The Neglected "Invisible Bill"

In offshore wind power projects, cable and pipeline sealing is a "small purchase", but it is responsible forBlock salt spray, moisture and fireThe key role. When making purchasing decisions, we often hear such voices: "The traditional blocking is done with hundreds of pieces. The MCT module is several times more expensive. Choose the cheaper one first."

However,Offshore wind has a design life of 25-30 years. SealingNot a one-time consumable, but a long-term asset. Only focus on the initial purchase unit price, while ignoringFull life cycle cost（LCC), often leads to an out-of-control operation and maintenance costs in the later stages of the project.

Traditional fire-resistant mud and sealants perform well in the land environment, but at sea.High salt spray, high humidity, strong vibrationIn the harsh environment, the aging rate is significantly accelerated.

In the key parts of the bulkhead and sea side penetration of the booster station, the traditional plugging materials usually crack, fall off or powder in about 5-10 years, and need to be repaired or replaced.

Many purchasers often only calculate the cost of materials when accounting, but ignore the "comprehensive bill" for offshore operations ":

Data reference:

Taking a conventional booster station bulkhead penetration as an example, the initial investment of traditional plugging is low (about several thousand yuan). If the first repair is made after 5-8 years, the combined cost of a single repair is often several times the initial investment, taking into account material, labor and downtime losses.

Based on a 30-year operating cycle, traditional plugging usually requires 3-4 repairs. If downtime losses are included, the 30-year cumulative cost can reach 3-5 times the initial investment; even if only the repeated input of materials and labor is calculated, the cumulative cost is close to twice the initial cost.

The initial purchase cost of the Tastet MCT wear barrier sealing system is relatively high, but its core logic is to putCost front, in exchange for the late 30 years of "certainty".

This certainty comes from the matching of its design to the material:

Cost inflection point analysis:

In a typical scenario (first repair in years 5-8 of traditional plugging), the total cost of the TasteMCT sealing solution is usually overshot around year 10 and becomes lower than that of the traditional plugging solution. As the operating time lengthens, the cumulative cost gap between the two will become more pronounced.

For heavy asset projects such as offshore wind power with long cycles and high operation and maintenance costs,Full life cycle cost(LCC) isThe core yardstick for measuring cost performance。

When we purchase seals, we may as well ask a few more questions:

1. Can you reduce an expensive window to go to sea?

2. Can loss of downtime due to plugging failure be avoided?

3. Can we reduce the cost of demolition and reconstruction in the later stage of technological transformation?
