It normally runs athwartships and is situated art. From the bridge the ship is nonna1ly navigated, and from there all activities on deck can be seen and controlled by the Captain or Officer of the Watch. Today the bridge of a modem ship is tota1ly enclosed by glass screens or windows to give protection from weather. In addition to the steering wheel or steering controls, the ship's main magnetic compass and a repeater from the gyroscopic compass are normally situated on the bridge. It also houses a chart table, radar scanners and a rich array of modem navigating and communication equipment. The type and layout of the wheelhouse and the bridge, as well as bridge wings, varies according to ship types and to the changes in modem technology in shipbuilding and navigation. Here is a layout of a modem wheelhouse.

The aim of the CIC is to check compliance with the applicable requirements of the SOLAS Convention, the overall status of the vessel's navigation safety, and the competency of crew involved in navigation operations. This inspection campaign will be held for three months, commencing from 1 September 2017 and ending 30 November 2017. A ship will only be subject to one inspection under this CIC during the period of the campaign. Navigation equipment have always been major inspection items for PSC inspections. The Tokyo MoU and the Paris MoU have conducted a joint CIC for SOLAS Chapter V concerning safety of navigation in 2008. The regulations for navigation equipment have undergone frequent changes according to a series of amendments to SOLAS Chapter V (safety of navigation). Electronic Chart Display and Information System (ECDIS) have assisted watchkeepers to maintain navigation safety and reduce the navigational workload since its application. Deficiencies relating to navigation equipment contribute a major proportion of the total deficiencies. From 2009 to 2016, a total of 174,559 deficiencies concerning safety of navigation were recorded, accounting for 15.27% of all deficiencies. Port State Control Officers (PSCOs) will use a list of 12 questions to assure that navigation equipment carried onboard complies with the relevant statutory certificates, the master and navigation officers are qualified and familiar with operation of bridge equipment, especially ECDIS, and that navigation equipment is properly maintained and functioning. If deficiencies are found, actions by the port State may vary from recording a deficiency and instructing the master to rectify it within a certain period of time to

Several technological advances have been seen the maritime domain to achieve higher operational efficiency and to address the generally recognised causes of most maritime accidents. The International Maritime Organization (IMO) endorses the use of best available technology to "drive continuous improvement and innovation in the facilitation of maritime traffic" in line with the goal of sustainable development. It is commonly acknowledged that modern technology revolutionized marine navigation, and presently it has a large potential to increase safety in navigation. However, the incorporation of new technologies in support of navigation also brought unforeseen critical consequences, contributing to unsafe practices, or even to accidents or incidents. Several issues were associated with human factors. To properly address the adoption of the newest technology in support of safe navigation, IMO established the e-navigation concept, currently under implementation.

Structural monitoring significantly contributes to greater and better knowledge of the real behavior of structures, having positive consequences both from an economic and social point of view. Currently, observation and monitoring is increasingly based on measurement systems that are an integral part of the structure. Sustainable engineering is something we have to keep in mind throughout the project, from planning and design to execution and operation. The Article will also mention 10 guidelines from the National Directive on Sustainable Development and Environmental Management of Professional Engineers, which was produced by Engineers Canada in 2016. The aim of these guidelines is to encourage Engineers to be proactive in protecting and managing a responsible environment. part inherent to the duties assumed by all engineers: researchers, academics, consultants, regulators or managers.

As the members of maritime industry awareness and sensitivity to the safety increase, more attention has been directed to ship safety. More people demand control over risk to which they are exposed and to model the uncertainties of risk and to seek measures of reduction. Therefore, this reality results in high cost in safety and money. The main purpose of the paper is to review the process of Formal Safety Assessment and to propose for a generic fishing vessel. In this circumference, a trial application of a formal safety analysis was attempted. An interactive risk table method is presented to produce an overall ranking for further attention in fishing vessel design and operation. Furthermore, a sample fault tree analysis is applied to find the relative importance of each component. Finally, some suggestions are made to reduce the risks and emphasized that more failure data needs to be collected on an industry basis and that much expert judgement from a qualitative point of view is ...

This best practice document was developed under the Rolling Deck to Repository project by a small working group comprised of the document authors. These recommendations are specifically for transmissometers installed within a research vessel's (RVs) scientific flow-through sea water (underway) system. They are not focused on transmissometers used for CTD/Rosette casts, though some information may be applicable. All underway transmissometers in the academic research fleet presently are WET Labs (henceforth Sea-Bird) C-Stars. Review of available sensors shows this will continue to be the most available and adaptive device. The Goal of this document is to provide best practices for operators that will improve access to transmissometer data and metadata to support routine data quality evaluation and science application.

Changes in properties of concrete bridges, during their usage, demand careful monitoring, registration of defects and damage, and corresponding repairs. Therefore, the serviceability mostly depends on the quality of their maintenance. Maintenance of structures is a big problem due to lack of money for repairs. Safety and functionality of concrete road bridges are of a special importance for the traffic flow continuity in different circumstances including after earthquakes, floods, as well as after vessel or vehicle impact on piers. This is why almost all countries use Bridge Management Systems (BMSs). They include the bridge inspection manuals, guidelines, report writing, bridge condition evaluation and determination of priorities (rating) for maintenance work or rehabilitation to achieve the design service life of bridges. This paper presents a comparative analysis of some documents of certain countries and associations, related to BMSs and their main components.
