How a Workability Analysis Can Help Offshore Companies Plan Projects

It's perhaps no surprise that offshore companies want to minimize the impact of weather-related disruption to their operations. But just using weather data during project execution misses out on real value it can bring during other project phases. Understanding the weather conditions isn't just crucial for active operations. It also has a vital role in tender responses.

How does a workability analysis work

Say an oil company is going to build a new platform. Companies will be invited to tender for the installation of the platform and, as part of this, the bidding companies will want to develop a picture of the expected weather during the project.

Many delays during the project execution phase will be weather-related. What the companies want to know before tendering is how many days during the project they can expect to be unworkable because the risk of the construction work overrunning is all put on the bidding company. This process is called a workability analysis.

The workability analysis is an overview for a particular period based on operational limits, i.e. the safety limits where they can and cannot work. For example, during a planned five-month construction period, the workability analysis may tell the bidding companies that there will be ten days on average, based on climatology, that they cannot work due to the conditions. This insight means that in their bid to the oil company, they have to go for five months plus ten days. If they risk bidding for just five months and the project lasts for five months and ten days, then these extra ten days will be to the cost of the bidding company. The main thing is that all the risk is for them and they have to include that in their bid, so they can mitigate against it.

Why you need accurate weather data for the workability analysis

Investing in weather data while tendering helps companies to plan effectively, and gives them confidence in the downtime that they can reasonably expect during a project. It reduces the risk of unplanned downtime and helps to maximize efficiency and profitability.

Where companies choose not to use a professional weather service and rely on free online weather data, previous experience or anecdotal data, it can lead them to miscalculate the weather risk: a potentially expensive mistake.

Detailed climatology, supported by experts

For excellent climatology, you need to have at least 25 years of data and a very dense, high-resolution database. MeteoGroup has the highest resolution database available, which is updated every month. Most other companies run at a lower resolution. This means they have locations every 25 kilometers in the North Sea, whereas MeteoGroup has them every 10 to 15 kilometers.

It's also hourly data, where most of the companies rely on three hourly data. As well, the database is automatically updated after every month, where most companies will update their database once a year.

Importantly, the data is also supported by specialist engineers that can advise the customer. It's metocean specialists, people who understand the conditions and the data. There are not many companies that provide a full workability analysis with the highest resolution climatology database available.
