Damen’s shallow-draft Shoalbuster ready for delivery


(GORINCHEM, Netherlands) — Damen’s new Ultra Shallow Shoalbuster 3815 SD has successfully completed sea trials and bollard pull testing. The newly designed vessel achieved 18.6 tonnes of bollard pull, while still being able to operate in extreme shallow waters. Despite this show of power, noise levels inside all the cabins did not exceed 53dB.

Damen developed the design of the new Shoalbuster 3815 SD after extensive dialogue with numerous workboat operators from the oil and gas, and dredging industries, in addition to end clients who charter such vessels. This highlighted the need for a truly fit-for-purpose vessel capable of working in ultra-shallow waters.

“There are several projects in the world that operate in ultra-shallow working areas – in the Arabian Gulf and the Caspian Sea in particular,” said Jeroen van Woerkum, commercial manager at Damen Shipyards Hardinxveld. “We designed this vessel to provide real added value to these projects.”

The results from the sea trials and bollard testing of the Shoalbuster 3815 SD last week in the Middle East prove just how useful the vessel will be. The installed power of 1,540 bhp directed through four 1,000-mm aft propellers yielded 18.6 tonnes of bollard pull. The vessel has a working deck space of 185 cubic meters and is equipped with two bow thrusters to provide manoeuvrability when needed.

Perhaps the most notable outcome of the sea trials, however, is the ultra-shallow draught specifications. The Shoalbuster 3815 SD can work in a water depth with a minimum of 120 cm (3.9 feet).

As well as operational prowess, Damen has paid particular attention to comfort on board. The noise levels in the accommodation area are a maximum of 53dB.

The 250-dwt vessel’s standard accommodation for 11 people is in accordance with MLC regulations. Additional accommodation for total of 17 people is optional.

With the sea trials successfully completed, the Shoalbuster 3815 SD is going to be available for delivery and operation by Jan. 1, 2020.
