SW Baltic sea

• 1. Area overview
• 2. Traffic Analysis and risk assessment (preliminary results)
• 3. Possible improvements

Example of maximum ship sizes Tanker shipping:

• L = 250 m B = 44 m T = 15.0 m
• LNG Shipping (Q-Max)
• L = 345 m B = 54 m T = 12m
• Container shipping (e.g. Maren Maersk)
• L = 400m B = 60m T = 14.5m

Port limits:

• Rostock 16.5m planned
• Kiel Canal 10.5m planned
• Luleå 11 m (tanker)
• Kemi 12.5m (?????)
• Klaipėda 12.5 m (tanker, LNG, container)
• Primorsk 15 m (tanker)
• Ust Luga 17.5m (tanker, container)
• Gdańsk 15 m (container, bulk)
• Rostock extension to 16.5m
• Aabenraa 18m (Bulker)

Weather conditions

• Most probable wind directions are

S, SW and W.

• The frequency on the wind force is

as follow:

• 0-3 Bft 41,7 %
• 4-5 Bft 42,3 %
• 6-7 Bft 14,4 %
• 8-12 Bft 1,16 %
• The Average high of the waves is

0,9 m; between 0-1m by 74,9 %.

• By windless or calm sea current of

0,5 kn. In extreme situations (strong E‘ly or W‘ly winds) current

• f 4 kn is possible. [1]

Pleasure crafts

• When pleasure vessels

cross “open water”, they prefer to go in straight lines between the harbours.​

• Pleasure vessels

generally try to avoid sailing in TSS and deep water ways

• Not more then 25 %

have AIS transmitter.

Fishing vessels

• the fishing efforts

variable between the months and the years.

• Main fishing areas

are N‘ly of Ruegen, N’ly of Wismar and the Bay of Kiel.

Commercial shipping

• Around 33 thousand

vessel paused trough Fehrmann Belt and 47 thousand Kadetrinne in 2017

• Vessel are following

recommended routes

• New offshore

structures may increase the risk of collision and groundings

Traffic joinincg here gives relatively high risk

• f collisions

High since most ships pass through here Complex traffic in this area with several crossing traffic streams

Kadetrenden- preliminary results!

Complex traffic in this area with several crossing traffic streams Traffic joinincg here gives relatively high risk

• f collisions

High since most ships pass through here Ships on routes inside ITZ are generally sailing along the same lines in both directions, whereas ships in and entering/exiting TSS Kadetrinne tend to divide into lanes. This leads to relatively fewer head-on collisions.
