AIS
Automated Identification System (AIS): The AIS receives and transmits safety-related information including an identification code, type, location, direction, speed, and navigation conditions over the VHF band automatically to exchange information among vessels and between vessels and land. It may also use received data as part of information to analyze the vessel transportation situation of vessels with a total tonnage exceeding 500 tons.
BRM
Bridge Resource Management： Effective management process for bridge personnel to make full use of their individual and collective knowledge, information and skills, as an organization of Bridge Team. BRM is consisted by the steps of acknowledging situations, conveying information, recognizing problems, planning solutions, and putting the plans into effect.
DNV
Det Norske Veritas:
International accredited registrar and classification society headquartered in Oslo, Norway. World leading service provider which has strength in the field of energy industry.
DP（Dynamic Positioning）System
DPS automatically calculates external forces such as wind, wave, swell and tidal currents to maintain a vessel at a fixed point or navigate a set route with precision. It is indispensable for cable-laying ships, offshore wind power-related special-purpose vessels and seabed oil field-related offshore vessels to maintain their position precisely at a fixed point to do their work.
ERM training
Effective management process for engine personnel to make full use of their individual and collective knowledge, information and skills, as an organization of Engine Team. ERM is consisted by the steps of acknowledging situations, conveying information, recognizing problems, planning solutions, and putting the plans into effect.
K〜O
Maritime Safety Association
This is a public interest incorporated association that engages in public interest activities such as surveys and research in maritime safety, safety measure reviews for preventing maritime accidents, provision of safety information, and awareness raising activities. They organize navigation safety committees for issues such as increasing accepted vessel sizes and consolidate safe navigation measures.
Maritime Safety Committee
This committee is organized in such cases as when a vessel that is larger than anticipated at the time of design enters port facilities and shipping lanes, when there is offshore construction, and when shipping lanes or recommended shipping lanes are set or reviewed as specified by the port regulations or maritime transportation safety laws. The committee comprises academics, maritime stakeholders and governmental stakeholders to consider navigation safety measures.
Navigation Simulator Experiment
A full mission bridge navigation simulator offers the realistic feel of navigating a real vessel. This experiment simulates navigating in a variety of scenarios which enables the user to grasp physical impacts of the wind, tidal current, waves, depth of water, effect of side walls and so on in relation to the navigation of vessels. The simulation results, as well as subjective evaluation by academics, maritime stakeholders and governmental stakeholders, are analyzed to make a comprehensive assessment of the safety in entering and exiting a harbor.
OCIMF Guidelines
These refer to Mooring Equipment Guidelines prepared by The Oil Companies International Marine Forum (OCIMF).
When confirming the safety of the mooring, the mooring method and the wind speed limit for safe mooring are calculated based on the effects of external forces acting on the hull and the mooring capacity (capacity of mooring cables and mooring posts) according to the calculation method described in the guidelines.
P〜T
Significant Wave
The significant wave height is the average wave height of the highest third of the waves that are observed at one location during a certain period of time. This is considered to be about the same wave height as that which is visually observed by an experienced observer.
Technical Standards for Port Facilities
The standards are stipulated according to Section 2-2, Article 56 of the Port and Harbors Act, and are applicable to construction, improvement, and maintenance of port facilities in Japan. Safety considerations for the acceptance of ships will be conducted in accordance with this standard.
