Prigorodnoye Export Terminal Port Regulations Rev 01 OCIMF recommended ancillary equipment of shackles, support buoys and 76 mm chafe chain to allow connection to any general trading tanker fitted with an OCIMF compliant stopper. The hawser mooring connection on the TLU will be fitted with a load monitoring device. This will record loads in the hawser which will be used to determine hawser life, and to assist in determining when the tanker is to abort the loading and depart from the TLU due to excessive mooring loads through weather or ice effects. The loads will be transmitted and recorded in the terminal and on board the tanker by a special device. Each location will have an alarm at pre-set values. The strain recorded will be measured for peak gusting criteria by the Loading Master to assist in assessing if aborting is required. During the winter period, the tanker end of the hawser will be lifted to the boom head and will hang in a bight above the sea ice. This will be operated from the TLU. During the non ice period, the floating hose will remain in the water, and the free end of the hawser will remain in the sea. The hawser will be secured to a point on the floating hose so that both the hose and hawser will be free rotate around the TLU under the influence of the wind/currents, without the risk of the two becoming entangled. (Note the hawser may be stowed at all times from the boom head, but it is considered preferable to leave it in the water as the operation will not be dependant on the winch arrangement). 14.1 Summer Hawser The summer hawser will be retained afloat between tankers, the free end will be secured to a point on the floating hose to prevent it becoming entangled with the hose or the base of the TLU. The end of the hawser will have a support buoy attached to the shackle attaching the chafe chain to the hawser. Shackled to the shipboard end of the chafe chain is a 20 metre long section of 10 inch circumference polypropylene rope. This will float and can be secured to the floating hose with a small messenger rope. The mooring boat will shackle a second messenger, approximately 200 metre long polypropylene rope, 10 inch circumference. The rope will be kept on the deck on the workboat when not in use. Once connected, the workboat will stream the messenger and move to a position at the extreme length of the hawser and messenger arrangement, down wind and current from the TLU to await the approach of the tanker. 14.2 Winter Hawser The winter hawser will be of the same construction and have the same tanker end fittings as the summer hawser, however, the ship end of the hawsers will be winched to the head of the boom and the hawser will be suspended clear of the water surface. The hawser will require a retrieval wire to be fitted for this operation. The lower end of the retrieval wire/chain will be secured to the shackle joining the hawsers to the chafe chain, and the upper end will be secured to a marker buoy, or (by rope) to the support buoy. The retrieval wire/chain will be attached to the boom head recovery wire attached to a dedicated winch on the deck of the turntable. The end of the hawsers will be held in place at the head of the boom between tankers. 14.3 Hawser connection The support craft, tug or mooring boat, will be remain in a position approximately 250 metres 0000-S-90-01-P-0207-00-E Page 38 of 101 BM Code: EP.14.03.01.09
Prigorodnoye Export Terminal Port Regulations Rev 01 down current from the TLU as the tanker makes the approach. This will be at the extent of the ‘stretched out’ messenger. The tanker will prepare a small messenger rope, which will be lowered over the port side in way of the break of the forecastle to the water. It will be lead through the forward lead through the stopper and to the mooring winch. (See preparation in 15.1). When the workboat is alongside the tanker bow, it will connect the hawser messenger to the ship messenger, and then move clear of the tanker. The tanker will commence to heave in the messenger, and continue to do this as the approach to the TLU is made. Note that the tanker speed will be minimal and adjusted so that the messenger can be heaved in without having a large bight in the water. As the hawser end is brought up, the chafe chain will pass through the forward fairlead and into the tanker chain stopper. When there are sufficient chain links in the stopper, the stopper ‘bar’ can be lowered and secured, and mooring considered over. The tanker will be stopped at this time to maintain a separation with the TLU. The pull back tug can be used from this point to prevent the tanker moving towards the TLU and to reduce “fishtailing” motions of the tanker. 15 TLU berthing procedure 15.1 Pre arrival Preparations The pre-arrival message contains instructions on the mooring procedure and preparations for tanker is to make prior to arrival during the summer. On the forecastle a fixed winch drum is to be clear of all wires and able to take the 200 metre messenger. A small rope messenger is to be provided by the tanker along with a bow stopper to be used. At the time of boarding the tanker, the Loading Master and his assistant, will inspect the forecastle and manifold arrangements to confirm they are ready and compatible with the TLU mooring and hose connections respectively. This will ensure that there is an empty fixed drum on a mooring winch with which to heave in the hawser messenger. 15.2 Anchors The anchors shall be secured in the sea going condition before the tanker enters the Offshore Security Zone. 15.3 Manifold During the summer season, the port side amidship manifold blanks are to be removed and two 16 inch couplings prepared. The manifold crane or derrick is to be ready to bring on board the hose connecting equipment, weather permitting, when the Loading Master boards. If the weather is unsuitable, this operation may be performed after completion of mooring operations. This box contains all of the necessary chains, hooks, lifting strops, spanners and gaskets to secure the hose at the tanker manifold ship side saddle and to make the connections to the manifold. 0000-S-90-01-P-0207-00-E Page 39 of 101 BM Code: EP.14.03.01.09
