Categories of Maritime (Ship) Accident Types

Lloyds Maritime Information Services (LMIS) has a casualty database which divides the maritime (ship) accidents into the following categories:

1. Foundered – includes ships which sank as a result of heavy weather, leaks, breaking into two, etc, and not as a consequence of other categories such as collision etc.

2. Missing vessel – includes ships that disappeared without any trace or witnesses knowing exactly what happened in the accident.

3. Fire/explosion – includes ships where fire/explosion is the first event reported, or where fire/explosion results from hull/machinery damage, i.e. this category includes fires due to engine damage, but not fires due to collision etc.

4. Collision – includes ships striking or being struck by another ship, regardless of whether under way, anchored or moored. This category does not include ships striking underwater wrecks.

5. Contact – includes ships striking or being struck by an external object, but not another ship or the sea bottom. This category includes striking drilling rigs/platforms, regardless of whether in fixed position or in tow.

6. Wrecked/stranded – includes ships striking the sea bottom, shore or underwater wrecks.

7. War loss/hostilities – includes ships damaged from all hostile acts.

8. Hull/machinery damage – includes ships where the hull/machinery damage is not due to other categories such as collision etc.

9. Miscellaneous – includes lost or damaged ships which cannot be classified into any of the categories 1 through 8 due to not falling into any of the categories above or due to lack of information (e.g. an accident starting by the cargo shifting would typically be classified as miscellaneous).

Above is also referenced in Wartsila website. Man Over Board (MOB) event, a person falling into water, is not referenced in the above listing.

 

However;

IMO accidents website, Global Integrated Shipping Information System (GISIS), refers to Man Over Board as another accident type, which may end with a death or injury. We would like to refern the following two of our publications for the details of MOB and Collision accident types:

Abstract

Our research study indicates that, over the past few decades, the expected decrease in the number of maritime accidents has not occurred. The statistics show the collision and contact types of marine accidents have always been the most frequent. Primary causes that contribute to ship collisions were collected from 513 collision accidents reported since 1977, which is the date the Convention on the International Regulations for Preventing Collisions at Sea, 1972 (COLREGs) came into effect. The root causes of ship-to-ship collisions were determined statistically. Qualitative and quantitative analyses were carried out using the Fault Tree Analysis (FTA). This provided the probability and importance of the primary causes contributing to the ship collision accidents and defined minimal cut sets. Results show that the violation of the COLREG Rules is the most important and effective factor for collision accidents. Therefore, further analysis was conducted and the results showed which type of COLREG Rules mostly violated statistically. The primary causes were also examined by Multiple Correspondence Analysis, and it was determined that maneuvering and perception errors were the most effective factors in collision accidents. The results represent the cause statistics of the ship-to-ship collision accidents that occurred in the last 43 years. Considering the collision accident reports data, our results show %94,7 of collision accidents are related to human error.

Capture GDS Vision in the Engine Room Simulator Development

Posted on by

In recent years, the maritime industry has seen a significant push towards technological advancement and stricter safety and operational standards. As vessels become more sophisticated and regulations evolve, the role of well-trained onboard maritime personnel becomes increasingly essential. In this context, the SIRE 2.0 program and GDS Ship Engine Room Simulator represent pioneering tools designed to equip maritime crews with deep technical skills necessary to meet new demands and improve the safety and efficiency of maritime operations.

Understanding SIRE 2.0 and Its Impact on Maritime Training

The Ship Inspection Report Programme (SIRE) has long been a fundamental tool in maintaining safety and operational standards across the maritime industry, particularly for tanker operations. Launched by the Oil Companies International Marine Forum (OCIMF), the program provides a comprehensive inspection system that evaluates the condition and operations of vessels. However, with the growing complexity of modern vessels and stricter environmental and safety regulations, the traditional SIRE program required enhancements to address these evolving needs. This led to the development of SIRE 2.0, an upgraded version that integrates data-centric inspection methodologies with a stronger focus on crew competency, operational excellence, and technical skills.

