Abstract

Permit-to-work a key factor for ensuring safety deployment and reduction of investment

Introduction

Offhore wind farms in these days are developing fast. More and more offshore wind farms are in installation and in operation and maintenance. In these harsh condition ‘safety comes first’ is one of the most important issues and not just a lip service.
Therefore, the industry requires vigilance in setting standards and tools to enabling safe deployment.


Approach

WindManShip acts with its marine coordination team in the Global Tech 1 project more than one year. With these gained experience and raising questions how to effectively apply resources and processes in a living project, a cloud based software the “OffshoreWindManager” (OWM) was developed and implemented.

It is the only fully complete and integrated software, which will help the market to transport, install and operate safe, efficient for long lasting offshore projects.
From requests to permit demands and -deadlines up to detailed workflows, the ‘OWM’ covers planning and execution phases. It saves demands, permits and approval in a complete log file.




Main body of abstract

Marine Coordination and supervising health and safety issues is required and implemented worldwide. It ensures a long-term operation of the wind turbines while mitigating risks and investments.
Relevant information like certificates, approvals related to personnel and equipment needs to be documented and stored.
Directives must be distributed, safety guidelines to be instructed, hazards to be identified and remedied. Through the permanently change of the harsh environment on site they must be constantly levelled and in occurrence of emergencies the entire documentation needs to be prompt on hand.
Besides people tracking, the coordination of ships and vessels play a decisive role during transport and installation of an offshore wind farm.
Therefore the process of Permit-To-Work (PTW) is a key factor for a fast and safe marine coordination and time critical for the wind farm itself. All offshore assignments need to be checked, approved and documented.
Interfaces between the construction phases should be identified and aligned.
All these workflows require a proper quality in a fast and 24/7 approach. Vessel charters and downtimes for high-qualified personnel have a huge impact in the installation time and overall investments.
Hence it is important to know and to take the processes and requirements for a fast and safe approach in to the field. Teams with experiences and proper education, like nautical science and logistics are required to fulfil this significant task.


Conclusion

In the traditional Permit-to-Work system inherent limitations are evident. Lapses in transparency and any errors in the PTW process incur increase of time and high costs.
Within a project the software makes sure that the HSE maxim “safety first” takes centre stage and the users of the PTW system can check and retain control in every situation. Thanks to the efficient administration, there is more time to concentrate on the relevant facts.


Learning objectives
The presentation puts focus on the requirements for marine coordination and its demands during from transport to maintenance. Issues like permit-to-work, interfaces between the constructions phases and other tools are some of them.
A comparison to paperwork and software solution will be given. Measures of benefits in terms of time and investment as well as significantly increase of safety deployment of all activities on site.
