The MJM Enterprise is a high-performance survey vessel designed to meet the evolving needs of the offshore wind sector.
The MJM Enterprise benefits from various features, including DP0 capability, a large working deck area with space for 2 x 20ft containers, various sensor mounting options, a 1.2m moonpool for through-hull sensor deployment, and comfortable workstation areas.
A passive, anti-roll tank enhances the seakeeping capability, extending available weather windows. A highlight of the vessel is its robust 5T A-Frame with integrated winch, offering 5m internal clearance and flanges on both the outboard and inboard sides, expanding the towing width. With additional booms up top, and coupled with a crane rated to 38T/M, it's perfect for survey, ROV, shallow geotechnical and environmental operations.
The vessel offers a range of benefits more commonly seen on larger vessels, with 20 berths (12 for charterers), a spacious working galley for 8-10 people and a separate lounge area.

The MJM Enterprise is designed for hydrographic, geophysical, and unexploded ordnance (UXO) surveys and offers numerous sensor deployment options.
Its robust 5T A-Frame with integrated winch allows efficient towing and precise deployment of survey equipment. The vessel features a 1.2m moonpool for through-hull sensor installations, providing versatility in equipment options.
Inside, a well-appointed survey station supports both online and offline operations. The dedicated survey desks and remote controls for the A-Frame and winch facilitate seamless management of survey activities. The vessel's passive anti-roll tank minimises roll motion, improving data accuracy and survey efficiency.
The MJM Enterprise is ideally suited for shallow geotechnical campaigns thanks to its comprehensive suite of features designed for efficiency and versatility. The vessel's DP0 dynamic positioning system provides accurate station-keeping, while the robust 5T A-frame and powerful 38T/M crane allow for the precise and safe deployment of various geotechnical equipment such as CPTs and Vibrocorers.
The extensive 75m² working deck offers ample space for equipment and sample storage. Onboard accommodation for up to 20 personnel, including 12 berths for charterers, supports extended geotechnical campaigns.
The MJM Enterprise supports Remotely Operated Vehicle (ROV) survey and inspetion campaigns. The vessel's DP0 dynamic positioning system ensures precise station-keeping while the 5T A-frame and 38T/M crane facilitate the secure launch and recovery of ROVs, even in challenging conditions.
The spacious 75m² working deck with space for 2 x 20ft containers allows for the storage and operation of ROV equipment, and the moonpool allows for simple USBL deployment. With accommodation for up to 12 charterer personnel, the vessel can support extended ROV campaigns.
The vessel is well-equipped for environmental survey and monitoring activities with dedicated survey stations, a capable A-frame, and a seawater wash-down pump. DP0 dynamic positioning allows for accurate station-keeping over environmentally sensitive areas, while the vessel's low emission engines reduce its environmental impact.
The MJM Enterprise is designed to accommodate the needs of diverse survey campaigns with its spacious working areas. The vessel provides 20 berths, including 12 specifically for charterers, ensuring ample accommodation for multi-disciplined campaigns. A generously sized galley, capable of seating 8-10 people, and a separate lounge area offer comfort and convenience for the crew and charterer personnel.
In addition to these amenities, the wheelhouse hosts six dedicated workstations for on-board processing and quality control. A dedicated lab/processing room and a client office further support specialised survey tasks and data analysis, making the MJM Enterprise a highly versatile and functional survey vessel.
