The Norwegian Ocean Industry Authority (Havtil) has conducted an audit of the follow-up by Odfjell Drilling (Odfjell) of the alarm management systems in the drilling cabins on the Deepsea Aberdeen, Deepsea Atlantic, Deepsea Nordkapp, Deepsea Stavanger and Deepsea Yantai facilities.
Background
Alarms from the control system are often the first alert that operators receive of conditions that are about to become uncontrollable. In recent years, Havtil has conducted audits of alarm systems in central control rooms on drilling facilities, onshore facilities and production facilities. These audits have revealed several weaknesses in the alarm systems. We have also encountered challenges with high alarm rates and many standing alarms. This indicates that there may be deficiencies in the follow-up of the systems, as well as how high alarm rates and many standing alarms impact on the working conditions of operators in the drilling cabin.
Objective
The objective of the audit was to verify that the drilling contractors are following up the alarm systems in accordance with the applicable regulations and internal requirements.
Result
We identified two non-conformities during the audit. These concerned:
Follow-up of the alarm systems
Analyses in drilling cabin
The non-conformity applies to Deepsea Nordkapp and Deepsea Yantai.
What happens now?
Odfjell has been given a deadline of 31 January to report on how the non-conformities will be addressed.
