Joint Support Ship

According to Kate Tringham, Jane’s Defence Weekly correspondent, the Netherlands Defence Material Organisation (DMO) formally handed over the 28,000-ton Joint Logistic Support Ship (JSS) HNLMS Karel Doorman (A833) to the Royal Netherlands Navy (RNLN) on September 24, 2015. The ceremony marked the successful completion of the majority of the ship’s sea acceptance test programme, a DMO spokesperson said. HNLMS Karel Doorman will now start its work-up trajectory, with a view to achieving full operational readiness by mid-2016.

Built by Damen Schelde Naval Shipbuilding yard in Vlissingen under a contract signed in December 2009, Karel Doorman was laid down in June 2011 and launched in October 2012. Before completion the ship found itself in 2013 declared surplus to requirements under austerity-driven defence budget cuts. The decision was reversed by the Dutch government and it officially entered service with the RNLN on 24 April 2015.

Following commissioning, the ship embarked on a nine-week deployment to Norway, Canada, the United States, and the Dutch Antilles where it conducted warm weather trials, and underwater and magnetic signature testing under DMO supervision. In addition to the DMO’s test programme, Karel Doorman was used for replenishment at sea operations throughout the nine weeks, transport of equipment to the Dutch Antilles, and successful trials with a Bell-Boeing MV-22 Osprey tiltrotor aircraft. It also participated in the annual «Hurricane Exercise» («HUREX 2015»), demonstrating the versatility and potential of the ship, the spokesperson said.

Prior to commissioning, in November 2014 the ship also completed a three-month deployment to West Africa to deliver aid to Ebola-struck countries.

Damen’s new OPV

On 20 April 2015, Damen Shipyards Group gave a sneak preview of their newly designed 2nd generation Offshore Patrol Vessels (OPVs) during the annual OPVs & Corvettes Asia Pacific conference in Singapore. Damen’s Design & Proposal Manager Piet van Rooij explained how this new OPV has been configured for various missions.

The development of the «Axe Bow Concept» followed, a hull shape with unparalleled seakeeping characteristics: the maximum acceleration ever measured on the bow of an existing Axe-Bow is 1.3 G. Based on this concept, Damen has developed the «Sea Axe» Patrol Boats and Fast Crew Suppliers. Damen has delivered over 150 Axe-Bows since 2006
The development of the «Axe Bow Concept» followed, a hull shape with unparalleled seakeeping characteristics: the maximum acceleration ever measured on the bow of an existing Axe-Bow is 1.3 G. Based on this concept, Damen has developed the «Sea Axe» Patrol Boats and Fast Crew Suppliers. Damen has delivered over 150 Axe-Bows since 2006

This new generation of re-configurable Damen OPVs is highly efficient and incredibly versatile. Damen’s famous Sea Axe hull shape is used for these 2nd generation OPVs. Due to this hull design, these vessels demonstrate superior seakeeping including exceptional low heave accelerations. This makes the vessel very comfortable, even in stormy sea states.

Since the hull is designed to reduce water resistance, the new OPV is also very fuel efficient and capable of speeds up to 25/26 knots/29/30 mph/46/48 km/h.

Versatility has been reinvented by three newly developed multi-mission locations – namely the Bridge, Hangar and Bay. The Multi-Mission Bay (MM Bay) can be equipped with dedicated mission modules (e.g. mission containers) for missions such as counter piracy, counter-drug operations, Anti-Mining Warfare (AMW), Search-And-Rescue (SAR) etc.

The MM Bay is also equipped with a nine-meter Rigid-Hulled Inflatable Boat (RHIB), which can be launched over a dedicated slipway through the rear of the vessel while the OPV is sailing. In the Damen-built Holland Class Ocean Patrol vessels for the Royal Netherlands Navy this system has already proven to be safe in operations up to SS 5 conditions.

Unlike other OPVs, the Command-and-Control Centre (C2 Centre) is located directly behind the bridge. Damen calls this development their Multi-Mission Bridge (MM Bridge). Both spaces can be separated by means of a blinded sliding wall. OPVs are less likely to take part in combat situations such as those faced by a frigate.

During a mission, when lowering the sliding wall, situation awareness in the C2 Centre is improved, allowing C2 Centre officers to observe the situation immediately with their own eyes.

Mr. Van Rooij comments: «Today OPVs don’t engage in combat situations as often as frigates do, however, fast and effective coordination during a ‘chase’ is essential for an OPV».

The Multi-Mission Hangar (MM Hangar) is capable of storing an 11-tonne NH-90 helicopter and an Unmanned Aerial Vehicle (UAV) such as the Boeing ScanEagle. The MM Hangar has been designed so that the OPV crew can deploy either the helicopter or the UAV without having to move either one. Furthermore, there is space for a spare parts store and workshop for both the helicopter and UAV.

The Damen OPV 2nd generation is available as a standard in four series:

  • 75 meter/246 feet – 1,400 tonnes;
  • 85 meter/279 feet – 1,800 tonnes;
  • 95 meter/312 feet – 2,400 tonnes;
  • 103 meter/338 feet – 2,600 tonnes.
Depending on the mission and the situation, the C&C Centre can be separated from the Bridge by means of a blinded sliding door
