WEATHER DOWNTIME
FEATURE SPONSOR
Accounting for weather in marine operations
Weather downtime may be defined as the time when something is not operational or when a planned activity does not occur as a result of unfavourable weather conditions. Excessive weather downtime makes constructing, maintaining and servicing offshore structures challenging and costly for developers and operators.
Although it is impossible to completely eliminate the impact of weather on offshore operations, understanding the likelihood of successful execution provides a means of managing the logistical, safety and financial risks associated with changing environmental conditions.
PLANNING AHEAD
Offshore construction, operation and maintenance activities have timescales looking two, three, perhaps even five years ahead. As such, conventional weather forecasting cannot hope to predict the weather conditions so far into the future. In its place, statistical analysis of past meteorological and oceanographic data is used to give an indication of what conditions might be like over a particular time period for a given location.
Such information allows decision-makers to take account for weather downtime in their schedules, potentially achieving significant cost savings. Where weather risk is passed to the contractor, this information is important for determining fixed delivery costs when tendering.
