts and ensures the equipment is always kept in optimal working condition.
• Secure the gangway firmly to the ship's structure to prevent any unintended movement or slipping, which could lead to instability.
• Trim the gangway correctly to ensure it is level and not inclined at an excessive angle. The angle should never exceed 30°, nor should it exceed the maximum permitted design angle of inclination as indicated on the marking plate.
• Ensure the gangway is clearly marked with its safe working load (SWL) to forewarn personnel boarding and prevent dangerous overloading.
• The gangway must be adequately illuminated, especially at night, to ensure it is clearly visible and safe to use.
• Keep the gangway clear of any obstructions that could impede safe passage for users.
• Ensure handrails are securely fitted on each side to provide reliable support and prevent falls.
• Only authorised personnel who have received specific training on gangway operations should be permitted to rig or adjust the gangway.
• Crew members should always wear a safety harness and lifejacket while rigging a gangway, particularly when working over water or at height.
• Exercise extreme caution when using the gangway, especially when carrying heavy or bulky items, as these can affect its balance and stability.
• Crew should always wear proper footwear that provides excellent traction and grip to prevent slips and falls on potentially wet or uneven surfaces.
• Officers on duty or dedicated gangway watchmen should inspect the gangway regularly throughout its use to identify and address any developing issues.
• All visitors should be meticulously verified against their photo ID and the visitor list.
• A proper headcount should be carried out to accurately determine the number of visitors boarded.
• A comprehensive risk assessment should be completed prior to rigging, and the gangway should be secured as per the company’s safety management system (SMS), Ship Security Plan (SSP), and any provided checklists.
• The Master should engage proactively with the port authority or terminal representative to discuss the optimal placement of the gangway, ensuring the available landing area is sufficient to accommodate surge movements or the natural rise and fall of the tide.
• As a matter of best practice, the 'Code of Safe Working Practices for Merchant Seafarers' (COSWP) is widely recognised and provides invaluable guidance for safe working practices in a maritime environment.

Real-World Consequences: A Case Study in Complacency

The dangers of complacency and improper gangway management are starkly illustrated by real-world incidents. Consider a case from 2006 involving a fall from a gangway. After mooring, the vessel's main shore gangway was lowered to the correct height. A connecting gangway, often referred to as a 'brow', was then placed on the main gangway, with its other end secured to the ship's rails. A ship's safety net was deployed, and a step ladder provided access to the deck. A lifebuoy was positioned nearby. A duty AB manned the gangway continuously. Cargo operations commenced, with a planned stoppage for a 'bore tide' passage. Safety checks were carried out and deemed satisfactory.

However, as cargo loading was suspended, the brow was unlashed from the ship’s rails and pushed out onto the shore's main gangway, assisted by a terminal operator. Crucially, it was left halfway on the main gangway, with the other half overhanging, creating a dangerous 'see-saw' effect. The access to the main gangway was not sealed, nor were any warning signs posted or barriers erected to deny access. At 0900, crew were called to stations, and no one was paying particular attention near the gangway as it was out of view from the aft stations, and no visitors were expected.

At 0918, main engines were tried. Just two minutes later, at 0920, a person from the Seaman's Club attempted to board the vessel, despite being verbally warned by the terminal operator. This attempt caused the brow to overbalance, and the man fell into the water along with it. The quick action of a cadet raising the alarm and the immediate deployment of the lifebuoy by the duty officer were critical. Fortunately, the man was not injured and managed to pull himself onto the jetty foundation. The ship's crew managed to recover the brow, and port authorities were informed. The rescue squad eventually removed the 60-year-old casualty from under the jetty, taking him to hospital for shock treatment.

This incident offered profound lessons:

1. Nothing should be taken for granted. Both ship and shore assumed no one would visit, leading to complacency and the brow not being properly secured or removed, nor any warnings displayed.
2. Access must be secured. Notices should always be displayed, or access completely sealed off to all visitors once the ship-shore access is compromised or temporary.
3. Terminal operator's responsibility. The terminal operator was slack in their duty, failing to impose their authority to prevent the person from attempting to board, even after a verbal warning.
4. Vigilance and physical intervention. The person ignored the verbal warning, possibly due to inattention, other distractions, or even an age-related hearing impairment. Regardless, it was the terminal operator's duty to physically deter or remove the individual from the dangerous situation.
5. Duty officer's accountability. The duty officer felt responsible for the accident, highlighting the heavy burden of responsibility in maritime operations, even when circumstances seem beyond immediate control.
6. Prompt emergency response. The quick and efficient actions of the ship's staff in deploying the lifebuoy and recovering the brow helped resolve the situation and bring it under control, preventing further injury.
7. Continuous improvement in rescue. While satisfactory, the rescue personnel's response time could have been improved, as it took 30 minutes from their arrival to the successful removal of the person from under the jetty.
8. The gravity of the risk. Despite the fortunate outcome of no injury, this accident could easily have been fatal, underscoring the severe risks associated with improper gangway management.

Frequently Asked Questions (FAQs)
