A survey of human factors on two state-of-the-art offshore supply vessels (OSVs) operating in the Norwegian Sea was performed by means of questionnaires. The purpose of the study was to examine whether human factors had been adequately addressed in ship design, how they were regarded by the crews, and whether design decisions were believed to have an effect on incidents on-board. The concept of human factors in ship design was operationalised into eight dimensions: habitability, workability, controllability, maintainability, manoeuvrability, survivability, occupational health and safety (OHS), and system safety. Inferential statistics were applied in order to draw conclusions, including means comparisons and multivariate regression analyses. The results show that human factors were given significant importance in the ship design. The level of accomplishment of human factors differs from one dimension to another. The highest satisfactory dimension was OHS and maintainability was the lowest, but still considered adequate. Design is revealed to have an impact on human factor ratings. Further, OSV design and human factor ratings are identified as having effects on particular incidents on board.

A master of a vessel must at all times know where their vessel is operating. Traditionally this is only thought of in the geographical sense; however, there is a clear necessity, for safe vessel operations, that the master knows where their vessel is in the hydrodynamic sense. This knowledge is also of prime interest to designing naval architects and route planners alike. Water depth has profound effects on vessel performance and to know When is Water Shallow? is the key to successful vessel operation and wash mitigation. The authors propose a series of characterisations to aid the definition of shallow-water and hence provide greater operational understanding. These characterisations cover typical vessel performance indicators such as resistance, propulsion, manoeuvring, etc., but also wash-specific performance indicators such as wave angle, wave decay, soliton occurrence and spectral output.

Enabling technology permits the naval architect to do more with fewer resources, increasing output, decreasing cost and improving productivity, with the resulting benefits being widely distributed in a worldwide economy. For example a bulk carrier’s energy consumption per ton-mile today is less than 3% of what it was a century and half ago – due to more efficient machinery, larger hulls with lower resistance per ton and improved propulsive efficiency, yet with higher speed and shorter port times.

Two land-based setups were tested at different locations using the same combined treatment technologies, to assess the effect of different control and treated tanks condition as well as overall effectiveness of a ballast water treatment system. The test procedure included a five day storage period of organisms in the control and treated tanks as specifically advised in the type approval procedure for shipboard and land-based tests described in the IMO Guideline ‘G8’. The configurations and materials of control and treated tanks used in each test location were different resulting in invalid test results at one testing location.

A study is presented of the effect of a pier on ship trajectories in currents. The current flow field around the pier is investigated. Experiments on ship manoeuvring and drift motion in the vicinity of a rectangular pier were carried out in a tank. Different current velocities and current angles were taken into account. The characteristics of the deviations of the ship trajectories from the initial course around the pier are investigated. Experimental findings indicate that the minimum required distance for safety navigation becomes larger with an increase of the current velocity. To obtain the details of continuous three-dimensional flow field around a pier, numerical simulation based on CFD calculations is conducted. The validity of the numerical simulation is demonstrated by comparison with experimental results.

For the cost effective & safe operation of ships and other marine assets it is mandatory to develop software solution tool which helps in timely maintenance with priority based to avoid both financial losses and operational downtime. Our idea is to propose concept to develop combined protection mechanisms system for Planned Maintenance system. The research is IDENTIFYING AND SCHEDULING DDOS-APPLICATION LAYER ATTACKS on onboard systems. Countering Distributed Denial of Service (DDOS) attacks are becoming ever more challenging with the vast resources and techniques increasingly available to attackers. In this paper, we consider sophisticated attacks that are protocol- compliant, non-intrusive, utilize legitimate. Application-layer requests to overwhelm system resources. We characterize application layer resource attacks on the basis of the application workload parameters that they exploit. Request flooding, asymmetric, repeated one-shot. To protect marine software-based servers from these attacks, we propose a counter-mechanism that consists of a suspicion assignment mechanism and a DDOS-resilient scheduler, DDOS Shield. In contrast to prior work, our suspicion mechanism assigns a continuous value as opposed to a binary measure to each client session, and the scheduler utilizes these values to determine if and when to schedule a session’s requests. This will be done through an integrated working of PMS and Inventory. PMS and Inventory, while performing definite tasks independently, will seamlessly integrate with each other. Further the installations will reside in the vessel, office and other office nodes, where information can be viewed and updated depending on your network of vessels. In office, the Inventory-PMS package will function in a client –server mode and in a single terminal on the ship with LAN for the purpose of accessing Internet. All the database updating and back-up maintenance shall be shown into the system to enable the user to do the database management without incurring exorbitant annual maintenance bills, which normally comes with all similar systems in the market.

Recently, the competitive environment is very tough in shipbuilding industry and under these circumstances, manufacturing a ship in a shorter time becomes significantly important in order to meet the customer demands. Therefore, it is hard to do that by using traditional manufacturing techniques. The shipyards located in Turkey usually have functional locations for the machines and this situation often causes longer production times. Instead of this, assembly lines should be redesigned as workshops in the shipyard. Prefabrication work unit is a good example in which an assembly line is needed to be designed. In this study, an assembly line design for prefabrication work unit was performed. For this, assignments of work operations to work shops were carried out by using Largest Set Rule Algorithm and some alternatives were created according to compare the different values of cycle time. These alternatives were simulated by using a production simulation program and the most appropriate assembly line design was presented.

The introduction of new regulations for Means of Access (MA) has led to an increase in the number and complexity of access openings, an increase in the size of the access openings in the ship’s structure, and a stricter maintenance regime which presents new challenges throughout the life of modern vessels. Several of the major issues at the design stage of Permanent Means of Access (PMA); the construction of ships; the application of protective coatings during new building, together with coating maintenance during the service lifetime; problems related to cleaning holds after cargoes have been removed; action by the Butterworth crude oil washing action and the challenges of maintenance in ballast tanks, are discussed in this paper.

Energy efficiency subject has been gaining importance in maritime sector. The compressed air is a valuable energy source in operational manner, by the reason of intrinsic lack of efficiency in pressurization process. Operational pressure and leakage rate are the major variables which affect operational efficiency of the system. This study aims to reveal potential energy saving for the compressed air system. To this end, several pressure ranges, 29-30 bars to 14-18 bars, and different leakage rates 2.4% to 45% are evaluated. After the data was obtained from ships, thermodynamic calculations had been carried out. Optimization of pressure saves 47.3% in daily power requirement, 58,2% in compressed air unit cost, 18.4 and 57.4 tons of reduction in fuel consumption and CO2 emissions in a year respectively. High leakage rates can cause 2.7 times more power and fuel consumption. Finally, operating load, as an important indicator of compressor, makes imperfections identifiable.

This study focuses on marine accident data regarding accidents that occurred between the years 1998-2010 for ships within the oil tanker category. Data in the study include accident reports, which are recorded in the Global Integrated Shipping Information System (GISIS) and country reports. Textual accident data in the GISIS database were tabulated, thus creating a systematic database. By using accident data from this database, a marine accidents map for oil tankers was developed via the ArcGIS 10 program, the areas with the highest accident incident rates were determined, and reasons for oil tanker accidents were revealed through the assessment of factors such as accident type, accident incident number, accident scope, ship tonnage, navigational sea area type, and accident’s impacts on the environment, economy and personnel. The study showed that very high risk areas for oil tanker marine accidents include the Singapore Strait and Oresund, and high risk areas are the Bristol Channel, Suez Channel, Strait of Hormuz, Great Belt, Piraeus, Hull, İstanbul Strait, and Amsterdam, respectively. The study also established that oil tanker accidents are related to ship tonnage and navigational sea area type.
