NORSOK requirements set significantly higher standards of safety redundancy and operational safety than apply to SOLAS-compliant davits.
Many of these features were already standard on Vestdavit systems which had been tailor-made for demanding offshore and naval operators. However Vestdavit wanted to ensure it had a range of NORSOKdavits available and would be able to advise clients on the requirements well ahead of their implementation date.
“We invested significant resources to understand the NORSOK requirements,” explains Bjørnar Dahle, Vestdavit key account manager, “and we built upon our experience with naval and offshore projects. We had a first NORSOK-compliant prototype ready in 2010, well ahead of the market but in line with the planning needs of major offshore developers. We worked closely with DNV throughout and achieving design verification approval this summer was an important milestone. But it is not just about safety and efficiency. We also believed that the lifting capacity would be higher than normal FRC davits, since operators were likely to choose larger boats. This has proven to be the case and we now have FRC/MOB davits and winches with capacity up to 6 tonnes, and with hoisting speeds up to 123 m/min on monohull installations. Our prepared nessenables us now to meet tight deadlines, as the yards and operators finally come to terms with the new requirements.”
Last year Vestdavit was contracted for the first NORSOK-compliant davit for a support vessel, and recently it secured an order for a D-5000 NORSOK davit to handle the FRC on an accommodation platform being built by Cosco, China, for Axis Offshore.
Dahle says that there is now major demand for good advice on the differences between NORSOK and SOLAS standards. “Operators know they will have to make changes, but they are not clear yet on what the changes will be. We have developed data sheets which spell out the requirements and we understand clearly what the consequences of the requirements are for updates and replacement systems. We are ready to advise offshore operators. There will be a scramble for compliant equipment when the rules come in so clarifying now what changes will need to be made will save operators money and possible downtime.”
