An allision occurs when a moving vessel strikes a stationary object, such as a dock, crane, or another ship. This is a common risk in shipyards and can lead to significant financial and legal complications.

For those of us operating in water transport and repair, understanding liability in these incidents is critical to safeguarding operations and avoiding unnecessary costs.

Under maritime law, liability for an allision generally falls on the moving vessel. The rationale is straightforward: stationary objects cannot take action to avoid a collision. However, this presumption of fault is not absolute. A vessel owner can argue against it by proving that external factors, such as improper placement of the stationary object, contributed to the incident. Other defenses might include evidence of extreme weather or negligence by the shipyard or port authority.

Allisions in shipyards often result from human error, mechanical failure, or poor environmental conditions. Navigational mistakes during docking maneuvers or engine malfunctions can easily lead to accidents. In some cases, poorly maintained shipyard infrastructure, such as faulty mooring lines or inadequate signaling systems, exacerbates the risk. Environmental factors, including strong winds or currents, further complicate the situation, making careful planning and execution vital.

From a legal perspective, allisions can result in various claims. Shipyards may seek compensation for damage to their property, which can include costly repairs to docks or equipment. If third-party vessels or equipment are affected, additional liability may arise. Environmental damage, such as a fuel spill, can bring significant regulatory fines and reputational harm to the shipowner. Insurance plays a crucial role here, but it is essential to ensure policies are comprehensive and not riddled with exclusions or high deductibles that leave gaps in coverage.

Defending against claims requires prompt and thorough action. Documenting the scene of the allision is essential. Photos, videos, and witness accounts can provide critical evidence. Maintenance records for the vessel may also prove valuable, demonstrating that the ship was in good condition before the incident. If environmental factors played a role, weather reports can help support a defense. In some cases, investigating the shipyard’s conditions and practices may uncover negligence, shifting part of the blame away from the vessel owner.

Preventing allisions requires a proactive approach. Crew training is paramount; a well-prepared team is less likely to make errors during docking or maneuvering in tight spaces. Pre-arrival planning, including analyzing weather and berth conditions, reduces uncertainty. Regular inspections of the vessel’s mechanical systems ensure reliability and minimize the chance of unexpected failures. Clear communication with port authorities and shipyard personnel during operations is equally important, helping to avoid misunderstandings that can lead to accidents.

Shipyard allisions are a significant risk for maritime businesses. For small family operations, they represent not only financial burdens but also potential threats to reputation and relationships with partners. Understanding the legal framework surrounding liability, maintaining strong operational practices, and staying vigilant against external risks are essential to navigating these challenges effectively.
