Herman Senior acquires new workboat

Dutch marine contractor Herman Senior recently took delivery of a new workboat built locally by Damen Shipyards Hardinxveld.

The 32.8- by 12.5-metre Bella will be used for a range of duties including towing, dredging, salvage operations, windfarm support, and anchor handling. A draught of only 1.85 metres allows the vessel to access restricted areas.

Three Caterpillar C18 engines with a total output of 1,797 kW at 1,800 rpm deliver a bollard pull of 30 tonnes and a speed of 10.8 knots.

Bella was designed in compliance to Bureau Veritas (BV) class rules.

Van Oord christens second LNG-powered dredger in series

Van Oord has formally named Vox Apolonia, the second LNG-powered trailing suction hopper dredger (TSHD) in a series ordered from Keppel Offshore and Marine (Keppel O&M) of Singapore.

As with the other TSHDs in the Van Oord fleet, Vox Apolonia will be used in a range of projects such as coastal protection, port construction, deepening of waterways, and land reclamation.

The BV-classed dredger has a hopper capacity of 10,500 cubic metres and is powered by a dual-fuel propulsion that is also configured to run on LNG. Van Oord designed the vessel in-house in cooperation with Dutch naval architecture firm DEKC Maritime.

Jan De Nul unveils unmanned survey vehicle

The Jan De Nul Group has introduced a new unmanned surface vehicle (USV) to be used for hydrographic surveys in inland waters.

Measuring only two metres long, Vaquita 01 is fitted with multi-beam sonars for seabed scanning, a laser scanner for surface assessments, and four batteries that will allow full-day operations without recharging.

Jan De Nul said the USV can be used in all phases of a dredging project, from the tender phase before the project itself begins to evaluation upon completion of works.

UK’s Briggs Marine orders maintenance support vessel

UK marine contractor Briggs Marine and Environmental Services has awarded Spain’s Freire Shipyard a contract for the design and construction of a new maintenance support vessel.

The vessel will support Briggs’ ongoing contracts for the inspection, servicing, and replacement of navigation marks and heavy inshore moorings, operating as required with an attendant onboard diving team. It will have a length of 40 metres, diesel-electric propulsion, and accommodations for six crewmembers and 10 project personnel.

Delivery is scheduled for 2024.
