A naming ceremony was held recently at Damen Shipyards Hardinxveld, to mark the first of a new model in the Damen Shoalbuster range, an ultra-shallow, Shoalbuster 3514 SD, owned by tug and workboat company, Herman Sr.

The Shoalbuster 3514 SD, named Brutus, is one of the largest and most sophisticated in the range. A substantial and versatile working platform, it measures 35m in length, nearly 14m wide and has a free deck space of 150m2. With a draught of 2.85m at full tank capacity and 2.45m at 50%, the vessel is able to access waters inaccessible to other vessels of a similar size and capability. Four Caterpillar C32 ACERT engines deliver a total of 5,280 bhp to four 1900mm nozzles, an arrangement that contributes significantly to her shallow-water capability. 60t bollard pull enables powerful towage capabilities.

Among the many other roles which the Brutus will be capable of taking on are PLGR operations, ROV surveys and a 600 x 800mm moonpool for multibeam access, mattress installations, UXO clearance, mooring, pushing, dredging support, ocean-going towage and general offshore supply vessel duties. Other features include four-point mooring and an open stern complete with roller for anchor handling. Accommodation comprises 12 cabins for six to seven crew plus 13-14 additional personnel.

Brutus will be deployed primarily for wind farm support and maintenance duties where the shallow draught will allow work near as well as offshore. The DP2 dynamic positioning system including ancillary thrusters will ensure precise position-holding on the open sea as well in the vicinity of turbines and other structures. The open stern will make the vessel suitable for cable-laying operations and a sturdy aft deck HS Marine knuckle boom crane will be capable of lifting a wide assortment of cargo and equipment.

Jack van Dodewaard, for the owners, said: “The Van Dodewaard  family, as Herman Sr BV, are still very happy with the good and long term cooperation with Damen Shipyards. For nearly 75 years, and across three generations, they have been  our vessel supplier and we hope it will last for many more years. The fourth generation of the Van Dodewaards is taking over this year, with Erwin and Chris carrying on with the family business.”

Damen's Jos van Woerkum said: “We are proud to have built our 14th Damen vessel to Herman Sr since we began our mutual cooperation more than 70 years ago in 1947. The Brutus is the first diesel-electric Shoalbuster with hybrid propulsion in the range, with a shallow draught, dynamic positioning 2 and compliant with the latest IMO Tier III requirements following installation of a treatment system to reduce its emissions. These features are in line with current developments within the Damen organisation that aim to make it become the most sustainable shipbuilder in the world. The vessel’s features include a deck load capacity of 10t/m2, a free deck space of 200m2 and is equipped with a heavy deck crane and two powerful winches. With 60t of bollard pull we wish Herman Sr much success with this innovative vessel and look forward to continuing our close relationship into the future.”
