Shoalbuster Brutus

Shoalbuster Brutus is de latest addition to the Herman Senior fleet, and is the first DP2 Shoalbuster ever built. She was built at Damen Hardinxveld and is in active service since May 2021.

With 35 metres in length, nearly 14 metres wide and with a free deck space of 150m2, the Shoalbuster 3514 will be a substantial working platform. Her SD (Shallow Draft) notation is derived from her exceptionally shallow draft of 2.70 metres at full tank capacity and just 2.40 metres at 50%. Among the many roles that this first DP2 Shoalbuster is capable of fulfilling are anchor handling, for which she will has an open stern complete with roller, and towage. With 60 tonnes of bollard pull she is a powerful and effective towage asset.

Four Caterpillar C32 ACERT engines deliver a total of 3,879 bkW (5,280 hp) to four 1900mm nozzles, an arrangement that contributes significantly to her shallow-waters capability. The vessel is commonly manned with a crew of five to six mariners, but has an accommodation for up to 21 personnel, allowing her to support projects both ship-based and elsewhere.
