Cost effective bulk-loading hose concept
Bulk-loading hoses are manufactured for use, primarily in the oil and gas offshore industry, for delivery of a wide range of bulk liquids and abrasive powders between supply vessels and drilling rigs / platforms.
Active Service provides a range of bulk-loading hoses specially designed and manufactured for the oil and gas industry. Bulk-loading hoses are primarily used for delivery of a wide range of bulk liquids and abrasive powders between supply vessels and drilling rigs/platforms. 

Active Service has extensive experience in the design and application of bulk-loading hoses in the offshore market. Our design and development of the Active Service bulk-loading solution is based on our commitment to safety.

Optional Design features/Accessories

Typically, the hose assembly comprises of the following safety and anti-pollution components:
  • Very Low Friction (VLF) Swivel
  • Active Service’s valved or un-valved weak-link coupling
  • Hose floatation / (optional buoyancy aids)
  • Safety lifting hooks
  • Dry-break couplingsHammer-lug unions
We have standardised our bulk-loading hoses to consist of three sections; platform, floating and supply vessel.

the active service bulk-loading hose concept

The platform and supply vessel sections are more exposed for wear and tear than the floating section. By using noble metals such as AISI 316 and JM7 on hose inserts, breakaway couplings and unions, we can reuse these parts a number of times. Thereby only the worn-out rubber hose is replaced when repairing the hose. The life span of the metal parts can be up to 5-10 years.

Since its inception years ago, the Active Service bulk-loading hose solution has proved to be a huge success. Many of the safety and life expectancy problems commonly associated with bunkering hoses have been resolved.

Floating Hose

The Active Service floating hose is a fully integrated floating hose solution. It is developed in-house, and with a buoyancy that satisfies all the standard media used in bulk loading between offshore platforms and supply vessels.

A fully integrated floating hose gives smoother buoyancy, better visibility, and optimal flexibility in relation to all conventional floating elements. The integrated floating hose also eliminates the problem conventional floating elements have, such as displacement which cause uneven buoyancy. The result is reduces risk of the hose coming into the vessel propeller.

Combined with our own design for both the swivel and breakaway coupling, this is a high quality and high safety solution.

Hose Flotation Elements

The flotation elements are a low cost and simpler alternative to a floating hose for transferring fluids between supply boats and offshore installations. The Flow Safe hose flotation elements help prevent the hose from contact with the vessel and with the propeller.

Flow Safe hose flotation device is made of BACELL plastic, an incredibly shock absorbent, strong and elastic material with 100% watertight cells. In spite of its great strengths, the weight is very low.

Maintenance Program

​Active Service customise maintenance programs for bulk loading hoses, including regular periodic inspections to determine whether the hose is suitable for continuing in service. Generally during maintenance, a visual inspection of the hose and couplings is done for loose covers, kinks, bulges or soft spots which might indicate a broken or displaced reinforcement; evidences of coupling failure. The hose may then be subject to a hydrostatic test pressure if this is available.
