Section 1 Survey of towing

101. Application

The requirements in this Chapter apply to the checking of seaworthiness of barges and tugboats, and to the safety inspection of towing arrangement (hereinafter referred to as the “survey of tow- ing") by Owner's request before cargo transportation.

102. Submission of data

1. The Owner is to submit the application for survey of towing and following data to the Society.

(1) Certificate for surveys of ships or barges

(2) Certificate for bollard pull of tugboats specified in Ch 2. 106

(3) Towing plans including followings

(A) Main information of tugboats and barges

(B) Number of person on board (in case of manned barges)

(C) Service area, towing speed, cargo volume, cargo weight and duration of operation

(D) Calculation results of total resistance of barge

(E) Strength calculation results and plans of towing arrangement

(4) Other data where this Society considers necessary

2. In case of the tugboats and barges holding the certificates of towing approved by the Society al- ready, the data as specified in 1. (1) and (C) and (E) of (3) are to be submitted and the others may be dispensed with.

103. Certificates of barges

1. When a barge which does not classed with the Society is to be surveyed for towing, the applica- tion for survey of the barge is to be made by the Owner before the survey of towing.

2. At the application of 1., the barge is to be surveyed in accordance with the requirements specified in Chapter 2. Section 2 and Rules and Guidance for Classification of Steel Barges. Where barges have undergone the survey to the satisfaction of the Surveyor, the certificate for survey of the barges is issued.

3. The valid term of the certificate is 2 years. Even though it is not suitable for the strength speci-

fied

hull

in Rules and Guidance for Classification of Steel Barges, where the actual condition of

and equipment is deemed in order, valid term of the certificate may be the period within one

year as decided by the Surveyor.

4. For a barge classed with the Society, if requested by the Owner, the certificate for survey of barge may be issued after reviewing the survey reports. In this case, the valid term of the certificate is to be taken as the expiry date of next Special Survey.

104. Survey of towing

1. The survey of towing by tugboats is to be carried out as following:

(1) Checking whether it has undergone Special Survey following the Rules for the Classification of Steel Ships or the Korean Ship Safety Act, and it may keep up the seaworthiness by reviewing the survey reports and etc.

(2) Reviewing the last survey reports for primary members of ship side plating, deck plating and watertight bulkhead, etc above waterline and underwater parts. Where, however, it deemed nec-

essary by the Surveyor, overall inspection of hull may be requested.

(3) Surveying all openings in exposed area and checking the operational performance of all closing appliances.

(4) Surveying actual status of navigation appliances, anchoring and mooring equipment, fire- ex-

tinguishing system, bilge system, overboard discharging

(5) Surveying actual status and operational performance of

valves and etc.

communication equipment, life-saving ap-

pliances and collision prevention measures as specified in Chapter 2 Section 1.

2. The survey of towing by barges is to be carried out as followings:

(1) Checking the valid term of certificate as specified in 103. is effective or it has undergone Special Survey following the Rules for the Classification of Steel Ships, it may keep up the seaworthiness.

(2) Reviewing last survey reports for underwater parts and primary members like as ship side plat- ing above waterline, deck plating and watertight bulkhead. Where, however, it deemed necessary

by the Surveyor, overall inspection for hull may be requested.

(3) Surveying all opening in exposure area, overboard discharging valves and sea suction valves,

and checking the operational performance of all closing appliances. The effectiveness of closing appliances in cargo hatchway is surveyed carefully.

(4) Checking the sealing conditions of all opening in exposure area, overboard discharging valves

and sea suction valves and the securing conditions of ventilator, funnel and etc. after covering with canvas. However, if it is manned barges, minimum necessary entrance, overboard discharg- ing valves and sea suction valves for crew may be provided on board.

(5) For the scuttle without cover fitted at boundary of enclosed area giving access to exposure area or space below freeboard deck, checking whether the sealing measure from sea water is effec- tive, even if the window is broken.

(6) Carrying out sounding for all compartment and checking whether the bilge is fully discharged.

(7) Checking keeping up the proper draft and trim for towing. Adjusting the draft and trim if necessary.

(8) Fixing the rudder at center.

(9) Checking the conditions of necessities like as emergency ration, drinking water and etc. for crew and emergency electric power sources, if it is a manned barge.

(10)Verifying the load line of barge or checking the cargo loading and securing condition on barge.

(11)Surveying actual status and operational performance of life-saving appliances, communication equipment and collision prevention measures specified in Chapter 2 Section 1.

(12)Where the barge operate within smooth water or service area reached in 2 hours, relaxation from requirements specified in (3) to (11) may be accepted.

3. The survey of towing arrangements is to be carried out as following.

(1) Confirming materials and scantling of rope for towing, chain, shackle and etc. written in ar- rangement of towing arrangements and checking the conditions of them.

(2) Surveying actual status of capstan for towing, deltaplate, towing hook, bollard(or bit, fair-leader)

and etc.

(3) Confirming arrangement of towing arrangements. Especially it is deemed that the locations of rope for towing or chain are to be such that there is possibility of indent due to contact with hull components when towed, it is reinforced adequately or proper means to reduce the friction of guide roller to a minimum are provided.

105. Towing Certificates

1. Where the tugboats, barges and towing arrangements have undergone the survey to the satisfaction of the Surveyor, the certificate of towing is to be issued.

2. Towing certificate is restricted to a single voyage and valid term of the certificate is determined by the Surveyor within the voyage period. Even if the certificate is not expired, valid term of the cer- tificate is deemed completed, provided that the voyage is finished.

3. Notwithstanding the requirement in Par 2, the Society may issue the towing certificate with one year validity for tugboats and barges if they are classed with any classification society and in- tended to sail for specific sailing route periodically provided that:

(1) the classification of tugboats and barges is to be maintained.

(2) the Owner is to check the effectiveness of all towing arrangements and it's condition is to be in good order.
