Expeditionary Survey Boat Hydrograaf Named at Damen Shipyard

On February 26, 2021, the naming ceremony and transfer of the Expeditionary Survey Boat Hydrograaf of the Royal Netherlands Navy took place at Damen

On February 26, 2021, the naming ceremony and transfer of the Expeditionary Survey Boat Hydrograaf of the Royal Netherlands Navy took place at Damen Shipyards Den Helde. Due to the coronavirus measures currently in force, the naming ceremony and handover took place in an adjusted manner, whereby the majority of the invitees were present via a livestream. The design and construction of the Hydrograaf was realised in close collaboration between the DMO and DSDH. After construction, the Hydrograaf was allowed to receive a maximum weight of 24 tons, in connection with the maximum permissible loading weight of the Davits hoisting installation on ships such as HNLMS Johan de Witt. At the same time, the ship must reach a speed of at least 20 knots, with very low noise requirements and limited space for recording all hydrographic equipment. After the naming ceremony, the ESB was symbolically handed over by DSDH to Defensie Materieel Organistatie’s Director of Projects, commander Kreiter, followed by a toast to the vessel and her crew. In the coming weeks, the ESB will be prepared for handover to the RNLN, which will start operating the vessel after a work-up period of several weeks.

The ESB will provide up-to-date information about the soil conditions and the situation below the waterline in places where that insight is required. With this information, the Royal Netherlands Navy (RNLSN) supports expeditionary maritime operations and provides an environment in which ships can navigate safely. The main tasks of the ESB are

Gathering environmental information to make decisions about the possibilities of an amphibious operation

Performing hydrographic survey operations in support of emergency relief operations

Supporting with civil hydrographic tasks on the national continental shelf

The sixteen metre long ESB can be deployed from the so-called big decks, such as Zr. Ms. Johan de Witt. The ESB can independently perform hydrographic surveys under tactical conditions at a greater distance from the mother ship. She is a fully fledged platform that is comparable to a hydrographic survey vessel (HOV) and meets the highest survey standards.

The name Hydrograaf has been chosen in honour of the National Inspection Vessel Hydrograaf from 1910. It is also a clear reference to the primary task.
