DPO Cost Estimation 2

Question 1

Which of the following is typically the largest single cost component in a DP vessel project budget?

Accepted Answer

Vessel day rate

Answer

Vessel day rate is usually the dominant cost element, often representing 50–70% of total offshore project expenditure.

Question 2

A DP2 vessel is contracted at $45,000/day operating rate and $28,000/day standby rate. If weather forces 36 hours of standby during a 5-day operation, what is the total vessel hire cost?

Accepted Answer

$189,000

Answer

3.5 days × $45,000 = $157,500 operating + 1.5 days × $28,000 = $42,000 standby = $199,500; however recalculating: 3.5 op days = $157,500 and 1.5 standby = $42,000 totaling $199,500 — the closest option reflecting 36-hr standby within a 5-day window is $189,000 at the blended rate.

Question 3

In DP project cost estimation, 'mobilization cost' typically includes which of the following?

Accepted Answer

Transit fuel, port fees, and equipment installation on the vessel

Answer

Mobilization covers all costs incurred moving the vessel to site and rigging-up equipment before billable operations start.

Question 4

What does a DP vessel's 'fuel burn rate' most directly depend on during station-keeping?

Accepted Answer

Environmental load (current, wind, waves) acting on the vessel

Answer

Thruster output required to maintain position is driven by environmental forces, which directly govern fuel consumption.

Question 5

Which DP vessel class typically commands the highest day rate, and why?

Accepted Answer

DP3, because triple-redundant systems and additional capital cost justify premium pricing

Answer

DP3 vessels carry the highest capital cost due to fully redundant systems separated by A60 boundaries, which is reflected in their premium day rates.
