How we towed a massive 40,000-ton vessel through a mountain.

When towing a vessel, there are several calculations that can be performed to ensure the safety and efficiency of the towing operation. Here are three simple but useful calculations:

1. Towing speed calculation: The towing speed is the speed at which the towing vessel can safely tow the disabled vessel without causing damage to either vessel or the towline. The towing speed can be calculated using the following formula:

Towing Speed = √(LBP x 0.0134)

Where LBP is the length between perpendiculars of the towing vessel in feet. This formula provides a safe towing speed in knots for calm water conditions. However, the towing speed should be adjusted based on the sea state, wind, and other environmental factors.

2. Towing force calculation: The towing force is the force required to move the disabled vessel through the water. The towing force can be calculated using the following formula:

Towing Force = (Δ x Ct x V²) / 2

Where Δ is the displacement of the disabled vessel in tons, Ct is the towing coefficient (which depends on the hull shape and condition of the disabled vessel), and V is the towing speed in knots. This formula provides an estimate of the towing force required to move the disabled vessel at a given speed. However, the actual towing force may vary depending on various factors, such as the sea state, wind, and current.

3. Towline length calculation: The towline length is the distance between the towing vessel and the disabled vessel. The towline length should be long enough to provide adequate maneuverability and shock absorption, but not so long that it causes excessive sway or yaw. The towline length can be calculated using the following formula:

Towline Length = 2 x √(LBP x D)

Where LBP is the length between perpendiculars of the towing vessel in feet, and D is the displacement of the disabled vessel in tons. This formula provides an estimate of the minimum towline length required for safe towing. However, the actual towline length may need to be adjusted based on various factors, such as the sea state, wind, and current.

In summary, these three simple but useful calculations can help ensure the safety and efficiency of a towing operation. By calculating the towing speed, towing force, and towline length, the towing crew can make informed decisions and adjustments to ensure a successful towing operation.
