In the face of intense competition in the oil and gas industry, several companies are vying for new business development opportunities. It might seem that there's little left to innovate in this field.

Taking the lead are Dutch shipbuilders Damen. In 2016, their renowned engineers announced a new conceptual project called the Damen Decommissioning Series.

The project entails a series of specialized maritime vessels capable of decommissioning over half of the stationary marine structures located in the North Sea. Designed for versatility, these vessels are tailored to focus on three core sectors of the oil and gas industry: decommissioning of old marine structures, removal of topside platforms, and cleansing and removal of underwater structures.

The most notable feature of the new single-hull vessel is its split stern, crucial for marine object extraction operations. Such a design allows for the dismantling of stationary platforms weighing up to 1,600 tons. However, to maximize adaptability, the conceptual design incorporates modular enhancements. These will enable the vessel to perform other tasks during periods of contract inactivity. For example, modular additions include the temporary installation of a crane, a helipad, or accommodation modules for personnel.

A similar transformation outcome could facilitate the transportation or installation of sections in the offshore wind energy sector.

The decommissioning concept in the offshore or transportation sector is closely aligned with Damen's current endeavors, and therefore, they intend to advance this project to full implementation.
