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 OUR Marine Loading Arm system. These loading systems are manufactured to the latest requirements of OCIMF and major oil companies. OUR’s single counterweight balance system enables both hydraulically and manually operated arms to be manoeuvred easily and safely, saving both time and manpower. OUR 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 OUR 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

OUR 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 MLA262 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 “Cable wheel link” rotating counterweight balancing system. The MLA262 series is specifically used for cryogenic or highly corrosive or toxic chemical service.

Operation:

OUR 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 OUR 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
