SEA WORKER is a modern jack-up

barge designed to operate in the

challenging offshore waters of

northern Europe. The barge is

particularly suited for deeper wa-

ters and high tidal range sites due

to its 73 m long legs. The offshore

crane on board is a 400T SWL

being capable of installing low to

medium sized foundations and

larger turbines. With air cooled

jacking and auxiliary engines,

SEA WORKER is also able to

operate on sites that dry out at

low tide.

A2SEA has carried out major

upgrade work on the barge since

taking ownership in 2008 with

the state of the art leg penetra-

tion water jetting system proving

extremely effective on sites

with more challenging jacking

conditions.
