Counter pollution stockpiles

Updated 23 July 2021

Current stockpile arrangements

The Maritime and Coastguard Agency’s (MCA) counter pollution equipment and dispersant are distributed across several strategic locations around the UK.

There are three equipment stockpiles, situated in Bristol, Barnsley and Dundee. The location of these sites enables the MCA’s contracted pollution responders to reach any part of the coast on the UK mainland and ferry terminals to Northern Ireland within 12 hours. The equipment stockpiles contain oil spill response equipment for use offshore, near to shore and on the shoreline. The equipment is intended primarily for the deflection, containment, recovery and temporary storage of oil. A number of specialist items of ancillary equipment are also kept in the stockpile, including all-terrain vehicles and a portable inert gas generator.

The UK’s 1400 tonnes of Type 3 dispersant are currently stored at eight stockpiles across the UK. Two large stockpiles are situated near Nottingham and Glasgow, in close proximity to East Midlands and Prestwick airports respectively, where the dispersant can be loaded on to the MCA’s aircraft for aerial spraying campaigns. A small quantity of dispersant is kept at each of these airports to enable rapid mobilisation for a test spray. The remaining four smaller satellite stockpiles in Milford Haven, Belfast, Stornoway and Shetland enable mobilisation to response vessels for ship mounted spray campaigns in those areas. This catalogue gives an overview of the MCA’s stockpiles.

Sorbent Boom

Application

Sorbent booms are used to absorb thin layers of spilled oil. They are particularly useful in removing sheens of spilled light oils, e.g. marine diesel fuel. Sorbent boom consists of a fibre filling that absorbs the spilled oil while allowing water to pass through. The fibre filling is a special polypropylene crimped fibre opened and blown into the fabric. The fabric is specially treated to make it hydrophobic (repels water). The material is already oleophilic, (has an affinity for hydrocarbons). The fabric cover is produced from polypropylene yarn, which is woven with sufficient picks to allow total enclosure of the fibre whilst allowing an ingress of oil.

Diesel Driven Hydraulic Power Packs

Application

There are three different types of hydraulically or mechanically started diesel engines which drive hydraulic pumps, all are self-contained with hydraulic oil and fuel oil tanks, mounted on a skid for transportation. These units have no electrical components and insulated exhausts and are therefore are safe to use in hazardous environments. Their primary function is to be used in conjunction with a back-up unit, and cargo transfer pumps, but can be used to power other large hydraulically driven equipment such as large skimmers.

Heavy Oil Pump

Application

A hydraulically driven pump set designed primarily to pump highly viscous fluids such as heavy fuel oil, bitumen, crude or sludge

Specification

The unit comprises a skid mounted diesel driven power pack, pump set and reels with hoses. The pump is a submersible positive displacement pump with a capacity of up to 140m3/hr, and includes water/steam injection and a debris cutting knife in the inlet

Dimensions

2810mm x 1460mm x 1680mm

Location

1 x Barnsley

Spate Pump

Application

Principally used as a transfer pump for oil or water. Can be used for fluid transfer between temporary storage facilities.

Specification

The unit is a self-priming, induced flow, diaphragm pump. When used on water a suction lift of up to 9 metres is attainable, a delivery head of 30 metres is possible and the maximum rated capacity is approximately 30 tonnes per hour. The performance of the pump diminishes the higher the viscosity of the liquid being pumped, meaning the more viscous the oil the lower the capacity that can be pumped.

Weight

Cargo Transfer Pumps

Application

Cargo pumps can be used during salvage operations to transfer oil or chemicals between tanks or to remove oil or chemicals to another ship. The TK series of pump heads are centrifugal pumps. The pump head is submerged in the fluid to be pumped. Two pump heads can be powered by a single hydraulic power pack that is driven by a diesel engine.

Specification

The flow rate of the pumps varies with fluid viscosity and the ‘head’ (vertical distance) to be pumped.

Nominal maximum flow rates are:

Pump Head	Nominal Max. Pump Rate (m3 / per hour)	Static Head (Metre water column)
TK80	80	70mwc
TK5	190	50mwc
TK150	300	60mwc
TK6	500	40mwc

Gas Freeing Fans

Application

These fans fit standard deck openings (12.5”) and can supply air or extract air vapour from a cargo tank. They are air-driven and intrinsically safe meaning they can be used around flammable gases if needed.

Specification

Victor Pyrate Type 850A Moves 8000 m3/hour with a compressed air supply at 7.5 bar Each fan has 10 metre sections of flexible ducting or 2 metre exhaust stack.

Dimensions:

463mm x 590mm diameter

Weight:

25 kg

Location:

4 x Barnsley

General Purpose Air Compressors

Application

Several standard duty compressors are held for normal operating conditions to drive pumps, fans, lighting or tools.

Location

2 x Barnsley

Safe Zone Compressor

Application

This compressor is designated as a ‘Safe zone’ Compressor. This means it is built with additional safety features for operation in ‘safe zones’ on offshore platforms. These safety features include an intake shutdown device that, in the event that flammable gases enter the engine, will shut the unit down. No electrical components are used, effectively eliminating the chance of sparks.

The unit is housed in a DNV 2:7-1 Offshore spec crash frame and lifting rig.

It is used to supply compressed air at 200cfm primarily to drive intrinsically safe air powered lighting, or to drive air driven gas-freeing fans.

Dimensions

2140mm x 2200mm x 1860mm high

Weight

2400 kg

Inflatable Fenders

Application

The Dunlop low-pressure fenders are rapidly transportable and can be easily inflated to provide damage protection during ship-to-ship transfer operations.

There are two sizes that are currently stored as part of the stockpile: a 4 x 1 metre in diameter x 4-metre-long and a 2 x 2 metre diameter x 12 metres long. (Sizes are when fully inflated)

Dimensions

The fenders are transported in cages that are:
2500mm long x 1700mm wide x 1350mm high

Weight

Small fender: 50kg
Large fender: 200kg

Locations

2 x Barnsley (large), 2 x Bristol (small), 2 x Dundee (small).

Self-Contained Lighting Rigs and Portable Lighting Systems

Application

Self-contained diesel driven 8 metre lighting towers consisting of 2 x 1000-watt halogen lamps. 2 x Ampco Intrinsically Safe Light System (1 x generator, 4 x floodlights per system)

12 x Wolf air driven turbo lamps. 6 Units can be driven on a standard air compressor.
