They did not lose consciousness, but was confused and had pain. The crew member was examined onboard, was checked on throughout the night. The following morning the crew member mentioned swelling behind the ears and a pain in the ear canals. As the vessel was nearing port crew called Radio Medical Advice, the advise was the crew member could wait until arrival in port for further treatment.	Accident to person(s)
Cargo vessel suffered an engine fire resulting in no major damages or injuries. Cargo vessel suffered an engine fire resulting in no injuries and/or major damages. The fire services extinguished the fire which has been identified as coming from a generator that controls the bow thruster. The vessel was able to berth itself without any assistance and has undertaken measures for repairs.	Fire / Explosion
A recreational craft collided with a moored class v passenger vessel with the recreational subsequently sinking at mooring. A recreational craft was transiting in a canal when the skipper lost control and collided with a moored class v passenger vessel. The passenger vessel had no passengers or crew onboard but did have a maintenance man onboard. The passenger vessel sustained minor damage. The recreational craft returned to its mooring and subsequently sank at its mooring with no persons onboard. The vessel remains at its mooring in five foot of water.	Collision
A supply vessel passenger sustained a laceration to their finger. An offshore supply vessel passenger was passing through a door when the door closed and trapped the passenger's finger between the door and the frame. As a result of the incident, the passenger sustained a severe laceration to the tip of one of their fingers that required medical treatment at a shore side hospital. The incident occurred because the passenger put their hand on the frame which is not recommended best practice for safe passage through doors.	Accident to person(s)
Cruise ship's passenger lost their balance and fell resulting in a fractured wrist. Cruise ship's passenger lost their balance and fell forward striking their face and wrist on the floor. They sustained a fractured wrist.	Accident to person(s)
A cruise ship crewmember fell from the ladder of a bunkbed and fractured their arm. A cruise ship crewmember was climbing down from their bunk when the hook for the ladder broke, causing them to fall to the deck below and fracture a limb. The cause of the accident was attributed to the hook of the ladder broken, which was later repaired. The crew member signed off due to their injury.	Accident to person(s)
A container ship had an inadequate pilot ladder arrangement. A container vessel had an inadequate pilot ladder arrangement due to the fact that the stanchions were the wrong distance apart.	Damage / Loss Of Equipment
Cargo ship's pilot ladder did not conform to SOLAS regulations. Cargo ship's pilot ladder did not conform to SOLAS regulations. The forward magnet on the pilot ladder failed (ladder swung out and spreader became caught on the ship's gangway / accommodation ladder). Combination ladder arrangement with a freeboard 11.7M. Master confirmed that the magnet was replaced before the pilot disembarked, magnet failed again when Pilot was part way down the ladder.	Damage / Loss Of Equipment
A ro-ro cargo vessel had an inadequate pilot ladder arrangement. A ro-ro cargo vessel had an inadequate pilot ladder arrangement due to the fact that the weight was resting on a single step.	Damage / Loss Of Equipment
A cruise ship passenger fell down the stairs and fractured their ankle. A cruise ship passenger was descending the stairs whilst looking at their mobile phone when they missed a step, fell forward and landed on the floor twisting their ankle. The passenger later reported to the medical centre for treatment for a fractured ankle but has remained onboard. The area was inspected no obvious defects been observed.	Accident to person(s)
A cruise ship passenger rolled their ankle whilst walking and sustained a fracture. A cruise ship passenger was walking along between the chairs in a theatre area, when they rolled their ankle. After receiving medical care on board they were diagnosed with a fractured ankle as a result of the incident. The area of the incident was inspected by the crew and there were no defects found.	Accident to person(s)
Fishing vessel lost power resulting in being towed into harbour by another fishing vessel. Fishing vessel lost power resulting in being towed into harbour by another fishing vessel.	Loss Of Control
Cargo vessel's pilot ladder did not conform to SOLAS regulations A cargo vessel's pilot ladder did not conform to SOLAS regulations. Stanchions not extending from deck level. Railing's diameter bigger than required and difficult to grab.	Damage / Loss Of Equipment
Dive support vessel crewmember sustained a hand injury and was airlifted to shore. Dive support vessel crewmember sustained hand and finger injuries and was airlifted to shore. The injury details state that the casualty had a broken hand and finger and the decision to airlift was due to the vessel's location.	Accident to person(s)

MAIB Incident Type Dataset

The MAIB Incident Type Dataset contains short textual descriptions of marine accidents and incidents reported by the UK Marine Accident Investigation Branch (MAIB).
Each record includes a short narrative and a corresponding incident-type label (e.g. Grounding / Stranding, Fire / Explosion, Collision).
This dataset enables research and experimentation in maritime safety text classification and domain-specific NLP.

Dataset Details

Dataset Sources

Origin: Public summaries published by the UK Marine Accident Investigation Branch (MAIB)
Repository: github.com/iliamunaev/MAIB-Incident-Type-Classifier

Uses

Direct Use

Intended for:

Training and evaluating text-classification or topic-classification models
Exploring domain adaptation of general-purpose transformers (BERT, RoBERTa) to maritime text
Building incident-type classifiers or safety-report triage assistants

Out-of-Scope Use

Predicting liability or fault assignment
Using the data for individual identification or operational decision-making without expert review

Dataset Structure

Each record contains:

Field	Type	Description
`text`	string	Short incident description from MAIB report
`label`	string	Incident type category

Example

{
  "text": "Vessel grounded near Dover port after steering failure.",
  "label": "Grounding / Stranding"
}

Dataset Creation

Curation Rationale

To provide an open, structured dataset that supports NLP research and model evaluation in the maritime-safety domain, where labeled text resources are scarce.

Source Data

Data Collection and Processing

Extracted MAIB occurrence summaries from publicly available CSV and PDF data.
Combined “Short Description” + “Description” fields.
Cleaned text, removed duplicates and ultra-short entries.
Saved in JSONL format with text and label columns.

Source Data Producers

UK Marine Accident Investigation Branch (MAIB) investigators and report authors.

Source: https://www.gov.uk/government/organisations/marine-accident-investigation-branch

Annotations

No manual re-annotation performed; labels originate from MAIB’s published “Main Event L1” categories.

Personal and Sensitive Information

All data are public domain incident summaries with no personal identifiers.

Bias, Risks & Limitations

Class imbalance: “Accident to person(s)” and “Damage / Loss of Equipment” dominate the dataset.
Texts are concise and may omit contextual details.
Labels mirror MAIB taxonomy; may not generalize globally.

Recommendations

When fine-tuning models:

Apply class-weighting or data-augmentation for rare categories.
Validate predictions with domain experts for operational use.
