Integrated Mast Module (IMM) installed on Oceangoing Patrol Vessel (OPV) Holland for the Royal Netherlands Navy.
After successful platform trials, handover to the Netherlands Defence Materiel Organisation(DMO) and initial tests by the Royal Netherlands Navy the first OPV Holland returned to DAMEN Schelde Naval Shipbuilding in Vlissingen for the installation of the Integrated Mast Module (IMM).

The installation was successfully completed in the past weeks and the ship integration tests are presently in progress. The installation of the Integrated Mast Module is the last major step before the ship will be transferred to the Royal Netherlands Navy.
The innovative and state of the art IMM was developed by Thales Nederland whereas the mast’s structural design and construction was carried out by the Naval Maintenance Establishment in Den Helder. After an extensive testing period of six months, which took place in Hengelo, the IMM was transported by ship to DAMEN Schelde Naval Shipbuilding in Vlissingen for installation.
The IMM, type I-400, is equipped with, among other things, ‘high definition‘ and infrared cameras, air and surface surveillance and tracking radars, as well as an extensive integrated communication system including Satellite Communications. With the IMM-400 the OPV’s of the Holland class are able to effectively conduct Maritime Security and Safety Operations as well as traditional low end naval tasks. This includes operations with the organic Helicopter (NH-90) and two organic Fast Raiding, Interception and Special Forces Craft (FRISC) as well as other ships, aircraft, helicopters and interceptors.
After transfer of the ship to the Royal Netherlands Navy an extensive test & trial program is foreseen that will be conducted by the Netherlands DMO organisation and Royal Netherlands Navy in cooperation with Thales Nederland. Therefore, for the larger part of a year the Holland’s crew, led by Commander Chris van den Berg, will be involved in testing all the mast’s systems. According to DMO’s project leader, Rob Zuiddam.
The Holland is the first ship in the Holland class, a series of four Oceangoing Patrol Vessels (OPV) for the Royal Netherlands Navy. These 108-meter long, flexibly deployable patrol ships, with a crew of 50, will make a significant contribution to international law enforcement and security (Maritime Security Operations).
The first two patrol vessels, "Holland" and "’Zeeland" have been built at the shipyard of Damen Schelde Naval Shipbuilding in Vlissingen, with a number of sections being supplied by the Damen shipyard in Galati. The Holland, which was christened on February 2, 2010 by Her Majesty Queen Beatrix of the Netherlands, is expected to formally be commissioned by mid 2012.
The third and fourth vessels, "Friesland" and "Groningen" are built at the Damen shipyard in Galati under the supervision of Damen Schelde Naval Shipbuilding. Partial SAT for the "Friesland" have been successfully completed last September. Presently she is at the Damen Schelde Naval Shipbuilding yard for final outfitting of certain systems and components.
DAMEN SCHELDE NAVAL SHIPBUILDING:
The Damen Shipyards Group offers a complete range of naval and patrol vessels ranging from 7 to over 200 meters.
Part of this portfolio are the Damen Schelde Naval Shipbuilding (DSNS) naval combatants and auxiliaries, embodied by the SIGMA and ENFORCER series.
At present DSNS also has under construction for the Royal Netherlands Navy: a Joint Logistic Support Ship (JSS), the largest military vessel built by DSNS so far. For the Royal Moroccan Navy DSNS has two SIGMA frigates under construction, the first SIGMA frigate was transferred to the Royal Moroccan Navy on 10 September 2011.

Integrated Mast passes Factory Acceptance Test with Flying Colours
The first Integrated Mast IM400 has successfully passed the Factory Acceptance Test. The FAT was attended by a delegation from the Netherland’s Defence Materiel Organisation and the Royal Netherlands Navy.
Since the IM400 consists of various subsystems, the actual FAT comprised several tests. After the successful tests the contract partner accepted the first Integrated Mast.
Thales Nederland’s CEO Gerben Edelijn says: “this FAT proves that we are capable of designing, engineering and building a completely new concept in naval sensor and communication technology in a relatively very short time, which once more demonstrates our leading position in this field.”
Following the FAT, the IM400 was shipped to Damen Schelde Naval Shipbuilding and successfully installed on the first patrol vessel “Holland”.
The second IM400 is presently being built by Thales in Hengelo. It will be installed on the second Patrol Ship “Zeeland” early 2013.
About the Integrated Mast
The integrated mast is a completely different design approach from the traditional sensor layout on board of naval vessels. One central mast structure houses the radar, optronic, and communication sensors and antennas as well as all cabinets and peripherals. The advantages of this sensor concept are huge: better operational performance, higher operational availability, reduced ship-building time, reduced maintenance requirements and enormous savings in below-deck space.
About the sensors
SeaMaster 400 is a non-rotating S-band radar with four faces for air and surface surveillance. It is derived from the proven SMART and APAR radar systems. SM400’s unique concept of multibeam volume search with four active scanning faces ensures the simultaneous performance of all operational tasks at a high update rate and very low false alarm rate. SM400 also provides helicopter direction and approach capabilities and has three fire control channels. The system’s high number of parallel transmit and receive channels provide a high degree of redundancy.
Seawatcher is a four face non-rotating active phased array X-band radar for naval surface surveillance. The high resolution system automatically detects and tracks asymmetric threats and very small objects such as mines, periscopes. Seawatcher can also be used for helicopter guidance.
Gatekeeper is a 360° panoramic electro-optical surveillance and alerter system based on IR/TV technology. Designed to counter emerging asymmetric threats down to small boats and swimmers, Gatekeeper increases short-range situational awareness in littoral environments.
ICAS, the Integrated Communication Antenna System facilitates the use of standard VHF/UHF communications equipment, is fitted with Link 16 integration, provides excellent transmit/receive isolation, offers estate for auxiliary antennas such as GSM/GPS and is designed for future growth.
NR IFF, the non-rotating Identification Friend or Foe, uses a cylindrical array fitted to the top of the structure. It is designed to operate with standard interrogator/transponder systems. It is optimized for operation with a non-rotating primary radar and offers accuracy commensurate with Mode 5/S.
Thales is a global technology leader for the Defence & Security and the Aerospace & Transport markets. In 2010, the company generated revenues of €13.1 billion with 68,000 employees in 50 countries. With its 22,500 engineers and researchers, Thales has a unique capability to design, develop and deploy equipment, systems and services that meet the most complex security requirements. Thales has an exceptional international footprint, with operations around the world working with customers as local partners. www.thalesgroup.com
