An extinguishing giant protects an ocean liner

The Rosenbauer high-end B60 aerial rescue platform is the new flagship of MV WERFTEN's plant fire brigade.

The new Rosenbauer B60 is currently the tallest aerial rescue platform in Mecklenburg-Western Pomerania, and the pride of the MV WERFTEN plant fire brigade. It reaches a working height of 60 m, is ready for operation in less than three minutes (set-up time), and can be controlled fully automatically. The rescue cage offers space for five people and can handle a payload of 500 kg. With a remote-controlled water turret fixed to the basket rail and a pump system (up to 5,500 l/min at 10 bar) built into equipment compartments 1 and 2, the B60 is immediately ready for use. Extinguishing water, electricity and breathing air are supplied to the basket via special risers. Water can be supplied both from hydrants and directly from the sea, which is why the entire extinguishing technology is suitable for use with sea water.

The high-end platform has been operated by KÖTTER Security since June. In addition to other security and fire protection services, the largest family-owned company in the security industry in Germany manages the plant fire brigade at MV WERFTEN. Rosenbauer had the opportunity to talk to Marcel Bröder (sales manager at KÖTTER Fire & Service GmbH & Co. KG) about the reasons for the purchase of the B60 and the specific operational conditions at MV WERFTEN.

Mr. Bröder, why does MV WERFTEN need such a large firefighting platform?

Marcel Bröder: Our customer builds state-of-the-art cruise ships in Mecklenburg-Western Pomerania. The B60 is primarily used in the jointly developed fire prevention and security concept to contain fires at height. It allows, on the one hand, the potential for the rapid provisioning of an additional water supply for the ship's own stationary extinguishing systems, which are put into service as early as possible during the construction phase. And on the other hand it acts as a secondary route for the fire brigade for extinguishing, and allows the speedy rescue of injured persons from heights.

What ship is currently being built, and what role does the B60 play in this?

Marcel Bröder: MV WERFTEN is currently building the "Global I," a cruise ship of superlatives: 342 m long, 46 m wide and 20 decks high (note: this roughly corresponds to a 22-story skyscraper). This floating city will accommodate up to 9,500 passengers in its cabins, and will be the first ship in the history of seafaring to be able to carry more than 10,000 people.

The colossus of the oceans is being manufactured at the Rostock-Warnemünde (large segment construction) and Wismar (final assembly and interior design) sites. The potential for fire increases with each cabin and with every meter that the ship grows in height. The B60 will therefore largely accompany the "Global I" from one location to another, depending on the progress of construction, and control the spread of any threat at height to the extent that primary defensive measures permit.

Are there any other tasks for the B60?

Marcel Bröder: It goes without saying that, at the Wismar location, the B60 also protects the hotel ship moored there, which can accommodate up to 1,500 shipyard workers, as well as numerous heavy-duty cranes and, of course, the shipbuilding hall with its gigantic dimensions of 395 x 155 x 72 meters. Also, operations at heights in the shipyard area in Stralsund (note: 3rd site of MV WERFTEN) can be supported by the B60, provided that it is not forbidden from doing so for insurance or fire-protection-related technical reasons. Deployment outside the shipyard area is, however, only conceivable if there is no urgent need for measures. In such a scenario, a request for the B60 from an external fire brigade control center would be forwarded to the permanently staffed in-house control center, which would then send an alert as to its requirement.

How is the plant fire brigade at MV WERFTEN organized?

Marcel Bröder: A firefighting squad and a control center dispatcher are on duty at all three locations around-the-clock, and the B60 will also be permanently manned from January 2020. In addition, we operate independent aerial rescue units across all locations, and maintain a high number of medical staff.

In addition to the B60, there is an HLF, a GW-L, an ELW and a material and personnel transporter at each site. Mobile heavy-duty ventilators are also stationed in Wismar and Stralsund. In addition, we have a mobile infeed system for the B60, for situations where it can't be directly connected to a hydrant.

Many thanks for the interview.
