Since its launch in December 2015, DNV GL’s certification scheme for offshore gangways DNVGL-ST-0358 - Certification of offshore gangways for personnel transfer has proven to be a very well received service by the industry. The “Walk2work” class notation supporting this certification standard is introduced and will be published January 2017.
With a rapid expanding offshore wind energy sector and growing numbers of unmanned wellhead platforms, the call for flexible walk-to-work solutions is increasing. These operations include high frequency personnel transfer operations often performed under challenging environmental conditions with high wind speeds and harsh sea conditions.
Class notation “Walk2work” is now launched to further secure transparency and predictability in the marine-offshore industry. Walk2work-notation enables ship- and rig owners to document capability and integrity of offshore gangway systems installed on board.
Certification standard DNVGL-ST-0358’s design and safety principles have been successfully implemented into the fully certified modular, active motion compensated gangway from SMST.
‘Our continued collaboration with DNV GL for certification of our cranes and more recently, our offshore gangways, has proven fruitful yet again. The next step would be obtaining a DNV GL Type Approval for both our medium – TAB 3M – and extra-large - TAB 2XL – offshore gangways’, says Pieter de Bos, Project manager at SMST.
DNV GL has been working closely with Barge Master into defining the certification frame for one of their newest and innovative concept: an offshore gangway with secondary offshore crane function.
‘I am very happy about the collaboration with DNV GL, and extremely proud the Barge Master Gangway is the first to receive the DNV GL approval in principle’, says Jorrit van Dommelen, R&D engineer at Barge Master.
‘We are happy to see that our efforts in 2015 to issue the new standard have been rewarded in 2016 with a lot of positive feedback. Our customers have been working hard and with each new design we see the industry benchmark set higher and higher. Well done and we are proud to support the effort of improving safety in offshore personnel transfers’, says Aldo Matteucci Head of DNV GL’s Lifting Appliances section.
Continuous development and improvement of rules and standards are considered as an essential activity in DNV GL. An improved scheme for qualification of control system performance of offshore gangways will be introduced shortly. Main focus of this extended system certification will be software integrity assurance based on simulator testing.