One of the key features of SIRE 2.0 is its focus on assessing the competency of crew members in handling complex equipment and operations. Rather than focusing solely on vessel condition, SIRE 2.0 evaluates the practical skills, knowledge, and decision-making abilities of onboard personnel. This ensures that crew members are not only familiar with equipment and operational standards but are also capable of responding effectively to critical situations.

The emphasis on crew competency in SIRE 2.0 aligns with the industry’s shift toward a human-centered approach in safety and operational excellence. This paradigm shift means that training programs must go beyond traditional instruction and delve into more practical, technology-driven skills, which is where simulators like the GDS Ship Engine Room Simulator come into play.

The Role of the GDS Ship Engine Room Simulator in Skill Development

The GDS Ship Engine Room Simulator is an advanced training tool that replicates the engine room environment of modern vessels, providing maritime personnel with hands-on experience in a controlled setting. This simulator covers a wide range of critical systems found in ship engine rooms, including propulsion, auxiliary machinery, electrical systems, and emergency protocols. By using the simulator, crew members can practice their skills, refine their decision-making processes, and gain confidence in handling complex systems without the risks associated with real-world errors.

The simulator allows trainees to engage in realistic scenarios, such as equipment failures, power management issues, and environmental challenges. This training is invaluable in helping them develop deep technical skills needed to respond effectively under pressure. Given the increasing complexity of ship machinery, which often integrates digital and automated controls, such simulator-based training ensures that personnel are well-prepared for both routine and emergency operations.

Developing Deep Technical Skills with SIRE 2.0 and the GDS Simulator

By integrating SIRE 2.0’s competency standards with the practical capabilities of the GDS Ship Engine Room Simulator, maritime training institutions can foster deep tech skills that are essential in today’s high-stakes maritime environment. Training programs using these tools can address various aspects, including:

Operational Readiness: By simulating real-life engine room conditions, the GDS simulator enables personnel to develop an intuitive understanding of systems and processes, which aligns with SIRE 2.0’s focus on crew readiness and situational awareness.

Crisis Management and Decision-Making: The simulator provides scenarios that replicate emergency situations, allowing trainees to practice crisis response, prioritize actions, and make critical decisions under pressure.

Technical Proficiency: The GDS simulator helps personnel develop advanced skills in troubleshooting and maintaining complex machinery, which is crucial for achieving SIRE 2.0’s standards for operational excellence.

Environmental Compliance: With a growing emphasis on environmental regulations, the simulator enables crew members to familiarize themselves with compliance standards and practice procedures that reduce environmental impact, such as optimizing fuel usage and managing waste effectively.

Safety Protocols: Through realistic training scenarios, the simulator reinforces safety protocols, ensuring that personnel can identify and mitigate risks, which is a core component of the SIRE 2.0 inspection program.

Abstract

Flag states must issue their maritime investigation reports in accordance with the International Maritime Organization (IMO) circulars with the inclusion of ‘lessons learned’ items from recorded accidents or incidents. To identify the root cause of an event, there must be enough detail of information about the investigated event presented in reports. The information included in reports may help identifying the procedural deficiencies or technical challenges. Considering the Man-Over- Board (MOB) events as a sub group of maritime accident  nvestigations, authors systematically reviewed over 100 reports containing MOB events in this study.

In this study, reports are reviewed and major differences in formats as well as level and type of information are recorded. A systematic methodology for reviewing and reporting the overall information retrieved from maritime accident reports is presented. To cover all information from reviewed reports, 113 information items are identified. An associated standard form is developed for use in extracting information from all investigation reports. Enabling the data collected systematically from reports, issued by the world maritime accident reporting states and agencies, and successively populated into a database for overall analysis, this form is called “Maritime MOB Events Investigation Form (MEI Form)”. This paper presents the content of the MEI Form and demonstrates the methodology of use for retrieving, formatting and analyzing the information from the MOB investigation reports using case examples.
