The ships are both mothervessels for standard STS operations, however due to various reasons it was necessary to perform an STS operation between these two large vessels. This was the largest STS operation ever performed in Danish waters and required exceptional cooperation between agents, pilots, towage company and STS provider. The vessels had to lie idle for a few days awaiting a proper weather window. This materialized on the 09 of October 2009 in the afternoon.

All good forces were put together and the operation was performed smoothly and safely as always, thanks to professional cooperation between Maersk Broker Agency and all the involved parties.

The reasons for performing STS operations are many, but generally this is performed on vessels which have too deep a draught to pass through the Great Belt. By using the VLCC´s for the long haulages rather than sailing with the smaller vessels, we reduce the fuel consumption per ton transported thus reducing the carbon footprint for the cargo.

While at anchorage the vessels requires a long range of services, amongst others crew changes, provisions, diving assistance surveys repairs etc.
