• Hoses with double linings and/or double covers, incorporating a colored wear marker are now standard

Exceptions to OCIMF 1991 Requirements

• Kerosene Testing (Clause 1.11.7)

Ships Lightering Oil Hose Product Range

Using the successful designs of the OCIMF 1991 offshore hose, this range of hose is intended for ship-to-ship or ship-to-shore or other lightering operations where the service may require extra flexibility and hose may be used under tensions that are not usually experienced in sub-marine operations.

Design Features

• Built-in fittings, complete with flange, as required by customer
• Polyester reinforcements
• A single helical steel wire (or helix free of special construction for mainly discharge
operations–specify on inquiry)
• Holding plies and cover of weather, abrasion and ozone-resistant compound


• Hoses are available generally according to OCIMF principles with a nominal working pressure of 300 psi and minimum burst pressure of 1,500 psi
• The standard tube/lining is suitable for high flow rates of 15 meters per second and within a
temperature range of -20°C to +82°C
• Internal diameter sizes in the range are 2-inch through 12-inch, and up to 40 feet in length

Data Sheets

• All data is nominal and users should make clear their specific requirements at inquiry/order
• Hoses are made electrically continuous or discontinuous as per customer requirement, which also must be stated at order/inquiry stage


The offshore transfer of LPG (Liquid Petroleum Gas) requires specific hose design and construction to stand up to the harsh and demanding offshore environment.

Construction of these hoses depends upon the product being transferred and the operational parameters.  Hose system construction requirements vary based upon the temperature of the LPG being transferred, whether it be refrigerated or ambient.

Our LPG sub-marine hoses contain design elements which specifically recognize a potential for LPG to permeate typical oil hose rubber linings. The hose used for LPG should not be used subsequently in oil service or vice versa.

It is critical that the precise operating requirements are specified at inquiry/order stage. These include operating pressures and temperatures, particularly where these may drop to low values due to venting of the lines.

It is always assumed, unless otherwise advised, that the term LPG refers to Propane, Butane, and mixtures thereof. Currently, the LPG hose construction is suitable for product in the temperature range of -30C to +70C.


• Typically the physical hose design complies with OCIMF 1991 for sub-marine hose used on
CBM systems
• Hoses are provided with built-in carbon steel fittings generally in accordance with OCIMF
1991, but if a low temperature is experienced, then fitting materials should be selected
accordingly with T-notch values appropriate to the low temperature requirements
• Low temperature requirements will also affect the choice of tube/lining and potentially other materials in the hose
• Venting of any LPG permeation in the hose carcass is a normal requirement and may
appear as slight bubbling from the cover under water. This protects the tube from explosive
decompression when the pressure inside is suddenly released

UIP International maintains a program of continuous quality and technological improvement. We have a proven track record of reliability and satisfactory performance in offshore and dock side hoses since 2001. We may not build the biggest hoses in the world….but we do build the BEST.


UIP International manufactures all of its offshore products to the very highest industry quality standards.  As required by OCIMF guidelines, all hoses are constructed and
manufactured under exceptional quality systems.

UIP quality control professionals are responsible for assessing all external vendors
who supply goods utilized to manufacture our products.  Raw materials are processed by our skilled technicians on equipment maintained and calibrated to the most rigorous standards.

From the formulation of compounds to final acceptance of a product prior to testing, all stages of production are closely monitored . Our inspectors conduct roving patrols to ensure that all materials are suitable for their intended purpose and that all procedures are being properly adhered to in every facet of manufacture.
• Quality is assured for all offshore hoses through testing of hydrostatic pressure, vacuum, bending and adhesion
• Hose components are assessed for quality through material testing
• Made in America by skilled workers

Customer satisfaction is “Priority One” at UIP.  Our highly skilled team of personnel
work continuously to exceed the exceptional. Our customers can be assured that the quality of our products and service will be one of the highest in the industry. We strive to provide our customers with the highest value for their money.


Regular maintenance of your hose and ancillary equipment will undoubtedly extend the life of your equipment and reduce the risk of pollution. Following these general guidelines will assist you in this goal.

Considerations for Installation

• Establish uniform procedures which will avoid rough handling and over-bending during the
installation process.
• Ensure that contingency plans for inclement weather are in place when planning installation.

Considerations for Operation

Operational procedures will invariably differ from site to site due to weather conditions and tanker frequency. Attention to the following general guidelines will assist in smooth operations:
• Hose handling vessels should be purpose-built, powerful and highly maneuverable (preferably twin screw).  They should have a flat, open stern section, equipped with winches compatible with the weights of hoses in use, and should be in radio contact with the mooring master aboard the berthing tanker.  To avoid damage to hoses during “alongside” maneuvers, boats should be fitted with propeller guards.
• Initially, hoses should be checked daily to become familiar with how they behave during tide
changes. Submarine hoses should be checked before and after each tanker loading, as well as
after storms.
• Hose handling equipment such as tail and lifting gear, should be properly modified if
necessary to suit the preferences and equipment of handling crews.
• Extreme care should be taken to ensure that the rail hose is not over bent. Proper use of
snubbing chains and wires is essential.
• Operation crews need to assess the necessary spare hose requirements and develop a
maintenance schedule based upon this assessment.


Maintenance of submarine hoses is limited to visual external inspections. Following the general guidelines below will ensure the maximum results from your inspections:

• Inspect hoses at zero internal pressure and at full working pressure. Maintenance divers
should inspect hose configuration to ensure that no adjustments are necessary.
• Check the cover of each hose for damage due to chafing. Check each hose carcass for kinks,
particularly at connections to rigid areas of the system (manifold connections and buoyancy
tanks). Inspect bolts for tightness. All flanges and hoses should be checked for leaks under
• System-wide valve arrangements should be such that if a hose failure occurs in one submarine hose in a string, loading can be achieved through the remaining hose string while the failure is being cured.
• Sufficient spare submarine hose should be kept on hand for each applicable size.


Great care should be taken when handling hoses at the terminal. They should only be lifted on a spreader bar which provides 3-point minimum support. They should never be lifted from a centrally placed sling with flanges hanging down or from both flanges with the center hanging unsupported. Do not lift hoses with conventional fork lift trucks.
