The enhancement aims to better protect vessels running on LNG and LPG. The upgrades received type approval certification and are now being specified for newbuild and existing vessels.
Since receipt of DNV certification, Survitec has received orders for installation on a 16,000 TEU container ship with an estimated beam of more than 50 meters, under construction at a South Korea yard.
'The Survitec DCP system offers comprehensive bunkering station protection, cost-efficiency and versatility for a variety of vessel types, whether newbuild or retrofit,' according to Rafal Kolodziejski, head of product support & development - fire systems, Survitec.
'Dry chemical powder systems have long safeguarded LNG and LPG cargo vessels, but as the industry embraces liquefied gases as a propulsion fuel, the unique requirements for protecting bunkering stations on a wider range of vessels, such as large cruise ships, container ships and tankers, is becoming increasingly important.'
The newly enhanced DCP system from Survitec comprises an extinguishant storage container, nitrogen gas cylinder and safety valves. It comes with a pressure regulator, piping and discharge devices, including nozzles.
Survitec said the development that sets its DCP system apart is that longer lengths of discharge piping can be combined with smaller volumes of powder to optimize fire protection for bunkering stations and fuel-switching operations on a broader range of vessels. This is achieved through more precise control over propellant and powder mixing and a new delivery nozzle design.
While the recent DNV certification allows pipe runs to be increased from 20 meters up to 69 meters, longer pipe runs can be used on a case-by-case basis. For shorter pipeline lengths, it is now possible to use a more straightforward powder driving solution that enables smaller nitrogen cylinders.
