Legislation/celestial Flashcards
What is the purpose of the ISM code
Set by the IMO - under SOLAS chapter 9.
Its primary purpose is to ensure the safety of ships and the prevention of marine pollution.
What are the aims of the ISM code
Set guidelines to standardise safe practices
Apply a SMS on board vessels to ensure compliance with international regulations
Promote a safety culture on board through the continuous improvement of safety systems and implementation of risk assessments.
Define the responsibilities of ship owners, masters, crew and management.
How does HSE (health, safety and environment) get implemented onto vessels?
Through the SMS, Particularly through:
Drills,
Training
Audits/inspections
Risk assessments
Routine inspections
Briefings
Reporting
What is the HSWA
Health and safety at work act (2015). This is the primary legislation that sets out the legal framework for workplace health and safety in New Zealand. It places duties and responsibilities on employers, employees, and others to ensure a safe and healthy work environment. The HSWA also outlines the role and powers of WorkSafe.
What are some non adjustable sextant errors
These will be tabulated into the calibration certificate in the sextant box.
Centring error (index bar/index mirror not rotation from same point)
Graduation error (Faulty/inaccurate markings)
Shade error (shade surfaces not being parallel)
Prismatic error (two mirror surfaces not being plane and parallel to each other)
Collimating error (telescope not parallel to plane of the sextant)
What are the main three adjustable sextant errors
Perpendicularity error (Mirror isn’t perpendicular to plane of sextant) Look directly into the mirror and line the frame up.
Side Error
Index Error
What is Nominal, geographical and Luminous range and how would they be used
Nominal is the range shown on the chart, its how far you would see it with a visibility of 10 NM
Luminous is the maximum range you could see the light with existing visibility conditions
Geographic range is the range at which the light can be raised/dipped depending on the height of the light and observer.
Can be used for finding a range from an object when raising or dipping a light, using the luminous range table in the (Nz) almanac. If the luminous range is greater than the geographic range, you can use the light tables by raising or dipping it to get a range. Nominal range is given on the chart.
What information would you find in a vessels SMS
Roles/Responsibilities
Reporting / investigation
Emergency procedures
Documentation and record keeping
Security Measures
Audits/Inspections
LSA/FFE servicing intervals
Training and competency
SOPs
Where would you find tidal information?
Nz (almanac)
Admiralty Tidal tables
What are ALRS volumes 1-5
Can Randy Maidens Make Good Partners
1- Coast radio stations
2 - Radio/ Nav aids
3 - Maritime safety info
4 - Meteorological stations
5 - GMDSS
6 - Pilotage info / VTS
What are your initial actions after sighting a flare
Call master
Fix position
Take bearing to the signal
Monitor distress signals
Monitor X band radar for SART
Check chart and plot course in direction of bearing
Potentially alert all crew and ready first aid equipment and rescue boat
What are some of the limitations of RADAR
- Blind and shadow Sectors
- Indirect paint in these sectors
- Bearing discrimination (scanner size)
- Range discrimination (pulse length)
- Max detection range (height of scanner and target)
What are some of the Publications that you would use in the Appraisal stage of passage planning
NP100 - mariners hand book
Admiralty Vol 1 - 6
Almanac
Ocean currents and weather charts
Tidal tables
Charts
What is LRIT
Long range info and tracking on vessels (purpose is for security and safety)
It sends continuous updates of the vessels position to flag.
Compulsory for all vessels over 300GT.
What publications may you carry electronically
Any admiralty publications that start with AD, eg AD11
Where do you get your chart corrections from?
Notices to mariners ( Weekly for uk, Two weeks in NZ)
What is the cumulative list and annual summary of NTM
Cumulative list is put out twice annually and has all of the NTM from the past year
Annual is a yearly summary of notices such as publications and distress signalling (doesn’t change much)
What are the sewage discharge requirements under MARPOL
ANNEX 4.
Must be on route moving at least 4knots and outside 3NM for macerated. 12NM if not macerated. Outside of special areas.
What RADAR is mandatory to carry and what are its attributes
X band-
3cm wave length
9-10 GHz frequency
Affected by weather sea rain and fog
What does ecdis have to adhere to
Standards set by the IHO such as
S57 - Standards for hydrographic data
S52 - specifications for display
What does fog do to diminish radar
It absorbes the pulse which limit detection range
What determines a good radar paint
S ize
C omposition
A spect
T exture
S hape
What is IAMSAR
International aeronautical and maritime search and rescue.
A guide to search and rescue patterns and plans for vessels and aircraft
What are the characteristics of S band radar
10cm wavelength
Lower frequency
Better for visuals through sea rain and fog
