Load Line Survey

Question 1

State the main purpose of the Load Line Survey

Answer 1

• Ensure all equipment that unships water is in good condition
  (Scuppers, Freeing Ports, Overboard Discharges, Drain Valaves)
• Ensure the ship is not loaded deeper than is safe, gudied by laod lines.

+ That the ship has enough freeboard and reserve bouyancy to stay stable and seaworthy in all conditions

Question 2

Explain the importance of EACH of the following with refrence to the purpose of the Load Line Survey
Bilge System

Answer 2

1) Removes water entering the ship through leaks, and other means such as flooding.
2) Also prevents the accumulation of water in machinery spaces.
+ If the bilge system didnt do these things may occur which would affect the Load Line Survey, such as
- Increase Weight
- Reduce Freeboard
- Submerg Load line Marks
- Breach Load Line Regulations
- Affects Stability, Potentially causing List or trim
3) During the survey, Bilge Pumps, Valves & Alarms are checked to ensure they are efficient and reliable.

Question 3

Explain the importance of EACH of the following with refrence to the purpose of the Load Line Survey
Ballast System

Answer 3

1) Maintains correct traim and stability by shifting or adjusting water ballast.
2) Helps keep the ship upright and waithin the approved Loading Conditions (Load Lines).
+ During the survey, checks ensure
- Ballast Tanks
- Valves
- Pipelines
+ are in good condition and that the system can operate effecitvley when needed

Question 4

Describe the inspection required of a weather deck water-tight door to ensure compliance with load line survey

Answer 4

1) - Structure - Check door/frame for corrosion, cracks or distortion.
2) - Seals - Ensure gaskets are intact, clean and undamaged.
3) - Closing Gear - Operate dogs/handles for full, uniform compression.
4) - Hinges - Confirm free, smooth movement; lubricate if needed.
5) - Hose Test (Tightness) Verification - Witness or review records of a minimum 15 minute hose test at the required pressure (as per SOLAS/Load Line Rules).

+ Confirm ID plates, instructions legibale and survey records complete.

Question 5

with refenece to lubricating oil or fuel oil tanks that have ventilators on the main weather deck
Explain the purpose of the ventilation

Answer 5

• Allows tanks to safely breathe when oil expands/contacts due to temperature changes.
• Prevents prssure or vacum build-up, avoiding structural damage or leaks.

Question 6

with refenece to lubricating oil or fuel oil tanks that have ventilators on the main weather deck
Explain how ingress of sea water in bad weather is prevented

Answer 6

• Vent heads are fitted with ball floats or weathertight cowl heads that seal when submerged.
• Air pipes have goosenecks raised above deck prevent green seas entering.

Question 7

with refenece to lubricating oil or fuel oil tanks that have ventilators on the main weather deck
Explain how the risk of fire entering the ventilator is reduced

Answer 7

• Vent heads fitted with flame screens (usually fine copper gauze)
• These stop flames/sparks from igniting flammable vapours inside the tank.

Question 8

with refenece to lubricating oil or fuel oil tanks that have ventilators on the main weather deck
Explain how the risk of pollution is prevented

Answer 8

• Goose neck or crowl prevents liquid oil from sloshing out in rough seas.
• Ball float valves close if the tank overfills or ship heels, stopping oil escaping.

Question 9

with reference to load lines and associated surveys
State the name given between the dECK line and ⊘
E.G
DECK LINE
-
⊘

Answer 9

Freeboard

Question 10

State the terms associated with TF, F, T, S, W, WNA

Answer 10

TF - Tropical Fresh
F - Fresh
T - Tropical
S - Summer
W - Winter
WNA - Winter North Atlantic

Question 11

Outlie TWO non - confomities that may be found during a Load Line Survey with regard to each of the follwoing
The Ships Structure

Answer 11

• Corrosion/wastage of deck plating or sheer strake reducing strength
• Cracks or deformation in main deck beams or frames

Question 12

Outlie TWO non - confomities that may be found during a Load Line Survey with regard to each of the follwoing
Watertight Intergrity

Answer 12

• Damaged/missing gaskets on watertight doors or hatch covers
• Vent heads with corroded or jammed ball floats that wont close

Question 13

Outlie TWO non - confomities that may be found during a Load Line Survey with regard to each of the follwoing
Stability

Answer 13

• Load line marks missing, incorrect or painted over
• Stability booklet not updated after structural changes or repairs
