Offshore Solutions B.V. (OSBV), the joint venture between AMEC and Cofely Nederland N.V., has launched a free standing Offshore Access System (OAS) designed to significantly reduce installation time.

OSBV has worked with Lowestoft-based, AKD Engineering to convert an existing OAS into a free standing skid mounted unit. The new design will allow quayside installation to be completed in a day and eliminate the need for structural modifications to the vessel to accommodate the pedestal both above and below the deck.


The 80m2 skid-mounted Lloyds-approved unit will reduce the footprint on the vessel leaving more deck space free for storage and workshop facilities.

The free standing unit is pre-commissioned and once installed on a suitable vessel with class two dynamic positioning capability*, it is ready for immediate operation, making it extremely suitable and more cost effective for short term hires.

Since operations began, OSBV has successfully achieved more than 6,500 operational connections and safely transferred in excess of 85,000 personnel without any lost time incidents (LTIs).

OSBV’s managing director, Lindsay Young said: “We are delighted to have launched this new concept, which will offer both time and cost reductions for our customers. In response to market demand, we have recognised a need to effectively reduce customers’ installation time, which will be particularly beneficial for short-term contracts.

“Our OAS has a deservedly strong reputation for the safe and efficient transfer of personnel and we look forward to continuing to demonstrate its effectiveness and economic benefits to an ever widening range of customers.”

* Computer-controlled system to automatically maintain a vessel’s position and heading.
