hoses used for the transfer of any hydrocarbon based products since an increased risk of explosion will result.

       Do not use potable water hoses for transferring other bulk liquids, including ordinary fresh water. The transfer of potable water and fuel at the same time should be avoided.

       Hoses should remain afloat at all times.

Before arriving at offshore installations to discharge liquids, cargo and bulk, the following matters should be checked:

       that the ship can approach the installation safely;

       that there are no divers, ROVs etc in the water;

       that the weather/tide/current/sea and swell conditions are suitable;

       the type, weight and number of units to load or discharge;

       the existing cargo on deck;

       that there is sufficient space on deck to allow safe access to and from the work area;

       that all engine/steering/thrusters/joystick controls have been checked and are fully operational and the main engine pitch control is fully operational;

       vessel's electrical load must be carried by auxiliary alternators and is not totally reliant on shaft alternators; and

       hose connection points on the vessel are in good order.

Before proceeding with the cargo operation the person in command must ensure that:

       all emergency pump stops are operational;

       the vessel is able to remain on location in the prevailing weather and sea conditions;

       correct couplings have been identified for the products to be transferred; and

            constant communication is maintained with the person on the platform responsible for supervising the transfer of hoses and receiving of cargo.

The hose terminations should be colour-coded by use of a coloured band to mark the product, and all support vessels and installations should adopt a universal colour and connection scheme as follows:

Hoses should only be lifted by a certified wire strop on a certified hook eye fitting. Hoses should be secured to the vessel by a rope lashing before disconnection from the crane. Further rope lashings at appropriate places will minimize 'kicking' of dry bulk hoses.
When the hose is connected and installation lines are set, the support vessel should be instructed to start pumping at a slow rate. If no leaks are observed,
