SHALLOW WATER WORKBOAT WITH 1.2M DRAUGHT COMPLETES TRIALS

Tuesday, December 17, 2019 

Damen Shipyards says that its new Ultra Shallow Shoalbuster 3815 SD design has successfully completed sea trials and bollard pull testing, achieving 18.6t bollard pull while still being able to operate in extreme shallow waters.

Damen developed the design of the new Shoalbuster 3815 SD after extensive dialogue with workboat operators from the oil & 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, 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 in the Middle East prove the validity of the concept. Despite installed power of 1,540 bhp directed through four 1,000mm aft propellers, noise levels inside all cabins did not exceed 53dB. The vessel has a working deck space of 185m2, making it suitable for Single Buoy Mooring (SBM) maintenance works, SBM hose repair and offering sufficient space to add containerised units for diving support works. It 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 120cm.

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

With the sea trials successfully completed, the Shoalbuster 3815 SD will be available for delivery and operation by 1 January 2020.

“We are very excited to show this new vessel to operators needing to carry out hose-, anchor- and buoy- handling and towing and support tasks for the oil & gas industry and the dredging sector in ultra-shallow waters. Our team at Albwardy Damen would be glad to welcome clients on board and showcase this super shallow draught and versatile platform,” said Van Woerkum.
