Offshore Walk To Work Mobilisation
Customer Challenge
|
Client had a requirement of Walk to Work system to be mobilised for a summer maintenance campaign. Because of the size of vessel relative to the access position on the platform, the walk to work gangway had to be installed as high up the vessel as possible.
This presented a significant challenge for structural design and integration since the vessel scantlings at the required deck were comparatively light and there was a crane pedestal immediately in way of where the support structure was required to go. An access stair tower also had to be designed and fitted to the upper deck. |

Key Skills Exhibited
|
Candidate vessel required an on-site survey to determine its suitability for receiving a walk to work bridge. Experience in vessel structural behaviour and quasi-static analysis was used to develop a beam-element model of the required support structure and stair tower. Analysis results were used to develop first principles engineering calculations and to check the vessel structural response under a variety of load cases.
Leadership and strong decision-making capabilities were key to determining a suitable solution while close liaison with Class Society smoothed the approvals process in this fast-track project. |
