Kanon Marine Loading Systems

 

The transfer of all fluids and liquefied gases, into the smallest barge or the largest crude carrier may be safely and dependably accomplished using a KANON Marine Loading Arm system. These loading systems are manufactured to the latest requirements of OCIMF and major oil companies. KANON’s single counterweight balance system enables both hydraulically and manually operated arms to be manoeuvred easily and safely, saving both time and manpower. KANON Marine Loading Arms require minimal maintenance and all product seals can be replaced without scaffolding or dismantling the loading arm itself.

Characteristics:

 

• Sizes 4" to 24" diameter

• Materials: carbon, stainless and low temperature steels, with PTFE or rubber linings and other special alloys

• Temperature range –200° C to 300° C

 

All KANON arms, including manually operated models, can be provided with a virtually non-spill Emergency Release System. This ensures, that, in the event of an emergency, the liquid and vapour lines are both sealed after disconnection. Once the emergency sequence commences, the arm automatically rises and returns to its parked position, allowing for immediate departure of the tanker if necessary.

 

Accessories:

 

Depending on customers needs, the following options can be offered:

• Vapour return line, piggy back style

• Vapour return line as part of the construction

• Drain, purge, flush, product recovery and pigging systems

• Quick connect/disconnect coupling

• Vacuum breaker

• Shut-off valve

• In-situ replacement of swivel joint product seals (standard provision)

• Isolation flange

• Centralised ‘Tell-Tale’ leakage indicators for all swivel joints

• Adjustable support jack

• Electrical heating/tracing

• Steam or hot oil tracing/jacketing

• Thermal insulation

• Access ladders and maintenance platforms

 

Kanon Loading arm models:

 

The MLA260 model can be configured with more than one fully separated, self-supporting product lines, which are designed to absorb all possible forces associated with structural mass, fluid weight, pressure load and wind load. Full balance of the loading arm is provided by means of a rigid pantograph link, which connects the outboard arm to the rotating counterweight. Special care has been given to the rotating pivots of the pantograph bar both in design and in material selection thus assuring smooth operation with minimum

maintenance. Four different executions are available.

 

The MLA272 consists of a frame type construction including separate supporting structure with floating product and/or vapour pipe. Full balance of the loading arm is provided by means of a fully rigid linked rotating counterweight balancing system. The MLA272 series is specifically used for cryogenic or highly corrosive or toxic chemical service.

Operation:

 

KANON Marine Loading Arms can be operated either manually or hydraulically, depending on product pipe size, physical dimensions and fitted accessories. Hydraulic operation requires 2 drives for inboard and outboard arm movement and 1 drive for slewing (rotation) movement. Operation of the hydraulic loading arm can be effected by means of:

·  Levers directly mounted to the valve block adjacent to the loading arm stand post (manual  hydraulic operation).

·  By pushbuttons on either the operators console or on the remote control pendant  box/wireless set (electric hydraulic operation).

 

All KANON hydraulic and electrical control systems are inherently safe. The hydraulic circuit includes overpressure relief valves adjusted to 190 bar maximum (system pressure maximum 210 bar). Specific details of hydraulic controls are provided in separate bulletins
