(D) 22 deg. 25.722’N / 113 deg. 55.288’E
The works will be carried out by a derrick barge. One crane boat and one tugboat will provide assistance.
A working area of approximately 15 metres around the derrick barge will be established. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the barge.
A silt curtain, extending from the sea surface to the seabed, will be established within the works area. The silt curtain is a large piece of netting used to contain mud and sediments. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the extent of the silt curtain.
The hours of work will be from 0700 to 1900 hours. No works will be carried out on Sundays and public holidays. Vessels employed for the works will stay in the works area outside the hours of work.
Diving operations will be carried out from time to time during the hours of work.
Vessels engaged in the operations will display signals as prescribed in international and local regulations.
Vessels navigating in the vicinity should proceed with caution and keep clear of the works area at slow speed, bearing in mind there are divers working in the works area.

Amended Implementing Instructions
Friday, January 11, 2019, Cannakale Strait, Turkey
Waiting times of vessels anchored in the north-south entrances of the Canakkale Strait have increased due to the dangerous cargo-carrier traffic that has recently increased above forecast. An arrangement is necessary to reduce the waiting times of anchored ships without compromising the priority of ensuring safe passage.
The Implementing Instructions titled Contracted and Scheduled LNG Vessels and LPG Vessels article 8, paragraph two, have been amended as follows:
LPG Carriers:
a) LPG carriers with LOA of 150 meters and over complete their transit through the Bosporus Strait with assistance of pilots, escorted tug escorts during daytime; LPG carriers carrying LPG with a LOA of 150 meters and over which are due transit through the Canakkale Strait complete their transit with assistance of pilots, escorted by tugboats during daytime; LPG carriers with LOA of 150-200 meters which are not carrying LPG complete their transit during day/night with pilot assistance.
b) In relation to vessels which are subject to tug escorts; LPG carriers with LOA of 150 meters and over should complete their Bosporus transit passage accompanied by tug escort/s with a bollard pull of minimum 60 tons, LPG carriers with LOA of 200 meters and over should complete their passage accompanied by tug escort/s with a bollard pull of minimum 90 tons.
c) The number of tug escorts and their bollard pulls could be increased if necessary, taking into account the weather and sea conditions.
