Mariner Safety Research Initiative

The Mariner Safety Research Initiative (MSRI) is a product of the collaborative effort between American Bureau of Shipping (ABS), Lamar University, and International Industry Partners. The MSRI includes a large international database of more than 100,000 maritime injury and close call (near miss) reports from over 31 data sources. Dr. Craig (PI), Dr. Curry (CO-PI), and Dr. Zhu (CO-PI) have worked on this project since 2010.

The incident databases have enabled us to create the MSRI, a public forum to share safety related materials and resources with not only industry partners, but the maritime industry as a whole. The incident data has been analyzed to identify trends, possible causes and lessons learned and develop safety related guidance materials including benchmarking statistics and relevant training tools. The overall goal of the MSRI is to improve mariner safety through sharing these data findings and providing safety related documents in a useable context.

The MSRI is broken up into two parts: the Public Site and the Industry Partner Site. The public site includes a general “sampling” of the documents and information that is available to the MSRI Industry Partners. For more information about this project, please see http://maritime.lamar.edu/.

Analysis of Ship Wake Wash on the Sabine Neches Water Way

Sponsor: Sabine Neches Navigating District

Research Team:
Dr. Victor Zaloom, Principal Investigator, Professor of Industrial Engineering
Drs. Qin Qian, Xing Wu, Mien Jao, Co-Principal Investigators, Dept. of Civil Engineering
Mr. Ben Kolkmeier, MESCE Student, Lamar College of Engineering
Dr. Keh-Han Wang, Professor of Civil Engineering, University of Houston

Dates: November 1, 2015 to April 30, 2017

Funding: $99,742

Project Summary:
The force and velocity of waves especially those produced by passing ships was measured at two strategic locations in the Sabine Neches Water Way. We measured flow velocity and wave characteristics including wave height, speed and orientation. Data analysis included wave height and wave energy especially those produced by passing ships. We obtained ship data from the USCG and correlated ship size, speed, and other parameters to wave impacts on the river bank and subsequent erosion. Erosion is a problem for two reasons. It causes loss of land but more important to our sponsor the Sabine Neches Navigation District the much of the material that results from river bank erosion ends up in the deep draft ship navigation channel thus reducing the depth of the channel. This material must then be dredges out of the Navigation channel and deposited elsewhere. It is usually deposited in placement areas. This is an expensive process. Phase II will be devoted to evaluating and recommending wave attenuation remedies that will result in less erosion and subsequent need to dredge the material from the navigation channel.

Design and evaluation of engineering systems to reduce erosion caused by ship generated and other waves will be accomplished in Phase II of this project.

Multimedia Learning of Engineering Economics through Role Play Gaming on a Mobile Platform

This project is increasing the knowledge base in how people learn using mobile computing technology by investigating the use of mobile technologies in an Engineering Economics course. The mobile technology allows a ubiquitous learning environment suitable to student lifestyle constraints. Specifically the project is studying the effectiveness of mobile technology in promoting deep and lasting learning of content, practice, skills and attitudes. Expected results include more student engagement and better performance on in-class exams. Smart phone apps developed by the project include role-playing games that allow students to interact with the app or with fellow students. The project uses formative and summative assessment to continuously guide the researchers in assessing the results. This study has application in a number of STEM education areas and therefore will significantly improve STEM education.  For more information, please see:

Maintenance Planning for Complex Systems in Dynamic Environments

Dr. Yisha Xiang is studying equipment failures in capital-intensive industries, such as oil and gas exploration, aerospace, and power generation, may threaten human lives and have significant environmental and economic impact. Many of these equipment failures can be traced to poor equipment maintenance. One criticism of existing maintenance planning is that the existing predictive failure models are not rich enough to accurately reflect degradation in dynamic environments. This project addresses the need for better planning models and analysis to enhance equipment reliability in capital-intensive industries. Successful development of this project will lead to fundamentally new perspectives on the application of reliability and maintenance optimization for complex engineered systems. Educational opportunities for students, including outreach to underrepresented minorities, is supported by the award.

Optimization of Vessel Scheduling Problem and Evacuation Decision Making Using Real-Time Location Data, and Their Economic Impacts: A Case Study for the Port of Houston

Dr. Berna Eren Tokgoz's project examines the highly chaotic environment during an evacuation. There may not be any pilots assigned to the ships and the risk of collisions or other accidents may get higher in these situations. The substances that are transported in a ship have various hazardous impacts during an evacuation process from the port.

Utilization of Unmanned Aerial Vehicles (UAVs) in Port Operations

This study focuses on: 1) establishing operational concept of UAS for effective port / terminal operations; 2) developing mathematical optimization model(s) to ensure coordinated optimal operations of vessels and UAVs; 3) developing a distributed control algorithms for UAV swarms; and 4) conducting risk analysis and resiliency study in UAV-aided port operations.

The project team includes:
(PI) Dr. Jaeyoung Cho, Assistant Professor, Department of Industrial Engineering
(Co-PI) Dr. Maryam Hamidi, Assistant Professor, Department of Industrial Engineering
(Co-PI) Dr. Berna Tokgoz, Assistant Professor, Department of Industrial Engineering

The purpose of this study is to lay the foundation for the development of future port system using unmanned aerial system (UAS). This study is composed of three detailed sub-topics. First, we study how to establish operational concept of UAS for effective port / terminal operations. Particularly, the focus of the research is on ensuring optimal routes generation of chemical tankers which are performing their respective loading / unloading operations. To optimize the problem, current chemical tankers operations in Houston ship channel are studied, and mathematical optimization model(s) are developing to ensure optimal operations of chemical tankers.  Second, we develop a mathematical model(s) to implement the concept of distributed control of multiple UAVs. This research focuses on decentralized control of UAVs in port operations based on game theory. Third, We conduct risk analysis and resiliency study on various safety & security problems that may arise when UAS is introduced in port operations.

Houston Ship Channel Closure Scheduling for a Bridge Construction

A methodology will be presented for a temporary closure scheduling of the Houston Ship Channel in order to construct a new bridge over the channel. A poor closure scheduling can cause a substantial loss in revenue for both port authorities and vessels. In this study, we will first analyze historical data for a good estimation of vessels’ traffic and shipping inside the channel, next we will develop a model in ARENA software to simulate the traffic and queue in the ship channel, under different closure scenarios. Constraints will be considered for the working rules of the channel such as daylight restrictions and combined beam rules. Finally, simulation results will be presented for number of the ships affected and also for the total ship time lost as a result of closures, and accordingly, the optimal channel closure schedule will be determined. Besides, policies would be recommended to the port authorities to substitute the current first come, first serve policy.  Please see Dr. Hamidi webpage for more information about her port research effort.
