Alfa Laval option aids fix problems triggered by high paraffin material of IMO 2020 certified gas
Seaspan Ship Management has actually resorted to Alfa Laval to assist it fix vapor equilibrium as well as redundancy problems come across with low-sulfur gas. The thorough option– an incorporated vapor central heating boiler plant making up oil-fired vapor manufacturing, waste warm recuperation, progressed control as well as connection– will certainly quickly be executed on 8 Seaspan- had big containerships.
Seaspan Ship Management decided to fulfill the IMO 2020 international sulfur cap limitations by utilizing certified low-sulfur gas in its container vessels. Like most containerships, nonetheless, the Seaspan had vessels have just a solitary oil-fired central heating boiler as well as a waste warm recuperation central heating boiler aboard. This gives no redundancy, which is bothersome when making use of sulfur-compliant gas.
“The composition of low-sulfur fuels was uncertain when we first decided for them, but it quickly became clear that high paraffin content would be an issue,” claims Arvin Dsouza, fleet supervisor atSeaspan Ship Management “To avoid wax formation, the fuel temperature has to stay above the pour point at all times. But the existing boiler solution on the above-mentioned vessels can’t guarantee the required steam capacity as these vessels do not have heating coils in all the designated fuel oil tanks and rely on a shifter system. We chose to work with Alfa Laval, who found the answers we needed.”
3 CENTRAL HEATING BOILERS SERVING AS ONE RELIABLE SYSTEM
To protect an adequate as well as dependable supply of vapor, consisting of full speed plant redundancy, Alfa Laval recommended reconstructing the existing oil-fired central heating boiler as well as including a brand-new Alfa Laval Aalborg oil-fired central heating boiler. This will certainly sustain gas home heating through vapor coils in all containers. Both the oil-fired central heating boilers as well as the waste warm recuperation central heating boiler will certainly be adjoined with the Alfa Laval Touch Control system, developing a solitary vapor option.
“Alfa Laval is unique in having all the boiler, burner and control technologies in-house,” claimsDsouza “They presented a complete heating solution that keeps as much as possible of the existing equipment on board, but which integrates the different components for smooth performance as one system. With their knowledge, they could tie everything together.”
SMOOTH ASSIMILATION As Well As VERSATILE CONTROL
On each container vessel, Alfa Laval specialists will certainly remove out as well as change the electric elements of initial oil-fired central heating boiler, which was provided by a various maker. However, they utilize its stress area, ring line devices as well as heater to produce a brand-new central heating boiler with the ability of being linked to the Alfa Laval Touch Control system. For a smooth option, the exact same sort of heater will certainly be utilized on the brand-new Aalborg central heating boiler.
“Rather than replacing the competitor burner with their own, Alfa Laval is incorporating the same type, so that we can make use of the knowledge and parts we have on board,” claimsDsouza “Everything, including waste heat recovery, will be smoothly handled through the Alfa Laval Touch Control system, as if it had all come from Alfa Laval in the first place.”
The Alfa Laval Touch Control system, which will certainly change the older central heating boiler’s relay-based control system, is a PLC-based system that can run the oil-fired central heating boilers in either master/slave or load-sharing settings.
“We’ll have complete operational flexibility,” claimsDsouza “Through the graphical touchscreen, the operators will have a full overview of the steam plant and be able to make adjustments with just a touch or two.”
ATTACHED FOR STRONGER ASSISTANCE
Beyond the opportunities supplied by the control system, the brand-new central heating boiler option will certainly be geared up for connection. Alfa Laval solution specialists will certainly have the ability to check the system’s problem from another location, developing chances for repairing, aid as well as optimization. Based on accumulated information, as an example, they will certainly have the ability to direct the team in executing needed upkeep treatments or timetable area solutions like burning adjusting when needed.
“Connectivity will give us deeper and more continuous contact with Alfa Laval service expertise,” claimsDsouza “It will mean peace of mind, but also more effective and cost-efficient use of our boiler systems over time.”
SETUPS
Seaspan Ship Management will certainly apply the arrangement on the initial container vessel in very early springtime of 2020. Installations will certainly after that continue the staying 7 vessels, running throughout 2020 as well as right into 2021. The installments are intended to happen in a shipyard, yet they can be done mixed-up if unpredicted interruptions in shipyard routines make it needed.
“We will be able to move forward with the projects, even if circumstances mean we can’t install at the yard,” claimsDsouza “Alfa Laval has the capability to deliver the parts and install them while the vessel is underway. Whether the installations happen in dry dock or at sea, we’re confident in the solution and we know we count on Alfa Laval’s quality and efficiency.”
