Shoalbuster Siskin

The Shoalbuster “Siskin” has proven herself as a real allrounder. This workboat and her crew are real workaholics and have done a lot of oil & gas and dredging projects.
Shallow allround

Shoalbuster Siskin

The shoalbuster Siskin is the second vessel in our fleet that we took over from Damen. She is a vessel with 40-ton bollard pull but still remains a good draft to operate in the shallow waters.

The vessel has proven herself over the years to be an excellent working vessel in oil & gas projects as well dredging projects. Due to her size, the Siskin is very fuel efficient and extremely qualified for shallow water operations. With her accommodation up to 7 persons in total, there are not many jobs where this vessel is not suitable for in her segment.

The crew and this powerful lady have done lots of projects which make her an ideal workboat for services like anchor handling, towing, dredging support, offshore wind support, and even diving support.
