Who can use the inshore traffic zone?
(i) A vessel shall not use an inshore traffic zone when she can safely use the appropriate traffic lane within the adjacent traffic separation scheme. However, vessels of less than 20 meters in length, sailing vessels, and vessels engaged in fishing may use the inshore traffic zone.
What is traffic separation zone?
separation zone or line: a zone or line separating traffic lanes in which ships are proceeding in opposite or nearly opposite directions; or separating a traffic lane from the adjacent sea area; or separating traffic lanes designated for particular classes of ship proceeding in the same direction.
What is precautionary area in TSS?
Some TSS areas comprise precautionary areas (Figure 1b). Precautionary area is defined as 'a routing measure comprising an area within defined limits where ships must navigate with particular caution and within which the direction of traffic flow may be recommended' (IMO 1985).
What rule is traffic separation scheme?
Rule 10: Traffic Separation Schemes. (c) A vessel shall, so far as practicable, avoid crossing traffic lanes but if obliged to do so shall cross on a heading as nearly as practicable at right angles to the general direction of traffic flow.
What are the 3 types of vessels allowed in the Inshore traffic Zone?
d. (i) A vessel shall not use all inshore traffic zone when she can safely use the appropriate traffic lane within the adjacent traffic separation scheme. However, vessels of less than 20 m in length, sailing vessels, and vessels engaged in fishing may use tile inshore traffic zone.
What is Rule number 6 in Colreg?
Every vessel shall at all times proceed at a safe speed so that she can take proper and effective action to avoid collision and be stopped within a distance appropriate to the prevailing circumstances and conditions.
Is TSS mandatory?
Along with the regulation of traffic/traffic management in such areas, TSS is imperative in the prevention of accidents (that have frequently happened in the past) among the number of vessels plying through any such given area. The IMO has listed over 200 such TSSs, the absence of which will lead to utter chaos!
What are the 4 stages of voyage planning?
There are four stages of Voyage Planning that are, Appraisal, Planning, Execution and Monitoring that logically follow each other. An appraisal of all information available must be made before detailed plans can be drawn up and a plan must be in existence before tactics for its execution can be decided upon.
Does the TSS give you the right of way?
Sailing vessels crossing a TSS are required to not hinder shipping within a TSS and so the usual rules under COLREGS are different although a TSS does not give any other 'rights of way' to any other vessel.
What is Rule No 10 in Colreg?
Rule 10 states that ships crossing traffic lanes are required to do so "as nearly as practicable at right angles to the general direction of traffic flow." This reduces confusion to other ships as to the crossing vessel's intentions and course and at the same time enables that vessel to cross the lane as quickly as ...
Can you anchor in a traffic separation scheme?
(f) A vessel navigating in areas near the terminations of traffic separation schemes shall do so with particular caution. (g) A vessel shall so far as practicable avoid anchoring in a traffic separation scheme or in areas near its terminations.
How do you cross in a traffic separation scheme?
In accordance with Rule 10 (c) (Traffic separation schemes), vessel shall so far as practicable avoid crossing traffic lanes, but if obliged to do so shall cross on a heading as nearly as practicable at right angles to the general direction of traffic flow.
What is the purpose of traffic separation scheme?
A Traffic Separation Scheme (TSS) is created to regulate the flow of traffic of vessels in congested waters.
What is the separation zone Indian Ocean?
Malacca Strait, Singapore Strait and Sumatra On the Eastern borders of the Indian Ocean are the Malacca Strait, Singapore Strait and the waters around the Indonesian island of Sumatra.
What is separation scheme?
A Separation Scheme tells you (or your lab partner) where your product and any by-products are at any point during the isolation of your final product from a chemical reaction.
When joining or leaving a traffic separation zone from the side what must you do?
(ii) so far as practicable keep clear of a traffic separation line or separation zone; (iii) normally join or leave a traffic lane at the termination of the lane, but when joining or leaving from either side shall do so at as small an angle to the general direction of traffic flow as practicable.
DIELECTRIC STRENGTH
A measure of the ability of an insulating material to withstand electric stress (voltage) without failure. Fluids with high dielectric strength (usually expressed in volts or kilovolts) are good electrical insulators. (ASTM Designation D 877.)
COPPER STRIP CORROSION
A qualitative measure of the tendency of a petroleum product to corrode pure copper.
SALINITY
A measure of the concentration of dissolved mineral substances in water.
IMMISCIBLE
Incapable of being mixed without separation of phases. Water and petroleum oil are immiscible under most conditions, although they can be made miscible with the addition of an emulsifier.
INTERFACIAL TENSION (IFT)
The energy per unit area present at the boundary of two immiscible liquids. It is usually expressed in dynes/cm (ASTM Designation D 971.)
HIGH
An area of high pressure. Since a high is, on a synoptic chart, always associated with anticyclonic circulation, the term is used interchangeably with ANTICYCLONE
POISE
A measure of viscosity (absolute viscosity) numerically equal to the force required to move a plane surface of one square centimeter per second when the surfaces are separated by a layer of fluid one centimeter in thickness.
How many traffic lanes are there in a TSS?
Within a TSS there is normally at least one traffic-lane in each main-direction, turning-points, deep-water lanes and separation zones between the main traffic lanes. Most TSS schemes include 'inshore traffic zones' between the traffic-lanes and the coast.
What is the Dover Strait?
The Dover Strait/Détroit du Pas de Calais was the first International Maritime Organisation (IMO) approved traffic separation scheme in the world in 1967. Other TSS areas can be found in the Mediterranean Sea, western side of the Atlantic Ocean and the Pacific .
What is a TSS chart?
Example of a TSS on a chart. A traffic separation scheme or TSS is a maritime traffic-management route-system ruled by the International Maritime Organization or IMO. The traffic-lanes (or clearways) indicate the general direction of the ships in that zone; ships navigating within a TSS all sail in the same direction or they cross ...
Where are TSSs used?
TSSs are used in locations where there is a lot of traffic (busy shipping areas) where not regulating the traffic would lead to more accidents. In Europe, many TSS areas are found around the Southern part of the North Sea including the English Channel.
