Definition

Crane Time Intensity (CTI) is the average number of quay cranes working during a vessel’s cargo-operation window. It is a time-utilization ratio:

O

CTI is a time-utilization metric. It tells you the average number of cranes working over the vessel’s first-to-last-lift window. While not official KPIs, the following two are examples of variants that can be used:

• CTI.productive = only time in productive hoist cycles.

• CTI.billing = the exact rules used by Finance for invoices.

Interpreting CTI

• Higher CTI → more crane time deployed on average; can reflect heavier resourcing or longer overlapping deployment.

• Lower CTI → fewer cranes in use on average; may reflect late starts, early stops, or long gaps.

Relation to Effective Crane Count (ECC)

Refer to KPI ‘Crane Time Intensity (CTI)’ for more information.

• CTI = “On average, how many cranes were working?” → speaks to time deployment

• ECC = “How effectively did we use them?” → actual utilization balance (how evenly cranes shared the work).

Relation to Crane Density

Refer to KPI ‘Crane Density (CD)’ for more information

• Crane Density (CD) = “How many cranes could we use?” → max feasible cranes on the critical path (theoretical potential from stowage and spacing).

• CTI = “On average, how many cranes were working?” → speaks to time deployment

CD governs finish time where it caps true parallelism on the bottleneck. CTI shows how much crane time you actually deployed. It can be high even if the bottleneck (CD) is low.

Bounds and sanity checks

• 0 < CTI ≤ N, where N is the maximum number of cranes that did any work in the window.

• If CTI > planned cranes, check for overlapping reliefs or double-counted hours.

Filter:

The way to differentiate between the various CTIs would be by applying the different filters:

• CTI.productive

  • CHE Type: CHE|@|STS

  • CHE|@|cycle|useful

• CTI.Billing:

  • CHE Type: CHE|@|STS

  • CHE|@|cycle|paid

Carriervisit: ID

Datapoints:

Crane hours deplyed:

• tos|@|carriervisit|@|che|@|assigned|duration|value

Time from first lift to last lift:

• tos|@|carriervisit|@|cargooperations|duration|value

Optional data points

An alternative way to calculate the duration would be to subtract the start from the end; for this case, these would be the data points:

tos|@|carriervisit|@|cargooperations|@|start|time
tos|@|carriervisit|@|cargooperations|@|end|time

Operator:

Sum of all cranes(tos|@|carriervisit|@|che|@|assigned|duration|value) ÷ (tos|@|carriervisit|@|cargooperations|duration|value)

In case it is necessary to obtain the result by using the start and the end of the events, this would be the calculation:

Sum of all cranes(tos|@|carriervisit|@|che|@|assigned|duration|value) ÷ ((tos|@|carriervisit|@|cargooperations|@|end|time) - (tos|@|carriervisit|@|cargooperations|@|start|time))

TIC Description

Required Information

M

• Sum of the total number of hours of all the cranes deployed on the vessel (Gross crane hours)

• the duration between the last lift and the first lift on the vessel (Gross Vessel Working Hours).

Examples - Determining CTI in Different Scenarios:

1. Steady 4-crane operation

• First–last lift = 5.0 hours

• Crane hours = 4 + 4 + 4 + 4 = 16

• CTI = 16 / 5 = 3.2 (on average, 3.2 cranes working)

2. Phased deployment

• First–last lift = 6.0 hours

• Crane hours = 2 + 4 + 6 + 6 = 18

• CTI = 18 / 6 = 3.0

3. Swap with a gap (coverage dips)

• First–last lift = 6.0 hours

• Crane-hours: QC1 6.0, QC2 6.0, QC3 2.0 (fails), QC4 3.5 (arrives after 0.5 h gap)

• Total crane-hours = 17.5 → CTI = 17.5 / 6.0 = 2.92

• Read: Swap + gap reduced average working cranes below 3.

4. Rolling reliefs (no coverage loss)

• First–last lift = 8.0 h

• Crane-hours: QC1 8.0, QC2 8.0, QC3 4.0 (first half), QC4 4.0 (second half)

• Total crane-hours = 24.0 → CTI = 24.0 / 8.0 = 3.0

• Read: Identities changed, but coverage stayed at three on average; CTI unaffected by who the cranes are, only by total hours.
