WISERISE Dry Chemical Powder Systems

Fixed Dry Chemical Powder for LNG-Fuelled Ships

DCP systems provide rapid knockdown for LNG leaks and pool fires at bunkering stations and gas handling areas. We engineer class-approved packages for newbuilds and retrofits, with spares staged in Shanghai & Singapore.

IGF Code Ready · Bunkering station coverage · Manual-safe release

Applications

Targeted, fast-acting suppression for LNG fuel systems and gas-handling interfaces on dual-fuel and gas-fuelled ships.

LNG Bunkering Stations

Fixed DCP coverage for all potential leak points; manual release from a safe location.

Drip Trays & Transfer Manifolds

Rapid knockdown for pool fires during bunkering/transfer operations.

Tank Connection Spaces

Supplementary protection for gas valve units and hazardous zones as required by design.

Vent/Mast & Gas Handling Areas

Local coverage at critical interfaces; coordinated with shutdown and ESD logic.

Retrofit & Conversion

Add DCP to legacy LNG-fuel installations to meet current class interpretations.

Cargo Gas (IGC Scope)

For LNG carriers: on-deck cargo areas protected by fixed DCP per IGC requirements.

Project Delivery Flow

Aligning with IGF/IGC requirements—from bunkering hazard study to commissioning and class handover.

Hazard & Scope

Identify bunkering station layout, leak points, drip trays, valve units, hazardous zones.

Capacity & Coverage

Define DCP discharge rate and duration; locate nozzles to effectively blanket leak sources.

Engineering & Class Submittal

Nozzle maps, piping, actuation & ESD interfaces, manuals; submit to ABS/LR/DNV/CCS/BV.

Supply & Fabrication

DCP cylinders, valves, manifolds, hoses, release panels; FAT as required by class.

Installation & Commissioning

Functional tests, discharge checks, interlock & shutdown verification at bunkering stations.

Handover & Lifecycle

Class dossiers, crew training, maintenance/inspection schedule, refills and periodic tests.

Compliance & Classification

Designed to meet bunkering safety expectations for LNG-fuelled ships and cargo gas rules for LNG carriers.

IGF Code – Gas-fuelled Ships

Bunkering stations require fixed DCP with safe manual release.

IGC Code – Gas Carriers

On-deck cargo areas fitted with fixed DCP systems.

Revised DCP Approval Guidelines

Latest approval guidance for fixed DCP systems on liquefied gas ships.

Class: ABS • LR • DNV • CCS • BV

Submission, FAT/SAT witnessing per class practice.

ESD/Shutdown Integration

Aligned with fuel gas safety functions and hazardous area controls.

Records & Training

Commissioning records, drills, periodic testing & powder quality checks.

Inventory Snapshot — DCP

Critical spares in Shanghai & Singapore for LNG bunkering stations and gas handling areas.

DCP Cylinders & Valves

Approved powder cylinders, discharge valves, pressure gauges, bursting discs; refill & recert support.

Manifolds & Hoses

Main/sectional manifolds, high-flow hoses and fittings for bunkering coverage.

Nozzles & Discharge Devices

Full-bore nozzles and applicators for effective powder dispersion.

Release Panels & Interfaces

Manual-safe release, interlocks to ESD/ventilation; local indicators & alarms.

Detection & Integration Modules

Interface to gas detection, shutdowns, ventilation & fuel isolation.

Test Tools & Consumables

Discharge verification kits, seals, labels and commissioning consumables.

Customer Guidance & Applications

Key information to prepare for quotation and the main use cases where Dry Chemical Powder systems bring the highest value on LNG-fuelled vessels.

Information Required for Quotation

Vessel type & IMO number, GA of bunkering station and gas valve units
Class and flag requirements; newbuild or retrofit scope
Preferred delivery schedule and ports of installation
Interfaces: gas detection, ESD/shutdowns, ventilation, alarms and HMI
Required discharge performance (rate and duration) and safe release location

We prepare class-ready drawings, manuals, and test records to support approval and onboard inspection.

Recommended Use Cases

LNG bunkering stations and drip trays for rapid knockdown of gas leaks and pool fires
Transfer manifolds and connection areas with potential leak sources
Cargo deck zones on LNG carriers in accordance with IGC Code requirements
Integration with water mist or foam systems to create layered fire protection

Note: DCP systems are specialized and require periodic maintenance and powder quality checks. They are not a replacement for total-flooding systems inside machinery spaces.
