Tymor Marine Delivers Industry’s First Remotely Executed Vessel Deadweight Audit
The maritime technology company successfully completed a remote deadweight audit for a semisubmersible oil and gas drilling rig. Believed to be the first of its kind, the remote survey was developed in response to travel and social-distancing restrictions imposed during the COVID-19 pandemic.
Aberdeen-based maritime technology company Tymor Marine has successfully completed a remote deadweight audit for a semisubmersible oil and gas drilling rig in Norway. Believed to be the first of its kind, the remote survey was developed by Tymor in response to travel and social-distancing restrictions imposed during the COVID-19 pandemic. Completing the audit remotely enabled the rig to comply with its statutory obligations on schedule and return to service without delay.
“Conducting the deadweight audit remotely, during the COVID-19 pandemic, allowed our client to meet their obligations, continue with scheduled activity, and avoid any unplanned downtime,” said Kevin Moran, managing director at Tymor. “Despite extensive global travel and social-distancing restrictions, plus our remoteness from the worksite, we were able to use the recorded data, produce calculations, and have these accepted by the authorities. Importantly, we also built a digital record of information along the way that can itself be audited or referred to in future work.”
Deadweight surveys on drilling vessels are required every 5 years, or after major changes, and are normally performed by a team of auditors conducting onboard inspections. The surveys are used to determine the weight and distribution of a vessel’s variable load, which includes the crew and their effects, temporary equipment, cargo, fuel, and water. This allows the lightweight (net structural and fixed weight of the vessel) to be determined by comparing the deadweight calculation with the draught measurement (water displacement). Any change in the lightweight reflects a change in the structure of the vessel, which must be approved by the vessel’s own flag state maritime authority.
Following close collaboration with the client, the maritime authority, and the industry regulator, Tymor developed a new set of remote procedures, which were approved in advance of the survey. Having established these new standards, they will now be available for similar audits in future.
“Due to the success of this project we plan to investigate further opportunities to provide remote survey solutions to our clients,” Moran said. “With partner collaboration, much of this work can also be carried out while the vessel is still in service or in transit, enabling even greater efficiency.”
Preparatory survey work began while the rig was still operational offshore and continued during its transit to a Norwegian shipyard for scheduled work. Under guidance from Tymor, the rig crew provided the required data, plus photographic and video evidence, which was shared between the partners along with the analysis results and quality checks. The maritime authority attended virtual meetings and critical stages of the survey remotely, via video link. Once the rig was ready to leave the shipyard, the final draught measurements were recorded and witnessed by the rig management, Tymor Marine, and the maritime authority. The collaborative process resulted in a successful audit and timely certification of the vessel.
